The door was locked, and Rudolph was left alone.
When five minutes had elapsed—time enough for his captors to get away—he rose in bed, and looked about him.
Beside the bed in which he was lying there was no other furniture in the room than a wooden chair.
He got up and walked about.
"I must get away from this if I can," thought the tramp, "and before morning. I am glad they didn't put on handcuffs. Let me see, how shall I manage it."
He looked about him thoughtfully.
It was a basement room, lighted only by windows three feet wide and a foot high in the upper part of the room.
"I should like to set fire to the building, and burn it up," thought the tramp. "That would cost them something. But it wouldn't be safe. Like as not I would be burnt up myself, or, at any rate, be taken again in getting away. No, no; that won't do."
"I wonder if I can get through one of those windows?" was the next thought that came into his mind.
