War is coming to Europe.

British spymaster Barnaby Allen begins recruiting a network of agents in Germany. With diplomatic relations quickly unravelling, this pack of spies soon comes into their own: the horse-loving German at home in Berlin’s underground; the young American sports journalist; the mysterious Luftwaffe officer; the Japanese diplomat and the most unlikely one of all... the SS officer’s wife.

Despite constant danger and the ever-present threats of discovery and betrayal, Allen’s network unearths top-secret plans for a new German fighter plane – and a truly devastating intelligence prize... an audacious Japanese plan to attack the United States. But can they prove it?

The race is on.
