The Mystery of the Blue Train

This one was a fun read! It had a unique feel among her books - more of an international crime novel - but the characters were quite fleshed out and there were several different people's perspectives in the book. Poirot felt a little caricaturized (of course he always does, but more so here, maybe because it was an early book?) so I missed some of his more pointed reflections on human nature, but Katherine Grey made up for it.
