Query: A Disappointing book

I am a Lawrence Block fan, I have all of his Matthew Scudder books in hard copy, but I had a hard time reading this book. He went into the mind of a psychopathic killer too much, where he used to let us into Matt's mind instead. A real disappointment all the way around. It's too bad too. I hope his next book is not made just for shock value as this one seemed to be.
