By Pearl S. Buck. Yeah, I agree that it wouldn't seem at first glance, or second, to be true crime, but it literally opens with the death of Mary Jo Kopechne, so let's go with it.
A stated first from 1970 in decent fettle: some edge- and cornerwear to the jacket, a small tear to the top of the front -- but nice and bright inside, no writing or dog-ears, sits straight. A good reading copy.
