Richard Cross vividly remembers the assassination of US President John F. Kennedy on November 22, 1963. As a Security Officer for the CIA, it had been his assignment two years previously to protect his President, and he clearly understood with his head as well as his heart what a world-shaking event this would turn out to be. Always curious about the many conspiracy theories that began swirling around almost immediately, Cross used the springboard of the Warren Commission's release in 2013 of papers that had been sealed for 50 years to focus his investigative skills on finding the real reason Lee Harvey Oswald killed John F. Kennedy. Was he a KGB agent? Mostly likely. Was he following orders from the KGB? Less likely; in fact, Cross surmises, Oswald was a rogue agent, following his own inner impulses, against the wishes of the Soviets. Cross puts heart as well as his head into this fascinating, thorough treatise.
