By Ryan Green. “A True Story of Betrayal, Brutality and Butchery” featuring “the first real ‘superstar criminal’” Earle Nelson. The author seems to specialize in particularly grim cases, and this PB does have a content warning on the back…unusual for the genre.
A visibly pre-owned paperback — edgewear and a couple of cover creases; the covers “fly out” — but it’s clean inside; a decent reading copy, contents notwithstanding.
