One day, a curious thing happened. In the midst of lunch, Lady Agnes sprang up from table with a joyful but hysterical laugh, and declared that Walter was coming on horseback, and she must go and meet him. Quick as thought she had her hat on, and rushed out of the house, the nurse following at a little distance, anxious to see what would happen.

Lady Agnes walked swiftly across the park to a little wicket-gate in the wall, where Warren used to meet her. Then she stopped and looked along the path, while the nurse hid behind the trunk of a beech tree at a short distance. In a few minutes Agnes cried out, “I hear him—I hear him; it is his footstep.” Then a minute afterwards she flung out her arms as if embracing some one, and cried, and seemed to kiss the air, uttering warm words of affection. The nurse saw nothing—only a light puff of wind stirred the leaves and caused a rustling.

Agnes in a few moments turned to the right, and began to walk, or rather glide, as it seemed to the excited fancy of the nurse, at a swift pace, all the while talking as if to some person who accompanied her, and every now and then pausing to throw her arms round his neck, and uttering an hysterical sob. She made straight for “The Pot,” and went quickly round the oak stump. The nurse followed rapidly, and as she peeped round the oak there was Lady Agnes facing her on the other side of “The Pot,” with both arms extended and her face white as death. “Walter,” she said, distinctly; “Walter, what does that red spot on your forehead mean? Are you angry?” Then she fell prone on the grass in a dead faint, and the nurse had immense trouble to get her home again.

Just a month afterwards came the news that Walter was dead, having been shot in the forehead with a ball from a matchlock while leading on his men. He had won much praise by his desperate courage, and the last despatch recommended him for promotion, and for the Cross for saving life under heavy fire.

Now, looked at dispassionately by others, the whole incident resolves itself into a case of excitement and over-anxiety acting upon a naturally sensitive organisation. But it was easy to see how to Lady Agnes the affair wore a very different light. To her the imaginary shape, invisible to others, which had met her at the little wicket-gate, was real—the spirit of her lover, which had come from the wilds of China, over thousands of miles, to acquaint her in dumb show of the destruction of its body.

From that moment she became a devout believer in the power of the dead to revisit their friends. She was not alarmed. On the contrary, the thought soothed her. She expected and waited for Walter’s second approach, and spoke lovingly when he came again. For he, or the unsubstantial vision in his form, did come again and again, and always in one of two places—in the Blue Room, or beside “The Pot.” That strange freak of Nature had been the favourite resort of the lovers in the bygone time. Agnes counted the time for the approach of the spirit; those who waited upon her could tell when she believed the time for the appearance was near, by the peculiar light in her eyes, and the glow upon her cheek. At such times the superstitious servants hastened to get out of the room. After a while Agnes became conscious that these things were noticed and commented upon, and it became her practice, when she felt the time coming, to retire to her own room and lock herself in.

Reflecting upon these periodical visits of what she really believed was the spirit of her dead lover, Agnes naturally went on to consider the whole question of the existence of supernatural beings. She purchased works upon demonology and witchcraft, and being an accomplished scholar did not confine her studies to her own language, but read deeply in Agrippa, and the necromancers of the Middle Ages. There were those who said that while upon the Continent she plunged into these forbidden mysteries, and found in the recesses of foreign capitals, men with whom there still lingered the knowledge how to control the spirits of the air. In part this was true; whether self-deceived or not, it was certain that Agnes really believed there were genii with whom she could converse almost at pleasure. How was it then that, always anxious for Warren’s presence, she yet disliked The Towers?

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.
