Crooked House
I first read this for Halloween Bingo back in 2017. This is also the only Agatha Christie book in which I figured out who...okay, I guess I shouldn't say figured out. It was more like I thought, "Hey, I wonder if it could be 'so-and-so'?" I just had this nagging suspicion, but I couldn't quite say why I thought that way, and in the end, it turned out I was correct.
It was interesting to read it again, after knowing how it ends. I picked up on a lot of things that I'd missed--at least consciously--the first time around.
That being said, knowing who the killer was doesn't lessen the impact at all once the reveal is made.
