A secret war. A shattered mission. A betrayal buried inside British intelligence.

In 1948, as postwar Europe fractures and Stalin's grip spreads across Eastern Europe, two British operatives are sent behind the Iron Curtain on a mission that no one expects them to survive. Former SOE agent Luba Haas and newly minted MI6 officer Natalie Jenkins are tasked with supporting the Polish resistance and reactivating a long-silent sleeper agent. But from the moment they cross into Soviet-occupied territory, they know something is wrong.

The operation has been compromised. There's a mole inside British intelligence. Hunted by the Soviet MGB and Polish security forces, cut off from all support, and surrounded by their enemies, the women must navigate a web of coded signals, dead drops, and shifting loyalties - where every ally could be a foe, and every message could be a trap.
