Review by

A young woman appeals to Sherlock Holmes and Dr Watson for help. During the course of the investigation, the detective and his friend are called upon to solve a locked-room murder and discover the story of the disappearance of the Agra treasure from India over twenty years ago.I believe this novella was written at the start of Conan Doyle's career, and it shows: the pacing is quite uneven, and individual plot strands are quite preposterous. Still, some of the usual Sherlock Holmes trademarks are there: the bumbling police inspector out of his depth, the use of the Baker Street irregulars, Holmes's drug use and playing of the violin, Watson being used as a sounding board for the great detective's fanciful - yet inevitably accurate - ideas. This story introduces the character of Mary Morstan, who later becomes Watson's wife, but has otherwise little to say or do, apart from being the subject of Watson's immediate adoration. One for completists.
