Four of a KindPaperback, 6 March 2018

When a girl in the New England town of Ryme is found brutally murdered, the community seeks help from criminal psychologist Audrey Harte.

The media wants Audrey's insight into the mind of a killer, and the school and parents hope she can help the students properly process the crime.

But Audrey can't resist assisting Detective Neve Graham in the quest to find the killer. A killer who seems willing do anything to avoid going to jail, even killing a cop -- or a psychologist.
