From David Wise's half-true book
Molehunt:
Chapter 11: AEFOXTROT
[Probable mole per MWT] George Kisevalter had greased the line.
The address in Manhattan that he had given to Yuri Nosenko before they [Nosenko, Kisevalter, and Tennent H. Bagley] parted in Geneva in [June] 1962 belonged to an agency asset. If anything came in to that address from abroad, signed by "Alex," it would mean that Nosenko was trying to recontact the CIA.
But Kisevalter did not trust even the best communications arrangements. He tested the link from time to time. They might never again hear from Nosenko, but if he did send a cable, a postcard, or a letter to the Manhattan address, it had to work.
"We had the line greased. I would send a cable to COS, Copenhagen. 'Send cable to following address in New York.' I sent periodic messages from Copenhagen, Geneva, and other places to keep the line activated. And to time it -- how soon would we know the message had arrived?" The timing was important, because the CIA was to meet Nosenko, in whatever city he was, under the movie marquee beginning with the highest letter of the alphabet three days after he sent the cable to the New York address.
At Langley, there had been changes since Nosenko's first meeting with the CIA in June 1962. Howard Osborn, who had replaced Jack Maury as chief of the Soviet division, had in turn been succeeded [a few months later] in 1963 by David E. Murphy. In the fall of 1962, Pete Bagley had come back from Switzerland and joined the division as a counterintelligence officer. Having been shown the Golitsin file by Angleton, he was now persuaded that Nosenko was a plant, a dispatched agent of the KGB.
Late in January 1964, Yuri Nosenko returned to Geneva with the Soviet disarmament delegation. "A cable came in to New York," Kisevalter said. "I found out within hours. I flew to Geneva and Bagley flew in separately."
"Bagley met him [Nosenko] under the marquee of the movie theater in Geneva. He gave Nosenko a note with the address of the safe house. We went to a different safe house from the one we used in 1962."
And so the first of half a dozen meetings in the new safe house began. Nosenko did not know, of course, that one of the two CIA case officers he was meeting with -- Pete Bagley -- now believed him to be a Soviet plant.
It was only two months after the Kennedy assassination. Lyndon Johnson was in the White House, and the Warren Commission, which Johnson had appointed to investigate the murder of President Kennedy, was about to begin hearing the first of 552 witnesses.
The tragedy in Dallas was on everyone's mind, but what Nosenko now told Kisevalter and Bagley staggered the two CIA men. He had, he assured them, personally handled Lee Harvey Oswald's case [and his KGB file four times before and after the assassination] when the former Marine arrived in Moscow and asked to [be allowed to] remain in the Soviet Union.
"Oswald came up almost immediately," Kisevalter recalled. "We questioned Nosenko about every detail on Oswald." What Nosenko told the two CIA men was that the KGB had decided it had no interest in Oswald. And Nosenko added that he was the official who ordered that Oswald be told he would have to leave when his visa expired.
When Oswald then attempted suicide, Nosenko continued, his decision to order Oswald to leave the Soviet Union was overruled by other officials outside the KGB who had decided it would be best, under the circumstances, to let Oswald stay. According to Kisevalter, when Nosenko was asked why the Soviets had reversed themselves, he replied: "Because he tried to commit suicide. There would only be adverse publicity if he tried it again." As Nosenko later explained it to a congressional committee, the Soviets concluded that if Oswald did succeed in killing himself, the reaction in the press would harm "the warming of Soviet-American relations."
LOL
If the Ruskies were so afraid Oswald would try to commit suicide again, why then didn't they just pronounce him
Persona Non Grata, bundle him up, and take him to the American Embassy? Instead, they let the Marine Corps radar operator, who had monitored the U-2 spy plane and knew about the marines' new height-finding radar, etc, etc, stay there for
two-and-a-half years ...
