She maintained an intimate affair with Koslov for two years and committed to spying on behalf of the Soviet Union after the KGB threatened to deport him to Siberia.

In 1955, she returned to Oslo but continued her espionage activities through a Soviet handler.

She was arrested by Norwegian security police at the Bråten tram stop on 27 January 1977 after she had been betrayed by Oleg Gordievsky.

She allegedly confessed to the crimes and died under mysterious circumstances in prison before the case could come to trial.
