Joan Watson (Lucy Liu) is hired to be the sober companion of Sherlock Holmes (Jonny Lee Miller). When she goes to meet her new client, she finds that he escaped from rehab the day of his release. When she meets him, he takes her on the subway to a house in Manhattan; he explains that before he began using drugs he used to work for Scotland Yard as a consultant to help solve homicides. He works on the case of a woman who was attacked, and supposedly kidnapped, only to find that she was hidden in a safe room in the apartment. The next day, Sherlock finds that the killer is most likely a serial killer, finding similarities to another case, except that this victim survived. After interviewing the woman, Sherlock and Joan find that she knew the man who attacked her. When Sherlock calls NYPD Captain Thomas Gregson (Aidan Quinn) with his newest lead, Gregson reveals that they are at the suspect's house, and that said suspect has committed suicide. Joan and Sherlock fight, due to his lack of trust and sharing regarding his past before drugs and his mysterious personal life, resulting in her saying she will request another companion assignment. Sherlock concludes that the victim's psychiatrist husband plotted to have her killed by giving his patient pills that would make him violent, then sending him after his wife. There was a pre-nuptial agreement, and he would have received the money if his wife were to die.

Sherlock and Joan investigate the murders of two illegitimate children of a wealthy businessman, but matters are complicated when a witness identifies a woman in a coma—and the man's legitimate daughter—as the murderer.

Sherlock and Joan investigate a child abduction case which involves a serial killer known as "the Balloon Man", whose name comes from the fact that balloons are left at each of his crime scenes. Matters get complicated when the Balloon Man's first victim from 2005, Adam Kemper (Johnny Simmons), is caught by the police. Sherlock deduces that Adam has Stockholm syndrome and sympathizes with him to help find the killer. The Balloon Man is identified as Samuel Abbott, but Abbott commits suicide, allowing for the release of his most recent victim. Sherlock investigates Abbott's home and finds evidence leading to his realization that Adam is, in fact, the Balloon Man. Following a brief confrontation with Sherlock, Adam gets an immunity deal clearing him from all charges on crimes committed "in consort with Samuel Abbott a.k.a. the Balloon Man", but Sherlock is able to arrange for Adam's arrest when he determines that one of the crimes had to have been committed by Adam alone, as Abbott was in the hospital when the abduction occurred.

While questioning hospital doctors and staff, evidence begins to mount, and Sherlock realizes that he is chasing an angel of death. Meanwhile, Joan manages to reconnect with an old friend while working with Sherlock at the hospital. While sitting in on a pre-op procedure, she comes to realize that Sherlock is not the only one with an uncanny sense of intuition.

Sherlock brings Joan to the site of a plane crash on a beach; among the four victims, he deduces that one of them was murdered. Reviewing further evidence including a recording of the sounds heard on the plane prior to the crash, Sherlock comes to the conclusion that sand was used to jam the plane engine and the murder victim was a man who walked in on the perpetrator at work, his corpse then stuffed in a trunk that caused weight imbalance and the plane's subsequent crash. All evidence points to a plane mechanic who is supposedly smuggling cocaine, but further evidence shows that the real murderer is the mechanic's boss. Joan, meanwhile, is called to dinner by Sherlock's father, who Sherlock claims would never propose such a thing. Joan meets a man claiming to be Sherlock's father, but his cover falters when he laughs at Joan's reaction to a question about sex. Joan later meets with the man (Roger Rees), a former stage actor and friend of Sherlock named Alistair.

Because they went to jail for the crime, the vault company cannot imagine how anyone else got in.

While most of the theories are nonsense, Sherlock does find one that seems possible. In 2009, a group of people were hired by the government to devise a terror plot for a war game simulation. In all other cases, these plots were made public after the fact, but the 2009 exercise was kept classified.

She and Sherlock have a past and their association ended when she published an article profiling Sherlock that predicted his forthcoming addiction. Even though Sherlock and Drummond do not get along, they both have a similar idea of what Ennis is likely to do next. The only problem is that the killer is not cooperating and his increasingly erratic behavior has the experts stumped until Sherlock realizes that Ennis is out to avenge himself on Drummond after her false accusation that his parents abused him led to their suicide and early deaths. Watson leads Sherlock to realize that Ennis' plan involved his willing sister who also wants revenge.

After Lydon kills his driver, however, Sherlock finds himself intrigued enough to take the case. Sherlock begins to believe Lydon when a scientist at a corporate genetics laboratory tells him that giving someone the disease is theoretically possible, but the trail runs cold when she turns up dead.

Sherlock and Joan are handed a case of a woman who disappeared 6 months ago. She had left behind only a video addressing her husband and the video reflects on life after the news of a woman who was killed by an oncoming train. Sherlock thinks this case would suit Joan to start her first solo investigation. Meanwhile, Sherlock starts the investigation of the murdered woman at the railway, where CCTV shows an unidentified male who hands her a bouquet of flowers and then comes back to push her off the platform. Joan questions the husband of the disappeared woman and when her instincts tell her he is suspicious, she starts her investigation. Joan follows the husband and when she saw that he possessed a wooden body-sized trunk which he claimed his wife took along with her, breaks into his car. But that does not reveal anything and Joan is arrested by the police. After this failure and remarks from her friends, Joan starts doubting her decision to become a detective, but later her instinct is proved correct when she finds evidence that links both cases of the murdered woman at the railway station and the missing woman, whom she now knows have both been murdered - the wife had actually sent the video 18 months before and not 6 months before and the husband had recreated the death by train of a woman with flowers to make the incident recent enough for the video to pass for only 6 months old.

They meet Pam (Becky Ann Baker) who drives the pair around New Jersey in a snowplow. At EROC Sherlock realizes the burglary has already taken place - $30 million in used notes about to be shredded - and the loot removed by ambulance. NYPD enquiries at hospitals puts the shot criminal into custody but she refuses to reveal the whereabouts of the loot-filled ambulance. Meanwhile, Ms. Hudson (Candis Cayne), an old friend of Sherlock's, is dealing with a break-up and stays at the brownstone. Sherlock realizes that an escape route out of the city for the ambulance has been cunningly plotted with roadblocks being removed one by one. The visiting FEMA official helping out with the city's emergency response to the snowstorm is revealed to be involved with the multi-million dollar heist, proven when NYPD set a distraction which allows her to rescue the arrested criminal. The pair are apprehended and they reveal the ambulance's location. Sherlock tells Joan that Ms. Hudson will be cleaning the brownstone once a week.

Sherlock's first anniversary of being sober is approaching, an event Joan thinks Sherlock should celebrate. Citing uninterest in giving the day any special recognition, he spends it doing business as usual as he and Joan hunt for a blackmailer (based on the villain in the Sir Arthur Conan Doyle story "The Adventure of Charles Augustus Milverton") who targets the fathers of rape victims and even the rapist - the blackmailer relies on an advertised 'fail-safe' accomplice who would put the materials (DVD of the rape) online in the event of his arrest or demise. Sherlock has no trouble identifying Milverton as the blackmailer but while secretly in his house he sees Milverton shot to death by a masked intruder who then removes Milverton's body and laptop. Sherlock takes the rest of Milverton's documents including a blackmail ledger which identifies the 'fail-safe' as "Henry 8", whom Alfredo recognises as a sheriff (corpulent like King Henry VIII). Pistone, one of the blackmailed fathers, is arrested trying to dispose of Milverton's body. He confesses but will likely receive a short sympathetic prison sentence. Sherlock finds "Henry 8", murdered nearly a week before. Pistone had had Milverton take him on as the new 'fail-safe', and Milverton killed "Henry 8" as he did not need two accomplices. Pistone then killed Milverton and stole the laptop containing the blackmail material, intending to take over his blackmail operation and willing to serve a short prison sentence in order to do so. Sherlock confides to Joan the real reason why he is reluctant to celebrate his "sober-versary".

The security expert confesses to the mechanic's murder, but Moriarty says the murderer has not been found. Sherlock discovers that the security expert did not see the murderer flee 20 years ago. It was instead his wife who saw the murderer. When her husband's mental health was failing, she convinced him that the lookalike mechanic was the murderer; this revenge stabilized his mental health. It is proven that the mechanic was innocent, having been out of the country at the time of the sister's death. The security expert's wife is also arrested for the mechanic's murder. In payment, Sherlock receives an address and a choice to lead a safe life or find out about Irene. He lies to Joan, who sees through this and joins him.

He agrees, but then notices a mole is missing from Irene's back and concludes it was removed to avoid it turning cancerous - which Moriarty would not care about, unless she was working for Moriarty. Berating him for not trusting her, Irene storms out. One of Moriarty's agents discovers he is to be killed, but defeats his assassins and returns to kill Sherlock (in defiance of Moriarty's orders).

The nail, the firing trigger, was disguised as a wall-hanger for a piece of art. Tracking 3D printer purchases leads them to the body of the suspect's handyman, and plastic fragments found on the scene prove Sherlock's hypothesis that the man printed a gun to kill his wife and killed the handyman to clean up loose ends.

