List of Sherlock episodes

Sherlock is a mystery crime drama television series that presents a contemporary adaptation of Sir Arthur Conan Doyle's Sherlock Holmes detective stories. It was created by Steven Moffat and Mark Gatiss and stars Benedict Cumberbatch as Sherlock Holmes and Martin Freeman as Doctor John Watson. The first series of three episodes aired in 2010, while series two aired in 2012, and a third series aired in the first quarter of 2014. A single episode aired in 2016, as a Victorian-era special, followed by a fourth series in 2017. As of 15 January 2017, 13 episodes of Sherlock have aired, including one special, concluding the fourth series. In January 2014, Moffat confirmed that a fifth series had been plotted;[1] however, as to the future of the series, Gatiss stated that due to the conflicting schedules of Cumberbatch and Freeman, a potential fifth season is still up in the air.[2] The third series has become the UK's most watched drama series since 2001,[3] and Sherlock has been sold to over 200 territories.[4]

Sherlock depicts "consulting detective" Holmes, assisting the Metropolitan Police Service, primarily Detective Inspector Greg Lestrade (Rupert Graves), in solving various crimes. Holmes is assisted by his flatmate, Dr John Watson, who has returned from military service in Afghanistan. Although the series depicts a variety of crimes and perpetrators, Holmes' conflict with his archenemy Jim Moriarty (Andrew Scott) is a recurring feature. Molly Hooper (Louise Brealey), a pathologist at Bart's Hospital occasionally assists Holmes in his cases. Other recurring roles include Una Stubbs as Mrs Hudson, Holmes and Watson's landlady; and co-creator Mark Gatiss as Sherlock's brother, Mycroft Holmes.

8.70 (UK)[8]

The police investigate a series of deaths related to people who all appear to have committed suicide by taking a poisonous pill. They turn to their unofficial consultant, Sherlock Holmes, who deduces various elements pointing to a serial killer. Meanwhile, Holmes is introduced to John Watson, a former soldier who served in Afghanistan, and the pair immediately move into a flat on Baker Street. John Watson slowly gets to know and trust Sherlock despite police officer Sally Donovan (Vinette Robinson) warning him that Holmes is a psychopath and will one day be responsible for murder. Sherlock's brother Mycroft (Mark Gatiss), at first not revealing his identity, arranges a meeting with Watson and asks whether he will spy on Sherlock for money, but John refuses. After a series of incidents, the person responsible for the deaths, a taxicab driver (Phil Davis), reveals that his victims took their own lives by playing a game of Russian roulette with two pills: one fatally poisonous, the other safe. Before Sherlock can play the cabbie's game, John shoots the cabbie from an opposite building. Before he dies, the taxicab driver reveals that "Moriarty" was his sponsor.


Loosely based on the first Sherlock Holmes novel, A Study in Scarlet.
22"The Blind Banker"Euros LynStephen Thompson1 August 2010 (2010-08-01) (UK)

7.74 (UK)[8]

Sherlock is hired by an old friend to investigate a mysterious break-in at a bank in the City. He discovers that symbols spray-painted onto an office wall are a coded message intended for an employee of the bank, who is later discovered dead in his flat. The next day, a journalist is killed and the same symbols are found nearby. Sherlock and John follow a trail of clues that link the two dead men to a Chinese smuggling ring, who are trying to retrieve a valuable item that one of the dead men stole. Sherlock eventually cracks the coded message based on Suzhou numerals and a book cipher, but not before John and his date, Sarah, are kidnapped by the criminals, who believe that John is Sherlock. Sherlock rescues them, but the leader of the gang escapes. Later, the leader of the gang is in communication with her superior, who is identified by the initial "M". She is then shot by a sniper.


Loosely based on the short story "The Adventure of the Dancing Men",[11] the storyline also incorporates elements from other Sherlock Holmes stories; the concept of coded messages, the markings on the feet of the Black Lotus members and the plot of escaping a secret society, then being tracked to and killed in England all feature in The Valley of Fear. A murder victim being found inside a locked room, accessible only by climbing, alludes to The Sign of the Four.[11]

8.66 (UK)[8]

Sherlock is commissioned by Mycroft to investigate the suspicious death of a government employee, who was working on a top-secret defence project: the Bruce-Partington Project.[12] After rejecting the case and handing it over to John, Sherlock begins to be taunted by a criminal who puts his victims into explosive vests and sets Sherlock deadlines to solve the apparently unrelated cases, which include a twenty-year-old cold case involving the shoes of a drowned boy, the disappearance of a businessman, the death of a TV personality, and the assassination of a museum security guard by the "Golem". As Sherlock solves the cases, he finds links between them. After clearing up the original case regarding the government employee, Sherlock tries to force his unseen adversary to reveal himself. Near the end of the episode, Sherlock and "Jim Moriarty" (Andrew Scott) reach a standoff, where Jim reveals that he is responsible for the crimes. In the final seconds, Sherlock Holmes points his gun at a bomb on the floor that had been strapped to John.


