Marion and Huguette Müller’s family was torn apart when the Nazis invaded France in 1940. After their mother was deported to Auschwitz, the sisters fled to the small Alpine ski resort village of Val d'Isère, where they were rescued by a brave young doctor.

Through intrepid reporting and meticulous research, Whitehouse traces the story of the Müller sisters, solving decades-old mysteries in her attempt to deliver both closure and justice. With skill and urgency, Whitehouse raises moral questions at the heart of the tragedy of the Shoah: questions about complicity, culpability, about duty to your country and your fellow man. She sifts through thousands of records and pieces together how the sisters were saved, and how so many others were lost.

It is a tale full of shocking discoveries featuring a bloodthirsty killer, secret operatives of the French resistance, forged documents, narrow escapes, and miracles.
