Forest Dweller

The basement. Although it seems the best place for the killer to be hiding, as darkness would be on their side, you doubt this killer is down there. After all, in the basement you can't prevent your victim from escaping the house. You head downstairs and notice a lock on the door. The basement door is now open- there's a chance that closing and locking behind you it could alert the killer to your position. It would, however, protect you.
