It’s almost the end of the war and Paul Peachy, a young railway employee and amateur actor in Milwaukee, realizes his marriage is one-sided. He enlists, and ships off to France. Peachy instantly realizes how out of his depth he is—and never more so than when he is captured. Risking everything, Peachy—who as a child of immigrants speaks German—makes the reckless decision to impersonate one of the enemy’s most famous spies. As the urbane and accomplished spy Harry Stroller, Peachy has access to a world he could never have known existed—a world of sumptuous living, world-weary men, and available women. But when one of those women—Annie, a young, beautiful and wary courtesan—turns out to be more than she seems, Peachy’s life is transformed forever.
