The wealth of shadows : a novel / Graham Moore.

1939. Ansel Luxford has everything a person could want--a comfortable career, a brilliant spouse, a beautiful new baby. But he is obsessed by a belief that Europe is on the precipice of a war that will grow to consume the world. The United States is officially proclaiming neutrality in any foreign conflict, but when Ansel is offered an opportunity to move to Washington, D.C., to join a clandestine project within the Treasury Department that is working to undermine Nazi Germany, he uproots his family overnight and takes on the challenge of a lifetime. How can they defeat the enemy without firing a bullet? 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.