Gale reveals to them that Haley was not his mistress, but rather his illegitimate daughter as a result of a one-night stand during the early years of his success. Evidence points to Gale's wife (Margaret Colin) due to an inheritance agreement to Haley, as well as medical precision used during the murder; however, Mrs. Gale's arguments during an interrogation are valid and she informs Joan that she arranged the inheritance agreement herself. The detectives locate Haley's former boyfriend, and though the man is innocent, he informs them that Haley was suffering from a illness. Ian Gale dies, prompting Sherlock, Joan and the NYPD to confront Mrs. Gale at her home with the murder of both Haley and her husband: she injected Haley with a poisonous medicine that would also poison Ian during the resulting transfusion and Haley was killed to remove loose ends. In a subplot, Mycroft, who plans to return to London soon, proposes to Sherlock that he come along, as their father apparently desires it. Sherlock shares this with Joan and takes time to contemplate it, even favoring it at one point, but ultimately decides against it with a letter he gives to Mycroft to pass on to their father.

They have dinner with him, and the following day, he proposes a relationship with Joan. While taking time to consider it, Joan meets with Sherlock at a park he found based on a clue in one of Paige's songs. Upon investigation, the pair find not one, but two bodies, one being Paige's and the other of a man, Zach Piller, who they learn manufactured UAVs for a company called McCarthy-Strauss. Sherlock visits Mycroft at Diogenes to discuss Joan, but notices a shady-looking man at a corner table who frequents the restaurant. Sherlock later identifies this man as one Guillaume de Soto, a high-ranking member of a French drug cartel and gang called Le Milieu. He captures an insect-like drone that was spying on him in the brownstone, realizing that the two victims were killed by the drones Zach Piller manufactured. They learn from Piller's psychiatrist that he accidentally massacred 10 undercover CIA agents in Afghanistan and subsequently wrote a report on it out of guilt. During the interrogating, the psychiatrist is poisoned by another drone.

Yoder is interrogated that night at the brownstone and eventually tells them of the hard drive the list is on. After recovering it, Sherlock decides to call the NSA, fearing that Le Milieu will betray them, but Mycroft, who is under orders from an unnamed British contact, incapacitates Sherlock with a taser and heads out to meet with the dealers, while the NSA later refuses Sherlock's requests to save Joan. Mycroft, meanwhile, gives Yoder and the list to the dealers, but de Soto orders them killed and leaves. Mycroft suddenly calls in paramilitary forces, who gun down the dealers. He apologizes to a shocked Joan and says that they have a lot to talk about.

Sherlock returns home to find Joan safe, and Mycroft reveals that he is working for MI6. The Holmes brothers have a talk, in which Mycroft discloses that MI6 utilized his observational skills to investigate criminal groups such as Le Milieu, and that his handler wanted Sherlock out of New York. The two then meet with the handler, Tim Sherrington (Ralph Brown), who employs Sherlock with a murder case involving one Arthur West, an undercover MI6 analyst. West's body in the morgue is shown to have the arms severed and stolen. The two visit West's wife, Marion (Emily Bergl) and learn that she is a tattoo artist; Sherlock later deduces that West's arms were tattooed using invisible ink, thus providing motive for someone to steal them. Joan, meanwhile, angrily rejects Mycroft for his deception. Marion visits the brownstone to inform Sherlock that she was aware of West's activities, which West divulged out of paranoia and reassurance of his sanity to her, given that he was diagnosed with bipolar disorder. Showing them photos of West's arms tattooed with numbers, Marion explains that West was confident of a mole working within MI6, communicating with one Julian Afkhami, a local bookstore owner. Joan later tells Sherlock she plans to move out of the brownstone, which Sherlock dismisses as a mere emotional repercussion following her kidnapping. The following morning, Sherrington meets with Sherlock at a park and eventually offers him a job at MI6. Marion, meanwhile, tells Joan about one "Sudomo Han", who Joan visits Mycroft to ask about. She is shocked to learn that Mycroft joined MI6 to protect his brother, who unwittingly made himself Han's associate, not knowing that Han was a terrorist. Moved, she kisses Mycroft and the two eventually have sex. Elsewhere, Sherlock learns from the NYPD that the gun used to kill West led to untraceable fingerprints bearing a distinctive scar. Immediately identifying the prints as Mycroft's, Sherlock visits his brother's home to inform him that he is being framed as the mole.

Sherlock informs Mycroft that he is being framed as the mole and relocates him and Joan to a vacant, remote library accessible only to Sherlock. While he stalls MI6 with fraudulent "updates", Sherlock continues his investigation into Arthur West. Sherlock and Joan discover that West's arm tattoos signified dates, times and locations mapping out the mole's whereabouts and present their evidence to Mycroft, who notices that he was in every listed location at the corresponding dates and times. Realizing he is being framed because the mole was in the same places as Mycroft, Joan names Mycroft's handler Sherrington as the mole; they decide to keep it quiet until the time is right. Sherrington, however, visits Joan at the brownstone to confront her, but Joan, who is keeping members of the cyber-hacker group "Everyone" on a video chat in order to incriminate him, calls it a draw and sends him away. In the meantime, Sherlock learns that Sherrington made 17 calls to his contact, Iranian Julian Afkhami, feeding information to the Iranian government. Joan confronts Sherlock about Sudomo Han and his history with Mycroft, which Sherlock brings to his brother as a means for forgiveness. Sherlock and Joan investigate a murder believed to be linked to Afkhami and both incriminate him to the NYPD, presenting evidence that he stoned his wife's lover to death, and get him arrested. Mycroft visits Sherrington at a restaurant and learns from Sherrington that he betrayed MI6 because of a lack of promotions or respect. Shortly afterwards, the NYPD finds Sherrington's corpse, which Sherlock confronts Mycroft about at the brownstone. Mycroft informs him and Joan that he made a deal with the NSA for them to kill Sherrington and fake Mycroft's own death, thus making him disappear to protect him from Le Milieu. Joan is deeply saddened, while Mycroft emotionally apologizes to an unmoved Sherlock. While Joan makes plans to move into a new apartment, Sherlock visits MI6 to tell them he is willing to enlist in the organization.

The store's only employee, Amit Hattengatti, has an alibi. Sherlock finds a hidden safe containing Moshe's ledger in Hebrew and code. From shipping manifests and cloth the safe was lined with, Sherlock deduces Moshe was a diamond smuggler. Robbery is ruled out as a policeman finds Moshe's briefcase (with attached handcuff) full of diamonds in a dumpster. Sherlock proves that a strong man can rip someone's hand off if they break the wrist first. At a nearby gym, Sherlock suspects weightlifter Dana Kazmir, and contrives to obtain a sample of his blood/DNA. They match the DNA found under Moshe's fingernails. Kazmir confesses to the murder. The trail to the man who hired Kazmir as hit-man seems to point to Leonard Oosthuizen. The NYPD intercept a cash payment to Kazmir and Kitty recognises the envelope as matching the office supplies of Moshe's shop. Sherlock realises Leonard is a fall-guy, and that Amit was actually Moshe's smuggling partner, who wanted Moshe's share. He had plotted with Kazmir and Kazmir's corrupt lawyer to make it look like he was a murder target to deflect suspicion. Amit went to the same gym as Kazmir. Kazmir, doomed to jail anyway, lied in return for a payout for his family. Told that if he confesses before Kazmir's lawyer does he will get a deal, Amit names his diamond supplier.

Five test subjects were injected with varying dosages. The higher the dose the madder they went (under the influence, one killed the missing acquaintance who was the nurse who administered the drug) and they die or, like the nurse, are found murdered. Carlisle, on the lowest dose, survives and his interview leads to the name of a newly created pharmaceutical company called Purgatorium which paid $150,000 to test subjects and the identity of the drug's inventor, namely, Dwyer Kirk, who accepts responsibility for the deaths but refuses to reveal who funded him. But Sherlock traces the sponsor - James Connaughton, whose past charity fund had given a youthful Kirk a leg-up and gave his aunt a stipend to help raise him. When Connaughton learned he was dying he approached Kirk who, owing him for help in his youth, agreed to develop a "pharmaceutical fountain of youth" so that its time-dilating properties would make his last days feel like years, and he ordered the trial's participants executed to cover it up but Connaughton refuses to confess or co-operate. Sherlock and Watson appeal instead to his new nurse, Brett Won. Shown photos of the dead victims and asked to give their families closure, Won is able to connect Connaughton directly with Purgatorium and with the two hitmen he employed to murder the test subjects. But when Sherlock revisits Connaughton, he finds the man has effectively committed suicide by injecting himself with EZM-77 to "extend" his period of freedom before arrest, and the drug will destroy his brain and kill him.

An elderly couple both died in bed at the same time. Sherlock says they are a casualty of another crime committed elsewhere in the building. Someone burned rubber in the basement, which emitted a toxic gas. Sherlock finds a burned body with a tire around his neck. Clay Dubrovensky was the second floor tenant who worked for the SDS Cartel, growing marijuana for them. The marijuana plants are dying, which Watson and Sherlock find strange. If the cartel had killed Clay, they would have taken care of the plants as well. Sherlock discovers a rare orchid in the greenhouse. Sherlock thinks that Clay may have bought and sold the flower in an auction. Sherlock and Watson meet with Barbara Conway from AgriNext. She bought the orchid from Clay and Sherlock accuses her of killing him when he did not give it to her. She shows them her plant. Sherlock examines both plants and realizes Clay cloned the orchid. There are two more murders by a burning tire necklace, including one right in front of AgriNext. Sherlock notes the rope was different from the rope used in Clay's murder. They speak again with Barbara Conway. She admits that AgriNext offered Clay a job and was trying to buy out his relationship with the SDS. The police arrest the SDS member guilty of the AgriNext murders. He denies killing Clay. Joan meets with Clay's ex-girlfriend. She needed to get plant food from his apartment. He apparently gave all of his girlfriends a special plant. Barbara Conway meets with Joan. She starts in about who might have killed Clay and Joan interrupts her, telling her that she knows that she killed Clay because he was seeing his ex-girlfriend again.

