Look Behind You: An edge-of-your-seat serial killer thriller with a heart-stopping twist (Detectives Kane and Alton)

Fear grips her as the heavy footsteps echo along the isolated trail path. She thought she was alone in the woods, but as a hand reaches out from the darkness to cover her mouth, she knows that nobody will hear her scream... When Jan Pierce is reported missing, Sheriff Jenna Alton and her deputy David Kane rush to the forest surrounding Black Rock Falls. Jenna's heart breaks when she sees Jan's body at the bottom of a ravine. But it's the purplish bruising in the shape of a boot on her back that tells Jenna it was no accident. Somebody killed her. As Jenna investigates Jan's last movements, she learns that Jan joined a self-defense class and told her closest friends that she thought someone had followed her home one night. Was someone watching her every move, waiting for the right moment to strike? Then another woman from the same group, Sierra Lang, is reported missing. When Jenna finds Sierra at home, her lifeless body submerged in bathwater amid clear signs of a struggle, she is certain there is a serial killer in town. With no sign of forced entry, Jenna believes Sierra knew the killer and let him in.
