Network correspondent Jake Geismar, who covered Berlin before the war, has returned to the devastated city, ostensibly to cover the Potsdam Conference but actually to find the woman he loves. Miraculously, Lena Brandt, Jake's wartime mistress, has survived. However, her mathematician husband is missing, and both the American and Russian intelligence services are hunting him. When the bullet-ridden body of an American soldier washes up on the shores of Potsdam in front of Jake's eyes just as Truman, Churchill, and Stalin convene the first postwar conference, Jake is plunged into a maelstrom of intrigue, corruption, and betrayal.
