A Thing

People in the town slowly begin disappearing one by one as the citizenry begin to get suspicious. The town turns into a veritable game of mafia, or werewolf. Nobody trusts anybody anymore as people keep on disappearing. Eventually there are five citizens - including yourself - left trying to decide who the killer is before it is too late...

Isaak and Kain both seem suspicious, but so far no-one has said anything outright damning.
