The room was dimly lighted by a lantern.
Ed found that he had been undressed also. He had nothing on but an old undershirt now.
After lying awake a long time he got up to see how he could stand it on his feet.
He found he was all right; a little shaky, perhaps, but so much better than he had been the night before that he felt that the effects of the drug had practically passed.
He tried the door and found it locked.
Window there was none. Escape thus seemed impossible, but the enterprising Ed did not give up.
He was resolved to know all about his prison before he did that.
In course of his search he took in the ceiling, and there he beheld a trap door.
It fascinated the boy, for it seemed to offer an avenue of escape.
No one coming, Ed resolved to make the attempt to reach it.
