Bossy, impulsive, yet hopelessly romantic, Agatha Raisin is dreading the upcoming marriage of her ex-husband, James Lacey. Although she has set her sights on a handsome and beguiling Frenchman, she can't quite stop obsessing about James. But Agatha's best intentions to move on with her life are put on hold when James's young bride is shot to death just minutes before saying "I do" and Agatha is named the prime suspect.
