In this brand-new thriller in the Sunday Times best-selling series, Lieutenant Eve Dallas races to untangle a twisted family history while a hostage's life hangs in the balance.

Say goodnight, baby darling.

Three young women have gone missing. They're all pretty, mid-'20s- 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'.

Lt Eve Dallas and her team are brought in to investigate Lauren's murder and uncover the links to the other two women. Can they find out enough about the missing women and unmask their captor before they kill again?
