Pretty Maids All In A Row
Six dead women in a hotel room. Five of them students, still in their teens. Tied up. Tortured. The NYPD recognizes the suspect's signature -- three bloody initials carved into each victim's forehead. Ex-cop Frank Quinn has faced this madman before. Both bear scars from their last encounter. Killer and cop, hunter and prey... In a deadly game of matched wits, only one can prevail. It's not just about who gets killed. It's about who will survive...
