The Scarlatti inheritance - Robert Ludlum

Her weapons: Money and Power. Her target: The most dangerous man in the world—her son. Elizabeht Wyckman Scarlatti has a plan—a desperate, last-minute gamble—designed to save the world from her own son, Ulster, an incalculably dangerous man who is working under the name of Heinrich Kroeger: Unless she can stop him, he is about to give Hitler's Third Reich the most powerful triumph on earth.
