By Edward Keyes. "The terrifyingly true story of the savage co-ed killings -- by the boy who could have lived next door!" ...Not sure what that means; I can tell you the late Keyes, who co-wrote The French Connection, won a fact-crime Edgar for this account of the Ypsilanti Ripper case.
This PB is in visibly used shape — edgewear; some page toning — but the pages are snug, and it sits pretty straight, uncracked spine and clean inside AFAICT. A good reading copy.
