"Doctor Walker," I said, "I have come to you to ask some questions. I hope you will answer them. As you know, my nephew has not yet been found."

"So I understand," stiffly.

"I believe, if you would, you could help us, and that leads to one of my questions. Will you tell me what was the nature of the conversation you held with him the night he was attacked and carried off?"

"Attacked! Carried off!" he said, with pretended surprise. "Really, Miss Innes, don't you think you exaggerate? I understand it is not the first time Mr. Innes has-disappeared."

"You are quibbling, doctor. This is a matter of life and death. Will you answer my question?"

"Certainly. He said his nerves were bad, and I gave him a prescription for them. I am violating professional ethics when I tell you even as much as that."

I could not tell him he lied. I think I looked it. But I hazarded a random shot.

"I thought perhaps," I said, watching him narrowly, "that it might be about-Nina Carrington."

For a moment I thought he was going to strike me. He grew livid, and a small crooked blood-vessel in his temple swelled and throbbed curiously. Then he forced a short laugh.

"Who is Nina Carrington?" he asked.

"I am about to discover that," I replied, and he was quiet at once. It was not difficult to divine that he feared Nina Carrington a good deal more than he did the devil. Our leave-taking was brief; in fact, we merely stared at each other over the waiting-room table, with its litter of year-old magazines. Then I turned and went out.

"To Richfield," I told Warner, and on the way I thought, and thought hard.

"Nina Carrington, Nina Carrington," the roar and rush of the wheels seemed to sing the words. "Nina Carrington, N. C." And I then knew, knew as surely as if I had seen the whole thing. There had been an N. C. on the suit-case belonging to the woman with the pitted face. How simple it all seemed. Mattie Bliss had been Nina Carrington. It was she Warner had heard in the library. It was something she had told Halsey that had taken him frantically to Doctor Walker's office, and from there perhaps to his death. If we could find the woman, we might find what had become of Halsey.

We were almost at Richfield now, so I kept on. My mind was not on my errand there now. It was back with Halsey on that memorable night. What was it he had said to Louise, that had sent her up to Sunnyside, half wild with fear for him? I made up my mind, as the car drew up before the Tate cottage, that I would see Louise if I had to break into the house at night.

Almost exactly the same scene as before greeted my eyes at the cottage. Mrs. Tate, the baby-carriage in the path, the children at the swing-all were the same.

She came forward to meet me, and I noticed that some of the anxious lines had gone out of her face. She looked young, almost pretty.

"I am glad you have come back," she said. "I think I will have to be honest and give you back your money."

"Why?" I asked. "Has the mother come?"

"No, but some one came and paid the boy's board for a month. She talked to him for a long time, but when I asked him afterward he didn't know her name."

"A young woman?"

"Not very young. About forty, I suppose. She was small and fair-haired, just a little bit gray, and very sad. She was in deep mourning, and, I think, when she came, she expected to go at once. But the child, Lucien, interested her. She talked to him for a long time, and, indeed, she looked much happier when she left."

"You are sure this was not the real mother?"

"O mercy, no! Why, she didn't know which of the three was Lucien. I thought perhaps she was a friend of yours, but, of course, I didn't ask."

"She was not-pock-marked?" I asked at a venture. "No, indeed. A skin like a baby's. But perhaps you will know the initials. She gave Lucien a handkerchief and forgot it. It was very fine, black-bordered, and it had three hand-worked letters in the corner-F. B. A."

"No," I said with truth enough, "she is not a friend of mine." F. B. A. was f.a.n.n.y Armstrong, without a chance of doubt!

With another warning to Mrs. Tate as to silence, we started back to Sunnyside. So f.a.n.n.y Armstrong knew of Lucien Wallace, and was sufficiently interested to visit him and pay for his support. Who was the child's mother and where was she? Who was Nina Carrington? Did either of them know where Halsey was or what had happened to him?

On the way home we pa.s.sed the little cemetery where Thomas had been laid to rest. I wondered if Thomas could have helped us to find Halsey, had he lived. Farther along was the more imposing burial-ground, where Arnold Armstrong and his father lay in the shadow of a tall granite shaft. Of the three, I think Thomas was the only one sincerely mourned.

CHAPTER XXVIII

A TRAMP AND THE TOOTHACHE

The bitterness toward the dead president of the Traders' Bank seemed to grow with time. Never popular, his memory was execrated by people who had lost nothing, but who were filled with disgust by constantly hearing new stories of the man's grasping avarice. The Traders' had been a favorite bank for small tradespeople, and in its savings department it had solicited the smallest deposits. People who had thought to be self-supporting to the last found themselves confronting the poorhouse, their two or three hundred dollar savings wiped away. All bank failures have this element, however, and the directors were trying to promise twenty per cent. on deposits.

