James Jesus Angleton, the legendary counterintelligence chief of the CIA, pointed out to me that an apparent suicide could be a disguised murder especially of the victims held secrets of interest to intelligence services. In this light, I investigate four apparent suicides of men who held secrets. *** The jailhouse death of financier Jeffrey Epstein in New York*** The strangling of oligarch Boris Berezovsky in England*** The hanging of "God's banker: Roberto Calvi in London*** The shooting of CIA executive William Paisley in Chesapeake Bay*** The death of George de Mohrenschildt in Florida
