A new book by British journalist and author Rose Whitehouse explores the story of a doctor named Frédéric Pétri who risked his life to save a Jewish girl during the Nazi occupation of the French Alps. The book, titled 'Two Sisters: Betrayal, Love, and Resistance in Wartime France,' delves into the moral questions surrounding Pétri's actions and why more people didn't do the same. The story also highlights the cooperation between the French and Jewish Resistance, the Vichy government's collaboration with the Nazis, and the lasting impact of the war on French society. The book is a family memoir, a historical account, and an examination of the Holocaust in France.