Sherlock and Joan delve into the background of the murdered woman Sherlock was alerted to, at the end of the previous episode, whose premortem injuries resemble Kitty's conditions during captivity. Joan retrieves a burner phone from a bar the woman was at previously, leading the NYPD to a suspect, Simon DeMerville (P. J. Sosko). Simon is found to be a working for a brothel that kidnaps illegal immigrants, and inspection of his property yields the discovery of the body of one of the brothel's suppliers, among numerous women. The detectives suspect Simon was injured during the confrontation and went to his sister Violet (Tammy Blanchard) for medical assistance. Suspecting Violet of knowing more than she claims to know, Kitty visits her house and beats her into cooperating with the NYPD, resulting in Violet making a call to Simon to allow the NYPD to triangulate the call. Sherlock deduces that Simon is aboard a boat, which the NYPD learns is owned by a local bartender (David Valcin) who is an old acquaintance of Simon's. However, the bartender's house (where Simon's boat is being kept) is found scorched with Simon's body inside. At the morgue, Kitty inspects the body and learns that Simon was not her rapist, as she had broken her captor's fingers in her escape, and Simon's fingers are intact. Later, Joan, who has successfully settled into her new job at the insurance firm, makes a call to her new boss, Del Gruner (Stuart Townsend). Kitty, overhearing the conversation, becomes distraught when she recognizes Gruner's voice and names him as her rapist.

All parties' suspicions are aroused when Del Gruner abruptly fires Joan from her job. His questioning at the NYPD proves unsuccessful, so Sherlock begins exploring the backgrounds of various kidnapped women subject to Gruner's modus operandi. They track down a woman named Tabitha Laird, a coworker of Gruner's at a charity he donates to. After Joan suspects a deeper connection between Gruner and Laird, Sherlock learns that Laird's adoptive son is in fact the biological child of Gruner and one of his rape victims on Sherlock's list. Though the NYPD has something to incriminate Gruner with, Kitty lies to Sherlock about leaving New York and captures Gruner. She prepares to kill him and dissolve his body using a recreation of the nutmeg concoction featured in "The Adventure of the Nutmeg Concoction", but Sherlock arrives; however, rather than talking her out of killing Gruner, he compares her situation with his and tells her that she will always be his friend. Kitty becomes emotional and relents from killing Gruner, but instead burns his face off using the concoction and leaves him to be found by the NYPD. She later leaves for an unknown location. Throughout the episodes, flashbacks chronicle the origin of Sherlock and Kitty's partnership in London eight months ago.

When a debt collector is murdered, Sherlock and Joan try to narrow down the pool of suspects from thousands of consumers who owed the victim money. Meanwhile, Joan's romantic relationship with Andrew progresses when he asks her to meet his father for the first time.
62	14	"The Female of the Species"	Lucy Liu	Jeffrey Paul King	February 12, 2015 (2015-02-12)	7.91[63]
As Joan mourns Andrew's death, Sherlock enlists Detective Bell, who is on his day off, to help him find two missing zebras...with surprise pregnancies — foals that resemble a previously extinct zebra subspecies known as the quagga. A trademarked color provides the first clue that leads to the thief, an employee of the zoo. Later, Joan receives a letter from Moriarty, who informs Joan she had Elana March murdered because March intended to kill Joan instead of Andrew. After Sherlock tells her that there was little chance to trace the murder back to Moriarty, Joan tells Sherlock that she wants to move back into the brownstone.

Sherlock and Joan investigate a series of murders in which the killer leaves envelopes of cash on the victims equating to their "worth". The probe leads the two to investigate an airline crash which killed over 80 people and the amount that each, depending on their "worth", would receive as wrongful death compensation. Sherlock and Joan realise that the killer is plotting to have the airline switch their method of calculation to making the same payment to every bereaved next of kin - a switch that seemingly is a disadvantage. Meanwhile, Joan moves into the basement at the brownstone, and seals the interior door so that in future she will have a physically separate space but still be able to work closely with Sherlock.

Detectives Demps and McShane, 35th Precinct, investigate the murder of Maria Gutierrez who vanished 3 years ago in December 2011. Her body has only just been found. They suspect Sherlock killed her as he wrote a signed note found in her purse, giving his address and a meeting time. The detectives disbelieve Sherlock when he says he does not know her. He was on prolific drug use then, which caused blackouts and memory loss. Maria worked at her church's soup kitchen and as a cleaner at the offices of Councilman Robert Barclay. Sherlock consults Oscar Rankin, a junkie often at the brownstone then. Oscar knew Maria as he attended the soup kitchen and had boasted of knowing Sherlock Holmes the great detective. Maria arranged a meeting with Sherlock and brought a bag containing bloodied clothes belonging to Barclay, wanting Sherlock to find out whom he had killed, for she had seen him remove the clothes, bag them, and put the bag in a dumpster, and she had retrieved the bag. Barclay had been having an affair with Kelsey Prior, the wife of a friend, but when she tried to end it he stabbed her, staging it as a robbery gone wrong, and bloodying his clothes especially his shirt. Barclay tried to retrieve the bag, it was missing, and knew Maria had taken it. He lured her from Frobisher Motel in Bayside where Sherlock often put witnesses whose lives were in danger. Barclay killed Maria and hid her body, and Sherlock, high on drugs, forgot about her. Oscar mistook the clothes for Sherlock's, assumed he wore them when he disappeared Maria while high on heroin. Oscar kept the bag in case he needed leverage against Sherlock one day, and fearing police would think he was an accomplice. Demps and McShane arrest Sherlock after a witness, Eddie Bynum, says he heard Sherlock threatening Maria just before she vanished. Joan takes the bag of clothes to the NYPD, telling Oscar they would not incriminate Sherlock but exonerate him. Sherlock recognises the shirt style as one seen being worn by Barclay in a wall photo. Traces of the killer's blood found at Prior's murder which will be checked against Barclay's. Later, Bynum and Matthew Hatano admit they lied at Barclay's behest, and Barclay confesses to both murders. Freed, Sherlock encourages Oscar to quit heroin but speaks harshly. He gives Oscar a paid reservation at Hemdale (drug rehabilitation centre) as he feels somewhat responsible for Oscar's condition. (Oscar's sequel to this story is the Season finale "A Controlled Descent".)

Galen Barrow, a driver for a ridesharing company called Zooss (Zeus), is deliberately run over and killed by a city cab. It was staged to look like professional rivalry. Barrow was an internet journalist and had begun working for Zooss recently. Gordon Meadows, a registered sex offender, admits he killed Barrow but was blackmailed after he broke his parole. Texted instructions told him to buy a retired city cab, said when, where and how to kill Barrow. Barrow's internet journalism employer, Lydia Guerrero, was having an affair with Barrow and was being blackmailed by an anonymous texter. Against her protest, Barrow insisted on hunting the blackmailer. She and Meadows have the Zooss app installed on their phones. Zooss CEO Eric Frazier orders technician Brandon Felchek to hand to the police the computer program (Olympus: Mount Olympus the home of Zeus and the ancient Greek gods) that records user details and tracks all rides. Mahra Kemp tells police her brother Patrick worked for Zooss until he was killed in a mugging a month earlier, and Barrow interviewed Mahra after Patrick's death - she suspects Barrow's death is connected. Sherlock examines Patrick's home, sees he was a sports gambler, and realises he was the blackmailer at Zooss. Sherlock reviews all Olympus data from the past week. Falchek is arrested: he had cut off Patrick's access to Olympus months before on discovering he was blackmailing users, not to protect Zooss or its users but to avoid drawing attention to his own crime, as Falchek was using Olympus to stalk Felice Armistead and broke into her home where she surprised him and he broke her cheekbone. Armistead will easily identify him. Meanwhile, Holmes is disconcerted when an Irregular makes an unusual request: "She's asked for a donation to her uterus."

Sherlock is visited by a member of Everyone, the internet activist hacker group. The visitor, username Sucking Chest Wound, explains there is civil war in the group: his faction versus prominent username Species. Then Errol White aka Species is found killed by a now-missing short samurai sword. Chest Wound's hair is found under the body, White's blood is found in his car trunk. He is arrested - real name Petros Franken. Rachel, his alibi, denies she was with Franken but later admits she lied. Sherlock reckons Franken is being framed and asks who benefits from White's death. Franken says White boasted to Everyone's 'inner sanctum' about a stash of data worth millions. Cabel Hill admits he stole the stash, but weeks before White's murder. He says the stash also contains every hack by White. From the stash Sherlock identifies Species by message style ('fist'). But there are two fists as Species was two people, a secret arrangement that allowed Species to be online longer. The surviving half of Species has a separate persona, username Tessee. Tessee killed White when he rejected Tessee's Operation Right Nut - the hack of a right-wing think tank called the Atherton Foundation. Tessee is capitalising on Everyone's sympathy for Species/White's death and the hack is imminent. The NSA says Atherton is providing services to US Intelligence. Tessee is traced as being Bradley Dietz. When Sherlock and Joan confront Dietz, he is rescued by FBI Agent Branch who says she was with him at the time of the murder. Sherlock reckons that, oddly, Branch wants Everyone to hack Atherton and, through a forensic accountant, finds that Atherton coordinates FBI and Homeland Security investigations with the internal security departments of major U.S. corporations. If Everyone hacks Atherton the group's members would be arrested for treason and Branch would gain rapid promotion. Sherlock tells Branch he knows her secret (knowingly exploiting an illegal immigrant) and will report her unless she gives the police an anonymous tip on where to find the murder weapon. Everyone has been warned about Atherton so Dietz is useless to her. Branch obeys. Dietz is arrested and confesses, and Franken is exonerated.

