In this TV tie-in edition of the classic novel, first published in The Strand in 1901, Sherlock Holmes and Dr Watson are called to the haunting and beautiful moors of Dartmoor and the home of the Baskerville family, who seem to have fallen victim to a family curse. A terrifying spectre in the shape of a great hound was once said to have hunted an ancestor across the moors and the recent, mysterious death of Sir Charles Baskerville suggests that the hound has returned. But is this really a supernatural curse or is a much more dastardly and earthly plot a foot? Sherlock and Dr Watson must solve the riddle of the hound before another murder is committed.
