It was with a painful feeling of suspense and agitation that she set forth upon this attempt at flight, which she knew must be a final one. Over her left arm she threw the rope-ladder, while in her left hand she held that ancestral dagger which had already done her such good service in her dealings with Leon. Her right hand was thus free to grope in the dark for her way, to open bolts, or to seize the dagger from her other hand whenever the need for it might arise. For this last dread necessity she had thoroughly prepared herself. By the desperation of her position, and by the dark menaces of Leon, she had been nerved to a courage beyond even that elevated standard which her high spirit ordinarily reached, and she had resolved that if any one interposed between herself and that liberty for which she longed, to use that dagger, and to strike without scruple. On leaving her room she stood for a moment in the outer hall and listened. All was still. She glided noiselessly along, and reached the stairway. Once more she stood and listened before descending. There was silence yet. She now descended the stairs as noiselessly as before, and reached the lower hall, where she walked quickly toward the east end, and came to the narrow stairway that led down to the door. Here once more she paused. A fearful thought came to her as she looked down. What if some one should be waiting there in the dark! What if Leon should be there! In spite of herself a shudder passed through her at that thought. Suddenly, as she stood there, she heard a sound--a sound which roused her once more to action, and inspired new fears. It was the sound of a footfall--far away, indeed, inside the house, but still a footfall--a heavy tread, as of some one in pursuit, and its sound was loud and menacing to her excited senses. There was only one to whom she could attribute it--Leon! He had heard her, then! She was pursued! Like lightning this thought came to her, and brought terror with it. She could delay no longer. Down the narrow stairway she hurried through the darkness, and reached the door. In her panic she forgot her usual caution. With a jerk she drew the bolt back, and a harsh grating sound arose. She flung open the door, which also creaked on its unused hinges. Then leaping out, she hastily banged the door after her, and ran straight on.
