Ernest Hemingway was Part of the OSS
Ernest Hemingway is one of the greatest American novelists who has profoundly influenced the 20th Century Fiction. The 1954 Nobel Literature Prize winner also worked as an ambulance driver in World War I.
If we believe the words of Nicholas Reynolds (ex-CIA spy), then Hemmingway might have been recruited by NKVD in 1940. The Soviets tasked Hemmingway with passing on political information to them. However, no substantial information ever made its way through him. Additionally, he also spied for the OSS (1940 version of the CIA). His biographer believes that the dual allegiance might have been a reason for his suicide in 1961. He shot himself with his favorite shotgun that he got access to by unlocking the basement’s storeroom.
