Sorry folks, the most recent and maybe the best I've found is THE POLITICS OF MURDER by Russo and blahblah. Check it out!
It actually caused me to momentarily doubt my own feverishly unresearched theory that surviving aliens from area 51 were contracted for the hit by Ladybird Johnson in her avatar induced desire to advance social reform using her socially awkward alien lover LBJ, progenitor of the Texas seed pod of alien dominators, distracting and eventually leading the unwitting masses to socialism and civil unrest while the alien species perfected itself and their ultimate plan to take over and destroy the world economy, diabolically inserting a Level 3 Master in the form of, that's right, George W., who not only somehow murdered JFK (in TEXAS! think about it!), but has sucessfully eliminated the financial resources to support any meaningful investigation. Alas!
In any case, despite the author's meticulous attention to names, places, dates, details and other historical facts, as well as being a compelling presentation of Cold War era politics, THE POLITICS OF MURDER would nearly succeed in closing the book, so to speak, on the Kennedy asassination, conspiracies and the presence of Skull and Bones notwithstanding.
I love you guys,
