By Joe McGinniss. A book that likely needs no introduction -- but DOES need an epilogue; this PB doesn't have the most complete one (it's a 1984 Signet 1st). That said, if you've never read this classic, it's in decent shape otherwise: spine is creased, but square, pages are toned but clean and tight, not much rubbing to the cover.
A solid reading copy, a good addition to your library of true-crime basics.
