chunk: Intrigued, Holmes meets with Sir Henry, newly arrived from Canada. Sir Henry has received an anonymous note, cut and pasted from newsprint, warning him away from the moors, and one of his new boots is inexplicably missing from his London hotel room. The Baskerville family is discussed: Sir Charles was the eldest of three brothers; the youngest, black sheep Rodger, is believed to have died childless in South America, while Sir Henry is the only child of the middle brother. Sir Henry plans to go to Baskerville Hall, despite the ominous warning message. Holmes and Dr. Watson follow him from Holmes's Baker Street apartment back to his hotel and notice a bearded man following him in a cab; they pursue the man, but he escapes. Mortimer tells them that Mr. Barrymore, the servant at Baskerville Hall, has a beard. Sir Henry's boot reappears, but an older one vanishes.
