The freemasons ? I've read a few possibilities which includes Jacqueline Kennedy, The Rothschild, his lovers etc. But none quite as complete and detailed the Douglass's piece. Other comparisons of writers who covered these era - Potash, Fanon, Chomsky, Lawrence Lipton as well as autobiographies and stories of popular celebrities of the time - Mohammad Ali, Bob Marley, Elvis, and more, the beatnik clash etc - all share a close resemblance on how CIA was ran and the control of the military industry during this time frame.
