"'There is one thing I'm resolved to do, however,' I continued to myself, as I settled down with paper, pens, and ink at the table in the window. 'I'll buttonhole Birchmore this very afternoon, and get out of him everything he knows about his precious valet. It can do no harm to have the matter cleared up. The thing is absurd, of course; still, the situation out here is rather lonely; and with two such lovely neighbours as Papa Rudolph and Slurk--_par nobile fratrum_--it may be as well to be on the safe side. Yes, that shall be cleared up to-day!' "Having arrived at this sapient determination, I set to work writing my letters, and scribbled away diligently for an hour or two. At length, as I was looking vacantly up from my paper, at a loss for something interesting to set down upon it, my eyes happened to rest upon the pane of my open window. "Like nearly all German windows, it opened inwards on hinges, instead of running up and down in grooves. The pane on my left, therefore, having the dark room as a background, acted as a mirror of the sunlit landscape outside on the right, showing me a portion thereof which was directly invisible to me from where I sat, and to any person standing in which I must myself be invisible. "Now my window was on the southern side of the house, which fronted westward on the road. On the opposite side of the road was a narrow strip of land planted with vegetables, and above this rose the abrupt side of a hill, ascended by a winding path partly hidden by the trees. I could not see this hill and path without leaning out of the window and looking towards the right; but a considerable part of it was reflected in my window-pane mirror, and could thus be readily observed without rising from my chair. Happening, then, as I said, to cast my eyes upon this mirror, I saw two persons standing together on the path upon the hillside, and conversing in a very animated manner. "I had no difficulty in recognising them: they were Mr. Birchmore and his valet. So far there was nothing surprising in the spectacle. That which did surprise and even astonish me, however, was the mutual bearing of the two men towards each other.
