"I don't know. Nobody 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 passionately 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 passed 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 nobody 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.
