Sonya’s Red Heart, Part Two: The Secrets of Sonya | GRU

Ursula Kuczynski, AKA Agent Sonya, is one history's most effective spies. As an intelligence gatherer for the Soviet military, she helped to usher in the age of Mutually Assured Destruction during the bloody 1940s.

In 2020, a newly declassified document muddied the waters - who was Sonya really working for?

In this two-part True Spies story, a new theory deepens the mystery of her life and work.

In Part 2, Sophia Di Martino and Professor Anthony Glees explore a masterful double-cross by the Stalinist spy.
