Although Renée Garry was a frequent guest at her brother Émile’s—sometimes when Noor was also staying there—she herself did not work for the Resistance. Some historians suspect that Renée possibly had a crush on France Antelme, who also often stayed at Garry’s. Perhaps she was therefore jealous of the close relationship that developed between Noor and Antelme. For whatever reason, Renée called a member of the Gestapo and offered to give him Noor’s address for one hundred thousand francs. As pointed out in The Flames of Resistance, Madeleine (Noor) was one of the Gestapo’s most-wanted and was worth ten times the amount of money Renée had demanded.  

The instructions the Gestapo agent gave Renée were simple: she was to meet at the Trocadéro near the Eiffel Tower, holding a flower. A man named “André,” who would be carrying a magazine under his arm, would approach her and introduce himself. 

What Renée didn’t know was that André was armed and that another Gestapo agent, also armed, was nearby. If anything went wrong, André and his accomplice had been instructed to kill Renée. 

The address Renée gave André was an older one: Noor had vacated that apartment after the incident in the park with Robert Gieules. 

A not-so-pleased André arranged to meet Renée at a café. This time Renée gave him the Rue de la Faisanderie address (the apartment Viennot had arranged for Noor). Renée accompanied André to the apartment, where they found Noor’s radio and notebooks, in which Noor had recorded all of her messages. André took note of everything and left it all where he had found it. 

On October 13, 1943, Renée once again called the Gestapo to let them know that Noor was at the Rue de la Faisanderie address. 

Two agents arrived at Noor’s apartment building to watch a young, dark-complected woman wearing a blue dress with white trim (the dress Viennot had purchased for her) leaving the ground-floor cafe. Noor spotted them and disappeared around the corner. One of the agents, Pierre Cartaud, used the key Noor had left for Émile and waited for her to return. 

Six hours later, she did. 

She struggled so much against Cartaud that he called for reinforcements. Ernest Vogt was one of the backup men and later described the scene: 

Pierre was standing covering her from the farthest possible corner of the room and Madeleine, sitting bolt upright on the couch, was clawing the air in her frustrated desire to get at him and looked exactly like a tigress. 

Cartaud was bleeding heavily and Vogt said he’d never seen such fury from a woman.
