At the top of the stairs is a door. You open it slowly to reveal a short dark pathway with a door at the end. You make your way to the second door. The first door closes slowly behind you and you hear a click. You go back to the first door and realize it's locked. You slowly turn and keep walking to the second door with your grip tightening around the hairpin. You see there is a lock on the door. A heavy set lock with a keyhole.What do you do?
