Agent Sonya: Moscow's Most Daring Wartime Spy
by Ben Macintyre
Agent Sonya is the latest book by Ben Macintyre, who has made an art of writing nonfiction books about spies that read like thrillers (If you haven’t read The Spy and the Traitor yet, you must). Agent Sonya was the codename of Ursula Kuczynski, a German Jew who ended up living in an English village and spying for the Russians.
