Petits meurtres entre voisins

The confined setting really amplifies the tension, but I wonder if the author based it on real social dynamics or created it from imagination.

The rapid shifts in loyalty kept me on edge, but I'm curious if that was intentional to mirror real-life suspicions or just for plot twist.

The story unfolds with enough clues to keep guessing while also deepening the characters' motives. I'm interested in whether this was planned from the start or evolved during writing.
