In Two Sisters, Rosie Whitehouse recounts the harrowing journey of her mother-in-law, Marion, and aunt, Huguette, who fled Nazi-occupied France after their mother was deported to Auschwitz. Seeking refuge, the sisters found themselves in Val d’Isère, where a courageous stranger, Dr. Frédéric Pétri, saved their lives. Whitehouse meticulously pieces together her family’s tragic history while probing ethical questions about courage and complicity during the Holocaust. Through vivid storytelling, she highlights the risks taken by individuals like Dr. Pétri to protect Jewish lives amid the horrors of Vichy France and her contemporary quest to recognize Dr. Pétri as a Righteous Among Nations.