But, like everything else those days, the bank failure was almost forgotten by Gertrude and myself. We did not mention Jack Bailey: I had found nothing to change my impression of his guilt, and Gertrude knew how I felt. As for the murder of the bank president's son, I was of two minds. One day I thought Gertrude knew or at least suspected that Jack had done it; the next I feared that it had been Gertrude herself, that night alone on the circular staircase. And then the mother of Lucien Wallace would obtrude herself, and an almost equally good case might be made against her. There were times, of course, when I was disposed to throw all those suspicions aside, and fix definitely on the unknown, whoever that might be.

I had my greatest disappointment when it came to tracing Nina Carrington. The woman had gone without leaving a trace. Marked as she was, it should have been easy to follow her, but she was not to be found. A description to one of the detectives, on my arrival at home, had started the ball rolling. But by night she had not been found. I told Gertrude, then, about the telegram to Louise when she had been ill before; about my visit to Doctor Walker, and my suspicions that Mattie Bliss and Nina Carrington were the same. She thought, as I did, that there was little doubt of it.

I said nothing to her, however, of the detective's suspicions about Alex. Little things that I had not noticed at the time now came back to me. I had an uncomfortable feeling that perhaps Alex was a spy, and that by taking him into the house I had played into the enemy's hand. But at eight o'clock that night Alex himself appeared, and with him a strange and repulsive individual. They made a queer pair, for Alex was almost as disreputable as the tramp, and he had a badly swollen eye.

Gertrude had been sitting listlessly waiting for the evening message from Mr. Jamieson, but when the singular pair came in, as they did, without ceremony, she jumped up and stood staring. Winters, the detective who watched the house at night, followed them, and kept his eyes sharply on Alex's prisoner. For that was the situation as it developed.

He was a tall lanky individual, ragged and dirty, and just now he looked both terrified and embarra.s.sed. Alex was too much engrossed to be either, and to this day I don't think I ever asked him why he went off without permission the day before.

"Miss Innes," Alex began abruptly, "this man can tell us something very important about the disappearance of Mr. Innes. I found him trying to sell this watch."

He took a watch from his pocket and put it on the table. It was Halsey's watch. I had given it to him on his twenty-first birthday: I was dumb with apprehension.

"He says he had a pair of cuff-links also, but he sold them-"

"Fer a dollar'n half," put in the disreputable individual hoa.r.s.ely, with an eye on the detective.

"He is not-dead?" I implored. The tramp cleared his throat.

"No'm," he said huskily. "He was used up pretty bad, but he weren't dead. He was comin' to hisself when I"-he stopped and looked at the detective. "I didn't steal it, Mr. Winters," he whined. "I found it in the road, honest to G.o.d, I did."

Mr. Winters paid no attention to him. He was watching Alex.

"I'd better tell what he told me," Alex broke in. "It will be quicker. When Jamieson-when Mr. Jamieson calls up we can start him right. Mr. Winters, I found this man trying to sell that watch on Fifth Street. He offered it to me for three dollars."

"How did you know the watch?" Winters snapped at him.

"I had seen it before, many times. I used it at night when I was watching at the foot of the staircase." The detective was satisfied. "When he offered the watch to me, I knew it, and I pretended I was going to buy it. We went into an alley and I got the watch." The tramp shivered. It was plain how Alex had secured the watch. "Then-I got the story from this fellow. He claims to have seen the whole affair. He says he was in an empty car-in the car the automobile struck."

The tramp broke in here, and told his story, with frequent interpretations by Alex and Mr. Winters. He used a strange medley, in which familiar words took unfamiliar meanings, but it was gradually made clear to us.

On the night in question the tramp had been "pounding his ear"-this stuck to me as being graphic-in an empty box-car along the siding at Casanova. The train was going west, and due to leave at dawn. The tramp and the "brakey" were friendly, and things going well. About ten o'clock, perhaps earlier, a terrific crash against the side of the car roused him. He tried to open the door, but could not move it. He got out of the other side, and just as he did so, he heard some one groan.

The habits of a lifetime made him cautious. He slipped on to the b.u.mper of a car and peered through. An automobile had struck the car, and stood there on two wheels. The tail lights were burning, but the headlights were out. Two men were stooping over some one who lay on the ground. Then the taller of the two started on a dog-trot along the train looking for an empty. He found one four cars away and ran back again. The two lifted the unconscious man into the empty box-car, and, getting in themselves, stayed for three or four minutes. When they came out, after closing the sliding door, they cut up over the railroad embankment toward the town. One, the short one, seemed to limp.
