The parlourmaid pointed to an oblong patch of moonlight on the wall of the passage. The night was cloudless, and the full moon shone slanting in through the dormer and painted a brilliant silver strip on the wall opposite. The window being on the side of the roof to the east, we could not see that, but did see the light thrown through it against the wall. This patch of reflected light was about seven feet above the floor. The window itself was some ten feet up, and the passage was but four feet wide. I enter into these particulars for reasons that will presently appear. The window was divided into three parts by wooden mullions, and was composed of four panes of glass in each compartment. Now I could distinctly see the reflection of the moon through the window with the black bars up and down, and the division of the panes. But I saw more than that: I saw the shadow of a lean arm with a hand and thin, lengthy fingers across a portion of the window, apparently groping at where was the latch by which the casement could be opened. My impression at the moment was that there was a burglar on the leads trying to enter the house by means of this dormer. Without a minute's hesitation I ran into the passage and looked up at the window, but could see only a portion of it, as in shape it was low, though broad, and, as already stated, was set at a great height. But at that moment something fluttered past it, like a rush of flapping draperies obscuring the light. I had placed the ladder, which I found hooked up to the wall, in position, and planted my foot on the lowest rung, when my wife arrived. She had been alarmed by the housemaid, and now she clung to me, and protested that I was not to ascend without my pistol. To satisfy her I got my Colt's revolver that I always kept loaded, and then, but only hesitatingly, did she allow me to mount. I ascended to the casement, unhasped it, and looked out. I could see nothing. The ladder was over-short, and it required an effort to heave oneself from it through the casement on to the leads. I am stout, and not so nimble as I was when younger. After one or two efforts, and after presenting from below an appearance that would have provoked laughter at any other time, I succeeded in getting through and upon the leads. I looked up and down the valley--there was absolutely nothing to be seen except an accumulation of leaves carried there from the trees that were shedding their foliage. The situation was vastly puzzling. As far as I could judge there was no way off the roof, no other window opening into the valley; I did not go along upon the leads, as it was night, and moonlight is treacherous. Moreover, I was wholly unacquainted with the arrangement of the roof, and had no wish to risk a fall.