The body from a car rescued from a train crossing is Garrison Boyd, a debunker. His skull was bashed in by the tip of a garden gnome's hat. A cult's surveillance photos show Boyd arguing with Collin Eisley. Eisley, a wealthy real estate developer with a Picasso gracing his wall, offered to buy a beach house from Claire Renziger. She said no. Months later Boyd accused him of trying to scare her into selling, as she is hearing a ghost's voice and banging. At her house Sherlock realizes she heard Arabic and traces the source to the basement of her neighbors' empty house, where there is a freshly dug tunnel and the murder weapon (gnome). The tunnel's target is Ruby, the world's fastest transatlantic internet cable. The tunneller is identified via a local store's security video - Nadim Al-Haj. Nadim torches his apartment to destroy evidence and flees with a long thin package. Sherlock retrieves the burned remains of a box-shaped Device for analysis by TARU (NYPD's Technical Assistance Response Unit). The TARU man explains that Ruby first feeds big investment firms at 60 Hudson Street. Nadim and Eisley are linked: Nadim was Eisley's driver in Iraq, Eisley sponsored his immigration, Eisley's firm owns Nadim's apartment. Sherlock accuses Eisley of hiring Nadim to splice the Device into Ruby to steal profitable stock market data. But following prison for insider trading, the authorities monitor his transactions and his stocks are in a blind trust. TARU and Mason report the Device does nothing - data goes in and comes out without being tampered with, but Mason notes a delay of 4 milliseconds. Sherlock realises that delay is significant: investment firms with computer servers at 60 Hudson Street have an advantage as they receive data milliseconds earlier than rivals, which is plenty of time for computer transactions. Eisley's blind trust is managed by a firm whose computer servers are not at 60 Hudson Street. He hired Nadim to splice in the Device to switch the time advantage to his blind trust. After Nadim killed Boyd, Eisley paid him to stay quiet and, having no non-traceable access to money, paid with his Picasso painting (the long thin package). The Picasso has been reported as stolen, rendering it unsellable, so Nadim, when found, will make a deal with the authorities, and Eisley is encouraged to do the same. Meanwhile, police officer Hannah, daughter of Captain Gregson, asks Joan to help with a case.

A man shoots two paramedics and steals their ambulance with the patient inside. Sherlock retrieves a bullet casing which is traced to Wallace Turk. Turk admits killing the paramedics and the patient, Maggie Halpern, but refuses to say where Halpern's body is. Sherlock's examination of Turk's footwear leads to a salt marsh where Halpern's body has been eviscerated by Turk's partner. The stomach, however, was finely cut and Sherlock determines she was a drug mule but, Joan finds, an unwitting one. She had just returned from Brazil after what she thought was gastric bypass surgery. Brazilian police indicate Brazilian surgeon Dr Bruno Escanso put heroin inside her, as Escanso stole 40 pounds of medical (high-grade) heroin from his hospital and vanished. Turk is Escanso's brother-in-law. The heroin can be cut to produce more heroin of lesser grade, worth millions, but only cartels can handle such quantity. NYPD plans to question drug gang leaders. Bell and Joan visit the offices of dentist Dr Marty Ward having learned that Janko Stepovic, a drug gang leader, uses the offices since by law they cannot be bugged by the government. Ward reluctantly admits knowing Janko. Bell proposes to Janko that he aid the NYPD to thwart rival gangs. Later Janko is shot dead. Ward and his lawyer, Sarah Penley, arrive at the precinct. Ward says Janko forced his cooperation. A Chinese Triad refused to buy the heroin but stole it and cut off four of Ward's fingers to force him to give Janko's location. Ward wants immunity from prosecution, which is agreed to when he offers the location of two drug mules' bodies - at the bottom of a pond. Like Halpern they were killed, drugs retrieved, bodies eviscerated. But then their cavities were filled with rocks and sewn up to ensure the bodies sank - Halpern's disposal was incomplete. Joan notices the sutures are made of material used by dentists - Ward did it, and has tricked NYPD into agreeing immunity. He did so as with no heroin and no sale prospect, he cannot leverage Turk to keep quiet. Sherlock, Joan, Bell and Gregson trick Ward in turn, making him confess. Meanwhile, Sherlock discovers that Alfredo, his recovery sponsor, is accused of prank-stealing motor cars. Sherlock realises that he views Alfredo as a friend, intervenes, and exonerates him. As being a sponsor is incompatible with friendship, Sherlock fires him as sponsor.

Judge Dennis Vaughn is found in the Subway, fatally stabbed with a screwdriver. He was in NYC for a fundraiser for the NJ governor's re-election. He had had sex at his hotel with Loretta Nichols, one of the governor's staffers, but she has an alibi - drinks with friend Andrea Schuster. Fingerprints on the screwdriver belong to Nikki Moreno who escaped from Pemberton Women's Correctional Facility in NJ days earlier and the police hunt for her is stepped up. She had been sentenced by Vaughn. But accounts of her are contradictory: at Pemberton, a for-profit prison run by Reform Enterprises (RE), Deputy Warden Trey McCann says Moreno was a troublemaker. Later McCann is murdered with a now-missing 9mm pistol. Jeff Harper, a prisoner rights lawyer, says client Moreno had nothing against Vaughn but hated McCann, and had no reason to escape or to murder as he Harper was soon likely to get her sentence reduced. He says that Moreno was forced into an unpleasant work detail recycling computers which work exposes inmates to toxins, but Sherlock remembers Moreno's prison record stated she asked for the detail. At Pemberton Sherlock examines the recycling area, noting how easy it would have been to obtain a screwdriver with Moreno's fingerprints to fabricate evidence. He discovers her garrotted body in an outside recycling bin. Evidence shows that McCann killed Moreno, and she died before Vaughn. McCann had previously worked for CAG (Correctional Administration Group), another NJ for-profit prison. CAG executive, Perry Franklin, reluctantly lets Sherlock and Bell look at McCann's file - he was fired unofficially for corruption but officially for "excessive absences". The re-election campaign manager for the NJ governor is Schuster, Nicols' alibi, who explains what a scandal the murders are creating. Sherlock realizes the murders were intended to cause the governor to award the new prison contract not to politically embarrassing RE but to CAG. Franklin's 9mm pistol is found, with which he shot McCann, and he is arrested. Meanwhile, Sherlock discovers that Bell's girlfriend, Shauna Scott, who is a police officer in an adjacent precinct, also works, unknown to Bell, for Internal Affairs.

USDA employee Everett Keck visits Belinda's honey farm, as part of testing to learn the cause of Colony collapse disorder (CCD). Keck and her bees die from cyanide in his smoker. Sherlock believes AgriNext is behind CCD in Northeast USA. Company executive Jonah Chait denies murder, saying AgriNext had been ready to counter Keck's accusations by discrediting him - he has no relevant qualification (only a theology degree and an entomology minor), was a Buddhist seminary dropout and abused drugs. Sherlock and the NYPD visit Belinda's neighbor, Darryl Jarvis. He had filed a complaint that Keck poisoned his bee hives with deadly mites. Sherlock proves Jarvis murdered Keck, and he confesses. But Sherlock believes Jarvis' complaint. Sherlock Irregular Harlan Emple proves statistically that mites appeared wherever Keck inspected hives. Keck's supervisor, Calvin Barnes, had been investigating Keck, which ceased once Barnes became an invalid when he had a heart attack after being stung by bees. Sherlock examines the Barnes' home and concludes Barnes was forcibly injected with potassium chloride to stop his heart; the injection wound looks the same as a bee sting wound. But Keck has an alibi. Before Keck's bee-killing, CCD and academic research funding were decreasing; if CCD apparently increases, funding would rise. Sherlock and Joan meet Tara and Griffin Parker who are two married professors of agriculture organizing an apiary conference. Sherlock is surprised that Sheikh Nasser Al-Fayed, of the United Arab Emirates (UAE) royal family, will attend. He owns the world's most expensive apiary and is interested in CCD, but is a wealthy recluse. Sherlock examines Nasser's hotel room and deduces he has been kidnapped. The Parkers lured Nasser to the USA by manufacturing a rising CCD crisis through Keck and kidnapped Nasser. Evidence: winch marks on Nasser's balcony rail, hotel lobby camera footage. But NYPD then learns Nasser is on a plane home to the UAE (ransom paid) but with the UAE's denials there can be no kidnap charges. Sherlock notices that one of the flirting photos Tara sent Nasser shows her with dyed blonde hair and wearing Keck's theology academic gown. Keck's autopsy showed he had taken Viagra, and her hair is found in Keck's bed and shower. Griffin turns on his wife and crime-partner, furious at her betrayal with Keck. Tara was there when Griffin attacked Barnes. Meanwhile, Captain Gregson is offered promotion and asks Joan to research his proposed replacement.

