The first in a series featuring Detectives Byrne and Balzano. While I liked Jessica Balzano, I had trouble with Byrne's vigilante attitude. This is not how I expect cops to behave and it dropped this from a five star rating. I thought the story itself was very suspenseful and the pace was good enough to keep me turning pages. I read this in one sitting and honestly had no idea who the killer was. It was definitely not who I thought and I was rather surprised at the ending. I will continue the series.
