The Quiche of Death (Agatha Raisin, #1)

Putting all her eggs in one basket, Agatha Raisin gives up her successful PR firm, sells her London flat, and samples a taste of early retirement in the quiet village of Carsely. Bored, lonely and used to getting her way, she enters a local baking contest. Then her recipe for social advancement sours when Judge Cummings-Browne not only snubs her entry--but falls over poisoned dead!
