Any book cover with NYC catches my attention! I was instantly curious to know more about Peter and what happened to him. I currently live in that area and never knew of this story, so that made me want to know even more. The author gives incredible details that are both enticing(he answers all the curious questions that I would ask) and kind of annoying, ( too much unnecessary information that sometimes makes me forget for a second where this was going) But that's not enough to stop me from wanting more! I want/ need to know what they know about the killings and the killer. And why haven't they solved these cases! I am completely enthralled!
