1889. The First Terror. At a boys’ prep school in the Kent marshes, a pupil is found drowned in a pond. Could this be the fulfillment of a witch’s curse from over 200 years earlier? 1890. The Second Terror. A wealthy man dies of a heart attack at his London townhouse. Was he really frightened to death by ghosts? 1894. The Third Terror. A body is discovered in the dark woods near a Surrey country manor, hideously ravaged. Is the culprit a cannibal, as the evidence suggests? These three chilling and strangely linked crimes test Sherlock Holmes’ deductive powers, and his skepticism about the supernatural, to the limit.

1894. The monstrous Hound of the Baskervilles has been dead for five years, along with its no less monstrous owner, the naturalist Jack Stapleton. Sir Henry Baskerville is living contentedly at Baskerville Hall with his new wife, Audrey, and their three-year-old son, Harry. Until, that is, Audrey's lifeless body is found on the moors, drained of blood. It would appear that some fiendish creature is once more at large on Dartmoor and, like its predecessor, has targeted the unfortunate Baskerville family. Sherlock Holmes and Dr. Watson are summoned to Sir Henry's aid, and our heroes must face a marauding beast that is the very stuff of nightmares. It seems that Stapleton may not have perished in the Great Grimpen Mire after all, as Holmes believed, and is hell-bent on revenge.
