Sherlock Holmes is a fictional detective of the late 19th and early 20th centuries, who first appeared in publication in 1887. He is the creation of Scottish born author and physician Sir Arthur Conan Doyle. A brilliant London-based detective, Holmes is famous for his intellectual prowess, and is renowned for his skillful use of deductive reasoning (somewhat mistakenly - see inductive reasoning) and astute observation to solve difficult cases.

When Jonathan Harker visits Transylvania to help Count Dracula with the purchase of a London house, he makes a series of horrific discoveries about his client. Soon afterwards, various bizarre incidents unfold in England: an apparently unmanned ship is wrecked off the coast of Whitby, a young woman discovers strange puncture marks on her neck and the inmate of a lunatic asylum raves about the 'Master' and his imminent arrival.

Sir Charles Baskerville is dead. His body was discovered on the grounds of his Devonshire estate, face frozen in fright, not far from the footprints of a large beast. The cause of death has been determined to be a heart attack, but family legend tells another tale, and Detective Sherlock Holmes is determined to uncover the truth.

England, 1929: Mydworth - ein kleiner verschlafener Ort im ländlichen Sussex. Hier geschieht selten etwas Aufregendes ... Aber das ändert sich, als der junge Adlige Sir Harry Mortimer zusammen mit seiner amerikanischen Frau Kat in seinen Heimatort zurückkehrt. Kaum sind die beiden in Mydworth angekommen, werden bei einer Party im Herrenhaus Mydworth Manor kostbare Juwelen gestohlen. Die beiden Täter kann man auf frischer Tat ertappen: einer wird erschossen, aber der andere kann fliehen.

"The Return of Sherlock Holmes" is a collection of 13 Sherlock Holmes stories, originally published in 1903-1904, by Arthur Conan Doyle. This was the first Holmes collection since 1893, when Holmes had "died" in "The Final Problem". Having published "The Hound of the Baskervilles" in 1901-1902 (although setting it before Holmes' death) Doyle came under intense pressure to revive his famous character. The first story is set in 1894 and has Holmes returning in London and explaining the period from 1891-94, a period called "The Great Hiatus" by Sherlockian enthusiasts.
