Detectives Sloan and Crosby investigate a fatal inheritance settlement in the twenty-fifth instalment of this popular cozy mystery series Four strangers arrive at the solicitors' office of Puckle, Puckle, and Nunnery. They have never met, and have no idea why they have been invited. But they - along with a missing man - are descendants of the late Algernon George Culver Mayton, the inventor of 'Mayton's Marvellous Mixture' and each entitled to a portion of the Mayton Fortune. But before they can split the money, the missing man must be found. Two months later, Detectives Sloan and Crosby receive a call that one of the legatees has died following an attack of food poisoning. Did the deceased merely ingest a noxious substance by accident, or are the legatees being picked off one-by-one?
