"The picturesque Cotwsold village of Winter Parva has decided to warm the winter months after the holidays by roasting a pig in the town square. Agatha, always one for a good roasting, has arrived with her former protegě and current rival in the private detection racket, Toni, to enjoy the merriment. But as the rotary spit is placed over a bed of fiery charcoals and the pig is carried toward its final resting place, Agatha realizes that things are not as they seem.... "Stop!" she screams suddenly. The "pig," in fact, is Gary Beech, a policeman not exactly beloved by the good people of the village."
