Blut will reden: Eine wahre Geschichte von Mord und Maskerade

The book reads like a detective novel but is rooted in actual events. I'm curious what drew the author to this particular case and how he approached telling it.

The way the impostor was depicted made me question how well we can really know someone. Did others feel a sense of unease about trusting appearances after reading this?

The narrative kept me guessing but also provided enough context to understand the complexity of the case. I'm wondering how the author decided what to disclose upfront.
