In his 2007 book, "Spy Wars," former CIA officer Tennent H. Bagley said that in October 1968 Solie "cleared," via a bogus polygraph exam and a specious report, false defector Yuri Nosenko, an ostensible KGB officer (who didn't know how to send cables or where the cafeteria was in KGB headquarters, etc) who had been sent to the CIA in Geneva in June 1962 to discredit what recent true defector Anatoliy Golitsyn was telling James Angleton about KGB "moles" in the CIA, the FBI, and the intelligence services of our NATO allies.
In "Uncovering Popov's Mole," John Newman says Angleton told his confidant, mentor and mole-hunting superior, Solie, what Golitsyn had told him, and that Solie relayed this information to KGB headquarters via moles in French intelligence and a highly mobile KGB officer by the name of Mikhail Tsymbal so that Nosenko's boss in Moscow, KGB General Oleg Gribanov, could modify his legend and make him more effective at discrediting Golitsyn.
