The Hound of the Baskervilles, published in 1901, is one of the Sherlock Holmes mysteries written by Arthur Conan Doyle. It is a Gothic-style mystery, with two dead bodies at the hands of a possibly supernatural beast. The famous detective Sherlock Holmes and his sidekick, Dr. Watson, are venerated for their powers of observation. The passage is taken from Chapter 14, the denouement of the novel, in which all the evidence provides the final answer. Sir Henry, used as the bait, is heir to the estate that is used as the setting, and he is the heir to the ancient family curse of the hound. The man on the moor is the murderer, and Lestrade is a Scotland Yard inspector who has come to help Holmes. Answer the questions on the basis of what is stated or implied in the passage.
