Адский поезд для Красного Ангела (Мировой детектив)

The psychological depth of the antagonist really stood out to me. I wonder what inspired the author to explore this dark perspective so intensely.

The pacing kept me on the edge of my seat, but I'm curious if others found the quick escalation effective or a bit overwhelming.

The confined space created such a claustrophobic atmosphere. I wonder if the author envisioned the train as a symbol for the characters' entrapment from the start.
