1941. Dieter Merz is the Reich's most celebrated fighter ace and his aerial prowess has brought him into close contact with the top echelons of Hitler's regime. Even so, everything in the Nazi state still comes at a price. If Dieter wants help for an injured friend, he must inform on the modest, lifelong confidant always at Hitler's side: Rudolf Hess.
Meanwhile Scotsman and ex-marine Tam Moncrieff is working for M15, attempting to sound out Germany's intention of withdrawal. With most of Europe already fallen to Hitler's armies, Germany considers the war won. Berlin would be only too happy to call off the bombers and the U-boats in exchange for a formal peace treaty. But only if the English to turn their backs on Europe and attend to their precious Empire — leaving Germany the rest of the territorial spoils.
With Churchill refusing to negotiate and intelligence agencies at each other's throats, Rudolf Hess becomes the unexpected catalyst that changes the fortunes of the war.
