From The Shadows - James R. Benn

Following their mission in the Soviet Union, Billy, Kaz, and Big Mike are sent to southern France for what should be a simple assignment: to serve as security for Royal Navy Commander Gordon Stewart, head of the Special Operations Executive''s Section F in Algiers. Stewart''s mission is to work with Resistance leaders in liberated areas to gather information that will help track down Vichy officials and other traitors who escaped with the retreating Germans. With sacrifice and betrayal afoot, Billy doesn''t know who he can trust, or how close to death this case may bring him.
