The Sign of the Four
The Complete 1890 Text of The Sign of Four, with Eighteen Original Illustrations
Sir Arthur Conan Doyle
A locked room at the top of a house, a man dead in his chair with a thorn behind his ear, and a scrap of paper bearing the sign of four. Mary Morstan has been sent one enormous pearl a year for six years, and Holmes’s second case ends in a steam-launch chase down the Thames. Eighteen original illustrations.
