Hi,

No idea what this was about, but nothing about Griet Zelle (performing under the name Mata Hari) suggests she was a spy. Since she lived so close-by in her youth, her history gets the occasional mention here. As the whole affair is more than a hundred years ago, the archives about her are now accessible to the public, but still nothing about spies. Griet fled when her father went broke, and she seems to have lived her life to always make sure people provided her with enough money. That's not really anything special, and neither is it that she liked boys wearing uniforms and boys not wearing uniforms.
If there is something to say about her, fine, but please write something that makes sense.

Bye
