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. About half-way down a wild glen there stood a small clump of gnarled and stunted oak trees. From behind these, a thin dark column of smoke rose into the still evening air. Clearly this marked the position of my neighbour's house. Trending away to the left, I was able to gain the shelter of a line of rocks, and so reach a spot from which I could command a view of the building without exposing myself to any risk of being observed. It was a small, slate-covered cottage, hardly larger than the boulders among which it lay. Like my own cabin, it showed signs of having been constructed for the use of some shepherd; but, unlike mine, no pains had been taken by the tenants to improve and enlarge it. Two little peeping windows, a cracked and weather-beaten door, and a discoloured barrel for catching the rain water, were the only external objects from which I might draw deductions as to the dwellers within. Yet even in these there was food for thought, for as I drew nearer, still concealing myself behind the ridge, I saw that thick bars of iron covered the windows, while the old door was slashed and plated with the same metal. These strange precautions, together with the wild surroundings and unbroken solitude, gave an indescribably ill omen and fearsome character to the solitary building. Thrusting my pipe into my pocket, I crawled upon my hands and knees through the gorse and ferns until I was within a hundred yards of my neighbour's door. There, finding that I could not approach nearer without fear of detection, I crouched down, and set myself to watch.
