In real life, he was Albrecht Dittrich, a highly-trained Soviet sleeper agent dropped behind enemy lines in 1970s America. When the KGB recalled him to Europe, Barsky had a difficult choice to make: Should he leave his wife and 18-month-old baby behind or betray his country?

Hayley Atwell tells the story of how Soviet engineer Adolph Tolkachev became one of the Cold War's most prolific turncoats.

Vanessa Kirby gets Christo Grozev, a modern Sherlock Holmes, to share the secrets of how he solved one of the most notorious assassination attempts of the 21st century - the poisoning of retired Russian double-agent Sergei Skripal, hospitalized by a mysterious nerve agent on British soil.

Undercover CIA agent James Olson takes Vanessa Kirby on a nail-biting mission behind the Iron Curtain.

Could YOU evade detection?

How do you flee your country and join the other side? A former Russian intelligence agent gives Vanessa Kirby a rare masterclass in international tradecraft.

Vanessa Kirby tells his story.

Bill Browder’s fund made billions in the wake of the Soviet Union's collapse. But in the new Russia, the cost of doing business could be counted in more than cash.

In the fall of 1973, journalist Emil Draitser met an aging Soviet super-spy. His name was Dmitri Bystrolyotov, and for him, sex and secrets went hand-in-hand. At the time, Emil could scarcely believe what he heard - much less publish it. Thirty years later, long after the collapse of the USSR, Dmitri's story could finally be told. Vanessa Kirby enters a world of seduction, secrets, and lies between the wars. Could YOU mix business and pleasure?

Who was Britain's Ace of Spies? Nobody really knows but the name he used was Sidney Reilly - and nobody did it better in the early 20th century. Reilly reckoned with oil barons, his personal pride, and the rise of Communism during his decades on the edge.
