Le passé aux trousses (La cosmopolite)

The shifting viewpoints added layers of mystery but also made me wonder how much planning went into the narrative flow. Did the different perspectives come together in the writing process or evolve later?

The story had a strong start and a tense finish, but the middle section felt a bit slower. I'm curious if that was a deliberate choice to build suspense or just how the story unfolded.

The atmosphere felt very specific and immersive, which made me wonder whether the setting was based on a real place or a fictional creation. How did the author choose this particular backdrop?
