In the small village of Carsely, there is great joy: Agatha Raisin has finally married James Lacey! But soon dark clouds gather over their marriage, and the newlyweds start avoiding each other. Agatha even accuses James of having an affair. When an ugly argument breaks out in the pub over this, events take a dramatic turn: first, James disappears, leaving nothing but a huge bloodstain, and then his alleged mistress is murdered. The police primarily suspect one person: the domineering and quarrelsome wife - Agatha Raisin.
