Mafia 37. Haven of Evil.

Gentlemen, there are currently 12 of us alive. If the zombies continue to spread the infection, they need to infect 6 more people to win. Currently, only 3 are infected. We have 3 more nights to figure out what's going on. Guards, change your objective. We already know you're not Arandor; now, show us that you're not someone else either. Any information is helpful in this situation.
