A bloodied and bruised girl runs out of the woods and into the path of oncoming traffic. The police are shocked to discover that she's a missing schoolgirl they've been trying to find for the past three weeks. Traumatized by her ordeal, she's unable to tell them what happened to her.
A woman's body is found crucified in a barn on the Yorkshire Moors. Evidence found at the crime scene links her to the schoolgirl.
Hot on the heels of a commendation for her work on a serial killer case, Detective Inspector Danica Summers is invited to join an elite task force specializing in the investigation of high-profile crimes. Concerned that she's only been invited because she's good PR, Dani is desperate to prove that she's worthy of her place on the team.
When the case involving the missing schoolgirl and the murdered woman is taken on by the newly-formed Murder Force, Dani is touched by the vulnerability of the victims and is determined to capture the monster who ruined their lives.
Her search for justice will take her to the heart of darkness.
