'Who knows, Watson? Woman's heart and mind are insoluble puzzles to the male. Murder might be condoned or explained, and yet some smaller offence might rankle.' The Case-book of Sherlock Holmes is a collection of Sir Arthur Conan Doyle's last twelve stories about the adventures of consulting detective Sherlock Holmes and his biographer Dr John Watson. With unforgettable tales like 'The Adventure of the Sussex Vampire', 'The Problem of Thor Bridge' and 'The Adventure of the Lion's Mane', Doyle reveals darker themes, higher stakes, twisted characters and a look into the minds of one of the most well-known detectives ever created.
