“Decades later, however, spectacular revelations cast Olson’s death in a completely new light. First, the CIA admitted that, shortly before he died, Olson’s colleagues had lured him to a retreat and fed him LSD without his knowledge. Then it turned out that Olson had talked about leaving the CIA – and told his wife that he had made “a terrible mistake”. Slowly, a counter-narrative emerged: Olson was disturbed about his work and wanted
to quit, leading his comrades to consider him a security risk. All of this led him to room 1018A.”
