A diamond is stolen from the English country estate of Lady Verinder and the renowned Sergeant Cuff is brought in from London to help solve the case. The diamond, said to bring bad luck to its owner because it was stolen from a temple in India, was given to Lady Verinder’s daughter, Rachel, on her 18th birthday. It was bequeathed to Rachel from her uncle (who stole it when he was a young soldier) on his death. The story unfolds through several narrators, all of whom know a piece of what happened. As each of them writes his or her side of the story, the reader gets just a little more information that helps to solve the mystery. You can see things invented here that were directly borrowed by future writers: Holmes’ overconfidence (and his use of London urchins as agents); Agatha Christie’s exploration of narrative reliability.
