On the fog-drenched moors of Devonshire, Sir Charles Baskerville is found dead. The locals whisper of a monstrous hound. Holmes, naturally, is sceptical. The moors, however, are not finished yet. When Sir Henry Baskerville arrives from America to claim his inheritance, Holmes and Watson descend upon Devonshire to untangle a mystery that is equal parts murder, folklore, and something far darker than either man bargained for. The curse on the Baskerville family is ancient, the moors are unforgiving, and the fog hides more than it reveals.
