L'ombre du caméléon

The shifting viewpoints added layers to the mystery, but I wonder if that was planned from the start or evolved during writing.

The characters' choices felt complex and realistic, but it made me question what I would do in their place. Am I the only one who struggled with sympathizing with them?

The atmosphere really heightened the suspense, and I'm curious whether the setting was based on a real place or a fictional creation.
