To thwart the Nazis, Ansel and his team invent a powerful new theater of battle: economic warfare. Money is a dangerous weapon, and Ansel's efforts will plunge him into a world full of peril and deceit. He will crisscross the globe to broker backroom deals, undertake daring heists, and spar with titans of industry like J. P. Morgan and the century's greatest economic mind, Britain's John Maynard Keynes. When Ansel's wife takes a job with the FBI to hunt for spies within the government, the need for subterfuge extends to the home front. And Ansel discovers that he might be closer to those spies than he could ever imagine.
