In Paris's exclusive Saint-Germain neighborhood is a mansion. In that mansion lives a family. Deep in that mansion. The Bolts are that family, and they have secrets. The Safe House tells their story. When the Nazis came, Étienne Boltanski divorced his wife and walked out the front door, never to be seen again during the war. So far as the outside world knew, the Jewish doctor had fled. The truth was that he had sneaked back to hide in a secret crawl space at the heart of the house. There he lived for the duration of the war. With the Liberation, Étienne finally emerged, but he and his family were changed forever - anxious, reclusive, yet proudly eccentric. Their lives were spent, amid Bohemian disarray and lingering wartime fears, in the mansion's recesses or packed comically into the protective cocoon of a Fiat. That house (and its vehicular appendage) are at the heart of Christophe Boltanski's ingeniously structured, lightly fictionalized account of his grandparents and their extended family.
