Soon after she began to study these magical books, and to attempt to penetrate the veil which covers the ethereal world from the eyes of poor humanity, it appeared to her that whenever Walter came, his face wore a sad aspect, almost of upbraiding. And beside him there rose up a Darkness: something without form and void, and yet which was there—something which chilled her blood. After a while it began to take the shape of a thin column of darkness; even in the broad sunlight there was this spot where no light would penetrate. It came too without Walter; it rose up in the middle of the room where she sat—a dark presence, a shadow which haunted her everywhere. I cannot explain this; I can only record that it was the case. It was this that made Agnes dislike The Towers, and live in the new wing. Yet even there she did not escape. The shadow took a shape. There is a sentence in a certain grand old book, which prays that we may be delivered from the pestilence which walketh in darkness. The thought of that is awful enough. But there is something more awful still. Ancient books, which mention such things in a far-off manner, as if one were speaking under the breath, refer in a dim way to the noonday phantom—the phantom which meets the huntsman at midday in the green and shady wood; which stops the maiden at the fountain with her pitcher, in the glare of the sunbeams; which addresses the shepherd suddenly upon the hillside as he watches his sheep under the blue vault of the sky. To the darkness and the night, the spirits seem to have a natural claim—it is their realm; the boldest of us have sometimes felt an unaccountable creeping in the thick darkness. But at noonday, when one would naturally feel safe, by one’s side in the daylight, this is a thousand times worse. The noonday phantom came to Agnes. The dark shadow, the thin column of darkness like smoke, took to itself a shape. Chapter Four.
