By Joe McGinniss. Probably the author's third most widely known book, although I only read it once years ago and don't remember much. I do remember that it's a "husband claims 'carjackers' knocked him out and killed his wife" story.
The paperback has some edgewear and a small split to the back cover, and mild page toning -- but the spine is uncracked and it sits very straight. A very nice commuter copy.
