An over the top who-done-it, like knives out or Murder by Death!

I’m not sure if it entirely fits your criteria, but I’d love to recommend: Win, Lose, Kill, Die by Cynthia Murphy! It’s really shocking! And Suddenly a Murder by Lauren Muñoz. None of these fit your criteria but both are who-done-its murder mysteries, and I just wanted to recommend two of my favourites! 😁🙈
