The "digging out" of the Major did not prove to be an entire success. He was in one of his peculiar moods, which I knew of old, and rather surly, being pointedly rude on more than one occasion to Wales. He had some accounts to look into, or professed to have, and the three of us presently left him alone. It was now about ten o'clock, and Aubrey Wales made his departure, shaking me warmly by the hand and expressing the hope that we should see more of one another. He could not foresee that the wish was to be realised in a curious fashion. Mrs. Dale informed me that the Major in all probability would remain immured in his study until a late hour, which I took to be an intimation that she wished to retire. I therefore pleaded weariness as a result of my journey, and went up to my room, although I had no intention of turning-in. I opened the two windows widely, and the heavy perfume of some kind of tobacco plant growing in the beds below grew almost oppressive. The heat of the night was truly phenomenal; I might have been, not in an English home county, but in the Soudan. An absolute stillness reigned throughout Low Fennel, and, my hearing being peculiarly acute, I could detect the chirping of the bats which flitted restlessly past my windows. It was difficult to decide how to act. My experience of so-called supernatural appearances had strengthened my faith in the theory set forth in the paper "Chemistry of Psychic Phenomena"--which had attracted unexpected attention a year before. Therein I classified hauntings under several heads, basing my conclusions upon the fact that such apparitions are invariably localised; often being confined, not merely to a particular room, for instance, but to a certain wall, door, or window. I had been privileged to visit most of the famous haunted homes of Great Britain, and this paper was the result; but in the case of Low Fennel I found myself nonplussed, largely owing to lack of data. I hoped on the morrow to make certain inquiries along lines suggested by oddities in the structure of the house itself and by the nature of the little valley in which it stood. When meditating I never sit still, and whilst marshalling my ideas I paced the room from end to end, smoking the whole time. Both windows and also the door, were widely opened. The amazing heat-wave which we were then experiencing promised to afford me a valuable clue, for I had proved to my own satisfaction that the apparitions variously known as "controls" and "elementals," not infrequently coincided with abrupt climatic changes, thunder-storms, or heat waves, or with natural phenomena, such as landslides and the like. This pacing led me from end to end of the room, then, between the open door and the large dressing-table facing it. It was as I returned from the door towards the dressing-table that I became aware of the presence of the _contorted face_.
