Spring, 1909, and Lady Hardcastle, amateur sleuth and all-round eccentric, is enjoying a well-deserved rest. But a week after a trip to the cattle market, Spencer Caradine, a local farmer, turns up dead in the pub, face-down in his beef and mushroom pie. Once again, it is up to Lady Hardcastle and her maid, Florence, to solve the case. Armed with wit and whimsy, not to mention Florence's mean right hook, the pair set out to discover what really happened and why. Was it poison or just ill luck? As they delve further into their investigation, they encounter a theft where nothing is stolen, a seance with a troubled ghost and an ever-increasing number of Spencer's family and friends who might just have motive for murder. One thing's for sure: Lady Hardcastle has a mystery on her hands.
