借镜杀人 (阿加莎·克里斯蒂作品)

The confined setting amplifies the tension and secrets among characters. I'm curious if Christie envisioned this location from the start or it evolved during writing.

The layers of deception added a chilling undertone to the story. I wonder if this reflects common themes in Christie’s work or a specific message about human nature.

Christie’s plotting always feels so precise, but I sometimes miss the hints. Do you think she intentionally misleads readers or just plants clever clues?
