The mission: to kill the three most important and heavily guarded men in the world.

The assassins: a specially trained team headed by the killer known as the Most Dangerous Man in Europe.

The stakes: nothing less than the future of the Western world.

The year is 1943. Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin are meeting for the first time at a top-secret conference in Tehran. But the Nazis have learned about the meeting, and Hitler sees it as his last chance to turn the tide. And so a plan is devised—code-named Operation Long Jump—to assassinate FDR, Churchill, and Stalin.

A hand-picked team of Nazi commandos have six days to complete the daring assignment. With no margin for error and little time to spare, Mike Reilly, the head of FDR’s Secret Service detail—a man from a Montana silver-mining town who describes himself as “an Irish cop with more muscle than brains”—must overcome his suspicions and instincts to work with a Soviet agent from the NKVD (the pre-cursor to the KGB) to save the Allied leaders.
