Sir Arthur Conan Doyle's second collection of Sherlock Holmes short stories, first published in 1894, includes the infamous "The Final Problem"—one of the author's favorite Sherlock tales and the detective's deadliest challenge. In this ultimate thriller, Sherlock meets his match: the criminal mastermind Professor Moriarty. As Moriarty pushes Sherlock to his intellectual limits, this game of cat and mouse tests not only their wits, but also their mortality." ~Back Cover.
