"O Aunt Ray! Aunt Ray!" she cried hysterically. "Some one has been killed, killed!"

"Thieves," I said shortly. "Thank goodness, there are some men in the house to-night." I was getting into my slippers and a bath-robe, and Gertrude with shaking hands was lighting a lamp. Then we opened the door into the hall, where, crowded on the upper landing of the stairs, the maids, white-faced and trembling, were peering down, headed by Liddy. I was greeted by a series of low screams and questions, and I tried to quiet them.

Gertrude had dropped on a chair and sat there limp and shivering.

I went at once across the hall to Halsey's room and knocked; then I pushed the door open. It was empty; the bed had not been occupied!

"He must be in Mr. Bailey's room," I said excitedly, and followed by Liddy, we went there. Like Halsey's, it had not been occupied! Gertrude was on her feet now, but she leaned against the door for support.

"They have been killed!" she gasped. Then she caught me by the arm and dragged me toward the stairs. "They may only be hurt, and we must find them," she said, her eyes dilated with excitement.

I don't remember how we got down the stairs: I do remember expecting every moment to be killed. The cook was at the telephone up-stairs, calling the Greenwood Club, and Liddy was behind me, afraid to come and not daring to stay behind. We found the living-room and the drawing-room undisturbed. Somehow I felt that whatever we found would be in the card-room or on the staircase, and nothing but the fear that Halsey was in danger drove me on; with every step my knees seemed to give way under me. Gertrude was ahead and in the card-room she stopped, holding her candle high. Then she pointed silently to the doorway into the hall beyond. Huddled there on the floor, face down, with his arms extended, was a man.

Gertrude ran forward with a gasping sob. "Jack," she cried, "oh, Jack!"

Liddy had run, screaming, and the two of us were there alone. It was Gertrude who turned him over, finally, until we could see his white face, and then she drew a deep breath and dropped limply to her knees. It was the body of a man, a gentleman, in a dinner coat and white waistcoat, stained now with blood-the body of a man I had never seen before.

CHAPTER IV

WHERE IS HALSEY?

Gertrude gazed at the face in a kind of fascination. Then she put out her hands blindly, and I thought she was going to faint.

"He has killed him!" she muttered almost inarticulately; and at that, because my nerves were going, I gave her a good shake.

"What do you mean?" I said frantically. There was a depth of grief and conviction in her tone that was worse than anything she could have said. The shake braced her, anyhow, and she seemed to pull herself together. But not another word would she say: she stood gazing down at that gruesome figure on the floor, while Liddy, ashamed of her flight and afraid to come back alone, drove before her three terrified women-servants into the drawing-room, which was as near as any of them would venture.

Once in the drawing-room, Gertrude collapsed and went from one fainting spell into another. I had all I could do to keep Liddy from drowning her with cold water, and the maids huddled in a corner, as much use as so many sheep. In a short time, although it seemed hours, a car came rushing up, and Anne Watson, who had waited to dress, opened the door. Three men from the Greenwood Club, in all kinds of costumes, hurried in. I recognized a Mr. Jarvis, but the others were strangers.

"What's wrong?" the Jarvis man asked-and we made a strange picture, no doubt. "n.o.body hurt, is there?" He was looking at Gertrude.

"Worse than that, Mr. Jarvis," I said. "I think it is murder."

At the word there was a commotion. The cook began to cry, and Mrs. Watson knocked over a chair. The men were visibly impressed.

"Not any member of the family?" Mr. Jarvis asked, when he had got his breath.

"No," I said; and motioning Liddy to look after Gertrude, I led the way with a lamp to the card-room door. One of the men gave an exclamation, and they all hurried across the room. Mr. Jarvis took the lamp from me-I remember that-and then, feeling myself getting dizzy and light-headed, I closed my eyes. When I opened them their brief examination was over, and Mr. Jarvis was trying to put me in a chair.

"You must get up-stairs," he said firmly, "you and Miss Gertrude, too. This has been a terrible shock. In his own home, too."

I stared at him without comprehension. "Who is it?" I asked with difficulty. There was a band drawn tight around my throat.

