After failing at a prestigious music AcadÉmie, nineteen-year-old Marie-ThÉrÈse is finally meeting with success at a Brussels nursing school. But in August 1914, just as her third and final year begins, German armies invade Belgium, swiftly overcome the Allies, and press on toward France, leaving behind an occupying force. This upends everything in Brussels and in Marie-ThÉrÈse's world. There are reports of ongoing brutalities which fuel burgeoning resentment on the part of the citizenry. Although the occupiers must be treated with respect, nothing prevents citizens from venting their anger on fellow citizens of German descent, including Marie-ThÉrÈse's family. At the clinic and nursing school, a newly installed director orders students and staff to spy on one another. In this perilous environment, the matron of the school—a character based on the historical Edith Cavell—makes a fateful decision. Soon, so does Marie-ThÉrÈse. Both have far-reaching consequences. IN THE FALL THEY LEAVE is a wartime story of moral courage, resilience, and endurance.
