The third Sherlock Holmes book by Arthur Conan Doyle was titled The Hound of the Baskervilles.

A long-standing rumor on Dartmoor about a curse that runs in the Baskerville family is being looked into by Sherlock Holmes and Dr. James Mortimer. According to the legend, a demonic hound that had previously killed one of their ancestors has been stalking the bogs ever since.

Dr. Mortimer worries about the heir to the estate, but Holmes offers to assist him in locating the myth's origin.In order to meet the estate's owner, Sir Henry Mortimer, Holmes, Watson, and Mortimer travel to Baskerville Hall in Dartmoor.

Henry is being stalked as he walks down the street, so Holmes asks Watson to accompany him so that he would be safe.

The first night is filled with mysterious occurrences that keep Sir Henry and Watson awake; it is only during the day that they can relax while exploring the neighborhood and meet a few people.

Continually searching for information that might help identify the person who is stalking Sir Henry, Watson constantly updates Holmes on his findings.By having Sir Henry accept an invitation to Stapleton's home and walk back after dark, allowing his opponent every chance to unleash the hound on him, Holmes decides to use Baskerville as bait to catch Stapleton unprepared.
