"Keep it bolted, then," he said. "The fell is a strange place. You never know who may be about. It is as well to be on the safe side. Good-bye." He raised his hat, turned on his heel and lounged away along the bank of the little stream. I was still standing with my hand upon the latch, gazing after my unexpected visitor, when I became aware of yet another dweller in the wilderness. Some distance along the path which the stranger was taking there lay a great grey boulder, and leaning against this was a small, wizened man, who stood erect as the other approached, and advanced to meet him. The two talked for a minute or more, the taller man nodding his head frequently in my direction, as though describing what had passed between us. Then they walked on together, and disappeared in a dip of the fell. Presently I saw them ascending once more some rising ground farther on. My acquaintance had thrown his arm round his elderly friend, either from affection or from a desire to aid him up the steep incline. The square burly figure and its shrivelled, meagre companion stood out against the sky-line, and turning their faces, they looked back at me. At the sight, I slammed the door, lest they should be encouraged to return. But when I peeped from the window some minutes afterward, I perceived that they were gone. All day I bent over the Egyptian papyrus upon which I was engaged; but neither the subtle reasonings of the ancient philosopher of Memphis, nor the mystic meaning which lay in his pages, could raise my mind from the things of earth. Evening was drawing in before I threw my work aside in despair. My heart was bitter against this man for his intrusion. Standing by the beck which purled past the door of my cabin, I cooled my heated brow, and thought the matter over. Clearly it was the small mystery hanging over these neighbours of mine which had caused my mind to run so persistently on them. That cleared up, they would no longer cause an obstacle to my studies. What was to hinder me, then, from walking in the direction of their dwelling, and observing for myself, without permitting them to suspect my presence, what manner of men they might be? Doubtless, their mode of life would be found to admit of some simple and prosaic explanation. In any case, the evening was fine, and a walk would be bracing for mind and body. Lighting my pipe, I set off over the moors in the direction which they had taken.
