Disparu à jamais

The way the plot kept shifting kept me guessing until the very end. I loved that it didn't rely on obvious clues, but I wonder if others saw the surprises coming?

The pacing of the revelations felt carefully crafted, but I'm curious whether this structure was planned from the start or developed during writing. It added to the tension for me.

The characters' decisions often made me question what I would do in their place. Did anyone else find themselves sympathizing with characters they initially disliked?