"It is Arnold Armstrong," he said, looking at me oddly, "and he has been murdered in his father's house."

After a minute I gathered myself together and Mr. Jarvis helped me into the living-room. Liddy had got Gertrude up-stairs, and the two strange men from the club stayed with the body. The reaction from the shock and strain was tremendous: I was collapsed-and then Mr. Jarvis asked me a question that brought back my wandering faculties.

"Where is Halsey?" he asked.

"Halsey!" Suddenly Gertrude's stricken face rose before me the empty rooms up-stairs. Where was Halsey?

"He was here, wasn't he?" Mr. Jarvis persisted. "He stopped at the club on his way over."

"I-don't know where he is," I said feebly.

One of the men from the club came in, asked for the telephone, and I could hear him excitedly talking, saying something about coroners and detectives. Mr. Jarvis leaned over to me.

"Why don't you trust me, Miss Innes?" he said. "If I can do anything I will. But tell me the whole thing."

I did, finally, from the beginning, and when I told of Jack Bailey's being in the house that night, he gave a long whistle.

"I wish they were both here," he said when I finished. "Whatever mad prank took them away, it would look better if they were here. Especially-"

"Especially what?"

"Especially since Jack Bailey and Arnold Armstrong were notoriously bad friends. It was Bailey who got Arnold into trouble last spring-something about the bank. And then, too-"

"Go on," I said. "If there is anything more, I ought to know."

"There's nothing more," he said evasively. "There's just one thing we may bank on, Miss Innes. Any court in the country will acquit a man who kills an intruder in his house, at night. If Halsey-"

"Why, you don't think Halsey did it!" I exclaimed. There was a queer feeling of physical nausea coming over me.

"No, no, not at all," he said with forced cheerfulness. "Come, Miss Innes, you're a ghost of yourself and I am going to help you up-stairs and call your maid. This has been too much for you."

Liddy helped me back to bed, and under the impression that I was in danger of freezing to death, put a hot-water bottle over my heart and another at my feet. Then she left me. It was early dawn now, and from voices under my window I surmised that Mr. Jarvis and his companions were searching the grounds. As for me, I lay in bed, with every faculty awake. Where had Halsey gone? How had he gone, and when? Before the murder, no doubt, but who would believe that? If either he or Jack Bailey had heard an intruder in the house and shot him-as they might have been justified in doing-why had they run away? The whole thing was unheard of, outrageous, and-impossible to ignore.

About six o'clock Gertrude came in. She was fully dressed, and I sat up nervously.

"Poor Aunty!" she said. "What a shocking night you have had!" She came over and sat down on the bed, and I saw she looked very tired and worn.

"Is there anything new?" I asked anxiously.

"Nothing. The car is gone, but Warner"-he is the chauffeur-"Warner is at the lodge and knows nothing about it."

"Well," I said, "if I ever get my hands on Halsey Innes, I shall not let go until I have told him a few things. When we get this cleared up, I am going back to the city to be quiet. One more night like the last two will end me. The peace of the country-fiddle sticks!"

Whereupon I told Gertrude of the noises the night before, and the figure on the veranda in the east wing. As an afterthought I brought out the pearl cuff-link.

"I have no doubt now," I said, "that it was Arnold Armstrong the night before last, too. He had a key, no doubt, but why he should steal into his father's house I can not imagine. He could have come with my permission, easily enough. Anyhow, whoever it was that night, left this little souvenir."

Gertrude took one look at the cuff-link, and went as white as the pearls in it; she clutched at the foot of the bed, and stood staring. As for me, I was quite as astonished as she was.

"Where did-you-find it?" she asked finally, with a desperate effort at calm. And while I told her she stood looking out of the window with a look I could not fathom on her face. It was a relief when Mrs. Watson tapped at the door and brought me some tea and toast. The cook was in bed, completely demoralized, she reported, and Liddy, brave with the daylight, was looking for footprints around the house. Mrs. Watson herself was a wreck; she was blue-white around the lips, and she had one hand tied up.

She said she had fallen down-stairs in her excitement. It was natural, of course, that the thing would shock her, having been the Armstrongs' housekeeper for several years, and knowing Mr. Arnold well.
