A killer on the loose in Cornwall. A PI on a desperate hunt to unmask him.

For eighteen years, private investigator Blake Hollow has been haunted by the disappearance of her childhood friend. Now, Blake has returned home to Cornwall to care for her injured mother - just as another local teenager goes missing.

Troubled by painful memories, Blake is determined to find Lucy Truscott alive. Until a chilling message leads her to the young woman's mutilated corpse on the moors.

As the police take control, Blake is convinced that Lucy isn't the killer's first victim and begins her own investigation. But as she searches for a connection between her long-missing friend and Lucy, is she wasting precious time?

Or has she uncovered a secret serial killer whose grisly intentions are about to reach terrifying new heights?

To identify the monster, Blake must confront her past and expose dangerous secrets that lurk beneath the surface of her hometown - before more young lives are taken.
