When a good guy needs to team up with a serial killer to find answers, Then I know that I am in for an edge of my seat read. The description drew me in. How bad a guy could the bad guy be? Obviously very bad if we need the mind of another criminal. Especially if we need the contacts of a bad guy. Prisons are very protected and the thought that an officer started shooting away leads me to believe that the prison is involved. However as these two unlikely "detectives" work together I was tossed back and forth between who was guilty. This is an edge of your seat read. I was mad when my hubby kept trying to interrupt me while I was reading. It really reminded me of a crime thriller tv-show. As a fan of Stephen King I loved the author's way of describing the bloody scenes. I liked this book a lot, and will be on my have to read author list. The end also left me wanting for more from this author. I am giving this book a 5/5. I was given a copy, all opinions are my own.
