midnight
I veered up and down the neighboring avenues . But it was useless . The man in the velour hat was gone . Then , to my surprise , as I paced the midnight streets , a sense of physical weariness crept over me . I realized that I had walked for miles . I had forgotten my own troubles and that most kindly of all narcotics , utter fatigue , crept through me like a drug . So I went home and went to bed .
