The tramp was wary. He waited for ten minutes or so. Some women came down a path to the road and inspected the automobile. When they had gone, he crawled into the box-car and closed the door again. Then he lighted a match. The figure of a man, unconscious, gagged, and with his hands tied, lay far at the end.

The tramp lost no time; he went through his pockets, found a little money and the cuff-links, and took them. Then he loosened the gag-it had been cruelly tight-and went his way, again closing the door of the box-car. Outside on the road he found the watch. He got on the fast freight east, some time after, and rode into the city. He had sold the cuff-links, but on offering the watch to Alex he had been "copped."

The story, with its cold recital of villainy, was done. I hardly knew if I were more anxious, or less. That it was Halsey, there could be no doubt. How badly he was hurt, how far he had been carried, were the questions that demanded immediate answer. But it was the first real information we had had; my boy had not been murdered outright. But instead of vague terrors there was now the real fear that he might be lying in some strange hospital receiving the casual attention commonly given to the charity cases. Even this, had we known it, would have been paradise to the terrible truth. I wake yet and feel myself cold and trembling with the horror of Halsey's situation for three days after his disappearance.

Mr. Winters and Alex disposed of the tramp with a warning. It was evident he had told us all he knew. We had occasion, within a day or two, to be doubly thankful that we had given him his freedom. When Mr. Jamieson telephoned that night we had news for him; he told me what I had not realized before-that it would not be possible to find Halsey at once, even with this clue. The cars by this time, three days, might be scattered over the Union.

But he said to keep on hoping, that it was the best news we had had. And in the meantime, consumed with anxiety as we were, things were happening at the house in rapid succession.

We had one peaceful day-then Liddy took sick in the night. I went in when I heard her groaning, and found her with a hot-water bottle to her face, and her right cheek swollen until it was gla.s.sy.

"Toothache?" I asked, not too gently. "You deserve it. A woman of your age, who would rather go around with an exposed nerve in her head than have the tooth pulled! It would be over in a moment."

"So would hanging," Liddy protested, from behind the hot-water bottle.

I was hunting around for cotton and laudanum.

"You have a tooth just like it yourself, Miss Rachel," she whimpered. "And I'm sure Doctor Boyle's been trying to take it out for years."

There was no laudanum, and Liddy made a terrible fuss when I proposed carbolic acid, just because I had put too much on the cotton once and burned her mouth. I'm sure it never did her any permanent harm; indeed, the doctor said afterward that living on liquid diet had been a splendid rest for her stomach. But she would have none of the acid, and she kept me awake groaning, so at last I got up and went to Gertrude's door. To my surprise, it was locked.

I went around by the hall and into her bedroom that way. The bed was turned down, and her dressing-gown and night-dress lay ready in the little room next, but Gertrude was not there. She had not undressed.

I don't know what terrible thoughts came to me in the minute I stood there. Through the door I could hear Liddy grumbling, with a squeal now and then when the pain stabbed harder. Then, automatically, I got the laudanum and went back to her.

It was fully a half-hour before Liddy's groans subsided. At intervals I went to the door into the hall and looked out, but I saw and heard nothing suspicious. Finally, when Liddy had dropped into a doze, I even ventured as far as the head of the circular staircase, but there floated up to me only the even breathing of Winters, the night detective, sleeping just inside the entry. And then, far off, I heard the rapping noise that had lured Louise down the staircase that other night, two weeks before. It was over my head, and very faint-three or four short m.u.f.fled taps, a pause, and then again, stealthily repeated.

The sound of Mr. Winters' breathing was comforting; with the thought that there was help within call, something kept me from waking him. I did not move for a moment; ridiculous things Liddy had said about a ghost-I am not at all superst.i.tious, except, perhaps, in the middle of the night, with everything dark-things like that came back to me. Almost beside me was the clothes chute. I could feel it, but I could see nothing. As I stood, listening intently, I heard a sound near me. It was vague, indefinite. Then it ceased; there was an uneasy movement and a grunt from the foot of the circular staircase, and silence again.

I stood perfectly still, hardly daring to breathe.

Then I knew I had been right. Some one was stealthily-pa.s.sing the head of the staircase and coming toward me in the dark. I leaned against the wall for support-my knees were giving way. The steps were close now, and suddenly I thought of Gertrude. Of course it was Gertrude. I put out one hand in front of me, but I touched nothing. My voice almost refused me, but I managed to gasp out, "Gertrude!"

"Good Lord!" a man's voice exclaimed, just beside me. And then I collapsed. I felt myself going, felt some one catch me, a horrible nausea-that was all I remembered.

