American lady

Caroline de Margerie is a French writer and former diplomat. Available publisher biographies describe her as a former diplomat who later became a member of the Conseil d’Etat, France’s highest administrative court, and say that she lives in Paris.

She is the author of American Lady: The Life of Susan Mary Alsop, a biography first published in French and translated into English by Christopher Murray. The book follows Alsop from postwar Paris to Georgetown during the Kennedy years, showing de Margerie’s interest in the meeting point between private lives and public power.

From the information I could confirm, de Margerie writes nonfiction with a strong historical and biographical focus. Even in a story full of famous names and political glamour, her approach is centered on character, influence, and the social worlds that shape history.
