The Cotwsold village of Winter Parva has decided to roast a pig in the town square. Agatha has arrived with her current rival in the private detection racket, Toni, to enjoy the merriment. But as the pig is carried toward its final resting place, Agatha realizes that things are not as they seem, the pig, in fact, is Gary Beech, a policeman not exactly beloved by the good people of the village. Although Agatha has every intention of leaving matters to the police, everything changes when Gary's ex-wife hires Toni to investigate.
