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. With an Afterword by David Stuart Davies, a Fellow of the Royal Literary Fund, and an authority on Sherlock Holmes. He has written the Afterwords for all the Collector’s Library Holmes volumes.
