Der Mann, der Rockefeller war: Aufstieg und Fall eines bayerischen Hochstaplers

I'm curious about the research process behind uncovering the details of this impostor's life. Did the author have access to firsthand sources or interviews that shaped the narrative?

The level of deception is astonishing, but it also made me wonder about our own vulnerabilities. How do we guard ourselves against trusting appearances too easily?

It feels like a delicate balance between revealing enough to keep readers hooked and respecting privacy. What guided those choices during the storytelling process?
