Then the knocking began, the terrible brazen knocking which soulless iron makes on the unresponsive door of an empty house. It was as if whoever knocked frightened himself by the knocking, and tried to beat away his fear with still louder blows. But to the woman who tried to pretend that the house was really empty it was more terrible still. It seemed to take on the sound of a summons to the soul itself to issue forth. The noise of it flooded the place, echoed its way upstairs and into far rooms, so that strange voices answered it sharply from wood and stone. The heavy, storm-tried walls were suddenly no more than paper, so that the knocking became folly when a push would have forced them in. It seemed to Sarah that they must hear it from end to end of the marsh, across at the ’Ship,’ and out to the hidden edge of sea. She wondered why Simon did not come running, and the dog break into hoarse barks, for even in the far shippon they must surely hear. But there was only that great knocking in all the world, cheerful, impatient, or resigned by turn. It paused at moments, but only as the passing-bell pauses, Sarah thought, waiting to speak its single word afresh. The noise had swept away in a moment both the false serenity of hate and the almost falser calm of that dwelling memory of love. From the respite, indeed, the live passion seemed to have sunk, as it were, on its haunches for a fiercer leap. She could not think clearly or control her limbs under the sudden impact of its spring. It seemed to fling itself on her as she had seen the tides in the winter crash against the wall. She, too, went under as if the water had beaten her down, and the noise at the door became the blows of the waves and the roar of the dragged beach. She had that impulse to laughter which comes with long-expected woe, as if the gods were guilty of bathos when they stooped at last to strike. Scorn is the first sensation of those who seem to have watched the springs of action long before the hour. Sudden sorrows, quick blows have a majesty of their own, as if the gifts of the gods made for honour in good or ill. But long-deferred trouble, like suspended joy, has a meaner quality in fulfilment, and a subtle humiliation in its ache. That when the gods come they come quickly is true for both libations from the emptied cup. Royal sorrows, like royal joys, fall swift as thunderbolts from heaven.