When I came to it was dawn. I was lying on the bed in Louise's room, with the cherub on the ceiling staring down at me, and there was a blanket from my own bed thrown over me. I felt weak and dizzy, but I managed to get up and totter to the door. At the foot of the circular staircase Mr. Winters was still asleep. Hardly able to stand, I crept back to my room. The door into Gertrude's room was no longer locked: she was sleeping like a tired child. And in my dressing-room Liddy hugged a cold hot-water bottle, and mumbled in her sleep.

"There's some things you can't hold with hand cuffs," she was muttering thickly.

CHAPTER XXIX

A Sc.r.a.p OF PAPER

For the first time in twenty years, I kept my bed that day. Liddy was alarmed to the point of hysteria, and sent for Doctor Stewart just after breakfast. Gertrude spent the morning with me, reading something-I forget what. I was too busy with my thoughts to listen. I had said nothing to the two detectives. If Mr. Jamieson had been there, I should have told him everything, but I could not go to these strange men and tell them my niece had been missing in the middle of the night; that she had not gone to bed at all; that while I was searching for her through the house, I had met a stranger who, when I fainted, had carried me into a room and left me there, to get better or not, as it might happen.

The whole situation was terrible: had the issues been less vital, it would have been absurd. Here we were, guarded day and night by private detectives, with an extra man to watch the grounds, and yet we might as well have lived in a j.a.panese paper house, for all the protection we had.

And there was something else: the man I had met in the darkness had been even more startled than I, and about his voice, when he muttered his m.u.f.fled exclamation, there was something vaguely familiar. All that morning, while Gertrude read aloud, and Liddy watched for the doctor, I was puzzling over that voice, without result.

And there were other things, too. I wondered what Gertrude's absence from her room had to do with it all, or if it had any connection. I tried to think that she had heard the rapping noises before I did and gone to investigate, but I'm afraid I was a moral coward that day. I could not ask her.

Perhaps the diversion was good for me. It took my mind from Halsey, and the story we had heard the night before. The day, however, was a long vigil, with every ring of the telephone full of possibilities. Doctor Walker came up, some time just after luncheon, and asked for me.

"Go down and see him," I instructed Gertrude. "Tell him I am out-for mercy's sake don't say I'm sick. Find out what he wants, and from this time on, instruct the servants that he is not to be admitted. I loathe that man."

Gertrude came back very soon, her face rather flushed.

"He came to ask us to get out," she said, picking up her book with a jerk. "He says Louise Armstrong wants to come here, now that she is recovering."

"And what did you say?"

"I said we were very sorry we could not leave, but we would be delighted to have Louise come up here with us. He looked daggers at me. And he wanted to know if we would recommend Eliza as a cook. He has brought a patient, a man, out from town, and is increasing his establishment-that's the way he put it."

"I wish him joy of Eliza," I said tartly. "Did he ask for Halsey?"

"Yes. I told him that we were on the track last night, and that it was only a question of time. He said he was glad, although he didn't appear to be, but he said not to be too sanguine."

"Do you know what I believe?" I asked. "I believe, as firmly as I believe anything, that Doctor Walker knows something about Halsey, and that he could put his finger on him, if he wanted to."

There were several things that day that bewildered me. About three o'clock Mr. Jamieson telephoned from the Casanova station and Warner went down to meet him. I got up and dressed hastily, and the detective was shown up to my sitting-room.

"No news?" I asked, as he entered. He tried to look encouraging, without success. I noticed that he looked tired and dusty, and, although he was ordinarily impeccable in his appearance, it was clear that he was at least two days from a razor.

"It won't be long now, Miss Innes," he said. "I have come out here on a peculiar errand, which I will tell you about later. First, I want to ask some questions. Did any one come out here yesterday to repair the telephone, and examine the wires on the roof?"

"Yes," I said promptly; "but it was not the telephone. He said the wiring might have caused the fire at the stable. I went up with him myself, but he only looked around."

Mr. Jamieson smiled.

"Good for you!" he applauded. "Don't allow any one in the house that you don't trust, and don't trust anybody. All are not electricians who wear rubber gloves."

He refused to explain further, but he got a slip of paper out of his pocketbook and opened it carefully.

"Listen," he said. "You heard this before and scoffed. In the light of recent developments I want you to read it again. You are a clever woman, Miss Innes. Just as surely as I sit here, there is something in this house that is wanted very anxiously by a number of people. The lines are closing up, Miss Innes."

The paper was the one he had found among Arnold Armstrong's effects, and I read it again:

"--by altering the plans for--rooms, may be possible. The best way, in my opinion, would be to--the plan for--in one of the--rooms--chimney."

"I think I understand," I said slowly. "Some one is searching for the secret room, and the invaders-"

"And the holes in the plaster-"

"Have been in the progress of his-"
