would have awakened him; as it was, I was possessed with the idea that he ought to know nothing of our suspicions, nothing of the anonymous letter (from us, at least), and in no manner or way be admitted to confidence. Rather hard on Peyton, to be sure; but there was something about him I didn't like, something besides the mere fact that I saw he didn't like me, and——What was that! There could be no mistake! I plainly saw through my open window a sudden gleam of light among the leaves of the oak-tree on the other side of the garden-walk. It was as though the light had been momentarily thrown upon it from a bull's-eye lantern and instantly withdrawn. More than that, the light was thrown upon it from this side. Thoroughly aroused now, I stole noiselessly from the bed; took my revolver; and, making the least possible "creak" in turning the key, I slowly opened my door, and on tiptoe and in stocking feet crept out into the hall. My plan was to go and arouse Harrod. Without closing my door I turned stealthily away; and, as a matter of course, stumbled over one of my boots. There they were, right at the door, just where I had left them, and visible enough for all practical purposes in the dim light that came from my open doorway and the window at the end of the hall. It was clumsy and stupid of me. I looked towards Peyton's door, wondering if the noise, slight as it was, had awakened him. No more snoring, at all events. I took a step or two towards his room to listen, looked carefully down to see that I didn't stumble over his boots too, and then stopped short. Peyton's boots were no longer there. For a moment I could not realize it; then I stole closer to the door, and the door that I knew was tightly closed when I came up-stairs was now unlatched and partly open. The conviction forced itself into my mind that my next-door neighbor was up to some of his old devilment, and that that signal whistle had some connection with the mysterious disappearance of his boots. Peeping through the partly-opened door, I could see the bed, its coverlet undisturbed, its pillows smooth and untouched. That was enough to embolden me, and at the same time make me mad. All that snoring was a counterfeit for my benefit, was it? I opened the door and looked in: no signs of its late occupant; Ned Peyton had gone. Sorely puzzled what to do next, I sidled out again; sneaked out, I might as well say, for that's the way I felt; and leaving his door as I found it, returned to my own room and took post at the window. Curiously enough, the discovery of Peyton's absence and his probable
