It begins with a chilling phone call to Casey Woods. And ends with another girl dead.

College-age girls with long red hair. Brutally murdered, they're posed like victims in a film noir. Each crime scene is eerily similar to the twisted fantasy of a serial killer now serving thirty years to life—a criminal brought to justice with the help of Forensic Instincts.

Call. Kill. Repeat. But the similarities are more than one psychopath's desire to outdo another. As more red-haired victims are added to the body count, it becomes clear that each one has been chosen because of a unique connection to Casey—a connection that grows closer and closer to her.

Now the Forensic Instincts team must race to uncover the identity of the killer before his ever-tightening circle of death closes in on Casey as the ultimate target. As the stalker methodically moves in on his prey, his actions make one thing clear: he knows everything about Casey. And Casey realizes that this psychopath won't stop until he makes sure she's dead.
