Elephants Can Remember

I loved the little moments with Mrs Oliver, and her approach to solving crime. However–

slight spoilers ahead–

I was hoping for another twist at the end. I saw the main twist coming, and I was actually expecting the plot to go one step further. In the end, there were several threads left open that could have really gone together, and it felt like they'd been neglected.

I'm definitely not the first reviewer to say that, and it's totally understandable given how late in Christie's career this came out. I still had fun with it as a character study, so my advice is just be along for the ride and don't put too much stress on the puzzle! :)
