We played Cluedo.

The first round went quickly so we played a second round. In this round, all of us realized at about the same time that something was wrong. Just as Ingrid was saying “hm, that doesn’t add up” and Eric commented that he must have made a mistake in his note-taking, I was realizing that my notes didn’t allow for anyone to be the murderer. Somehow we had put two place cards and one murder weapon in the envelope (instead of one place, one murderer and one weapon).
