Todos en este tren son sospechosos

The book balances wit and suspense in a way that kept me engaged without losing the tension. Did the humor feel natural to others or did it sometimes undercut the seriousness?

The confined space heightens the suspense but also creates a unique dynamic among characters. I'm curious whether this setting was a deliberate choice or evolved during writing.

Switching viewpoints kept the mystery fresh but also challenging. I wonder if this narrative approach was planned from the start or developed during revisions.
