When a cold case spiral resurfaces, the evidence points back to one of their own. FBI Special Agent Dirk Trainor must confront the unthinkable: is one killer learning to be two—or is something far darker linking blood, geometry, and murder?
"Self-control is the only thing that separates the hunter from the idiot."
This tense, forensic thriller blends procedural precision with psychological suspense, pulling readers into a labyrinth of adoption records, staged crime scenes, and a spiral signature that grows more perfect with every kill.
