Why it matters
The industrial method is outrageous; the Plummer family's resentments are pure classic mystery.
A family business gives Midsomer a productive alternative to a village club: relatives also have jobs, loyalties and competing ideas about ownership. The threatened takeover of a relish factory makes those tensions concrete. Choose this if you enjoy a familiar local institution becoming a battlefield between commercial ambition and family identity. The unusual industrial setting adds flavour, but the relationships keep the premise understandable.
Watch for
Listen for the difference between caring about the company’s future and caring about one’s own place in it.
Before you choose
The food-business setting does not make this a gentle culinary mystery; keep the crime details for the episode itself.
Casebook editorial interpretation. Distributor synopsis · factory and takeover premise ↗
Dexter Lockwood's body is discovered in the famous Plummer & Son relish factory after he joined a public tour. The family initially treats him as an anonymous visitor, but Barnaby and Scott establish that Dexter was known to the Plummers and had arrived with a purpose.
Legal documents, disputed inheritance and reported sightings place the factory's past beside its uncertain future. The celebrated recipe matters commercially, yet the harder secret concerns what happened inside the family long before the tour machinery started.

Who was the killer in Sauce for the Goose? (spoiler)
