Mafia, no narrator needed

1. Everyone gets a secret role. Peek at your card, then keep a straight face.
2. Night falls. Every phone says the same thing, so nobody can tell who is doing what.
3. The Mafia whack someone. The Doctor plays hero. Villagers point at whoever looks shifty.
4. Morning brings the body count, and what they were.
5. Argue. Lie. Swear on your mother. Then vote someone out, or chicken out.
6. Catch every crook and the town wins. Let them match your numbers and the Mafia own the place.
