"We're not in the Boy Scouts," Richard Helms was fond of saying when he ran the Central Intelligence Agency. He was correct, of course. Boy Scouts do not ordinarily bribe foreign politicians, invade other countries with secret armies, spread lies, conduct medical experiments, build stocks of poison, pass machine guns to people who plan to turn them on their leaders, or plot to kill men such as Lumumba or Castro or others who displeased Washington. The CIA did these things, and more, over a long span of years. On whose orders? This is a question a Pulitzer prizewinning writer addresses in an adaptation from his forthcoming book about Helms and the Agency, The Man Who Kept the Secrets.
