"After the Nazi victory over Poland in 1939, thousands of Poles were sent to Germany as slave laborers. From inside enemy territory, they found ways to get valuable information to resistance fighters in France. Paul Ricard, a French writer of detective novels, is drawn in to working in the resistance, as a spy against the Reich, and is charged with getting the information from the Polish prisoners to the Allied forces. Alongside him in the fight against Germany are an émigré girl and a mysterious Turkish woman who is in the contract espionage business."--

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 off to 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.