The episode's storyline is somewhat derived from "The Adventure of the Bruce-Partington Plans" and makes references to "The Five Orange Pips" at various points (as per the five bomb victims and electronic beeps on the phone) in addition to other works of Sir Arthur Conan Doyle.

Moriarty chooses to let Sherlock and John go after receiving a phone call. Some time later, Mycroft hires Sherlock and John to retrieve compromising photos of a minor royal, which are held on the camera phone of Irene Adler (Lara Pulver), a ruthless and brilliant dominatrix who also trades in classified information extracted from her rich and powerful clients. Sherlock obtains Adler's phone, but discovers it is booby-trapped and requires a code to disarm it. When Adler discovers that the CIA are on her trail, she disappears and is then apparently killed, only to reappear to ask John to get her camera phone back from Sherlock. Weeks later when the coast is clear, Adler tricks Sherlock into deciphering a coded message on her phone which she obtained from another well-connected client. She sends the message to Moriarty, who in turn uses it to foil a British counter-terror operation. She almost succeeds in blackmailing Mycroft, but Sherlock finally cracks the password for the phone, leaving Adler without the protection she needs to survive. The episode concludes as Mycroft tells John that she has been killed by a terrorist group in Pakistan, while in fact she was secretly rescued by Sherlock.


Based on the short story "A Scandal in Bohemia".

Sherlock and John are contacted by Henry Knight (Russell Tovey), a man traumatised by the death of his father by a monstrous hound on Dartmoor years before. Investigating Dewer's Hollow, a local spot where the beast was allegedly seen, as well as the nearby Ministry of Defence testing site Baskerville, Sherlock and John uncover a conspiracy wherein one of the Baskerville scientists, Dr. Frankland (Clive Mantle), is continuing the work of H.O.U.N.D., an aborted project to create a hallucinogenic gas for military use. Sherlock and John discover that the legendary hound is an ordinary dog used for publicity that the hallucinogenic gas makes appear as a demonic monster. The "hound" that killed Henry's father was actually Frankland wearing a red-lensed gas mask and a T-shirt bearing the logo of the H.O.U.N.D. group. Confronting both the dog and Frankland at Dewer's Hollow, John and Lestrade shoot the dog. Frankland attempts to flee, but dies when he runs into a minefield. In the final scene, Mycroft releases a confined Jim Moriarty.

Moriarty launches a simultaneous heist on the Tower of London, Bank of England, and Pentonville Prison, crimes for which he allows himself to be captured and put on trial. He secures not-guilty by intimidating the jury and visits Sherlock, explaining he still intends to "burn" him, taunting him with a "final problem" for him to solve. He also tries to destroy Sherlock's reputation. The two meet on the roof of a hospital, where Moriarty explains that assassins will kill John, Mrs. Hudson, and Lestrade if Sherlock does not commit suicide; he wants Sherlock to do this to cement his story after explaining that his "god code" was a myth. Moriarty kills himself to force Sherlock to do the same. Sherlock calls John, confesses to being a fraud, states his final "goodbye" and then steps off the roof.


Inspired by the short story "The Final Problem" and makes references to "The Greek Interpreter" (with the introduction of Mycroft Holmes at the Diogenes Club) in addition to other works of Sir Arthur Conan Doyle. The title alludes to the Reichenbach Falls, where Holmes and Moriarty supposedly fall to their deaths in the original story.

"Many Happy Returns"Jeremy Lovering[16]Mark Gatiss and Steven Moffat24 December 2013 (2013-12-24)N/A

Anderson believes that Sherlock is still alive after the Reichenbach fall. He confides in Lestrade and tells him his theory for his existence. Anderson believes a string of events ranging from Tibet to India to Germany involve Sherlock's assistance, and this is due to Sherlock not being able to stop investigating. Lestrade tells Anderson that Sherlock is definitely dead and goes to visit John, who has moved out of Baker Street following Sherlock's death. Lestrade gives John some of Sherlock's old items, including a video message from John's birthday. In the message Sherlock states that he will see John very soon and tells him to have a good birthday without him as he is 'busy'.


Broadcast online only, this mini-episode serves as a prequel to the third series and was made available on BBC iPlayer, BBC Red Button service and the BBC's YouTube channel.[14][15] It is not based on any particular story by Arthur Conan Doyle, although each of Anderson's cases refers to elements in various of the original stories, as do some other details of the episode.

