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. She sets out to clear her name and solve the mystery of the quiche of death.

James vanishes after a blazing row with Agatha in a pub; leaving behind only a trail of blood and a dead body, everyone is left fearing the worst.
