Die Haushälterin: Ein absolut packender Psychothriller voller Twists

The character's dual nature kept me guessing, but I'm curious what inspired the author to explore this complex moral ambiguity.

I found myself wanting more revelations but also appreciated the build-up. Was this deliberate to deepen the psychological tension?

It added layers to the story, but I wondered whether this was planned from the start or evolved during writing. What was the thought process behind this approach?
