After groping her, KGB agents found a small receiver she had hidden. She was questioned for hours then kicked out of the country.
Later, she found out the CIA had itself been compromised. In 1984, the FBI arrested Karl Koecher after learning he was a KGB mole who once worked for the CIA as a translator. Koecher had a played a role in Trigon's downfall and ultimately in Peterson's arrest.
"I had that feeling I had made a mistake. But it was clearly an ambush in my case," said Peterson, who published a book last year about her experience, "The Widow Spy."
Almost a year after she was caught, the KGB in 1978 publicly revealed Peterson's CIA employment, payback for the FBI disclosing the arrest of three Soviet spies in the U.S.
Newspaper reports carried the Soviet claim that she was a "CIA agent" who was involved in a plot to poison one of their citizens. She worked for the CIA but the rest of the story was fiction.
Fogle was waylaid, too, raising questions about what happened.
Former CIA officials told The Associated Press that little about his case makes sense. Disguises are typically used to leave the U.S. Embassy in Moscow and sneak past nearby Russian observation points. But once an officer runs the final phase of his detection route, there would have been no need for a wig, much less two.
It's also unlikely, officials said, that Fogle would have been recruiting anyone at that time. Typically, that would have happened already in another setting. You don't use the streets of Moscow to sign up a spy, they said. And the source would have been checked before any face-to-face meeting. He would have been assessed and then developed before any recruitment.
