I read this for book club back in early March. After discussing it there I made my review lower. There really weren‘t enough characters for a locked room mystery. And there was discussion of the twist being that there is no twist and how it plays out the way you think it would. While I loved The Silent Patient, it seems like Michaelides‘ books are on a downhill trajectory from there. I‘d get this one from the library if you want to read this one.
