"Thus would _I_ die," exclaimed the looker on, exultingly--"thus would I die! Amid a world's agonizing throes, when the mountains seem to bend their scathed tops, and the ocean roars its submission to the storm." As he spoke, he advanced, heedless of the elements, through the casement, and stood upon the extreme edge of the battlemented parapet. A shrill, mocking laugh greeted his concluding words, and a voice, that seemed to his excited imagination preternaturally hollow, exclaimed-- "And die thus you shall!" For a moment he stood perfectly paralyzed; but a heavy hand was laid upon his shoulder, and he turned to meet the glare of two eyes that shone as if lit with fire from hell. The person from whom the glance proceeded held in a threatening position a long, keen-looking dagger, and the blade gleamed brightly in the electric light with which a sudden flash of lightning illumined the scene. The man who had a moment before looked defiantly upon the wrathy heavens shrank from the danger which now threatened him from a human foe. It was, however, but for a moment. He saw in the implacable countenance of the man who had so strangely come upon him, sufficient evidence of some dark and evil purpose to make him look for mischief. He suspected the existence of a danger that would tax his every energy. He turned upon the intruder a look of inquiry, firm and proud, and somewhat rebuking in its aspect. The next moment, however, recollecting that, in the intervals between the flashes, all was invisible, he put the question audibly, which before he had mutely expressed. A tremendous peal of thunder drowned the words in its frightful reverberations, and the lightning that followed showed him the arm of his foe raised to strike. Even as the blade touched his breast he caught his adversary's wrist and threw himself upon him. Powerful he found him beyond all expectations, and his cheek turned ghastly pale, for he felt hope deserting him.
