In the canon of great conspiracy theories, the JFK assassination remains unquestionably king. The enduring national mystery has given rise to some of the most complicated explanations, and the theory offered by a new book is one of the more pleasingly convoluted, reports Vanity Fair in a look at Legacy of Secrecy: The Long Shadow of the JFK Assassination. Though to be fair, it's hard to go wrong with the book's combination of mob bosses with an attack on Cuba.
Legacy has Louisiana don Carlos Marcello taking JFK out in retribution for Bobby Kennedy's crackdown on organized crime. A super-secret CIA plan to remove Fidel Castro from office was supposed to go down a week after JFK's Dallas trip, according to Legacy's authors, and Marcello bet he could get away with the hit because J Edgar Hoover and Lyndon Johnson would rather sweep the assassination under the rug than reveal the planned Cuban plot.
