It takes a special sort of long-term determination and courage to risk one’s life for someone else’s sake. Would the friends who protected Anne Frank’s family in their secret annexe have embarked on their heroic act of altruism if they had known of the long haul ahead? In her remarkable novel, Night Falls on the City, Sarah Gainham imagines what it must have been like to keep a deadly secret in such circumstances for years. Julia Homburg is a famous classical actress whose family had been courtiers and Catholics, unassailable members of the Austrian imperial establishment. But Julia’s husband Franz Wedekind is a socialist politician and a Jew. Their story begins in March 1938.
