Story: Victoria Dysart has been receiving pieces of jigsaw puzzle through her door on a weekly basis. The jigsaw appears to be a picture of her tombstone. She has the subsequent pieces delivered to Holmes week by week as they arrive, until, when Victoria's brother delivers a piece, it becomes clear that there is a man standing behind the gravestone, whose identity the two final pieces will reveal. Holmes deduces from the picture that the churchyard is in Norfolk and sets out to track it down, discovering something of Victoria's father's past when he does so, having been put on the right track by Watson's discoveries about a scythe in the photo. They sit vigil in Dulwich, waiting for the delivery of the next piece. A policeman's brother, an invading tramp, and a visit to Wormwood Scrubs round off the case.

Story: A cabbie tells Holmes of a passenger wearing a yellow top hat who disappeared into his house to fetch his umbrella and never returned, leaving a suitcase in the cab. When the cabbie called at the house he was told that the man did not live there. The suitcase contains bricks and newspapers.

Some days later, Watson reads about an unhappy diner standing on his chair and haranguing the other diners at Simpson's, and the following day sees a man in a yellow top hat causing a scene feeding pigeons in Trafalgar Square. Further incidents occur over the next few weeks. Gossage visits them and tells them that his mother has been murdered by her servant girl, who has been tried and found not guilty.

Holmes believes the man is Phillimore and some time later sets Watson to follow him and insists that he must find a way to have the man arrested. The trail leads to the Lyceum Theatre where Watson enlists Stoker's help and the following day Holmes reveals the motive behind the bizarre events to Watson and Lestrade.
