"'Smoke,' was my first idea. 'Can there be anything on fire?' But I dismissed the notion almost as soon as it suggested itself. The something, faint and shadowy, that came slowly rippling itself in as it were beyond the dark wood of the open door, was yet too material for 'smoke.' My next idea was a curious one. 'It looks like soapy water,' I said to myself; 'can one of the housemaids have been scrubbing, and upset a pail on the stairs?' For the stair to the next floor almost faced the library door. But—no; I rubbed my eyes and looked again; the soapy water theory gave way. The wavy something that kept gliding, rippling in, gradually assumed a more substantial appearance. It was—yes, I suddenly became convinced of it—it was ripples of soft silken stuff, creeping in as if in some mysterious way unfolded or unrolled, not jerkily or irregularly, but glidingly and smoothly, like little wavelets on the sea-shore.

"And I sat there and gazed. 'Why did you not jump up and look behind the door to see what it was?' you may reasonably ask. That question I cannot answer. Why I sat still, as if bewitched, or under some irresistible influence, I cannot tell, but so it was.

"And it—came always rippling in, till at last it began to rise as it still came on, and I saw that a figure—a tall, graceful woman's figure—was slowly advancing, backwards of course, into the room, and that the waves of pale silk—a very delicate shade of pearly gray I think it must have been—were in fact the lower portion of a long court-train, the upper part of which hung in deep folds from the lady's waist. She moved in—I cannot describe the motion, it was not like ordinary walking or stepping backwards—till the whole of her figure and the clear profile of her face and head were distinctly visible, and when at last she stopped and stood there full in my view just, but only just beyond the door, I saw—it came upon me like a flash—that she was no stranger to me, this mysterious visitant! I recognised, unchanged it seemed to me since the day, ten years ago, when I had last seen her, the beautiful features of Maud Bertram."

Mr. Marischal stopped a moment. Nobody spoke. Then he went on again.

"I should not have said 'unchanged.' There was one great change in the sweet face. You remember my telling you that one of my girl-friend's greatest charms was her bright sunny happiness—she never seemed gloomy or depressed or dissatisfied, seldom even pensive. But in this respect the face I sat there gazing at was utterly unlike Maud Bertram's. Its expression, as she—or 'it'—stood there looking, not towards me, but out beyond, as if at some one or something outside the doorway, was of the profoundest sadness. Anything so sad I had never seen in a human face, and I trust I never may. But I sat on, as motionless almost as she, gazing at her fixedly, with no desire, no power perhaps, to move or approach more nearly to the phantom. I was not in the least frightened. I knew it was a phantom, but I felt paralysed, and as if I myself had somehow got outside of ordinary conditions. And there I sat—staring at Maud, and there she stood, gazing before her with that terrible, unspeakable sadness in her face, which, even though I felt no fear, seemed to freeze me with a kind of unutterable pity.

"I don't know how long I had sat thus, or how long I might have continued to sit there, almost as if in a trance, when suddenly I heard the front-door bell ring. It seemed to awaken me. I started up and glanced round, half-expecting that I should find the vision dispelled. But no; she was still there, and I sank back into my seat just as I heard my brother coming quickly upstairs. He came towards the library, and seeing the door wide open walked in, and I, still gazing, saw his figure pass through that of the woman in the doorway as you may walk through a wreath of mist or smoke—only, don't misunderstand me, the figure of Maud till that moment had had nothing unsubstantial about it. She had looked to me, as she stood there, literally and exactly like a living woman—the shade of her dress, the colour of her hair, the few ornaments she wore, all were as defined and clear as yours, Nina, at the present moment, and remained so, or perhaps became so again as soon as my brother was well within the room. He came forward addressing me by name, but I answered him in a whisper, begging him to be silent and to sit down on the seat opposite me for a moment or two. He did so, though he was taken aback by my strange manner, for I still kept my eyes fixed on the door. I had a queer consciousness that if I looked away it would fade, and I wanted to keep cool and see what would happen. I asked Herbert in a low voice if he saw nothing, but though he mechanically followed the direction of my eyes, he shook his head in bewilderment. And for a moment or two he remained thus. Then I began to notice that the figure was growing less clear, as if it were receding, yet without growing smaller to the sight; it grew fainter and vaguer, the colours grew hazy. I rubbed my eyes once or twice with a half idea that my long watching was making them misty, but it was not so. My eyes were not at fault—slowly but surely Maud Bertram, or her ghost, melted away, till all trace of her had gone. I saw again the familiar pattern of the carpet where she had stood and the objects of the room that had been hidden by her draperies—all again in the most commonplace way, but she was gone, quite gone.

"Then Herbert, seeing me relax my intense gaze, began to question me. I told him exactly what I have told you. He answered, as every "common-sensible" person of course would, that it was strange, but that such things did happen sometimes and were classed by the wise under the head of 'optical delusions.' I was not well, perhaps, he suggested. Been over-working? Had I not better see a doctor? But I shook my head. I was quite well, and I said so. And perhaps he was right, it might be an optical delusion only. I had never had any experience of such things.

"'All the same,' I said, 'I shall mark down the date.'

"Herbert laughed and said that was what people always did in such cases. If he knew where Mrs. —— then was he would write to her, just for the fun of the thing, and ask her to be so good as to look up her diary, if she kept one, and let us know what she had been doing on that particular day—'the 6th of April, isn't it?' he said—when I would have it her wraith had paid me a visit. I let him talk. It seemed to remove the strange painful impression—painful because of that terrible sadness in the sweet face. But we neither of us knew where she was, we scarcely remembered her married name! And so there was nothing to be done—except, what I did at once in spite of Herbert's rallying, to mark down the day and hour with scrupulous exactness in my diary.

"Time passed. I had not forgotten my strange experience, but of course the impression of it lessened by degrees till it seemed more like a curious dream than anything more real, when one day I did hear of poor Maud again. 'Poor' Maud I cannot help calling her. I heard of her indirectly, and probably, but for the sadness of her story, I should never have heard it at all. It was a friend of her husband's family who had mentioned the circumstances in the hearing of a friend of mine, and one day something brought round the conversation to old times, and he startled me by suddenly inquiring if I remembered Maud Bertram. I said, of course I did. Did he know anything of her? And then he told me.
