From an Amazon Captain Hugh North of the G-2 division of military intelligence is in Washington, D.C. working on counterintelligence matters. A recent wave of spying has resulted in the loss of American tank designs and other valuable military secrets to several foreign powers. Much of the spying has been attributed to a mastermind called simply the Guardsman because his real name is unknown to his adversaries. North and his ally, Major Bruce Kilgour of British Army Intelligence, must put a stop to the Guardsman before more military secrets are stolen. This story was written after Adolph Hitler rose to power and Germany, Japan and even Russia had all become likely enemies in any future war.
