The big war is over, and the Cold War has just begun. Leon Bauer, an American tobacco man, and his wife, Anna, a German Jew, made it to Istanbul just before World War II began. His U.S. passport and fluency in German and Turkish made him useful to Allied intelligence. But before he assumes a more peaceful life, Bauer is given a last big job — slip Alexi, a Romanian defector with important Soviet secrets, out of Istanbul. Alexi's secrets might help old allies — but the defector once helped massacre Jews in Romania. Bauer is being asked to help a man in this new war who represents what he fought in the last one.
