6:30
But my attention was diverted and my mind changed by seeing a man coming down the stairs before me , of so fine a figure that I involuntarily stopped to look at him . Had he moved a little less carelessly , had he worn his workman 's clothes a little less naturally , I should have thought him some college bred man out on a slumming expedition . But he was entirely too much at home where he was , and too unconscious of his jeans for any such conclusion on my part , and when he had passed out I had enough curiosity to ask who he was . `` My interest , you may believe , was in no wise abated when I learned that he was that highly respectable tenant whose window had been open at the time when half the inmates of the two buildings had rushed up to his door , only to find a paper on it displaying these words : Gone to New York ; will be back at 6:30 . Had he returned at that hour ? I do n't think anybody had ever asked ; and what reason had I for such interference now ? But an idea once planted in my brain sticks tight , and I kept thinking of this man all the way to the Bridge .
