Gabrielle “Coco” Chanel was the high priestess of couture who created the look of the modern woman. By the 1920s she had amassed a fortune and went on to create an empire. But her life from 1941 to 1954 has long been shrouded in rumor and mystery, never clarified by Chanel or her many biographers. Hal Vaughan exposes the truth of her wartime collaboration and her long affair with the playboy Baron Hans Günther von Dincklage—who ran a spy ring and reported directly to Goebbels. Vaughan pieces together how Chanel became a Nazi agent, how she escaped arrest after the war and joined her lover in exile in Switzerland, and how—despite suspicions about her past—she was able to return to Paris at age seventy and rebuild the iconic House of Chanel.
