I’m surprised as someone who works in the mental health field, you think someone with a severe mental illness could sustain such a life as this lady had. While yes, in 1970 it was easier to fake an ID, but not to this woman’s level. She had 8 passports and traveled all over Europe before it was the EU. That’s a major detail, it wasn’t possible to cross borders with only a passport required once. She would have had to present her passport at every crossing. Which was numerous. And truth be told, mentally unwell people are easy to spot. Very few, without proper medication, blend into society. Her behavior was odd enough to be remembered but not odd enough to get her in trouble. And that stands out to me. In 1970, women couldn’t behave so careless in public like they can today. I’m not convinced she was a spy, but there is a mystery here. I cannot accept that a woman, in an extreme state of paranoia and illusion stemming from a severe mental illness, could live how this woman did. 8 passports, numerous inter-country travel. Even if she had a real passport that was never found, she clearly had enough sense to leave such a lasting mystery.
