“Good,” he muttered. “I will leave that side of the enquiry in your very capable hands, Knox.” He paused, and began to stare about him. “From this point,” said he, “we have an unobstructed view of the tower.” We turned and stood looking up at the unsightly gray structure, with its geometrical rows of windows and the minaret-like gallery at the top. “Of course”--I broke a silence of some moments duration--“the entire scheme of Cray’s Folly is peculiar, but the rooms, except for a uniformity which is monotonous, and an unimaginative scheme of decoration which makes them all seem alike, are airy and well lighted, eminently sane and substantial. The tower, however, is quite inexcusable, unless the idea was to enable the occupant to look over the tops of the trees in all directions.” “Yes,” agreed Harley, “it is an ugly landmark. But yonder up the slope I can see the corner of what seems to be a very picturesque house of some kind.” “I caught a glimpse of it earlier to-day,” I replied. “Yes, from this point a little more of it is visible. Apparently quite an old place.” I paused, staring up the hillside, but Harley, hands locked behind him and chin lowered reflectively, was pacing on. I joined him, and we proceeded for some little distance in silence, passing a gardener who touched his cap respectfully and to whom I thought at first my companion was about to address some remark. Harley passed on, however, still occupied, it seemed, with his reflections, and coming to a gravel path which, bordering one side of the lawns, led down from terrace to terrace into the valley, turned, and began to descend. “Let us go and interview the swans,” he murmured absently. CHAPTER VII AT THE LAVENDER ARMS In certain moods Paul Harley was impossible as a companion, and I, who knew him well, had learned to leave him to his own devices at such times. These moods invariably corresponded with his meeting some problem to the heart of which the lance of his keen wit failed to penetrate. His humour might not display itself in the spoken word, he merely became oblivious of everything and everybody around him. People might talk to him and he scarce noted their presence, familiar faces appear and he would see them not. Outwardly he remained the observant Harley who could see further into a mystery than any other in England, but his observation was entirely introspective; although he moved amid the hustle of life he was spiritually alone, communing with the solitude which dwells in every man’s heart. Presently, then, as we came to the lake at the foot of the sloping lawns, where water lilies were growing and quite a number of swans had their habitation, I detected the fact that I had ceased to exist so far as Harley was concerned. Knowing this mood of old, I pursued my way alone, pressing on across the valley and making for a swing gate which seemed to open upon a public footpath. Coming to this gate I turned and looked back.
