4.5 stars.

This was a reread, but enough time had passed that I had forgotten the "whodunit". The reread was just as entertaining as the first go round. I was quickly caught up in the story and the masterful writing. I am always impressed at how Christie can keep the answer so well hidden. Misdirection is everywhere and everyone becomes a suspect. I (just like my first read) had no idea who was the culprit until Christie herself revealed it in the end. Fantastically constructed.

There are a few instances of things not being quite PC, but I find that this is often where Christie's work has trouble standing the test of time. It can be cringeworthy on occasion, but I try to give it a little bit of a pass given the time in which these novels were written.
