It was a strange interview, and one which in the light of after events I recognized to possess extraordinary significance. That sixth sense of Harley’s was awake, was prompting him, but to what extent he understood its promptings at that hour I did not know, and have never known to this day. Intuitively, I believe, as he sat there staring at Colonel Menendez, he began to perceive the shadow within a shadow which was the secret of Cray’s Folly, which was the thing called Bat Wing, which was the devilish force at that very hour alive and potent in our midst. CHAPTER IX OBEAH This conversation in Colonel Menendez’s study produced a very unpleasant impression upon my mind. The atmosphere of Cray’s Folly seemed to become charged with unrest. Of Madame de Stämer and Miss Beverley I saw nothing up to the time that I retired to dress. Having dressed I walked into Harley’s room, anxious to learn if he had formed any theory to account for the singular business which had brought us to Surrey. Harley had excused himself directly we had left the study, stating that he wished to get to the village post-office in time to send a telegram to London. Our host had suggested a messenger, but this, as well as the offer of a car, Harley had declined, saying that the exercise would aid reflection. Nevertheless, I was surprised to find his room empty, for I could not imagine why the sending of a telegram should have detained him so long. Dusk was falling, and viewed from the open window the Tudor garden below looked very beautiful, part of it lying in a sort of purplish shadow and the rest being mystically lighted as though viewed through a golden veil. To the whole picture a sort of magic quality was added by a speck of high-light which rested upon the face of the old sun-dial. I thought that here was a fit illustration for a fairy tale; then I remembered the Colonel’s account of how he had awakened in the act of entering this romantic plaisance, and I was touched anew by an unrestfulness, by a sense of the uncanny. I observed a book lying upon the dressing table, and concluding that it was one which Harley had brought with him, I took it up, glancing at the title. It was “Negro Magic,” and switching on the light, for there was a private electric plant in Cray’s Folly, I opened the book at random and began to read.
