By Harold Schechter. I always forget Schechter is (as of this writing, anyway) an emeritus professor; it's historically been easy to dismiss his work as mass-market garbage because the early stuff was focused on ghoulish cases -- like this one, his second, about Ed Gein. This one isn't great on the prose level but Schechter does the work.
This paperback is in decent shape: some edgewear, cornerwear, faintly cracked spine; writing on cover (sorry that price isn't accurate ;) ) and previous owner's notes on flyleaf; page toning. But it sits straight; a fine reading copy. (Contents aside.)
