Betrayed! - Last Plane out of Paris, #5

Blending fact and fiction, this tale of adventure is set in 1940 and follows two men as they parachute into occupied France to rescue an aircraft designer, a man whose designs could decide the fate of the war. Split into 6 parts, this account of the one of the darkest times of World War 2 is a rip roaring tale that will have readers eagerly turning the pages right through to the thrilling end. In Part 5, Bill realizes that there is only one reason that the Germans have always been one step ahead of them.
He'd put it down to bad luck, but now the ugly truth rears its head. There's a traitor! Is it Marie, the charming resistance agent? Or is it Pierre, the man who seems to crush every German that comes in his way? Or is it Marcella, the aircraft designer?
