L'ospite indesiderato

Some of the confrontations felt a little exaggerated, but I wonder if that was intentional to heighten the suspense or just my perception.

The confined setting really ramps up the claustrophobia and paranoia, but I'm curious whether the author considered other locations or this was a deliberate choice.

The pacing of reveals kept me guessing, but I wonder if the structure of the story was planned from the start or evolved during writing.
