Beginning with a daring operation to smuggle the Polish National Gold Reserve to the government in exile, he slips into the shadowy and treacherous front lines of espionage; he moves through Europe, changing identities and staying one step ahead of capture. In Warsaw, he engineers a subversive campaign to strengthen the people's will to resist. In Paris, he poses as a Russian poet, then as a Slovakian coal merchant, drinking champagne in black-market bistros with Nazis while uncovering information about German battle plans. And a love affair with a woman of the French Resistance leads him to make the greatest decision of his life.
