I saw a clip of her repeating this story on a talk show. Of course, that doesn’t prove the validity of it or anything, but I do remember hearing her talk about it. She told it convincingly, seemed earnest, but I guess that’s what she was paid for anyhow.
Come to think of it, it might have been on the Mythbusters episode where they tried to replicate the effect (they couldn’t).
This one cracks me up.
Surreal!
Yes, she told it on the Dick Cavett show in the 1970s. But her story wasn’t about Communist spies during the Cold War, it was about Japanese spies during World War II.
