El tren de Estambul

The confined setting creates such tension and intimacy — I wonder if Greene saw trains as a symbol for life's unpredictable twists.

The characters all seem to walk a fine line between right and wrong, which kept me guessing about who to trust. How did others interpret their choices?

His subtle, precise prose adds layers of meaning without over-explaining. I wonder if this style was a conscious choice to enhance the mystery.
