The story is set in Bangkok, Thailand ca. 2010. I was fortunate to have visited Thailand a few years ago. I found the setting to be true to my memories except for Patpong. I spent my time visiting temples, markets and an unending stream of jewelry shops with my wife. I never made it to Patpong not even for a peek.
The Queen of Patpong is an interesting read. A couple of the fight scenes are among the best I've ever read. Hallinan can write violence in a way you feel every blow.
