The English aristocracy turns to an age-old institution to stave off war and strengthen political bonds - marriage. Debutantes flock to Germany, including Viviane Alden.

But they need evidence, photographs to tell the tale, and Viviane is a genius with her trusty Leica. And who would suspect a pretty, young tourist of being a spy?
