Five victims, bonded by blood. A detective blinded by revenge.

Jake Sawyer is suffering. After a bruising confrontation with a cruel killer, he has isolated himself in a remote cottage in the bleak and beautiful northern Peak District.

Facing an uncertain future, he resumes his covert investigation into his mother’s murder, and enters therapy to explore his lack of primal fear response.

When an ex-TV personality is found murdered, from a single stab wound to the heart, Sawyer suspects a ritualistic element. But then a second victim is found, and he forms a terrifying theory about the killer’s twisted logic.

As Sawyer edges closer to mental collapse, he must protect the killer’s targets as he uncovers the truth behind the death of his mother.

A truth that will put his reputation, and freedom, at risk.
