Could the enormous ghostly dog that is claimed to have followed Sir Charles Baskerville's family for generations be to blame for his untimely demise? Sherlock Holmes, the archetypal rationalist, condemns the theory as absurd. He also sends Watson to Devon while he is preoccupied with another case to watch the nearby suspects and watch out for the Baskerville heir. The Hound of the Baskervilles is one of the best crime stories ever written, with its savage apparition and dramatic setting on the ancient, untamed moorland. In order to beat an opponent who is nearly equal to him, Sherlock Holmes must choose between reason and magic, good and evil.
