I always liked
Midnight in the Garden of Good and Evil. It is quirky, it is true crime, but also a portrait of Savannah in the 1970s and 1980s as a character.
I also enjoyed
Honor Killing: Race, Rape, and Clarence Darrow's Spectacular Last Case (
http://www.amazon.com/Honor-Killing-Clarence-Darrows-Spectacular/dp/0143036637/ref=sr_1_12?ie=UTF8&qid=1311347175&sr=8-12). The book looks at events surrounding a case where Darrow ended up defending a group of people who had killed a young Hawaiian man accused (probably falsely) of raping a navy wife and socialite. Its an odd turn for Darrow who had done cases that went against what these people had done, but he had been wiped out in the crash of 1929 and desperately needed the money.
