Arthur Conan Doyle's The Sign of Four is the second novel in the Sherlock Holmes series, following the enormously successful novel A Study In Scarlet. With the mysterious disappearance of a British Indian army officer, a one-legged hooligan, a stolen treasure, and a nefarious pact between four con-men, this novel of revenge and love is an exquisite classic of crime fiction.

In the infamous opening of the novel, Dr. Watson finds Sherlock Holmes in his Baker Street home, bored and in the process of taking cocaine. Dr. Watson finally confronts his friend, and Holmes retorts that he does not do well in moments of tedium; luckily the doldrums are evaporated with the arrival of a beautiful woman at the door of Baker Street; she is Mary Morstan, a character that Sherlock Holmes fans are very acquainted with as she eventually becomes the wife of Dr. Watson. Mary asked for the help in a very strange case; years ago her father disappeared from his post in India as an army officer, a few years later she began receiving an exquisite pearl in the mail on an annual basis for the past six years. Mary revealed a letter to Holmes from the sender of the pearls, asking to meet in person for clues to her father's disappearance and the motive behind the pearls. When they meet Thaddeus Sholto, Holmes and Watson are snarled into a web of a dangerous hunt and a morass of intrigue including a secret Indian treasure, four ex-cons, a one-legged gangster. The Sign of the Four, one of the most popular of the Sherlock Holmes crime novels, has been adapted into numerous film and TV productions.
