In this thrilling historical spy novel from New York Times bestselling author Alan Furst, two heroic resistance fighters smuggle valuable information to occupied Paris to turn the tide of the World War II and defeat Nazi Germany. Occupied Paris in 1942, a dark, treacherous city now ruled by the German security services, where French resistance networks are working secretly to defeat Hitler. Just before he dies, a man being chased by the Gestapo hands Paul Ricard a strange looking drawing. It looks like a part for a military weapon; Ricard realizes it must be an important document smuggled out of Germany to aid the resistance. As Ricard is drawn deeper and deeper into the French resistance network, his increasingly dangerous assignments lead him to travel to Germany, and along the underground safe houses of the resistance–and to meet the mysterious and beautiful Leila, a professional spy.

From an incomparable expert at his game (The New York Times) and based on true events of Polish prisoners in Nazi Germany, Under Occupation captures the courageous and astonishing impact resistance fighters had during WWII and the lengths they went for freedom.
