How a Gunman Says Goodbye - Malcolm Mackay

He read

This is the second book in a trilogy; he read the third one first and really liked it.  Focused on an aging killer and the rise of a new, young killer in a crime organization, this was not as interesting as the third one was.  The character development in the third was excellent, this one not as much.  The author has a good grasp of the underworld in Glasgow.
