Three young women have gone missing. They’re all pretty, mid-twenties – someone clearly has a type. But no one links their disappearances until the first – Lauren Elder – is found lying peacefully on a bench in a children’s playground. She is neatly dressed with a wide black velvet ribbon covering where her neck has been precisely slit. Her hands are folded over a childish sign on which is written in black crayon – BAD MOMMY. Lieutenant Eve Dallas races to untangle the twisted mystery.
