By David S. Lifton. Lifton's specific theory involves the alteration of JFK's remains between Dallas and Bethesda, and while I'm not sure he needed this many pages to get there, the good news is, you can use the book as a doorstop too. This book was a BFD in its time, considered a minor classic in the genre (but not the inspiration for the name of the Best Evidence newsletter).
This particular copy of the paperback edition is in pretty good shape: some minor shelfwear; page toning inside; a previous owner’s name on the flyleaf; a couple of crunched pages. Sits straight, though, and no other writing AFAICT. A solid reading or research copy of this sought-after tome.
