A morning jog, an unlocked door, and a furious lover add up to murder! When Dervla learns that her ex-boyfriend is wanted for knocking off his new squeeze, she snickers at his ironic fate. He's too soft to be a killer, but if he's wrongly accused, that's his own problem. Or is it? Dervla is so mad at Emil she's ready to kill him herself, but his grandmother and great-aunt reach out to her. Dervla knows that her ex is innocent. Won't she help prove it? She'll consider it. But when the nanas gift her a voodoo doll to curb her anger, she gets more than she bargained for, and so does everyone else!
