Sherlock Holmes made his first appearance in the novel « A Study in Scarlet » written by the author Sir Arthur Conan Doyle and appeared in 1887.
The character of Sherlock Holmes still gives nowadays an iconic interest in the genre of English literature, thanks to his tactical sense and his logical reasoning that makes him unique in its kind.
