The Sign of Four

In 1890 Arthur Conan Doyle followed up the 1887 debut of Sherlock Holmes in A Study in Scarlet with The Sign of Four. Revealing the darker side of Holmes’s personal habits, the story introduces us to Watson’s future wife, the lovely young Mary Morstan, and plunges the now-famous detective and his companion into a case involving stolen treasure, an eerie locked-room murder, a one-legged man, the Afghan War, and a thrilling midnight chase down the Thames. An overlooked gem, The Sign of Four may be the finest of Conan Doyle’s book-length Sherlock Holmes mysteries.
