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.
Pity this seldom-seen paperback isn't in better shape -- cracked and leaning spine, toned and worn pages, an envelope flap stuck in the flyleaf (yeah, idk), nicks and creases to the covers. But it's a bit hard to find, and this copy, while frumpy, will get the job done.
