He loved to see their faces while he was raping them. He enjoyed seeing their eyes get wide when he would pull out his knife. He fed off of their fear. It was a rush for him. In the city of Charleston, South Carolina, the skyline is dotted with countless church steeples that make up the framework of what is known as the Holy City. But in the heart of the historic district, a string of rapes and homicides has shaken the foundation of this culturally unique community. Detective Mason Stone of the Charles Towne Police Department teams up with his brothers from the FBI and state law enforcement division to take on what is proving to be the most challenging and personal case of his career. With little evidence to back their case, a task force is assembled to capture a sexual predator who seems to lurk in every corner of the city, torturing and killing young women from a local college. Knowing no bounds, the killer methodically chooses each victim with a special purpose in mind. Detective Stone is unknowingly entangled in the sadistic plan of The Watcher and is soon engaged in the fight of his life. Will Stone be able to stop The Watcher before he carries out one final-and very personal-attack?
