Margery was with Hitler on his birthday when he was presented with the Tiger Tank. As a singer she was able to remember some critical technical data as a song which was sent back to Bletchley Park for decoding via her controller Hardy Amies and to the delight of Churchill who then ordered the capture of one. She had a narrow escape whilst hiding British airmen and was eventually caught by the Gestapo on the personal orders of Goering after being constantly shadowed by SS thug von Müller who eventually tortured her.
