"i crossed to that corner and found a dirty dark staircase. i heard a man mounting up above me, some way higher than i was, and thinking i should catch him before his door would be opened to him, i rushed after him. i heard a door open and shut on the fifth storey, as i panted along; the stairs were narrow, and the steps innumerable, but at last i reached the door i thought the right one. some moments passed before i found the bell and got it to ring.
