Noisette Tornade was a member of the French Resistance in World War II.
Noisette coded messages for the French Resistance, but was also a French spy, translating for the Germans, from 1942 until the Liberation of Paris in 1944. After the war, she was tried for collaboration, and though she was acquited, she remained very bitter about it and decided to remain quiet about the stained glass she had hidden during the war so that it would not be destroyed. Noisette continued to work as a translator for Paris and was Director of Public Works from 1973 until 1995.
Noisette died when she was 85. She was fluent in English, French, German and Italian by the time she was 16.
When Nancy finds the stained glass in a bunker underneath Noisette's windmill in 2006, she also finds a letter Noisette left which states that she was not a traitor, nor was Hans von Schwesterkrank, her Nazi boyfriend who helped her protect the stained glass, meaning that he was loyal to the Germans. This puts an interesting twist on Noisette's judgement skills, especially since he was "the person she loved the most".
