The Hound of the Baskervilles is one of Doyle's best-known Holmes novels, frequently adapted for film and television, which is not surprising given the highly dramatic scenes of mist-wrapped moors echoing to the horrific howls of a supernatural hound. Is this a genuinely devilish apparition or is there a cunning murderer at work? Only Sherlock Holmes can solve the mystery. This volume also contains The Valley of Fear, a dark, powerful tale in which Holmes confronts the evil Professor Moriarty once more.
