The brief

Hercule Poirot investigates a murder aboard a train stopped by snow, where every passenger may have a motive.

The narrative controls what readers know, so clues and contradictions deserve attention alongside the apparent solution.

Character motives shape the suspense; notice how trust changes when new information alters earlier assumptions.

The setting and social relationships constrain the investigation, making context part of the mystery rather than decoration.

Pacing alternates revelation with uncertainty, inviting readers to test explanations instead of accepting the first plausible account.
