Ladoux, convinced that Zelle was a spy, became determined to catch her in an act of espionage. He recruited her to work for French intelligence, sure that she was a double agent for the Germans. In early 1917, Ladoux later arrested and interrogated Zelle, and garnered what he took as a confession: She admitted to taking money from the Germans, though she firmly denied having ever provided them with any useful espionage. On Oct. 14, Mata Hari was executed by firing squad. Newspaper reports described her as refusing to wear a blindfold and blowing kisses to the soldiers who raised their rifles against her. Now, 100 years after the execution, the archives of her interrogation and trial have been opened to the public, and her complicated, extraordinary life is being reassessed and commemorated in the Netherlands, the country that she tried to leave behind at age 19. The Museum of Friesland in Leeuwarden is staging a biographical exhibition devoted to her life, while the Dutch National Ballet in Amsterdam is reprising a contemporary ballet, “Mata Hari,” which premiered in 2016 to great popular success. A theater piece focused on her mysterious life and performed by the singer and actor Tet Rozendal is also touring the country. “Her story is still relevant in that she’s a woman who does not conform to society’s norms, and to anyone else’s ideas,” said Ted Brandsen, the managing director of the Dutch National Ballet. “She’s really about female transgression: She breaks through the limits of respectability.” The commemorations in the Netherlands all attempt to separate the myth of Mata Hari from the truth of Margaretha Zelle’s life. But Zelle often presented herself as someone else from somewhere else — as Mata Hari, the exotic princess from the East — and her compatriots have had an uneasy relationship with her persona ever since.
