By Lowell Cauffiel. I haven't read this one, and based on the back cover's descriptions of the crimes therein, I'm...probably all set, as Eddie Lee Sexton was a monster. Cauffiel's writing is evidently effective, though, as this one's blurbed by Ann Rule on the front cover, and Elmore Leonard on the flyleaf.
The paperback has visible edgewear, especially along the top front and spine, and the spine is cracked, but it's very straight, and while the picture pages aren't the most secure, this one's fine as a reading copy.
