Case Closed: Lee Harvey Oswald and the Assassination of JFK

By Gerald Posner. Very well-regarded overview of the case and probably the most trustworthy argument for the "single shooter"/Oswald-acted-alone party. Extremely well blurbed and for good reason. This burly paperback is in good shape: minor shelfwear, page toning throughout. Uncracked spine, though; sits very straight, clean pages. A fine reading copy if you've never got around to it.
