Legend has it that a phantom dog wanders around the tomb of Richard Cabel in the town Baskervilles. Conan Doyle loved the idea of creating a third novel, The Hound of the Baskervilles, in which Holmes must decipher the otherworld. Sure, there is a supernatural and terrifying air that makes a logical solution seem impossible, but Holmes cannot be deterred. In the second book of this collection, The Memoirs of Sherlock Holmes, several cases put the mental agility of the detective to test. Holmes will have to deal with his first error in judgment and with his archenemy, Professor Moriarty, who sends an assassin to kill the detective.
