The Return of Sherlock Holmes

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 Adventure of 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.

This collection contains stories set from 1894, giving Holmes the period from 1891-94 to explain - "The Great Hiatus" has been the subject of intense speculation and analysis by Sherlockian enthusiasts.

Also of note is Watson's statement at the end of the cycle that Holmes has retired, and forbids him to publish any more stories. - from Wikipedia
