Edited by Art Crockett. "From the files of True Detective Magazine." Melodramatic cover subhed (and artwork) aside, I do appreciate that they were distinguishing between spree and serial killers even 30 years ago.
If you would like to "read and beware" as exhorted by the flyleaf, here's what to know: the paperback is evidently previously owned -- edgewear, a cracked spine with a sticker on it -- but sturdy and fairly square. A sight cheaper than collecting the original mags.
