You decide to climb over the wall to the other side with one of the prisoners following you. What you find on the other side is a short hallway with a hole broken through the one end. On the other side of the hole is a dark tunnel dug into the earth leading away from the basement. The other end of the hall leads to an empty wall and there's a door to your left. There's no sign of the doctor or anyone else in the hall. What are you going to do now?
