Richard Collier tells the story of how ordinary men and women from all walks of life risked torture and death in German-occupied Normandy to furnish the Allied forces with detailed information of the German coastal defenses, knowledge essential for D-Day success. Working from material both published and unpublished, Collier has created an authentic record of one of the most remarkable episodes of World War II, a human story of a group of ordinary people whose faith paved the way for Eisenhower's great sweep on D-Day.
