My husband, two sons and I have all read all of James Lee Burke's Dave Robicheaux novels. We all believe that he is one of the best living American writers. The first Robicheaux book was Neon Rain. The most recent was The Tin Roof Blowdown about the aftermath of Hurricane Katrina. I think it's his best yet. I think that Robicheaux was originally with the NO police department, and went back to New Iberia after some problems there as well as his own alcoholism.
I bet you can find them all in the library.
