As soon as I could, I escaped to my room, and I was sitting there over a book, when the maid--her name was Hopkins, I had discovered--came in on the pretext of inquiring if I had everything I needed. One of the innumerable servants had already turned down my bed, so when Hopkins appeared at the door, I suspected at once that there was a hidden motive underlying her ostensible purpose.

"Mrs. Vanderbridge told me to look after you," she began. "She is afraid you will be lonely until you learn the way of things."

"No, I'm not lonely," I answered. "I've never had time to be lonely."

"I used to be like that; but time hangs heavy on my hands now. That's why I've taken to knitting." She held out a gray yarn m.u.f.fler. "I had an operation a year ago, and since then Mrs. Vanderbridge has had another maid--a French one--to sit up for her at night and undress her. She is always so fearful of overtaxing us, though there isn't really enough work for two lady's-maids, because she is so thoughtful that she never gives any trouble if she can help it."

"It must be nice to be rich," I said idly, as I turned a page of my book. Then I added almost before I realized what I was saying, "The other lady doesn't look as if she had so much money."

Her face turned paler if that were possible, and for a minute I thought she was going to faint. "The other lady?"

"I mean the one who came down late to dinner--the one in the gray dress.

She wore no jewels, and her dress wasn't low in the neck."

"Then you saw her?" There was a curious flicker in her face as if her pallor came and went.

"We were at the table when she came in. Has Mr. Vanderbridge a secretary who lives in the house?"

"No, he hasn't a secretary except at his office. When he wants one at the house, he telephones to his office."

"I wondered why she came, for she didn't eat any dinner, and n.o.body spoke to her--not even Mr. Vanderbridge."

"Oh, he never speaks to her. Thank G.o.d, it hasn't come to that yet."

"Then why does she come? It must be dreadful to be treated like that, and before the servants, too. Does she come often?"

"There are months and months when she doesn't. I can always tell by the way Mrs. Vanderbridge picks up. You wouldn't know her, she is so full of life--the very picture of happiness. Then one evening she--the Other One, I mean--comes back again, just as she did tonight, just as she did last summer, and it all begins over from the beginning."

"But can't they keep her out--the Other One? Why do they let her in?"

"Mrs. Vanderbridge tries hard. She tries all she can every minute. You saw her tonight?"

"And Mr. Vanderbridge? Can't he help her?"

She shook her head with an ominous gesture. "He doesn't know."

"He doesn't know she is there? Why, she was close by him. She never took her eyes off him except when she was staring through me at the wall."

"Oh, he knows she is there, but not in that way. He doesn't know that any one else knows."

I gave it up, and after a minute she said in a suppressed voice, "It seems strange that you should have seen her. I never have."

"But you know all about her."

"I know and I don't know. Mrs. Vanderbridge lets things drop sometimes--she gets ill and feverish very easily--but she never tells me anything outright. She isn't that sort."

"Haven't the servants told you about her--the Other One?"

At this, I thought, she seemed startled. "Oh, they don't know anything to tell. They feel that something is wrong; that is why they never stay longer than a week or two--we've had eight butlers since autumn--but they never see what it is."

She stooped to pick up the ball of yarn which had rolled under my chair.

"If the time ever comes when you can stand between them, you will do it?" she asked.

"Between Mrs. Vanderbridge and the Other One?"

Her look answered me.

"You think, then, that she means harm to her?"

"I don't know. n.o.body knows--but she is killing her."

The clock struck ten, and I returned to my book with a yawn, while Hopkins gathered up her work and went out, after wishing me a formal good night. The odd part about our secret conferences was that as soon as they were over, we began to pretend so elaborately to each other that they had never been.

"I'll tell Mrs. Vanderbridge that you are very comfortable," was the last remark Hopkins made before she sidled out of the door and left me alone with the mystery. It was one of those situations--I am obliged to repeat this over and over--that was too preposterous for me to believe even while I was surrounded and overwhelmed by its reality. I didn't dare face what I thought, I didn't dare face even what I felt; but I went to bed shivering in a warm room, while I resolved pa.s.sionately that if the chance ever came to me I would stand between Mrs. Vanderbridge and this unknown evil that threatened her.

In the morning Mrs. Vanderbridge went out shopping, and I did not see her until the evening, when she pa.s.sed me on the staircase as she was going out to dinner and the opera. She was radiant in blue velvet, with diamonds in her hair and at her throat, and I wondered again how any one so lovely could ever be troubled.

"I hope you had a pleasant day, Miss Wrenn," she said kindly. "I have been too busy to get off any letters, but tomorrow we shall begin early." Then, as if from an afterthought, she looked back and added, "There are some new novels in my sitting-room. You might care to look over them."

When she had gone, I went upstairs to the sitting-room and turned over the books, but I couldn't, to save my life, force an interest in printed romances after meeting Mrs. Vanderbridge and remembering the mystery that surrounded her. I wondered if "the Other One," as Hopkins called her, lived in the house, and I was still wondering this when the maid came in and began putting the table to rights.

"Do they dine out often?" I asked.

"They used to, but since Mr. Vanderbridge hasn't been so well, Mrs.

Vanderbridge doesn't like to go without him. She only went tonight because he begged her to."

She had barely finished speaking when the door opened, and Mr.

Vanderbridge came in and sat down in one of the big velvet chairs before the wood fire. He had not noticed us, for one of his moods was upon him, and I was about to slip out as noiselessly as I could when I saw that the Other One was standing in the patch of firelight on the hearth rug.

I had not seen her come in, and Hopkins evidently was still unaware of her presence, for while I was watching, I saw the maid turn towards her with a fresh log for the fire. At the moment it occurred to me that Hopkins must be either blind or drunk, for without hesitating in her advance, she moved on the stranger, holding the huge hickory log out in front of her. Then, before I could utter a sound or stretch out a hand to stop her, I saw her walk straight through the gray figure and carefully place the log on the andirons.

So she isn't real, after all, she is merely a phantom, I found myself thinking, as I fled from the room, and hurried along the hall to the staircase. She is only a ghost, and n.o.body believes in ghosts any longer. She is something that I know doesn't exist, yet even, though she can't possibly be, I can swear that I have seen her. My nerves were so shaken by the discovery that as soon as I reached my room I sank in a heap on the rug, and it was here that Hopkins found me a little later when she came to bring me an extra blanket.

"You looked so upset I thought you might have seen something," she said.

"Did anything happen while you were in the room?"

"She was there all the time--every blessed minute. You walked right through her when you put the log on the fire. Is it possible that you didn't see her?"

"No, I didn't see anything out of the way." She was plainly frightened.

"Where was she standing?"

"On the hearthrug in front of Mr. Vanderbridge. To reach the fire you had to walk straight through her, for she didn't move. She didn't give way an inch."

"Oh, she never gives way. She never gives way living or dead."

This was more than human nature could stand. "In Heaven's name," I cried irritably, "who is she?"

"Don't you know?" She appeared genuinely surprised. "Why, she is the other Mrs. Vanderbridge. She died fifteen years ago, just a year after they were married, and people say a scandal was hushed up about her, which he never knew. She isn't a good sort, that's what I think of her, though they say he almost worshipped her."
