From Lloyd Devereux Richards comes the next pulse-pounding thriller in which FBI agent Christine Prusik races to track down a serial killer who leaves a peculiar mark on his victims.

Forensic anthropologist Christine Prusik has a knack for solving the most unusual cases – and for bending the rules in the process.

When the bodies of young women start appearing in the caves of Indiana and Illinois, Christine immediately jumps into action.

But her Chicago field office is undergoing a reorganization, and the boys’ club at the top seem more interested in getting all the paperwork in order than solving the murders.

Christine isn’t going to let a little red tape stop her, and when she discovers that all the bodies contain the same mysterious pin-sized bruise on the back of their necks, she realizes she’ll have to confront her own inner demons to find the killer.

Lloyd Devereux Richards was born in New York City and travelled extensively in Europe, Africa, and Central America before attending law school.
