The publication of Leslie S. Klinger's brilliant new annotations of Sir Arthur Conan Doyle's four classic Holmes novels in 2005 created a Holmes sensation. Klinger reassembles Doyle's four seminal novels in their original order, with over 1,000 notes, 350 illustrations and period photographs, and tantalizing new Sherlockian theories. Inside, readers will find: A Study in Scarlet (1887)-a tale of murder and revenge that tells of Holmes and Dr. Watson's first meeting; The Sign of Four (1889)-a chilling tale of lost treasure...and of how Watson met his wife; The Hound of the Baskervilles (1901)-hailed as the greatest mystery novel of all time; and The Valley of Fear (1914)-a fresh murder scene that leads Holmes to solve a long-forgotten mystery. Whether as a stand-alone volume or as a companion to the short stories, this classic work illuminates the timeless genius of Conan Doyle for an entirely new generation.
