The year is 1943 and the three Allied leaders—Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin—are at a top-secret conference in Tehran.

Even as a team of Nazi commandos is assembled and parachuted into Iran, Secret Service agent Mike Reilly must overcome his suspicions and instincts to work with a Soviet agent from the NKVD, and as Howard Blum recounts in this thrilling true story, they have less than six days to save the three most powerful men in the world.
