The Stranger You Know

It begins with a chilling phone call. And ends with another girl dead.
College-age girls with long red hair are being brutally murdered, posed like victims in a film noir. Each crime scene is eerily similar to the twisted fantasy of a serial offender now serving thirty years to life—a criminal brought to justice with the help of Casey Woods and her investigative team, 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….
Now the Forensic Instincts team must uncover the identity of a serial killer before his ever-tightening circle of death closes in on Casey, the ultimate target. As the stalker methodically moves in on his prey, his actions make two things clear: He knows everything about Casey. And he won't stop until she's dead.
