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.
