about six o'clock
Only six days -- was it possible ? Ah , yes ! She knew when her spell was weakening , when the current wanted , as it were , renewing . And about six o'clock -- dusk already -- without the least surprise , with only a sort of empty quivering , he heard her knock . And just behind the closed door , as near as he could get to her , he stood , holding his breath . He had given his word to Sylvia -- of his own accord had given it . Through the thin wood of the old door he could hear the faint shuffle of her feet on the pavement , moved a few inches this way and that , as though supplicating the inexorable silence .
