Virginia Hall, a young American woman--rejected from the foreign service because of her gender and her prosthetic leg--talked her way into the spy organization dubbed Churchill's "ministry of ungentlemanly warfare," and, before the United States had even entered the war, became the first woman to deploy to occupied France. She was one of the greatest spies in American history, and a shockingly overlooked heroine of the Second World War till now. At a time when sending female secret agents into enemy territory was still strictly forbidden, Virginia Hall came to be known as the "Madonna of the Resistance," coordinating a network of spies to blow up bridges, report on German troop movements, arrange equipment drops for Resistance agents, and recruit and train guerilla fighters. Even as her face covered WANTED posters throughout Europe, Virginia refused order after order to evacuate. She finally escaped with her life in a grueling hike over the Pyrenees into Spain, her cover blown, and her associates all imprisoned or executed. But, adamant that she had "more lives to save," she dove back in as soon as she could, organizing forces to sabotage enemy lines and back up Allied forces landing on Normandy beaches. This is the breathtaking story of how one woman's fierce persistence helped win World War II.
