The curse of the Baskervilles began in the 17th Century, when Sir Hugo swore he would give his soul to possess the beautiful daughter of a yeoman. He captured her, but she escaped. He saddled his horse and chased the girl over the moors until she dropped dead from exhaustion . . . and then a black hell-hound appeared, with eyes like fire, and ripped out Hugos throat. Now, years later, the Hound has returned. Already it has caused the death of Hugos descendant, Sir Charles Baskerville. Can Sherlock Holmes stop the curse before it claims Henry Baskerville, the heir of Sir Charles?
