A young woman is missing. But is she in hiding . . . or has she been captured?

A dying cop asks DCI Christine Caplan to investigate a series of cold cases: bodies found in remote woods, naked and with injuries to their legs that prevent them running. As the scent grows stronger, a new victim is found in the bleak Scottish highlands, and the cold cases seem suddenly dangerously hot.

In this thrilling hunt for the missing girl, Caplan must trace where love and control get out of hand, and question where power lies in any relationship. Meanwhile, the dark nights of Scotland conceal a terrifying game of cat and mouse . . .
