In preparation for the 1936 Berlin Olympics, the Nazis have rid the streets of anti-Semitic material and other propaganda, and present a peace-seeking face to the world. Journalist and part-time spy for the British, Hannah Vogel, shudders to think of what lies under the temporary coat of gloss.

Posing as travel reporter Adelheid Zinsli and lover of SS officer Lars Lang, Hannah has been collecting Nazi secrets from Lang and smuggling them back to Switzerland. Wanted by the SS, her travel in and out of Germany has always been fraught with danger, but this trip is especially treacherous.

Surrounded by former colleagues who could identify her, Hannah tries to keep a low profile while reporting on the Games as Adelheid. Her relationship with Lang gets more complicated as he sinks into alcoholism; the whispers she hears about his work in the SS give her chills. Whose side is he on?

Hannah agrees to meet her mentor, Peter Weill, at the Stadium, but before he can reveal information that will expose the Nazis, he dies in front of her. Hannah suspects poison.

Hannah must discover who killed Weill and get his secret package out of the country before the Olympics end and the Nazis tighten their noose…and before her true identity is revealed. And her partner may be the very one about to expose her…
