Now with new evidence, experts hope to solve this heist. Dark Secrets of the CIA It's the Cold War's dirty little secret: a terrifying account of the CIA's efforts to expose unknowing members of the public to biological agents, hallucinogenic drugs and psychological techniques aimed at mastering the art of mind control.
