By Larry Tye. The jacket copy of this bio from the author of Satchel claims that RFK Sr. is the "most complex and controversial" member of the clan. Pretty sure his namesake has him beat on that second thing, but in any event, while this is more a straight history than true crime, you...kind of can't argue with the ending qualifying it in the genre.
The hardcover is in quite nice shape -- some edge- and corner-wear to the jacket, but clean bright pages, and the book sits square. A fine reading copy for the price.