Heroin addict Oscar Rankin (from the episode "For All You Know") kidnaps Alfredo to leverage Sherlock into finding Oscar's missing sister Olivia, a fellow drug addict. Joan and the NYPD start searching for Alfredo. Sherlock, deprived of his phone, goes with Oscar to search for Olivia, visiting his former rehabilitation center and an active heroin den, exposing him to the temptation of relapse. At the heroin den, while Oscar is sleeping, Sherlock steals an addict's phone and rings Joan, telling her Oscar's clothes have traces of the dust generated when stone is cut such as marble or granite. Sherlock finds nearby that the discarded contents of a stolen wallet contain the driving licence of Jonathan Bloom, a sexual predator who lures with heroin and believed to have killed two women. Sherlock tortures Bloom into admitting that he took Olivia but she fought him, injured him, stole his money and heroin and escaped in a taxi. The taxi driver takes Sherlock and Oscar to Olivia's destination, an abandoned railway tunnel. Sherlock finds Olivia dead of a heroin overdose. Sherlock finds Oscar's boot prints by Olivia's body. She has been dead for two days. All along Oscar knew Olivia was dead. From interior photos of Oscar's uncle's house Joan notes a jacket with a patch "South Shore Memorials", a headstone-cutting business; they head there and start searching. Oscar tells Sherlock he led him through the places Olivia had been to make him realize Sherlock is as bad as he is. It is inevitable Sherlock will use again. Oscar tosses a metal box with heroin at him and says he needs one more push. Joan texts Sherlock that they have found Alfredo alive. Sherlock beats Oscar, and picks up the box. Three days later on the brownstone roof, Sherlock stares blankly at the city. Joan, unable to get him to talk about his relapse, reports that his father will arrive the next day.

73	1	"The Past Is Parent"	John Polson	Robert Doherty	November 5, 2015 (2015-11-05)	5.58[74]
Following events of the previous episode 'A Controlled Descent', Sherlock and Joan are sacked by the NYPD, and he is nearly charged for assault. Sherlock is determined to resume sobriety. Sexual predator Jonathan Bloom asks Sherlock to find out what happened to his Honduran wife Alicia, who went missing in 2010 as, despite rumours, Bloom did not kill her. Sherlock's believes he had killed two women he lured using heroin. Now Bloom confesses, gives the location (later proved correct) of their bodies, and kills himself. Sherlock learns Alicia was friends with another Honduran, Maribel Fonseca; both vanished at the same time. Years before, Alicia, Maribel and their families were being smuggled into the USA by a 'coyote' who did not pay the drug cartel Escarra their fee for crossing their territory. The Escarra killed everyone, but Alicia and Maribel escaped. Joan visits Novena Vida in New Jersey, a restaurant both women ate at. The owner, Juan Murillo, says Maribel visited the restaurant in 2010 looking for a tall handsome man. The coyote, nicknamed El Gato (the cat), actually survived the massacre, and is described as being average height, jowly, with a receding hairline. Joan realizes this describes Murillo and that his restaurant has a cat connection as Novena Vida means "nine lives" in Spanish. Sherlock shows Murillo a video of him fighting off a robber who came to the restaurant in 2010. The video was posted online and went viral, which is how Alicia recognized him as El Gato, and Maribel went to the restaurant to check. They tried to kill him and Murillo admits killing them in self-defence. He may not be convicted for those killings, but there is an extradition treaty between the USA and Honduras, and the New Jersey police serve an arrest warrant for killing a competing Honduran coyote and his wife. Sherlock meets his father Morland who says he will fix Sherlock's mess.
74	2	"Evidence of Things Not Seen"	Ron Fortunato	Jason Tracey	November 12, 2015 (2015-11-12)	5.16[75]
Sherlock's father, Morland Holmes, offers to reinstate him and Joan at the NYPD. The next day, Sherlock and Joan begin investigating a triple homicide at a neuroeconomics research facility under the supervision of FBI agent Gary Burke, but find themselves at loose ends due to the FBI's compartmentalization of tasks during the case. Joan is skeptical of Morland's offer and Sherlock explains that dealing with him always involves a cost. Joan meets with Morland and is struck by his sincerity in supporting her partnership with Sherlock. The case is wrapped up and Sherlock takes his father's offer, but Joan discovers that Morland manipulated the DA into dropping the charges and she warns him that she will not let him hurt Sherlock. The case: At the Defense Advanced Research Projects Agency (DARPA), an experiment's test subject and the observing scientists were shot. The lab's hard drives with research and security camera footage were stolen. Sherlock and Joan meet Deputy Director Meher and Special Projects Head Alta Von See. The project was trying to perfect brainwashing. One of the victims Dr Gail Sarkisian knew the killer and let them in. Her laptop is used to frame Zheng (a member of China's U.N. mission), to show that Sarkisian knew the project was a total failure, to cast suspicion on Sarkisian's ex-husband Maurice Antonov (a reactionary monarchist), and to show Meher's extreme dissatisfaction with the project's lack of progress. Joan finds nothing incriminating on Meher but realises from media calls for him to resign that Von See would succeed him. Von See used a device developed at DARPA, called a sonic pressure shield, to incapacitate the victims then shot them. Evidence: a lab rat died at the same time as the victims, also from the shield's effects; a streak of rubber from the base of her crutch by the device's storage closet.

The woman's skeleton is found stripped and assembled as an educational tool for medical students. Meanwhile, Joan meets with an old friend and finds out that a Detective Cortez has been asking questions about her. It turns out that the victim was in a group marriage with two doctors who reveal that she was dying of pancreatic cancer. It is then revealed that one of her husbands had been deliberately misdiagnosing people because he could create impressive cancer remission rates and increase monetary profit. She noticed when she was receiving chemotherapy in his clinic and challenged him, so he murdered her. When Joan confronts Cortez, the woman voices a dislike of consultants investigating cops and is suspicious about Sherlock and Joan's sudden return to the force. Joan has a boxing match with her as a way of approaching her as an equal.

Alfredo tells Joan that Sherlock has been avoiding him. The case of a dead archaeologist presents new mysteries, as the detectives find out that he was digging up an old landfill from the 1980s. The man was searching for Nottingham Knights, an old video game from the 1980s that was never released because of monumentally bad advance reviews. Joan tells Sherlock about Alfredo, so Sherlock pays him a visit and tells him that he needs new routines to keep up his sobriety. When the video games turn up elsewhere, Joan goes searching for another lead from the landfill and finds a chemical company that was illegally dumping toxic chemicals.

A sniper shoots nine people, killing four, in the financial district and Morland visits Sherlock at the brownstone to offer his help. Although the shooting appears random, it is too precise, concealing the true target. Morland's contact in Interpol, Lukas, finds out that shooter-for-hire Gagnier was paid in a Swiss bank account by a shell subsidiary of Dynastic Energies. The CEO of Dynastic Energies, Bill Wellstone, was having an affair with his lawyer's wife, Sarah; he found out that she had left him for plumber Frank Bova, the true target of the shooting. Wellstone had used a golf bag to smuggle the sniper's weapon into the building, leaving behind gun oil residue that becomes evidence. Over dinner with Morland, Lukas voices his suspicion that Morland has not been helping Sherlock out of goodness, but rather is risking Sherlock's life. Lukas demands 5 million euros to keep his mouth shut, at which point Morland heavily implies that he had Lukas' predecessor killed for a similar transgression.

Not trusting her, Sherlock instigates further investigation, finding Underhill's blood in Mina's car. Richard Davenport confesses to Underhill's murder, but Sherlock realizes he is not the murderer but is sacrificing himself for Mina.

Sherlock speaks with a Russian spy, who says that Zolotov was supposed to be on a government mission, not business. At dinner, Morland mentions that he knows that Mycroft is alive. He also says that he has been banking his own blood and asks Joan if she will check on a blood bank in New York. The involvement of diplomatic negotiations between Russia and Ukraine causes the case to be taken over by federal agents, but Sherlock continues searching for the instigator of the shooting, with Joan asking Morland for information on arms dealers making money off the war.

Gregson is involved with a disgraced former police officer, Paige Cowan (Virginia Madsen). Page breaks off the relationship after Joan accidentally runs into them at a restaurant.

Sherlock quickly disarms the bomb and deduces that it was not Vikner, but another member of his group who wants to dethrone him by killing them, thus breaking Moriarty's rule of not harming him and Joan. The two of them find out with help from Morland that the bomber is connected to an Iranian diplomat in the organization, Hashemi, who is bent on deposing Vikner as leader. They meet with her, only to realize the enormity of the organization and to learn the reason why Morland was targeted by Vikner. Some in the organization, like Hashemi, wanted Morland as the new leader until Vikner played his hand. Sherlock, Joan and Morland work together to frame Vikner for a federal crime, only to find out that he was tipped off by a contact inside the FBI and is in the wind. Morland, in an attempt to protect his son, then contacts Vikner, who thinks he is going to be able to kill off Morland. Morland, however, has allied with Hashemi, so Vikner is killed instead by her men. Morland meets Sherlock on the brownstone's rooftop, telling him that he has taken over leadership of the organization with the aim of dismantling it from within and explaining to him that it was the only way to guarantee he would not lose his son. He also promises that the organization will not have a presence in New York and prepares to return to London.

Sherlock investigates the husband, discovering that he stands to make a fortune from a software program's invention, which manipulates video footage. The recording of the wife's kidnapping seems to use the software. Eventually the wife escapes her kidnappers but Sherlock realises she faked the kidnapping to ensure enough sympathy from her husband, who was looking into divorcing her, that he would wait to divorce her and let their pre-nuptial agreement expire. This would then net her half of his fortune (including the profits from the new video program) rather than the negligible amount under the pre-nup.

