When Sir Charles Baskerville dies suddenly from a heart attack, a rumour of a deadly, supernatural giant dog, who may have been persecuted for generations, begins to circulate in the village. When Sir Henry Baskerville arrives from Canada for the legacy of the Baskerville manor in England, the skeptical Sherlock Holmes is called to help with the case. Was the death of Sir Charles Baskerville really a heart attack or maybe an animal lurking in deserted moors? Will Baskerville's new owner become the next victim of the dog? The Hound of the Baskervilles is Sir Arthur Conan Doyle's third Sherlock Holmes novel. The Hound of the Baskervilles is one of Doyle's most famous works and has been adapted for the big screen more than 20 times.
