At a little before eleven o'clock, then, by which time the moon had risen high in the heaven, a rustling and scraping sound might have been heard by any one standing near that wall of the park which separated it from the neighbouring common, and in a moment, after, the head and shoulders of a man appeared above the parapet. He gave a momentary glance into the walk which was immediately contiguous, and then swinging himself over, dropped at once to the ground. Pausing again, he looked round him more carefully; and then gave a low whistle. No one followed, however; and the intruder, who was apparently a lad of eighteen or nineteen, advanced cautiously across the walk, and was soon placed beneath the shadow of the tall elms. Every two or three minutes the lad paused to look around him; but as his eyes were more frequently bent upon the ground than raised, it appeared that he rather feared losing his way than apprehended the appearance of any other person in the place to which he had somewhat furtively introduced himself. Humming a tune as he advanced, he approached that part of the park from which, as we have before said, a view could be obtained both of the mansion and the park-keeper's house; and here, fixing his eyes upon the latter, he seated himself at the foot of a sturdy chestnut-tree at a little distance within the extreme edge of the wood. There was a wreath of white smoke still curling up from the chimney of the peaceful-looking dwelling of the park-keeper; and through two of the cottage casements a full yellow light was streaming, so that it was evident enough that some of the inmates were up and awake. For about half an hour the young man kept his post with perseverance and tranquillity, ceasing to hum the air with which he had amused himself as he came along, and apparently regarding nothing but the cottage of the park-keeper. At the end of that time, however, he rose, muttering, "I'll stay here no longer. I might as well have been with Lena all this while. If Dick would but wait till one o'clock, they would be all abed to a certainty;" and he walked two or three steps resolutely away. Ere he was out of sight, he, nevertheless, turned to look once more. The light was still burning; but as he was in the very act of resuming his retreat, it was totally extinguished, and nothing was to be seen but the dark outline of the cottage in the clear moonlight. He now paused again for a moment or two, to be sure of the facts; and then retracing his way as fast as possible to the particular part of the wall over which he had obtained ingress, he stopped, and whistled louder than before. For some minutes there was no reply, and he then whistled again, which instantly produced a corresponding signal from without, and a voice demanded, "Is all right?"
