Book 15 of 2021 was The Turn of the Key by Ruth Ware. A solid 4.5 star read. It was obvious from the beginning that there was something fishy going on but I never figured it out. The main character was hiding something, that was a no brainer, but again I hadn't even come close to the truth in my speculations. I found my self listening any time I could just to try to figure it out. As the truth came out I found myself sitting with my jaw on the table so to say. It wasn't a full 5 stars as there were a few things that when I reflected were just a little too unbelievable for me, but all in all a quick, suspenseful read.
