Denis de Beaulieu walked fast and was soon knocking at his friend's door; but though he promised himself to stay only a little while and make an early return, his welcome was so pleasant, and he found so much to delay him, that it was already long past midnight before he said good-by upon the threshold. The wind had fallen again in the meanwhile; the night was as black as the grave; not a star, nor a glimmer of moonshine, slipped through the canopy of cloud. Denis was ill-acquainted with the intricate lanes of Chateau Landon; even by daylight he had found some trouble in picking his way; and in this absolute darkness he soon lost it altogether. He was certain of one thing only--to keep mounting the hill; for his friend's house lay at the lower end, or tail, of Chateau Landon, while the inn was up at the head, under the great church spire. With this clew to go upon he stumbled and groped forward, now breathing more freely in the open places where there was a good slice of sky overhead, now feeling along the wall in stifling closes. It is an eerie and mysterious position to be thus submerged in opaque blackness in an almost unknown town. The silence is terrifying in its possibilities. The touch of cold window bars to the exploring hand startles the man like the touch of a toad; the inequalities of the pavement shake his heart into his mouth; a piece of denser darkness threatens an ambuscade or a chasm in the pathway; and where the air is brighter, the houses put on strange and bewildering appearances, as if to lead him further from his way. For Denis, who had to regain his inn without attracting notice, there was real danger as well as mere discomfort in the walk; and he went warily and boldly at once, and at every corner paused to make an observation.
