For the second time my use of Mr. Rayner’s name had acted like a charm; and I wondered how this woman, who had dared so much to cut me off from communication with Laurence, could calmly submit to receive orders from me.

After tea, Mrs. Rayner in her turn surprised me by a warning which seemed to show keen observation. She came and stood by me at the fireplace while Sarah was clearing the table, and once, while the latter was for a moment out of the room, breathed softly into my ear, without turning her head—

“Take care—she hates you, and she is dangerous.”

I glanced up quickly; but Sarah was already back in the room, and Mrs. Rayner’s face was as impassive as ever.

I was so much used to living in fear of Sarah that the warning did not make any particular impression upon me, and I went to bed neither more nor less afraid of her machinations than usual.

I woke up in the night without being conscious of any cause for doing so. I had started at once into full wakefulness, and I saw that Haidee was sleeping quietly, and that the fire was still alight, but had burnt low; and I thought I would replenish it.

Then, as I raised myself on my elbow, I thought I heard a sound, too faint to be called a noise, outside the door. So I kept quite still and listened intently. I heard nothing for some time, then again a muffled noise as of something being shuffled softly from one stair to another, then again no sound. The turret staircase was uncarpeted; it had once been polished, but the beeswax had worn off long since and had not been renewed. I got out of bed softly, lighted my candle by putting a match to the dying fire to avoid the noise of striking it, crept to the door, and literally put my ear to the keyhole. And, after a few moments, I heard the same soft shuffling again. It might be Nap, Mr. Rayner’s retriever, trying to find a stair softer than the rest to lie upon; yet they were surely too narrow for him to make the attempt.

Whoever or whatever it was seemed to be making its way down by very slow degrees, until it seemed that it must be about six or seven stairs from the top. I screwed up my courage and resolved to give the intruder, human or otherwise, a fright. All the locks were kept in good condition at the Alders, and there was not such a thing as a creaking door in the place. I turned the key without the least noise, then the handle, and flung open the door, stamping my foot and brandishing the candle. I heard Haidee scream; I had forgotten her.

My plan succeeded only too well. A figure which had been crouching on the stairs sprang up. It was Sarah.

Before I had time to do more than recognize the savage frightened face, her foot slipped, and, with a piercing cry, she fell backward down the stairs. The staircase had one turn. I, trembling at the door, saw her long thin hands clutching and struggling to save herself at the corner; but she failed, and I heard a heavy thud, and then a groan. She had fallen headlong to the bottom.
