I'm a little way into The Silent Companions by Laura Purcell. Not sure how I feel about it yet.

Finished Gentlemen and Players by Joanne Harris (dark academia mystery thriller): someone seeks revenge on a British boys' school; chapters alternate between the antagonist and the school's retirement-aged Latin teacher. I liked it enough to put the sequel on my TBR, but I stand by my previous comment that it could stand to be juuuuust a bit shorter.
