him.
"It was very dark everywhere, but, of course, I knew my way. I felt along for the stair-rail, and went down as quickly as I could. The knocking had stopped, and I was afraid I was too late. I got to the foot of the staircase and over to the door on to the east veranda. I had never thought of anything but that it was Arnold, until I reached the door. It was unlocked and opened about an inch. Everything was black: it was perfectly dark outside. I felt very queer and shaky. Then I thought perhaps Arnold had used his key; he did—strange things sometimes, and I turned around. Just as I reached the foot of the staircase I thought I heard some one coming. My nerves were going anyhow, there in the dark, and I could scarcely stand. I got up as far as the third or fourth step; then I felt that some one was coming toward me on the staircase. The next instant a hand met mine on the stair-rail. Some one brushed past me, and I screamed. Then I must have fainted."
That was Louise's story. There could be no doubt of its truth, and the thing that made it inexpressibly awful to me was that the poor girl had crept down to answer the summons of a brother who would never need her kindly offices again. Twice now, without apparent cause, some one had entered the house by means of the east entrance: had apparently gone his way unhindered through the house, and gone out again as he had entered. Had this unknown visitor been there a third time, the night Arnold Armstrong was murdered? Or a fourth, the time Mr. Jamieson had locked some one in the clothes chute?
Sleep was impossible, I think, for any of us. We dispersed finally to bathe and dress, leaving Louise little the worse for her experience. But I determined that before the day was over she must know the true state of affairs. Another decision I made, and I put it into execution immediately after breakfast. I had one of the unused bedrooms in the east wing, back along the small corridor, prepared for occupancy, and from that time on, Alex, the gardener, slept there. One man in that barn of a house was an absurdity, with things happening all the time, and I must say that Alex was as unobjectionable as any one could possibly have been.
The next morning, also, Halsey and I made an exhaustive examination of the circular staircase, the small entry at its foot, and the card-room opening from it. There was no evidence of anything unusual the night before, and had we not ourselves heard the rapping noises, I should have felt that Louise's imagination had run away with her. The outer door was closed and locked, and the staircase curved above us, for all the world like any other staircase.
Halsey, who had never taken seriously my account of the night Liddy and I were there alone, was grave enough now. He examined the paneling of the wainscoting above and below the stairs, evidently looking for a secret door, and suddenly there flashed into my mind the recollection of a scrap of paper that Mr. Jamieson had found among Arnold Armstrong's effects. As nearly as possible I repeated its contents to him, while Halsey took them down in a note-book.
"I wish you had told me that before," he said, as he put the memorandum carefully away. We found nothing at all in the house, and I expected little from any examination of the porch and grounds. But as we opened the outer door something fell into the entry with a clatter. It was a cue from the billiard-room.
Halsey picked it up with an exclamation.
"That's careless enough," he said. "Some of the servants have been amusing themselves."
I was far from convinced. Not one of the servants would go into that wing at night unless driven by dire necessity. And a billiard cue! As a weapon of either offense or defense it was an absurdity, unless one accepted Liddy's hypothesis of a ghost, and even then, as Halsey pointed out, a billiard-playing ghost would be a very modern evolution of an ancient institution.
That afternoon we, Gertrude, Halsey and I, attended the coroner's inquest in town. Doctor Stewart had been summoned also, it transpiring that in that early Sunday morning, when Gertrude and I had gone to our rooms, he had been called to view the body. We went, the four of us, in the machine, preferring the execrable roads to the matinee train, with half of Casanova staring at us. And on the way we decided to say nothing of Louise and her interview with her stepbrother the night he died. The girl was in trouble enough as it was.
A Hint of Scandal
In giving the gist of what happened at the inquest, I have only one excuse—to recall to the reader the events of the night of Arnold Armstrong's murder. Many things had occurred which were not brought out at the inquest and some things were told there that were new to me. Altogether, it was a gloomy affair, and the six men in the corner, who constituted the coroner's jury, were evidently the merest puppets in the hands of that all-powerful gentleman, the coroner.
Gertrude and I sat well back, with our veils down. There were a number of people I knew: Barbara Fitzhugh, in extravagant mourning—she always went into black on the slightest provocation, because it was becoming—and Mr. Jarvis, the man who had come over from the Greenwood Club the night of the murder. Mr. Harton was there, too, looking impatient as the inquest dragged, but alive to every particle of evidence. From a corner Mr. Jamieson was watching the proceedings intently.
Doctor Stewart was called first. His evidence was told briefly, and amounted to this: on the Sunday morning previous, at a quarter before five, he had been called to the telephone. The message was from a Mr. Jarvis, who asked him to come at once to Sunnyside, as there had been an accident there, and Mr. Arnold Armstrong had been shot. He had dressed hastily, gathered up some instruments, and driven to Sunnyside.
He was met by Mr. Jarvis, who took him at once to the east wing. There, just as he had fallen, was the body of Arnold Armstrong. There was no need of the instruments: the man was dead. In answer to the coroner's question—no, the body had not been moved, save to turn it over. It lay at the foot of the circular staircase. Yes, he believed death had been instantaneous. The body was still somewhat warm and rigor mortis had not set in. It occurred late in cases of sudden death. No, he believed the probability of suicide might be eliminated; the wounds could have been self-inflicted, but with difficulty, and there had been no weapon found.
The doctor's examination was over, but he hesitated and cleared his throat.
"Mr. Coroner," he said, "at the risk of taking up valuable time, I would like to speak of an incident that may or may not throw some light on this matter."
The audience was alert at once.
"Kindly proceed, Doctor," the coroner said.
"My home is in Englewood, two miles from Casanova," the doctor began. "In the absence of Doctor Walker, a number of Casanova people have been consulting me. A month ago—five weeks, to be exact—a woman whom I had never seen came to my office. She was in deep mourning and kept her veil down, and she brought for examination a child, a boy of six. The little fellow was ill; it looked like typhoid, and the mother was frantic. She wanted a permit to admit the youngster to the Children's Hospital in town here, where I am a member of the staff, and I gave her one. The incident would have escaped me, but for a curious thing. Two days before Mr. Armstrong was shot, I was sent for to go to the Country Club: some one had been struck with a golf-ball that had gone wild. It was late when I left—I was on foot, and about a mile from the club, on the Claysburg road, I met two people. They were disputing violently, and I had no difficulty in recognizing Mr. Armstrong. The woman, beyond doubt, was the one who had consulted me about the child."
At this hint of scandal, Mrs. Ogden Fitzhugh sat up very straight. Jamieson was looking slightly skeptical, and the coroner made a note.
"The Children's Hospital, you say, Doctor?" he asked.
"Yes. But