Detective Cosa thinks a Los Espectros gang member Ricky Morales was murdered by rival gang SBK (South Bronx Killas) as the body is on SBK turf. The murder weapon was an antique Japanese Nambu, now missing, and a .38 pistol was found. Two male suspects fled the scene an hour after the murder. Shinwell matches the description of one. Cosa says the .38 likely has prints on it but a lab backlog means waiting three days for the results. Shinwell flees his apartment for the brownstone, saying he was at Ricky's murder scene but did not kill him, and that he is back with SBK as an FBI confidential informant (CI). He was recruited out of prison by FBI Agent Calvin Whitlock. SBK did not kill Ricky as doing so would start a gang war. SBK sent him and Tall Boy to dispose of the body, but when the police came he abandoned the .38. Joan and Sherlock ask Whitlock to subpoena the .38 to save Shinwell being implicated so he can continue as a CI. But Whitlock refuses: due to treachery from a past CI of his he was stripped of authority to formally employ more CIs. It would ruin him to admit he used Shinwell as an off-the-books CI. Cosa has Captain Gregson put a rush on the .38 analysis and the lab results are due tomorrow. Sherlock and Shinwell find Ricky was on medication for panic attacks and regularly saw "ZX", psychiatrist Dr Zelda Xanthopoulos. ZX says Ricky's anxiety was due to being caught with cocaine and he became Whitlock's CI in return for no prosecution. Whitlock's grandfather served in the Pacific in World War II where he picked up a Nambu pistol. Whitlock killed Ricky (with the Nambu as it was not registered) as Ricky wanted to quit being a CI and threatened to expose Whitlock after working out that he had used Ricky's info to rob the gang. Several times Whitlock has used CI intel to rob gangs. His thief-partner is Lionel Trafoya, who worked with him at the FBI but resigned under a cloud. Trafoya was wounded during the last robbery. Joan tells Whitlock Cosa is interrogating Trafoya and his blood is being tested for a match at the robbery scene. Later Whitlock rings Joan from his office, summons her there, and leaves the Nambu murder weapon for her after committing suicide with it. Trafoya refuses to cooperate so Shinwell's role as a CI cannot be confirmed. Sherlock breaks into the crime lab and removes Shinwell's fingerprints from the .38 before it can be tested.

