Suzanne David Hall (born 1927) was a spy for the French resistance during World War II. While training to become an opera singer, she relayed messages that helped bring about the Allied invasion of Normandy. The 2003 novel For Freedom: The Story of a French Spy by Kimberly Brubaker Bradley was based on interviews with Hall. The German's forced Hall and her family to move out of their house and into a dingy apartment. Hall never told her name to any of the other spies. To them, she was spy number 22, the 22nd spy in Cherbourg, where she lived.
