Locked room mystery for book club

Hello hello!

For my book club I’ve been tasked with choosing our next book, and the theme I’ve been given is “locked room mystery.” Any suggestions for a good book where we can actively follow the clues and try to solve the crime as we read?
Ideally, the book would play fair with the reader (no impossible twists with no setup), have a strong puzzle element or clever plottingp and spark lots of theories and debate.
Bonus points if it has a satisfying (or shocking) resolution that we can argue about afterward.

Thanks all 🙂
