Winter Parva, a traditional Cotswolds village next door to Carsely, has decided to throw a celebratory hog roast to mark the beginning of the winter holiday festivities and Agatha Raisin has arrived with friend and rival in the sleuthing business, Toni,to enjoy the merriment. But, as the spit pig is carried towards the bed of fiery charcoal, Agatha - and the rest of the village - realise that things aren't as they seem...Very quickly it transpires that the spit pig is in fact Gary Beech, a policeman not much loved in Winter Parva. And although Agatha has every intention of leaving the affair to the police, she rapidly changes her mind when she finds out Gary's ex-wife has hired Toni to investigate. Cantankerous and competitive as Agatha is, she has to now join the fray and try and solve the case herself!
