This is a seriously great book. I love tartan noir (Rankin, MacBride, Mina,etc.) but this is one of the best I've read in a while. You should definitely read the first book(Necessary Death of Lewis Winter) before you read this. It's good, although not as good as Gunman, but it puts Gunman into context. I don't write many reviews - only books I really love or really hate. This is one I really love.
