Recs if you like That Night in the Library...

... You're trapped here with me! The format: A group of people (could be strangers, or long-lost friends) are gathered or trapped in an isolated place together. Maybe it's a remote island. Maybe a cozy cabin during a blizzard. Someone is killed. The killer is obviously among them, but who?! Submissions welcome because this is my favourite mystery sub-genre at the moment, and I can't wait to discover more!
