The pace is excellent and it is a real page-turner, engaging and exciting. Our hero never puts a foot wrong, unlike other detectives/heroes of mystery thrillers.
One misgiving that I have is that, if you are not totally familiar with life in the United States, many references will escape the reader – that certainly happened to me (Blue Moon etc..). This is even truer if the reader does not know the city of Atlanta: there are lengthy descriptions of routes around Atlanta, various places and restaurants, all of which is meaningless to anyone outside of Atlanta.
