Six teens murdered. A suspect behind bars. A desperate father. In a case this shadowy, the truth is easy to hide.

Psychiatrist Dr. Gwen Moore is an expert on killers. She’s spent a decade treating California’s most depraved predators and unlocking their motives—predators much like the notorious Bloody Heart serial killer, whose latest teenage victim escaped and then identified local high school teacher Randall Thompson as his captor. The case against Thompson as the Bloody Heart Killer is damning—and closed, as far as Gwen and the media are concerned. If not for one new development…

Defense attorney Robert Kavin is a still-traumatized father whose own son fell prey to the BH Killer. Convinced of Thompson’s innocence, he steps in to represent him. Now Robert wants Gwen to interview the accused, create a psych profile of the killer and his victims, and help clear his client’s name.

As Gwen and Robert grow closer and she dives deeper into the investigation, grave questions arise. So does Gwen’s suspicion that Robert is hiding something—and that he might not be the only one with a secret.
