"Q33" was the nom-de-plume of England's most efficient spy. This book deals with his breathless exploits against Germany during the war, in company with his young assistant, Philip Phayle. Beautiful women spies, plans in cypher, German secret service officials and a crowd of other exciting people and events throng the pages of this hair-raising story. Q33 will appeal to all who can appreciate the desperate dangers of espionage in German territory during the war; and the dauntless courage and bravery of spirit displayed on both sides a that never-ceasing combat to the death between brain and master-brain.
