A young governess, Mary Morstan, comes to Baker Street with a mystery: every year since her father vanished, an anonymous stranger has mailed her a single, perfect pearl. Now the sender wants to meet her. Sherlock Holmes and Dr. Watson follow her into a night of fog, a locked room at Pondicherry Lodge, a vanished treasure from Agra, and a breathless steam-launch chase down the Thames. Arthur Conan Doyle's 1890 novel, the second Sherlock Holmes story, is a classic tale of greed, loyalty and the meeting of Watson and the woman he will love.
