By Albert DeSalvo and George William Rae. "Official tape-recorded" confessions, no less; "an incredible picture of a sick mind and of the horrifying crimes it conceived." If you believe DeSalvo did it, that is.
A creepily designed 1967 paperback that looks its age -- page toning, edgewear, crunched pages, a cracked spine with a weak center hinge -- but most pages are fairly firm and the book sits straight.
