Anatomy of a murder - Robert Traver

At forty, Paul Biegler's world seemed to have come to an end: after ten years as DA in his small town in the Upper Peninsula of Michigan, the people had elected a new hero, a young army veteran. And Biegler had been spending a lot of time fishing and thinking about his future. Then the call came from Laura Mannion: her husband had been arrested on a charge of murder. She said that the man her husband had killed had assaulted her. Suddenly, Polly, as he is known to the entire town, sees his opportunity: maybe he can show his rival that he can defend as well as he can prosecute. What follows is one of the most brilliant courtroom dramas of all time, as Polly puts together his defence and minutely examines the seething emotions under the placid surface of his town.
