《螺丝在拧紧》 / The Turn of the Screw

《螺丝在拧紧》 / The Turn of the Screw is the Henry James novella used in 69.闲聊推理文学：历史学者可不就是侦探吗！ as one route into detective-fiction origins. The episode treats it as gothic on the surface but methodologically adjacent to mystery because it asks whether ghosts, perception, repression, social position, and narrative reliability can be separated.

Its value in the source is not that it becomes a Holmes-style case. It shows that ambiguity and interpretive pressure predate clean detective rationality. That makes the work a useful bridge to Interpretation And Overinterpretation and Semiotic Detective Fiction: the reader has to decide what kind of sign a haunting is before deciding what happened.
