Biography
She met George and Clyde Langer on their way to alert the Home Guard, and told them the whole village had been surrounded by Germans. She had a gun with her. She pretended to help the boys capture the Nazis in the church, but revealed that she was a double agent. She fled with Koenig and the other Nazis when George and Clyde stopped their plan to use a machine to block British radio signals and invade without being detected. (SJA: Lost in Time)
