I was listening to Sir Martin John Gilbert, who was a paid researcher for Randolph Churchill to dig up as much archival material on his father Sir Winston. Apparently, Randolph Churchill had signed a contract with Robert F Kennedy to write an official biography about his brother JFK. That Randolph Churchill had been given full access to the Kennedy archives in preparation for the book. On the same day RFK was assassinated Randolph Churchill died of a heart attack.
