"when did you come, rahmun? " i asked him. "last evening," he said, "i was released from jail." the words struck harsh upon my ears. i had never before talked with one who had wounded his fellow, and my heart shrank within itself when i realised this; for i felt that the day would have been better-omened had he not turned up.
