After Sir Charles Baskerville is found dead with his face twisted in stark terror, Holmes is called upon to protect his heir, Sir Henry Baskerville. Narrating the story is Holmes?s assistant, Dr. Watson, who is sent to Dartmoor while the busy Holmes remains in London. Upon his arrival, Watson learns that an escaped convict is on the loose. More unsettling events occur, including the appearance of an unknown figure on the moor.
Based on a local legend of a spectral hound that haunted Dartmoor in Devonshire, England, the story is set in the moors at Baskerville Hall and the nearby Grimpen Mire, and the action takes place mostly at night, when the terrifying hound howls for blood.
This is the third novel of the iconic detective character Sherlock Holmes. Sir Arthur Conan Doyle wrote four novels and 56 short stories featuring the fictional detective.
