Recently married to James Lacey, the witty and fractious Agatha Raisin quickly finds that marriage, and love, are not all they are cracked up to be. Rather than basking in marital bliss, the newlyweds are living in separate cottages and accusing each other of infidelity. After a particularly raucous fight in the local pub, James suddenly vanishes—a bloodstain the only clue to his fate—and Agatha is the prime suspect.

Determined to clear her name and find her husband, Agatha begins her investigation. But her sleuthing is thwarted when James' suspected mistress, Melissa, is found murdered. Joined by her old friend Sir Charles, Agatha digs into Melissa's past and uncovers two ex-husbands, an angry sister, and dubious relations with bikers. Are Melissa's death and James' disappearance connected? Will Agatha reunite with her husband, or will she find herself alone once again?
