Dark Tales Hound Baskervilles

"Sir Charles Baskerville, master of the Baskerville estate, is found dead at the gates with a look of horror on his face. A family curse, the footprints of a giant hound, an escaped convict, and a stolen shoe bring Sherlock Holmes and Dr. Watson to Dartmoor to investigate the death of Sir Charles and guard the heir, Henry Baskerville, against foul play. Is the supernatural at work on the moors, or is there a rational explanation?"
