At home alone for the holidays, Agatha Raisin decides to host a dinner party for the elder residents in her Cotswold village of Winter Parva. Agatha's never been much of a homemaker, but she's dead set on making this the perfect holiday for the 'crumblies', as she affectionately calls them. She's decorated a tree while fending off her cats, Hodge and Boswell, and even made a (lumpy) Christmas pudding in between swigs of rum. But when Agatha dumps the pudding on the head of the local self-proclaimed lothario - an 85-year-old with a beer belly and fingers like sausages - his death by dessert proves more than a trifle as mysteries mount higher than the season's snowfall. So much for trying to do good by her neighbors. Now Agatha needs no less than a Christmas miracle to get herself out of this one.
