Mafia 31. Twilight Dances.

Hmm, let me add something: even if someone is hesitant to execute Haven with such strong evidence, remember that we have an Angel who can save a player from the dungeon if needed. However, I don't think it will be necessary – if you look at Haven's profile, there's really not much evidence left to find. And I don't see any other good reason to delay the execution – if we find an Archer now (and with such evidence, it's not even that difficult to make a mistake), the Mafia will still have a few killers left, meaning we'll continue to lose 2 players per night.
Don't base your plans on other people's abilities, Ar. Unless you're Town, of course.
