乗客ナンバー23の消失 (文春文庫)

The confined space of a cruise ship creates such tense dynamics. I wonder if the author was influenced by real events or just loved the idea of a closed environment for mystery.

It added such a layer of psychological complexity, but also made me question what was real. Did this make the story more immersive or frustrating?

The story kept me hooked without rushing, but I’d love to hear if the slow-burn buildup was a deliberate choice or just natural to the plot.
