She takes her orders from Valdar Boris Karloff, the butler. However, unbeknownst to her, he is a British double agent. Valdar later secretly reports to Colonel Yeats Leonard Mudie, the head of British Intelligence.When Bennetts secretary, also a German spy, taps out a secret message in code on her typewriter, Yeats is present and recognizes it. Since only Hautry is also in the office at the time, he sets a trap for her. A captured spy named Kurz seemingly escapes from the British and flees to Hautrys bedroom. She hides him in her closet, but then betrays him when Yeats and his men show up. Afterwards, she tells Valdar that she knew Kurz was an imposter. ........
