Nothing it seemed could break that image, corrupt that innocence, or disturb the swaying mantle of silence which, week after week, in the empty room, wove into itself the falling cries of birds, ships hooting, the drone and hum of the fields, a dog’s bark, a man’s shout, and folded them round the house in silence. Once only a board sprang on the landing; once in the middle of the night with a roar, with a rupture, as after centuries of quiescence a rock rends itself from the mountain and hurtles crashing into the valley, one fold of the shawl loosened and swung to and fro. Then again peace descended; and the shadow wavered; light bent to its own image in adoration on the bedroom wall; when Mrs. McNab, tearing the veil of silence with hands that had stood in the washtub, grinding it with boots that had crunched the shingle, came as directed to open all windows, and dust the bedrooms.
