Ludmilla Serebrennikov
From Tardis Wiki, the free Doctor Who reference
Ludmilla Serebrennikov was a Russian spy during the mid-20th century.
She worked for the Nazis and the Russians. Around the end of World War II she decided to seek greener pastures and go to America. She turned a discredited scientist over to the KGB as part of a deal to leave Russia. During the exchange, her glasses were irreparably damaged. Ironically, instead of boarding a train heading west, she got on one heading east to Stalin's death camps. She was unable to escape and was killed. (PROSE: Warlock)
