Agatha Raisin, a public relations professional, gives up her life in London in the hope of starting a new life in the seemingly quiet village of Carsley, but soon finds herself a suspect in a murder case when she enters the village's annual quiche-making competition in an attempt to ingratiate herself with the community.
