By Robert J. Groden and Harrison Edward Livingstone. "...I presume." Groden co-authored JFK: The Case for Conspiracy; this one insists the fatal shot came from the grassy knoll, that autopsy photos were forged, etc. -- although much of the photographic proof the back cover touts isn't probative to my eye.
A relatively well-kept paperback: some edgewear, very mild toning, but it sits quite straight, no writing or dog-ears inside that I can see. (You do get a podcast’s “bookmark.”) A very good reading copy.