Meanwhile, Joan faces difficulty when she discovers that Shinwell is not taking his informant training seriously, opting to spend his time on a shady drug deal that could put him in the right circles within his old gang.
108	12	"Crowned Clown, Downtown Brown"	Michael Slovis	Jordan Rosenberg	January 15, 2017 (2017-01-15)	4.36[109]
Sheriff Malick (Debra Jo Rupp) at Mount Pleasant has a clown, felled fatally by a crowbar, for Sherlock to investigate, along with regular night-time sightings of clowns. The murder victim was Dale Schmitt, employed by company AdRupt that used prank-vertising to generate social media coverage. Near the murder site Sherlock and Bell find the manhole cover opened by the crowbar - it leads to NYC's reservoir of drinking water, and Sherlock realises that a dangerous substance, a newly-engineered superbug, has been added to the water. That sparks panic-buying of water, and Joan, like many citizens, installs a water filter unit at the brownstone, the only model recommended by the Department of Environmental Protection (DEP). The attacker is identified as Raymond Thorpe, a chief virologist. At his lab, his director ascertains that the substance was not fatal and would have caused mild diarrhoea only. Gio Bianchi is a suspect as his construction company had won the contract to build a water filtration plant for the city, a contract that would only be implemented if NYC's disinfection methods failed to ward off a water problem such as citywide diarrhoea. But Sherlock realises the one to gain immediately from the superbug is Wendell Hecht, VP of Water Integrity at the DEP, who owns the patent for a home water filter (put in by Joan) as each house would need one pending the years it would take to build the filtration plant. Hecht hired Thorpe to contaminate the water supply. Schmitt saw him doing it and Thorpe killed him. Meanwhile, Bell gets into a pub fight with the ex-husband of his girlfriend (an assistant DA). Joan realises it is a scheme to get the girlfriend removed from a particular case.
109	13	"Over a Barrel"	Guy Ferland	Jeffrey Paul King	January 29, 2017 (2017-01-29)	5.44[110]
Jack Brunelle, the father of a now-dead assault victim takes an entire diner hostage to force Sherlock and Joan to take his case, as they had repeatedly denied him in the years prior due to preoccupation with other cases. He gives them until midnight to find the culprit behind his son's fatal assault, as that is when the statute of limitations runs out. He certainly plans to kill one hostage - the detective who failed to catch his son's attacker. With Joan remaining behind as an additional hostage and his having mere hours before the gunman's deadline, Sherlock works with Bell to uncover what happened. They discover that the gang Shoreline 99s, on being conquered by the gang Santa Maton, switched from smuggling cocaine to smuggling maple syrup, and used a fleet of trucks and thousands of barrels for the purpose. Connor Brunelle was a security guard at the warehouse and was mugged by Shoreline 99s' strong-man Frank Trimble to stop him being on duty on the night of the transhipping. However, Sherlock makes his breakthrough after the statute of limitations apparently expires, leaving him a new challenge - how to roll back time so that Trimble can be arrested.
110	14	"Rekt in Real Life"	John Polson	Robert Hewitt Wolfe	February 19, 2017 (2017-02-19)	5.08[111]
O.G. Pwnzr, an eSports agent, is attacked while live-streaming. He was once a pro video game player. They find the body of Owen Tuchman, aka Pwnzr, in a hotel room. He was killed by a blow from a sharp tool, after being tortured for the location of Marcel Otolik aka Tendu, an Inuit from Northern Canada. Tendu works for ProFine Peripherals video game company. Tendu and a brunette woman have fled. The murder weapon is found in his room - an Inuit seal-hunting tool - but Sherlock realises he is being framed. Animal activist, Rayna Carno, and her lawyer, Gail Lundquist, are both working to ban seal-hunting. Tendu posted a social media photo of himself eating seal meat (a "sealfie") to promote seal-hunting as part of Inuit culture, and Carno replied with threats. But then Carno signed a written deal with Tendu, at which his Czech girlfriend, Libena, was present - Tendu would oppose commercial seal-hunting, Carno would support Inuit seal-hunting. Libena, and the other Czech marketing models at ProFine, are prostitutes enslaved by a Carla Petro's escort agency. For Libena's freedom, Tendu paid Petro $100,000 using money from his sponsorship deal with AmpVX. Tendu also arranged for on-going payments to his village of Maniitok in Northern Canada. Law firm Mather & Kline was hired by commercial interests to secure Inuit land to build ports on as melting ice from global warming is creating new shipping lanes. Sherlock and Bell rescue Tendu and Libena just as Kurt Godwyn, the law firm's "fixer", arrives to kill them. Godwyn's gun is proved as the one that beat Owen. Lundquist, of Mather & Kline, is arrested: she had helped Carno pressure Tendu's village to end seal-hunting to leave them destitute and thus needing to accept land purchase deals. But when Tendu's "sealfies" turned opinion against Carno, and the money he sent to Maniitok enabled the village elders to resist land purchase offers, Lundquist ordered the hit on Tendu. She tries to deny the murder but Godwyn has already confessed. Meanwhile, Shinwell asks Joan's advice about his daughter who is being harassed by a gang member.
111	15	"Wrong Side of the Road"	Jennifer Lynch	Robert Doherty and Jason Tracey	March 5, 2017 (2017-03-05)	4.26[112]
Part 1 of 2. Sherlock attends the funeral of Cy Durning. Kitty Winter (Sherlock's former protégé) surprises Sherlock there, warning that Durning did not die of a heart attack but was murdered, and that he and she are targets. In a cause celebre case she and Sherlock worked on in London, Eli Kotite, an American, committed a fatal hit-and-run while drunk, by accidentally driving on the wrong side of the road (episode's title). Kitty and Sherlock found Kotite and testified at his trial. He served nearly 4 years. Since his recent release, Kotite's defense lawyer Tom Saunders, the judge, and now Durning the prosecutor, have been killed under the guise of natural causes. Kotite was maimed in prison by resentful inmates and became wheelchair-bound, unable to commit murder directly. Sherlock visits Kotite at a private club and accuses him but he denies it. Joan reckons Durning's death was murder as a shoe lace discrepancy suggests a lethal injection between the toes. They cannot exhume the body as that night the body is dug up and incinerated, but the culprit left behind a hair strand, indicating a Caucasian who dyes his hair red. Sherlock realises he saw the red-haired henchman at the club. The M.E. who did Durning's post-mortem, Dr Wilkerson, insists on death by natural causes despite clear post-mortem photo evidence to the contrary. Kotite rings Sherlock. Sherlock warns he has uncovered the bribe to Wilkerson and will soon link him to her, but Kotite says he knows who the real killer is and asks to meet in 30 minutes. But before they can meet, Kotite is hurled from a balcony - murder thinly disguised as suicide. Durning's widow, Kate, tells Joan she saw a red-haired man outside their house as she drove away just before he died. Returning to the brownstone, Sherlock, Kitty and Watson see FBI agents and soldiers raiding it. Sherlock sends the pair to safety and enters. The man in charge of the raid is the red-haired suspect. He is Anson Gephardt, a Defense Intelligence Agency officer specialising in Middle Eastern affairs. Gephardt arrests Sherlock. Meanwhile, Joan discovers Kitty has an infant son, while Kitty and Sherlock must work out certain tensions between them.
112	16	"Fidelity"	Christine Moore	Jason Tracey and Robert Doherty	March 12, 2017 (2017-03-12)	4.50[113]
Part 2 of 2: DIA Agent Gephardt tries to convince Sherlock into ending his investigation by admitting to the murders and threatening to link him to his father's illegal activities. But Sherlock continues with the case. He deduces the murder victims had witnessed a DIA secret during Kotite's trial and were killed to silence them. Kate Durning gives Joan audio recordings that Cy secretly made of his last court hearings as material for writing a retirement book. At legal firm Farrell & Putnam, lawyer Sydney Garber reveals that employee Tom Saunders, Kotite's lawyer, was a paranoid schizophrenic prone to raving when off his meds. On a Durning tape Saunders rants at the pre-trial hearing about a 50-pound cyclonite bomb in a Venezuelan toilet. 2 days ago a bomb exploded in the bathroom of the Caracas National Library, narrowly missing the Venezuelan president. So, how did Saunders know about the toilet bomb 3 years before it happened? Sherlock concludes Gephardt is a rogue agent. He and Joan steal a document from Farrell & Putnam that proves Garber knew about the bombing before it occurred. Gephardt tries to kill Garber causing Garber to tell all to the NYPD. His college roommate, Alberto, is now the head of Venezuelan intelligence. Gephardt hired his firm to acquire the Fidel Files from Alberto - a treasure trove containing all the secret intelligence that Cuba's communist rulers, the Castros, shared with their allies. In return for the Fidel Files, Gephardt agreed to aid Venezuela by carrying out the toilet bombing when required. The bombing occurred, and sympathy votes swung an election in favour of the incumbent president, so Garber duly received the Fidel Files and gave them to Gephardt. But Garber kept a copy on a USB drive, which he gives NYPD. Gephardt uploads the Fidel Files to the internet, publicly admits illegal but "patriotic" actions to obtain them, and flees. The USA government is concerned that a video file shows Iran's nuclear weapons program is more of a threat than feared, and war now looms. On the video "kami" is overheard, a Farsi word, confirming Iranian provenance. But the video is fake as it was not on Garber's copy i.e. Gephardt secretly added it. Remembering that Gephardt's DIA specialty is Middle Eastern affairs, Sherlock realises that the partisan Gephart wants the USA to attack Iran. Gephardt is arrested at his mother's house by the FBI. There Sherlock sees a dog with the name-tag "Kammie", which sounds like the Farsi word "kami" - Gephardt faked the Iran video in his mother's basement and she is overheard on tape calling her dog. Later, Sherlock gives NSA Agent McNally, media and other intelligence agencies the materials which prove this. Kitty calls Sherlock to St Mark's Church, apologizes, and says they are not friends but family. In the church, Joan and Sherlock prepare to become Archie's godparents.
113	17	"The Ballad of Lady Frances"	Aaron Lipstadt	Bob Goodman and Jordan Rosenberg	March 19, 2017 (2017-03-19)	4.28[114]
Drywaller Darren Azoff is seized by D'Agostino and Reese Vennek. Vennek tortures Azoff by shooting him '6-pack'-style, demanding to know where the Lady Frances is. Azoff denies knowledge and Vennek shoots him dead. Audio of the incident is recorded by a device attached to a nearby telephone pole, and the live-feed heard by monitor Cosmo Dellis. NYPD assumes Frances is a kidnap victim and mounts a search. The device, by BulletPoint, is a surveillance system being piloted by NYC, designed to activate at gunshots. The scheme is a matter of political debate between the mayor and Councilman Slessinger who is running for mayor on a 'be tougher on crime' platform. Azoff's lover's house is full of goods stolen by Azoff during drywall jobs. Lady Frances, identified by photo, is the name of a vintage guitar that Azoff stole, worth $5 million as it was originally Eric Clapton's. A guitar expert points them towards Herman Wolf - Azoff had drywalled his sound studio and stolen the guitar. Wolf hired Vennek to retrieve it. Vennek went to Azoff's house but it was already gone. At the precinct Vennek betrays D'Agostino, and admits killing Azoff but denies killing the "second man" - Cosmo, beaten to death with Lady Frances. Only a guitar fragment remains, marked by the killer's blood. Cosmo had deleted the address from the BulletPoint recording so he could steal it first. BulletPoint's Thea Moser shows Bell and Joan a report she is about to submit to NYC, showing that Cosmo created fake gunshot incidents for months. Bell and Gregson invite Councilman Slessinger to admit Cosmo's murder: he got Cosmo, son of a political supporter, employed at BulletPoint to create fake incidents in districts which, once NYPD failed to solve the "crimes", would appear crime-ravaged and boost Slessinger's election campaign. He killed Cosmo with Lady Frances to cut the link to his election-rigging and destroy the guitar evidence. Beating someone while holding a guitar neck would result in cuts and Slessinger's hands show cuts that match Lady Frances' fret width. He is shown a warrant for his DNA. Meanwhile, Joan and Sherlock investigate an attempt on Shinwell's life by Damon, brother of Shinwell's friend Jameel, as Shinwell killed Jameel.
114	18	"Dead Man's Tale"	Alex Chapple	Tamara Jaron	March 26, 2017 (2017-03-26)	5.16[115]
