The woman’s body was found in the early morning, on a bench in a New York City playground. The fatal wound was hidden beneath a ribbon around her neck. And the note: Bad Mommy, written in crayon as if by a child. Eve Dallas turns to the department’s top profiler, who confirms what seems obvious to Eve: They’re dealing with a killer whose childhood involved some sort of trauma --- a situation Eve is all too familiar with herself. Yet the clues suggest a perpetrator who’d be roughly 60 years old, and there are no records of old crimes with a similar MO. When Eve discovers that other young women --- who physically resemble the first victim --- have vanished, the clock starts ticking louder.
