Three very different women have been murdered and NYPD Detective Stephanie Chalice wants to know why. Her case begins on the Roosevelt Island tram. The conductor has been shot, but lying next to him is the real mystery: a woman who might appear to have died of natural causes if not for the handwritten note stuffed in her mouth that simply reads “Look back!” When a second woman is found dead with a rag in her mouth and another cryptic note found nearby, Chalice realizes that a psychopath is stalking Manhattan, on the prowl for a very special type of woman. Part of the murderer’s twisted game is leaving intentional clues for the police, clues designed not only to taunt, but also to do something much worse. Chalice will uncover startling truths about who she really, but will it help her to discover the killer’s real purpose before another woman dies?
