Agatha Raisin's detective agency has become so successful that she decides to take time off for rest and relaxation. But as soon as she does, she remembers that when she does have time on her hands, she doesn't know what to do with it. So it doesn't take much for the vicar of a nearby village to persuade her to help publicise the church fete - especially when the event organiser, George Selby, turns out to be a handsome widower.

Agatha brings out the crowds for the fete all right, but there’s more going on than innocent village fun. Several of the offerings in the jam-tasting booth turn out to be poisoned, and the festive entertainment becomes the scene of two murders. Will Agatha find enough time to flirt with gorgeous George?
