As I rose from my chair and came forward, Miss Trelawny raised her eyes toward me. When she saw me she shrieked and started to her feet, pointing towards me. Never shall I forget the strange picture she made, with her white drapery all smeared with blood which, as she rose from the pool, ran in streaks toward her bare feet. I believe that I had only been asleep; that whatever influence had worked on Mr. Trelawny and Nurse Kennedy—and in less degree on Sergeant Daw—had not touched me. The respirator had been of some service, though it had not kept off the tragedy whose dire evidences were before me. I can understand now—I could understand even then—the fright, added to that which had gone before, which my appearance must have evoked. I had still on the respirator, which covered mouth and nose; my hair had been tossed in my sleep. Coming suddenly forward, thus enwrapped and dishevelled, in that horrified crowd, I must have had, in the strange mixture of lights, an extraordinary and terrifying appearance. It was well that I recognised all this in time to avert another catastrophe; for the half-dazed, mechanically-acting Detective put in the cartridges and had raised his revolver to shoot at me when I succeeded in wrenching off the respirator and shouting to him to hold his hand. In this also he acted mechanically; the red, half-awake eyes had not in them even then the intention of conscious action. The danger, however, was averted. The relief of the situation, strangely enough, came in a simple fashion. Mrs. Grant, seeing that her young mistress had on only her nightdress, had gone to fetch a dressing-gown, which she now threw over her. This simple act brought us all back to the region of fact. With a long breath, one and all seemed to devote themselves to the most pressing matter before us, that of staunching the flow of blood from the arm of the wounded man. Even as the thought of action came, I rejoiced; for the bleeding was very proof that Mr. Trelawny still lived.
Last night's lesson was not thrown away. More than one of those present knew now what to do in such an emergency, and within a few seconds willing hands were at work on a tourniquet. A man was at once despatched for the doctor, and several of the servants disappeared to make themselves respectable. We lifted Mr. Trelawny on to the sofa where he had lain yesterday; and, having done what we could for him, turned our attention to the Nurse. In all the turmoil she had not stirred; she sat there as before, erect and rigid, breathing softly and naturally and with a placid smile. As it was manifestly of no use to attempt anything with her till the doctor had come, we began to think of the general situation.
Mrs. Grant had by this time taken her mistress away and changed her clothes; for she was back presently in a dressing-gown and slippers, and with the traces of blood removed from her hands. She was now much calmer, though she trembled sadly; and her face was ghastly white. When she had looked at her father's wrist, I holding the tourniquet, she turned her eyes round the room, resting them now and again on each one of us present in turn, but seeming to find no comfort. It was so apparent to me that she did not know where to begin or whom to trust that, to reassure her, I said:
"I am all right now; I was only asleep." Her voice had a gulp in it as she said in a low voice:
"Asleep! You! and my Father in danger! I thought you were on the watch!" I felt the sting of justice in the reproach; but I really wanted to help her, so I answered:
"Only asleep. It is bad enough, I know; but there is something more than an "only" round us here. Had it not been that I took a definite precaution I might have been like the Nurse there." She turned her eyes swiftly on the weird figure, sitting grimly upright like a painted statue; and then her face softened. With the action of habitual courtesy she said:
"Forgive me! I did not mean to be rude. But I am in such distress and fear that I hardly know what I am saying. Oh, it is dreadful! I fear for fresh trouble and horror and mystery every moment." This cut me to the very heart, and out of the heart's fulness I spoke:
"Don't give me a thought! I don't deserve it. I was on guard, and yet I slept. All that I can say is that I didn't mean to, and I tried to avoid it; but it was over me before I knew it. Anyhow, it is done now; and can't be undone. Probably some day we may understand it all; but now let us try to get at some idea of what has happened. Tell me what you remember!" The effort to recollect seemed to stimulate her; she became calmer as she spoke:
"I was asleep, and woke suddenly with the same horrible feeling on me that Father was in great and immediate danger. I jumped up and ran, just as I was, into his room. It was nearly pitch dark, but as I opened the door there was light enough to see Father's nightdress as he lay on the floor under the safe, just as on that first awful night. Then I think I must have gone mad for a moment." She stopped and shuddered. My eyes lit on Sergeant Daw, still fiddling in an aimless way with the revolver. Mindful of my work with the tourniquet, I said calmly:
"Now tell us, Sergeant Daw, what did you fire at?" The policeman seemed to pull himself together with the habit of obedience. Looking around at the servants remaining in the room, he said with that air of importance which, I take it, is the regulation attitude of an official of the law before strangers:
"Don't you think, sir, that we can allow the servants to go away? We can then better go into the matter." I nodded approval; the servants took the hint and withdrew, though unwillingly, the last one closing the door behind him. Then the Detective went on:
"I think I had better tell you my impressions, sir, rather than recount my actions. That is, so far as I remember them." There was a mortified deference now in his manner, which probably arose from his consciousness of the awkward position in which he found himself. "I went to sleep half-dressed—as I am now, with a revolver under my pillow. It was the last thing I remember thinking of. I do not know how long I slept. I had turned off the electric light, and it was quite dark. I thought I heard a scream; but I can't be sure, for I felt thick-headed as a man does when he is called too soon after an extra long stretch of work. Not that such was the case this time. Anyhow my thoughts flew to the pistol. I took it out, and ran on to the landing. Then I heard a sort of scream, or rather a call for help, and ran into this room. The room was dark, for the lamp beside the Nurse was out, and the only light was that from the landing, coming through the open door. Miss Trelawny was kneeling on the floor beside her father, and was screaming. I thought I saw something move between me and the window; so, without thinking, and being half dazed and only half awake, I shot at it. It moved a little more to the right between the windows, and I shot again. Then you came up out of the big chair with all that muffling on your face. It seemed
