By Bill Minutaglio and Steven L. Davis. About an underreported bank heist! ...No, of course it's about the murder of President Kennedy, but really more broadly about Dallas in the early '60s (it's listed under History/Political Science).
It's also an award-winner, and in terms of its condition, "award-winner" is a little strong, but it's a lovely paperback with a very slight spine lean from shelf storage -- otherwise in excellent shape and a fantastic reading copy.
