Extraños en el tren nocturno

The constant feeling of being watched made me uneasy, but I wondered if that was just my reading or a deliberate choice by the author to heighten suspense.

The setting added a layer of tension that kept me on edge. I'm curious whether this was a conscious decision to mirror the protagonist’s mental state or for another reason.

The twists felt so seamless and surprising, making me wonder about the process behind their placement and how much was mapped out beforehand.
