In early 1941, the U.S.A. remains neutral in the war that threatens to destroy Europe and Asia and there are considerable forces working to keep it that way. In the meantime, it is the shipments of arms, munitions, and supplies from U.S. plants and shipyards that are keeping the British going in their fight against the Germans. But that is endangered when a series of "accidents" destroy docks, ships, and munitions plants. The FBI believes them to be unrelated accidents but the British, having broken the Ultra Code, knows that there is a master German spy at loose in the U.S. who is behind all of it. Blocked from operating in the U.S. by the FBI, MI-5 sends in a double agent - a Spaniard named Daniel Rucio who works for the German Abwehr and MI-5. For the Abwehr, he carries micro-dotted instructions to this unknown master spy - instructions to initiate the mysterious Operation Nothung. Following a trail from the East Coast to New Orleans to Hollywood, from darkened docks to glamorous Hollywood parties, it's up to Rucio to smoke out and chase down the German saboteur before he can carry out his orders. For if the saboteur succeeds, the last chance of the free world to resist the Nazi onslaught will be lost. The Double Agent is a classic espionage novel in the vein of the early Ken Follett or Frederick Forsyth, based on real historic events, brought to life by the critically acclaimed author of A Single Spy .
