"Very well," I answered. "You need not mention my inquiry."

I gave the boy half-a-crown, and ascended once more to my room. I was feeling a little more awake, but, incomprehensible though it might seem, I began to have a curious idea concerning the coffee with which Louis had served me. I even remembered—or thought that I remembered—some curious taste about it. Yet what object could Louis have in drugging me just as I was on the point of entering into an enterprise on his behalf?

I had a spirit-lamp in my room, and I made myself rapidly a cup of strong tea. Even after I had drunk it, I still felt the remains of the drowsy feeling hanging around me. It was now ten minutes to eleven, and I opened my wardrobe to find the only weapon with which I proposed to arm myself,—a heavily loaded Malacca cane, which had more than once done me good service. To my surprise it was not in its accustomed corner. I was perfectly certain that I had seen it since my return from Paris, and I proceeded to make a thoroughly methodical search. I left scarcely an inch of space in my rooms undisturbed. At last I was forced to come to the conclusion that the stick had gone. Either the valet or some one else must have borrowed it.

It was eleven o'clock by the time I had concluded my search, and there was no time for me to make any further inquiries. I locked up my rooms and descended to the fifth floor. The corridor was empty, and with the key which Louis had given me I opened the door of Mr. Delora's bedroom without difficulty. The room was in darkness, but the electric-light knob was against the wall. I turned it on quickly. There was neither any one in the room, nor any evidence of it having been recently occupied t satisfied with my first inspection, I looked into the wardrobe and lifted the curtains of the bed. Very soon I was assured that there was no one in hiding. I sat down on the edge of the bed and began to consider how to pass the time for the next hour or so. The whiskey and soda set out upon the table attracted my attention. I went over to it, struck by a sudden thought! First I poured out a little of the whiskey. It smelt harmless enough. I tried it upon my tongue. There was no distinctive flavor. Then I looked at the soda-water syphon. The top was screwed up tightly enough, and it easily came undone with the application of a little force. I examined the screw. I felt certain at once, for some reason or other, that it had been tampered with recently. I poured a little of the soda-water into a glass. It was quite flat, and when I tasted it it had a peculiar flavor. Something seemed to have been added to it which destroyed altogether its buoyancy. I screwed on the top again and whistled softly to myself. The whiskey and soda had been placed there by Louis. He had even gone so far as to call my particular attention to it. The coffee which I had drunk a little before had also been prepared by Louis. He was evidently taking no chances! It was his intention that I should be asleep when the intruder, whoever he might be, should enter the room. After all, it seemed that I was in for something a little more complicated in the way of adventures than I had imagined. I examined the lock of the door by which I had entered. It worked easily, and there was also a bolt on the inside. The door was by its side which led into the sitting-room. I also examined it, and I saw with satisfaction that there was at the top a narrow glass transept, which I carefully opened. The sitting-room was in darkness, so Felicia had evidently retired for the night. I sat down to wait!

The time dragged on slowly enough, as it might well have done under the circumstances. I was waiting for something,—I had not the least idea what, or in what form it would arrive. I heard the quarters chime one after the other until one o'clock. Then at last I heard the sound of a key in the outer door of the suite. I had already poured half the syphon of soda and a fair quantity of the whiskey out of the window. I now threw myself upon the bed, closed my eyes, and did my best to simulate a heavy sleep. The person who entered the apartments came up the little outer passage until he reached the door leading into my room. I heard that softly opened. Then there was a pause, broken only by my heavy breathing. Some one was in the room, and it was some one who had learned the art of absolute noiselessness. I heard no footsteps,—not even a man's breathing. Suddenly there was the click of the electric light, and although I still heard nothing, I felt that some one had approached a little way towards the bed. I dared not open my eyes, but in a restless movement, which I felt I might safely make, I raised my hand to shield me, and caught a momentary glimpse of the person who was standing between me and the door. As I expected, it was Louis! He held the soda-water syphon in his hand, as though measuring its contents. I believe that he afterwards came and stood over me. I dared not open my eyes again, for I was none too good an actor, and I feared that he might not be deceived. The quantity of whiskey and soda, however, which I had apparently drunk, must have satisfied him, for he only stayed altogether about a minute in the room. Then he passed out into the sitting-room, closing the door behind him, and without noticing the open transept. I lay quite still, expecting that before long he would return. There were no signs of his coming, however, though through the transept I could see that the light in the sitting-room had been turned on. I rose softly from the bed and bolted both doors. If Louis were to make up his mind to return, it was better, after all, for him to discover that I had been deceiving him than to have him come upon me unawares!

From the top of a chair I was easily able to see through the transept into the sitting-room. At my first glance I thought that it was empty. Then, however, I saw Louis come in from the outer hall, as though from the door of Felicia's room. He came into the centre of the sitting-room and stood there waiting. He was in dark morning clothes, and there was no sign of that charming expression which his patrons found so attractive. His brows were contracted. His mouth seemed screwed together. His peculiar-colored eyes shone like gimlets. He seemed to be waiting impatiently—waiting for what? Once he moved a little, and glanced expectantly toward the open door of the sitting-room. For the first time a horrible fear gripped me. I could scarcely stand in my place. With both hands I held the cornice. My heart began to thump against my ribs. If it should be true! Then all of a sudden a little cry came to my lips, which Heaven knows how I stifled! My eyes were suddenly hot. There was a mist before them. I could see nothing, nothing save Felicia, who had entered the room in a dressing-jacket, with her hair still down her back. It was nothing to me, at that moment, that her eyes were round with fear, that she came as one comes who obeys the call of her master. I was so furious with anger that I had hard work to battle with the impulse which prompted me to throw open the door and confront them both.

"Louis, is this wise?" she murmured.

"There are times," he answered softly, "when one has to dare everything! Listen, Felicia."

"Yes?" she murmured.

"In a short time you will hear a soft knocking on the outside door. Take no notice. I shall open it. It will be some one to see your uncle. We shall talk in this sitting-room. I hope that nothing will happen, but if you hear the sound of blows or voices take no notice. Remain in your room till everything is quiet. Presently, if all is well, I shall knock three times on your door. I may need your help."
