Sir Arthur Conan Doyle

"The Abominable Bride" is a special episode of the British television programme Sherlock. The episode was broadcast on BBC One and BBC One HD on 1 January 2016. It depicts the characters of the show in an alternative timeline; in the Victorian London setting of the original stories by Arthur Conan Doyle. The title is based on the quote ("Ricoletti of the club foot and his abominable wife") from "The Adventure of the Musgrave Ritual", which refers to a case mentioned by Holmes.

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. Based on the novel The Hound of the Baskervilles.

The police investigate the deaths of a series of 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 in 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, kidnaps Watson and asks whether he'll 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. Watson shoots the cabbie and runs away. As he dies, the taxicab driver reveals that Moriarty was his sponsor.

C. Auguste Dupin is a character created by [Edgar Allan Poe] whose first appearance in [The Murders in the Rue Morgue] is considered to be the first ficticious detective story.

Brigadier Gerard is the hero of a series of comic short stories by the British writer Arthur Conan Doyle. The hero, Etienne Gerard, is a Hussar in the French Army during the Napoleonic Wars. Gerard's most notable attribute is his vanity - he is utterly convinced that he is the bravest soldier, greatest swordsman, most accomplished horseman and most gallant lover in all France. Gerard is not entirely wrong, since he displays notable bravery on many occasions, but his self-satisfaction undercuts this quite often. Obsessed with honour and glory, he is always ready with a stirring speech or a gallant remark to a lady.

The Narrative of John Smith (2011) is a novel written in 1883 by Arthur Conan Doyle, published posthumously by The British Library. In a work of narrative fiction, Doyle writes from the perspective of a middle-aged bachelor named John Smith recovering from rheumatic gout. Unlike his later work in detective fiction, fantasy, and science fiction, this novel unfolds through a series of tangential, essay-like thoughts stemming from observations on everyday life.
