By Gerald Posner. A classic in the JFK subgenre, this one not retailing any complex/wild conspiracies but rather explicating very carefully why Oswald was the lone assassin.
A hefty first-edition hardcover in pretty good shape: some mild edgewear to the dust jacket, a few scuffs/dings to the page edges, but sits straight, pages clean and un-dog-eared. A fine reading copy (or doorstop).
