304: Barbara Verica – Tracking Arne Treholt, Soviet Spy

Retired Agent Barbara Verica reviews her espionage case as a first-time, untrained, undercover agent in Manhattan, gathering intelligence and the evidence to prove that Norwegian diplomat Arne Treholt was selling secrets to the former Soviet Union.

The investigation was initiated on behalf of the Norwegian security service who had received information that Treholt, assigned as a member of the Norwegian delegation to the United Nations, was a spy. Barbara’s undercover task—move into the apartment next door and track Treholt’s movements. But things quickly became much more complex when Barbara became friends with Treholt’s wife, Kari Storækre.

(We previously reviewed this case in Episode 018, which was removed from the FBI Retired Case File Review backlist. During this episode, Barbara and I explained why she’s now free to talk about the investigation and agreed to a do-over.)

Barbara served in the FBI for 30 years.

She worked counter-intelligence matters in the New York and Philadelphia Divisions for the first 15 years of her career and investigated economic crimes in the Resident Agency out of Philadelphia for the last fifteen.

    Great episode, thanks. I just saw a Netflix documentary series on spies and one of them was Gordievsky. Fascinating character, he was a dedicated Marxist until 1968 when the Soviets put down the uprising in Prague.

      Thanks for listening. Gordievsky risked his life to provide significant intelligence the UK and US.
