Gretchen Muller has three rules for her new life:
1. Blend into the surroundings.
2. Don't tell anyone who you really are.
3. And never, never go back to Germany.
The girl known as Gretchen Whitestone has a secret: she used to be part of Adolf Hitler's inner circle. When she made an enemy of her old family friend, she fled Munich for Oxford. Her love, Daniel Cohen, is a reporter in town, and Gretchen is content. Then a telegram calls Daniel back to Germany, and her world turns upside down when he is accused of murder.
To save Daniel, Gretchen must return to her homeland and somehow avoid capture by the Nazi elite. As they work to clear Daniel's name, they discover a deadly conspiracy stretching from the slums of Berlin to the Reichstag itself. Can they dig up the explosive truth and escape in time - or will Hitler find them first?
