By Ernest Tidyman. "The True, Outrageous Story of the Plymouth Mail Robbery & How They Got Away With It," from the author of Shaft and screenwriter of The French Connection.
Apparently rather rare, this paperback looks its age -- multiply cracked spine, edgewear to the covers, page toning, and a stamp from a previous stop -- but is in fine readable condition otherwise, clean pages, no dog-ears that I can see.
