Yes. Anatomy of a Murder (1958) was written by Michigan Supreme Court Justice John D. Voelker [1903-1991] under the pen name Robert Traver. Voelker based the novel on a 1952 murder case in which he was the defense attorney. The novel was adapted for the movie by screenwriter Wendell Mayes.

Those who have both seen the movie and read the book claim that the movie follows the book fairly closely, except for the finale. In the book, it is known all along that Mary Pilant [Kathryn Grant] is Barney Quill's daughter whereas, in the movie, that is revealed in the ending twist when the state attorney [George C. Scott] asks a question whose answer he does not know in advance. The character of Parnell McCarthy [Arthur O'Connell] is more delineated in the book, and the movie leaves out the cross examination of the state's psychiatrist. The cross-examiner ripped him wide open and scattered the burning pieces to the winds for daring to make a psychiatric judgment that could result in a 1st degree murder conviction without having even talked to the patient. It is said that the casting of the movie is uncannily accurate in that every face and personality in the film fits the persons in the novel. One other thing also agreed upon by mostly everyone who has both seen the movie and read the book is that the movie is superior to the read. The book's author, a Supreme Court Justice for the state of Michigan, goes deeply into the nuances of trial law, strategy and tactics, procedures, research and precedents, all fascinating stuff, but the movie is more entertaining and stylish.
