about five o'clock
Hassan of Aleppo seemed to grow huge before my eyes like some ginn of Eastern lore . Then a curtain of darkness descended . I experienced a violent blow upon the forehead -LRB- I suppose I had pitched forward -RRB- , and for the time resigned my part in the drama of the sacred slipper . At about five o'clock that afternoon Inspector Bristol , who had spent several hours in Soho upon the scene of the murder of the Greek , was walking along Fleet Street , bound for the offices of the Report . As he passed the court , on the corner of which stands a branch of the London County and Provincial Bank , his eye was attracted by a curious phenomenon . There are reflectors above the bank windows which face the court , and it appeared to Bristol that there was a hole in one of these , the furthermost from the corner . A tiny beam of light shone from the bank window on to the reflector , or from the reflector on to the window , which circumstance in itself was not curious .
