The monstrous Hound of the Baskervilles has been dead for five years, along with its owner, Jack Stapleton. Sir Henry Baskerville is living contentedly with his new wife Audrey and their three-year-old son Harry—until Audrey's lifeless body is found on the moors, drained of blood. It would appear some fiendish creature is once more at large on Dartmoor and has targeted the Baskerville family. In James Lovegrove's continuation of the classic tales, Sherlock Holmes and Dr. Watson must face a marauding beast, and it seems that a vengeful Stapleton may not have perished after all.
