In what is arguably both the best Sherlock Holmes story in the canon and one of the classic all-time mystery novels, Sir Arthur Conan Doyle parlays his interest in the occult with keen scientific detection in a story that prominently showcases Dr. Watson. A lonely English moor, full of ancient woe and inhabited by a hound from hell, and a host of suspects all give Sherlock Holmes and Watson a baffling case to solve.
