As I passed by a low ruined wall in the fog, I heard a click as of some iron latch falling to, or flung to carelessly. This drew my attention that way, and then a swish like the swing of a heavy cloak followed, and then I saw a tall man coming from an angle in the wall that had a roof to it. At the moment I was walking rather fast, and if I had continued at that pace, my elbow and the stranger's might have struck one another; for he was also walking fast, and his course--to use one of Slemmick's words--was "slantindicular" to mine. He had not yet descried me, by reason of the wall, and feeling that he had no right on these premises, I drew back, and let him get in front of me. For I was never at all comfortable about things here, since my interview with Nicolo. Keeping my distance carefully, I followed that man towards the buildings, while I tried to make out enough of him to learn his rank and age, and anything else that could be known. If he were to turn and resent my vigilance, gladly would I have it out with him; for a little fight, even if I got the worst of it, would have been a comfort to my bruised spirit then. But the fellow never turned, and seemed to be quite indifferent whether there was any one to heed him. As for his appearance, I could make out very little, except that he was not an Englishman. Dark as it was, I could have sworn to that; whether by his walk, or dress, or figure, or what else, I cannot say; but at any rate he was a foreigner; and I could almost answer for it that on his hip was swung a sword, which would have made short work of me, had he been so desirous. Instead of entering the passage of grey flint which led to the households of the colony, the man I was following turned to the right, where the wall curved in towards the upper door. _Kuban_ and _Orla_, who dwelled for the best of their time in this part of the premises, came forth and looked at him without a single sniff; and then lowered their tails, and crawled away. "What a villain he must be!" thought I; "they know him, but would rather not even speak to him." But the impression he had made upon them was far beyond this. To my surprise, they condemned the entire human race for the moment, reasoning (as we must have taught them to do) from the particular to the universal. For when I passed and held out my hand, not a word would they have to say to me, which perhaps was the better for my safety. Then as I followed with my temper rising, and resolved to bring the man to book as he unbarred the door, what did he do but with one great vault gain that coign of reconnaissance where the watch-dog loved to sit, and plunge from it into the world beyond, with some strange headgear shown between the battlements, and then a clank of hard metal, and a heavy flap of ivy.