Two years after his reported Reichenbach Fall demise, Sherlock, who has been cleared of all fraud charges against him, returns with Mycroft's help to a London under threat of terrorist attack. He tries to convince John—who has moved on and now has a girlfriend, Mary Morstan (Amanda Abbington)—to help; however, John is angry that Sherlock did not tell him he was alive. Instead, Sherlock enlists Molly to assist him, but when John is kidnapped by unknown assailants and is rescued by Sherlock and Mary, John returns to help find the terrorists and an underground plot to blow up the Houses of Parliament during an all-night sitting on Guy Fawkes Night.


Based on the short story "The Adventure of the Empty House",[17] and "The Lost Special" with numerous references to other works by Sir Arthur Conan Doyle, and other adaptations of the original stories.

Stolen letters lead Sherlock into conflict with Charles Augustus Magnussen, "the Napoleon of blackmail" who knows the personal weakness of every person of importance in the Western world. During the investigation Sherlock is shot and nearly killed by Mary, who is being blackmailed by Magnussen. After waking up from near-death, Sherlock escapes the hospital and lures Mary to an abandoned building, where he tricks her into revealing her false identity and attempted murder while John is listening nearby. Months later, Sherlock drugs everyone at the Holmes family Christmas party and steals Mycroft's laptop full of state secrets, and he and John take the laptop to Magnussen to trade for all of the files on 'Mary Morstan'. It is revealed that Magnussen keeps no files; it is all in his near-perfect "mind palace". To protect John, Mary, and their forthcoming child, Holmes kills Magnussen in front of Mycroft and several other witnesses, and as a result is sent off on a suicidal assignment overseas. However, he is brought back almost immediately because of a video being broadcast all over England with Jim Moriarty's face asking "Did you miss me?"


The title is based on Doyle's short story "His Last Bow", whereas the plot contains elements of two other short stories, "The Adventure of Charles Augustus Milverton" and "The Man with the Twisted Lip".

Sherlock, under the influence of drugs, enters his mind palace to solve a case from Victorian times about a bride shooting herself in the head and rising from the grave to kill her husband.

122"The Lying Detective"Nick HurranSteven Moffat8 January 2017 (2017-01-08)9.53 (UK)[8]

Sherlock is contacted by the daughter of entrepreneur Culverton Smith, who she claims has confessed to a murder, but she does not know who the victim was as her father has used a drug on her that inhibits memory. Sherlock deduces that her father is a serial killer and sets out to expose him, but he has returned to narcotics use since Mary's death and unable to clearly distinguish his own thoughts from reality. He confronts and attacks Smith, and John is forced to subdue him. While recovering in the hospital, Smith appears in Sherlock's room, confesses and then tries to kill him. John bursts in just in time to save Sherlock, who reveals that his behaviour up to that point was not just an elaborate ploy to expose Smith, but also fulfilling Mary's last wish for him to "Save John". Later John's therapist reveals that she is actually Sherlock's secret sister, Eurus, and has been using disguises to manipulate both Sherlock and Watson. The episode ends with Eurus firing a shot at John.


Title and plot elements based loosely on the Doyle short story "The Adventure of the Dying Detective".[22]
133"The Final Problem"Benjamin CaronMark Gatiss and Steven Moffat15 January 2017 (2017-01-15)9.06 (UK)[8]

Sherlock and Watson – who were shot with a tranquilliser by Eurus – trick Mycroft into acknowledging her existence. Eurus steps up her attacks on Sherlock, culminating in the bombing of his Baker Street apartment. Sherlock, Watson and Mycroft venture forth to Sherrinford, a maximum-security psychiatric facility where Eurus is housed. Although Mycroft is skeptical at the suggestion that she escaped, the trio discover that Eurus compromised the staff and controls the entire asylum. She subjects the trio to various ordeals, testing their morals by forcing them to choose which of her victims live and die and ultimately forcing Sherlock to confront the memory of "Redbeard", a childhood friend whose death set in motion events that saw Eurus incarcerated. Realising that she will continue to test him until someone he cares for dies, Sherlock tries to connect with her on an emotional level, offering the love and relationship with a brother that she never had, and Eurus stands down. Sherlock and Watson return to their apartment, and find another message from Mary imploring them to stay together. The two rebuild the flat to its original form before meeting various unusual clients.


The title matches the Doyle short story "The Final Problem",[24] but the plot contains elements from the short stories "The Adventure of the Musgrave Ritual", "The Adventure of the Three Garridebs", and "The Adventure of the Gloria Scott".[25]
