It was an awfully dark and tempestuous night; the wind howled in fury through the trees, and round the towers; the large drops of rain dashed against the casements, the small lozenges of glass rattled and clattered in their leaden frames, and the thick boards of the oaken floor heaved and shivered under the force of the tempest. From time to time a keen blue streak of lightning crossed the descending deluge, and for an instant the great black masses of the forest, and the high and broken rocks around, appeared like spectres of a gone-by world, and sank into Egyptian darkness again, almost as soon as seen; and then the roar of the thunder was added to the scream of the blast, seeming to shake the whole building to its foundation. In the midst of this storm, and towards one o'clock in the morning, a young man, of about one-and-twenty years of age, took his way silently, and with a stealthy step, through the large old halls and long passages of the castle of Ehrenstein. His dress was that of one moving in the higher ranks of society, but poor for his class; and though the times were unusually peaceful, he wore a heavy sword by his side, and a poniard hanging by a ring from his girdle. Gracefully yet powerfully formed, his frame afforded the promise of great future strength, and his face, frank and handsome without being strictly beautiful, owed perhaps more to the expression than to the features. He carried a small brazen lamp in his hand, and seemed bound upon some grave and important errand, for his countenance was serious and thoughtful, his eyes generally bent down, and his step quick, although, as we have said, light and cautious. The room that he quitted was high up in the building, and, descending by a narrow and steep staircase, formed of large square blocks of oak, with nothing but a rope to steady the steps, he entered a long wide corridor below, flanked on one side by tall windows like those of a church, and on the other by numerous small doors. The darkness was so profound that, at first, the rays of the lamp only served to dissipate the obscurity immediately around it, while the rest of the corridor beyond looked like the mouth of a yawning interminable vault, filled with gloom and shadows. The next moment, however, as he advanced, a blazing sheet of electric flame glanced over the windows, displaying their long line upon the right, and the whole interior of the corridor. Here and there an old suit of armour caught the light, and the grotesque figures on two large antique stone benches seemed to grin and gibber in the flame. Still the young man walked on, pausing only for one moment at a door on the left, and looking up at it with a smile somewhat melancholy. At the end of the corridor, on the left, he came to a larger staircase than that which he had before descended, and going cautiously down, and through some other passages, he found himself in a small vestibule, with two doors on either hand. They were of various dimensions, but all studded with large nails, and secured by thick bands of iron; and turning to the largest of the four, he quietly lifted the latch, and pushed it open. The wind, as he did so, had nearly blown out the lamp, and in suddenly shading it with his hand, he let slip the ponderous mass of woodwork, which was blown back against its lintels with a dull clang, which echoed far away through the vaulted passages of the castle.
