It’s interesting to read a mystery written in a different era—the “rules” of a mystery are so different now. The differences range from little things (no editor would allow Poirot to ponder that he’d like to speak to someone and then have the person appear in the next sentence without a transition) to big things, like I’m fairly sure no modern mysteries are written as a straightforward conversation with one person after another.
And yet, Christie is the champion of murder mysteries for good reason. While I struggled sometimes with the old-style format, she definitely kept me guessing, and I definitely did not see the ending coming! I had most of the same information as the hero Poirot, and yet he maintains his reputation as a sleuth with an incredible mind.
This was the first Poirot Christie mystery I’ve read, and it was a grand adventure, if a bit stuffy.
