But he could think of no means of escape. He spent many hours thinking of his life before he was captured, regretting the mistakes he had made and dreaming of the joys he had known. And over and over he said to himself that he was being punished for no reason. He was guilty of no crime, but he had not been given a chance to explain the events which made it appear that he was guilty. Then one night the guard who sat just outside of the prisoner''s door fell asleep. When he noticed this, the prisoner was struck by a feeling of hope. Perhaps he could steal the keys while the guard was dozing. Silently the prisoner moved towards the guard. Very gently he lifted the ring of keys from the guard''s belt. Then he turned and crept toward the door. Could he work the lock from the inside? The key turned and the door swung open. Within two minutes he had crossed the yard, and climbed the wall. Then he fled across the fields, free at last, a smile of joy beginning to spread across his face.
