Les Secrets de la femme de ménage

The story sheds light on a hidden world within a seemingly perfect household. I'm curious what led to choosing this particular point of view.

The characters' loyalties kept changing, which made me question who to believe. Did this make the story more realistic or just more confusing?

The pacing kept me on edge but also allowed moments to breathe. I wonder if the story was planned this way or evolved during writing.
