As an undercover operative for the Office of Strategic Services during World War II, Evelyn Bishop routinely embarked on deadly missions. By contrast, civilian life should be simple. Yet Evelyn, now back in Los Angeles, struggles with the responsibility of being the new president of Bishop Aeronautics, when people see her as nothing more than a beautiful socialite.

With Nick Gallagher, at least, Evelyn can be entirely herself. Once a fellow spy, now her fiancé, Nick works as a private investigator. But the mission that first brought them together is not entirely over. Evelyn receives a call from her former commanding officer, who is overseeing the Berlin Airlift. He is concerned that the Soviets are trying to recruit Kurt Vogel, a scientist Evelyn and Nick smuggled out of Nazi Germany. After six long years, there's word his wife and daughter may have survived the war. Is this a chance for a long-promised reunion, or a Russian ploy to lure Vogel to their side?

Past and present collide again when a routine case offers Nick a reunion with a childhood friend who runs a high-class "gentleman's club." The clientele includes everyone from Hollywood royalty to mobsters—to a hidden enemy who will draw both Evelyn and Nick into a web as twisted and treacherous as any they have ever faced . . .