Xavier buys the contents, sight unseen, of a storage unit whose owner failed to keep up the payments. Inside he finds valuable goods but also the owner - a corpse, stabbed by a sword. He was Travis Unger whose used his job at the Manhattan Public Administrator's Office (MPAO) to steal from people who died intestate. In one victim's MPAO crate, Bell and Sherlock find ancestor Captain Emerson Barker's 18th century chest of seafaring equipment, but missing the captain's log. Emerson's complete traders' logs are on public record but he faked them. He was a trader but also a pirate called Black Peter. The missing log forms his pirate records, including the location of sunken treasure from a raided ship called Santa Leticia. Just before he vanished Unger met marine salvager Lars Vestergaard, and offered half the treasure in return for salvaging it. Lars says he rejected the offer, as he already knew the ship's location and treasure contents from researching the Seville Archives a year ago and he obtained the salvage rights from the Admiralty Courts. But after securing investors for the salvage, someone beat him to the ship's treasure. Farhan Al-Asmari, a rival salvager, cheerfully admits taking the Santa Leticia's treasure, after buying Black Peter's log on the dark web. He displays photos of the treasure. A marine archaeologist, who once sabotaged Lars' salvage equipment, says the Seville archives show there was no treasure on the Santa Leticia. Sherlock and NYPD discover Lars oversold shares in the treasure: if any treasure was found he would owe ten times its value, but the investors' contracts stated they would gain nothing if there was no treasure. When Unger showed him Black Peter's log detailing the Santa Leticia's treasure, Lars knew he faced ruin if his salvage went ahead. He killed Unger with an antique sword from a past salvage. His ship's transponder shows where he sailed to dispose of the sword, so the NYPD know where to find it. Meanwhile, Joan and Sherlock probe Shinwell's killing of Jameel. Shinwell ambushes Sherlock and beats him. He says the SBK manipulated him into the killing.
115	19	"High Heat"	Michael Hekmat	Kelly Wheeler	April 16, 2017 (2017-04-16)[note 1][116][117]	4.29[118]
Two murder victims' remains are found illicitly burned in a crematorium. One was private investigator (PI) Fred Kirby. Numerous restraining orders served on Kirby cause Sherlock to examine a shooting spree at a courthouse in 1987: after a swearing-in ceremony a group of new citizens were shot by the husband of the group's civic teacher who then killed himself. Virginia Spivey is the widow of the bailiff who charged the gunman and heroically ended the shooting. On his death a year ago she organized a memorial displayed at the courthouse. Kirby secretly swapped the memorial's bloodstained pocket copies of the Constitution given to each new citizen, and got a lab assistant to perform secret DNA tests, seeking a paternity match to C. Gibson. Carter Gibson had a violent streak and changed his name from Carter Dunwitty as he was the son of the courthouse shooter. His mother survived the shooting and, convinced the shooter was not his biological father, Carter hired Kirby to prove it. Carter's living room is covered with blood and smashed furniture. Sherlock realised Kirby and Carter were killed by an unknown assailant. Neighbors heard a loud bang at the time of the murders. Kirby and Carter were killed by blows from a marble ball, an award Carter received for his work on the disease he was afflicted with, CMT. CMT is an hereditary condition which attacks the nervous system in the body's extremities and gets worse over time. Noticing blood spatter on a wall far from the murder, Sherlock copies the killer's movements but is unable to throw the blood as far, so the killer has an unusually strong upper arm. Houston, son of Virginia Spivey, is called to the Precinct: Carter announced evidence that he was not the son of the courthouse shooter, but it also revealed that the Spivey family had CMT. Having CMT jeopardizes Houston's career, for Houston is a college baseball star pitcher expected to gain a major league contract. The loud bang that the neighbors heard was caused by Houston who, after killing with the marble ball, threw it the remarkable distance of 245 feet with spot-on accuracy into a metal dumpster. NYPD found it there, with the blood of both victims and Houston's fingerprints on it.
116	20	"The Art of Sleights and Deception"	Ron Fortunato	Mark Hudis	April 23, 2017 (2017-04-23)	4.47[119]
Sherlock and Joan investigate when magician Claude Rysher, aka Razr, performed the bullet-catching trick but died as the bullet was poisoned. Most of Rysher's tricks were card-based and he cheated at poker, targeting Keating in particular. Keating, a banker, paid his poker debt by providing Rysher with records from 1963 of publisher Turnleaf Books. Those records were stolen from Rysher's home. Sherlock shows Joan the book "The Art of Sleights and Deceptions", the magician's bible on card tricks. It was published in 1963 under the pseudonym Walker Elmsley. Famous magician Quinn Malcolm has offered a $2M prize to whoever identifies Elmsley. A search angle is that the writer and illustrator are the same person as the drawings show the illustrator drew from a mirror. Bell, Sherlock and Joan meet with Farraday Books division head, Ballard Clifton. He says the author is Albert Lange and Clifton is his grandson and, far from the secret being more profitable, revealing it would cause a sales spike. NYPD finds that Rysher won a dark web auction to buy a rare Nazi anatomy book written by a doctor stationed at a concentration camp. Mr Frye, who lost the auction, threatened Rysher but denies killing, as he won an auction for another copy of the book soon afterwards. Sherlock examines Frye's copy and solves the case. Albert Lange illustrated the anatomy book and the magician's bible, proven by his drawing style. Clifton killed Rysher as he was about to reveal the magician's bible he had profited from for so many years was written by a war criminal, which would have ruined the company and Clifton. Clifton broke into Rysher's home - once to sabotage the magic trick and again to steal the records and research including the anatomy book. But then greedy Clifton could not resist reselling the book, even using the same description of its condition, and Frye bought that copy. Both Clifton's and Rysher's fingerprints were found on the book. Meanwhile, Bell is accused by a man called Gorham of inappropriate behaviour which, if true, would break Bell's career. Roy Booker, the ex-husband of Bell's girlfriend Chantal, is behind the bogus complaint. When Bell enters Chantal's home he finds she has been attacked.
117	21	"Flying into a Rage, Make a Bad Landing"	Guy Ferland	Bob Goodman	April 30, 2017 (2017-04-30)	4.79[120]
After Bell finds Chantal beaten and unconscious in her apartment, she is now in hospital, sedated. The attacker had also urinated on her apartment bed. Given recent problems from Chantal's ex-husband Roy Booker (in the previous episode), Bell is convinced that Booker committed the assault. Booker claims an alibi: he was surveilling a man at the Birchwood Grove Country Club for Sawyer Winthrop Rose, the law firm he works for as an investigator. He fears the NYPD will frame him for Chantal's attack, which he repeats after Bell tries to attack him at the hospital. The urine DNA is a match for Booker yet video footage from the country club supports his alibi, so someone is framing him. They find Booker shot dead in his car in a staged suicide. Sawyer Winthrop Rose specializes in finding assets hidden by divorcing spouses. Attorney Ted Winthrop, Booker's boss, points towards a Russian called Fyodor Ukhov, allegedly hiding $20M from wife Lara (Winthrop's client). Fyodor admits he saw Booker following him and slapped his car window, hence his fingerprints being at the scene. Fyodor hired his own PI, Joseph Tommolino, who gave him details on Booker and Chantal. Fyodor plans to leave for the Caymans and Bell fears he will stay there to escape justice. Bell decides to injure Fyodor to keep him in the USA, but before he can do so he sees a car-jacking thief do it - Sherlock in disguise. Bell, whom Sherlock has realised was beaten as a child by his father, knows Sherlock stopped him ruining his career. Sherlock and Joan confront Tommolino but he did not send Fyodor the Chantal/Booker intel until after the crimes. The NYPD investigate other husbands that Booker surveilled. Booker bought some herbs for a body cleanse, and has a safety deposit box containing $100,000 with a list of clients next to money amounts. Winthrop lied to his clients about how much their spouses were hiding, telling them much less and stealing the difference. Booker discovered Winthrop's scheme and forced him to pay him a cut. Learning of Booker's issues with Chantal from Booker's crooked lawyer Ardy Gulbenkian, Winthrop attacked Chantal and staged Booker's suicide. He ordered all his staff to take a drugs test (Booker used the herbs to purge his system of drugs beforehand). A lab tech confesses Winthrop paid him for a sample of Booker's urine, and Winthrop dumped it on Chantal's bed.
118	22	"Moving Targets"	Lucy Liu	Robert Hewitt Wolfe	May 7, 2017 (2017-05-07)	4.22[121]
When a small town police chief is killed while participating in a reality TV show where all the contestants "hunt" their assigned targets, the team initially suspects her current target, a former child soldier turned doctor from Africa, but soon realizes that the deceased had uncovered a complex network of police bribery and corruption. Meanwhile, Shinwell recruits Joan's help in exposing the role a member of the SBK played in another murder so that he can rise up in the ranks of the gang. He also provides her with a written confession of his earlier crimes, so that she may turn him in whenever she thinks best. Joan receives a text from Shinwell and discovers him dead in his apartment.
119	23	"Scrambled"	Christine Moore	Jason Tracey	May 14, 2017 (2017-05-14)	4.43[122]
Shinwell's body is removed from his apartment by paramedics. Joan tells Sherlock and Captain Gregson he was close to bringing down his former gang, SBK. Her anger persuades Sherlock to join her in carrying on Shinwell's work. Guzman shares his SBK files: Bonzi Folsom is SBK's leader of 13 years, rarely leaves his guarded apartment, and no one knows how he communicates with the gang. His social media feed is benign. He has a half-brother, Tyus Wilcox. Tyus is a legitimate businessman, is not in SBK, has not spoken to Bonzi in years, and the pair had a public fight. Interviewed, Tyus says he looks at Bonzi's social media to keep up with family events. Bonzi calls Bell and Sherlock to his apartment and says gang member Tall Boy killed Shinwell and gives the murder weapon's location, hoping to end NYPD's investigation. He says Shinwell was killed because Joan's details were found on his phone. Tall Boy accepts being the fall-guy. Sherlock and Joan work out how Bonzi communicates with his gang. But the NYPD fails to obtain solid evidence as the decrypted messages do not speak plainly, a drug bust based on them fails, and Bonzi deletes his social media. Bonzi's past messages include mention of people who were later murdered, people at companies that rivalled Tyus' business - the feud between Bonzi and Tyus was staged to cover that SBK was carrying out hits for Tyus. Sherlock and Joan now believe Tyus is the real leader of SBK. Tyus rejects the idea but Sherlock notices that he reacted when victim Carol Logan was mentioned. They connect Logan with Bonzi, enough for a warrant for Bonzi's DNA. But on arriving at Bonzi's apartment they find him as good as murdered (in a vegetative state coma). He had snorted cocaine that had been deliberately mixed with bleach. Throughout, Sherlock's mental processes are impaired, manifested in his mind as his mother, May.
120	24	"Hurt Me, Hurt You"	John Polson	Robert Doherty and Jeffrey Paul King	May 21, 2017 (2017-05-21)	4.11[123]
At an outdoor SBK party, gang members are planning to kill Joan when Mara Tres gang members ambush and kill them. The NYPD go on alert for a gang war. Mara Tres' leader, Julio "Halcon" Zelaya, shows Sherlock the murdered body of his sister Carmen in a crate sent to him along with a video showing her being tortured and reading out a message to Mara Tres. Nothing can stop Halcon taking revenge. Sherlock threatens to tell Halcon that Tyus is SBK's leader if the gang war is not stopped. Carmen's roommate Tanya witnessed her abduction: the kidnapper did not move like a gang member and had no tattoos. Joan can find no member of any gang devoid of tattoos. In return for immunity, Tyus provides to ADA Nelson Lewis full information on SBK. That includes every gang hit made by SBK and he admits poisoning Bonzi. He says Carmen's kidnapper and killer was Duane. But Duane has tattoos and Tyus has none, yet Lewis is not interested in prosecuting Tyus. Joan meets secretly with Halcon and says Carmen's killer is in witness protection where Halcon cannot reach him, but if Halcon gives Carmen's body to the police she can get the killer sent to prison where Mara Tres can exact revenge. Bell, Gregson and Joan show Tyus the video of Carmen. Her bloodied lip and change of restraints are because she got free at one point and bit her killer. NYPD has found Carmen's body (tip-off from Halcon). As part of his immunity deal, Tyus was required to provide a DNA sample, and this matched blood in Carmen's throat. Having lied under oath to ADA Lewis that Duane killed Carmen, his immunity deal is voided. Later, at a health clinic, Sherlock imagines his mother May with him then goes and has an MRI.

Meanwhile Sherlock's former sponsor Alfredo asks Sherlock for help robbing a car retailer who refused to pay Alfredo the 100,000 dollars that he is owed for his work. Upon further questioning, Alfredo reveals that he needs the money to give to his brother. Sherlock then refuses to help, as he knows that Alfredo's brother is the reason for Alfredo's former drug use and life of crime. Upon further discussions with Alfredo and Joan, both of them suggest that the reason Sherlock will not help Alfredo is because of unresolved feelings towards his brother (Mycroft Holmes). Sherlock then reveals that he is once again angry with his brother because the gang that wanted Mycroft dead have all since been murdered so he could come out of hiding, but he has not contacted Sherlock. Eventually Sherlock meets Alfredo and tells him he has given Alfredo's brother the money he needs, told him what he thought of him and then forgiven him, and he has decided to get in contact with Mycroft. Later, Joan finds Sherlock clearly upset in the brownstone and he reveals that he found out that Mycroft died 10 months earlier of a brain hemorrhage.
