"Priscilla may have been an evil, evil CIA agent." (paraphrased)
Priscilla Johnson checked in with CIA SR/10 "Legal Travelers" Chief, Army MAJOR Alexander "Sasha" Sogolow, in Frankfurt while on her way to, or coming home from, Moscow in 1956.
Sogolow was the KGB mole whom false defector Yuri Nosenko kinda alluded to when he told Tennent H. Bagley and (probable mole) George Kisevalter in Geneva in January-February 1964 that there was an Army CAPTAIN in West Germany who was spying for the KGB, and he was the CIA boss of Igor Orlov/ Alexander "Sasha" Kopatzky, aka Anatoly Golitsyn's mole, SASHA, in Germany.
Bagley says in his 2007 book, "Spy Wars" (which you can read for free by googling "spy wars" and "archive" simultaneously), that the CIA didn't follow up on this "lead" because U.S. Army Captains in Germany were a-dime-a-dozen.
We learn from Newton S. Miler in David Wise's book, "Molehunt," that Sogolow confessed in the 1960s, wasn't prosecuted, and was "played back" against the KGB for a few years.
Igor Orlov/Alexander Kopatzky was "uncovered" by probable mole Bruce Solie in 1966, five years after Orlov had retired from the CIA, and did so based on a "tip" from Kremlin-loyal triple agent Igor Kochnov (KITTY HAWK). Look him up. He's the guy whose mother-in-law, Yekaterina Furtseva, allegedly overrode Nosenko and allowed Oswald to stay in the USSR.
I could go on and on, but that's enough for now.
Hopefully, one of these days you'll tell us about the man with the Slavic surname who was living with the Solie family on their dairy farm when future probable mole, Bruce, was an impressionable lad.
