While Sosia, thus entrapped, was lamenting his fate, and revolving his schemes to repossess himself of Nydia, the blind girl, with that singular precision and dexterous rapidity of motion, which, we have before observed, was peculiar to her, had passed lightly along the peristyle, threaded the opposite passage that led into the garden, and, with a beating heart, was about to proceed towards the gate, when she suddenly heard the sound of approaching steps, and distinguished the dreaded voice of Arbaces himself. She paused for a moment in doubt and terror; then suddenly it flashed across her recollection that there was another passage which was little used except for the admission of the fair partakers of the Egyptian's secret revels, and which wound along the basement of that massive fabric towards a door which also communicated with the garden. By good fortune it might be open. At that thought, she hastily retraced her steps, descended the narrow stairs at the right, and was soon at the entrance of the passage. Alas! the door at the entrance was closed and secured. While she was yet assuring herself that it was indeed locked, she heard behind her the voice of Calenus, and, a moment after, that of Arbaces in low reply. She could not stay there; they were probably passing to that very door. She sprang onward, and felt herself in unknown ground. The air grew damp and chill; this reassured her. She thought she might be among the cellars of the luxurious mansion, or, at least, in some rude spot not likely to be visited by its haughty lord, when again her quick ear caught steps and the sound of voices. On, on, she hurried, extending her arms, which now frequently encountered pillars of thick and massive form. With a tact, doubled in acuteness by her fear, she escaped these perils, and continued her way, the air growing more and more damp as she proceeded; yet, still, as she ever and anon paused for breath, she heard the advancing steps and the indistinct murmur of voices. At length she was abruptly stopped by a wall that seemed the limit of her path. Was there no spot in which she could hide? No aperture? no cavity? There was none! She stopped, and wrung her hands in despair; then again, nerved as the voices neared upon her, she hurried on by the side of the wall; and coming suddenly against one of the sharp buttresses that here and there jutted boldly forth, she fell to the ground. Though much bruised, her senses did not leave her; she uttered no cry; nay, she hailed the accident that had led her to something like a screen; and creeping close up to the angle formed by the buttress, so that on one side at least she was sheltered from view, she gathered her slight and small form into its smallest compass, and breathlessly awaited her fate.
