I helped set up something like that for a friend’s milestone birthday, and it was a hit. The whole night turned into this funny mix of acting, guessing, and laughing at each other’s “serious detective” faces. If you want to make it easy, the murder mystery company organizes everything, from the plot to guiding guests into their roles. We even had people who didn’t know each other becoming partners-in-crime for the game. Definitely a great icebreaker.
