Morte na Rua Hickory

In this story, Poirot's sense of ennui seems to push him into the mystery more eagerly. Does his mood affect his detective work or is it just a character quirk?

The story seemed to drag a bit before the final reveal. Was that intentional to build suspense or a pacing choice that didn't quite land for me?

The setting feels so ordinary yet becomes the backdrop for such an intricate puzzle. I'm curious if the hotel was inspired by a real place or purely fictional.
