The Hound of the Baskervilles (1959 movie)
Dr. Richard Mortimer recounts to Sherlock Holmes and Doctor Watson the legend of the ghost hound that killed the devilish Sir Hugo Baskerville for his murder of the daughter of a servant. He asks Holmes to investigate the death of his friend Sir Charles Baskerville, in Dartmoor, from heart failure, lying in the moor surrounding his estate, Baskerville Hall, with a look of horror on his face. Mortimer fears for the life of Sir Henry, who's just come from South Africa to take possession of his inheritance and of Baskerville Hall.
