ゼロ時間へ (クリスティー文庫)

The plot's complexity kept me guessing until the very end. I'm curious whether she planned the entire puzzle from the start or let it evolve naturally.

The characters' motives and secrets made me question who was truly innocent or guilty. Did this moral complexity make the story more compelling or confusing?

The environment felt so deliberate in creating a sense of emotional distance. I wonder how much of that was based on real locations or purely fictional choices.
