Edith set to work, and, first of all, she removed the bed-cord. It was as strong as was desirable, and far longer than was necessary. She doubled part of this, and tied knots at intervals of about a foot, and in this simple way formed what was a very good step-ladder about three yards long, which was sufficient for her purpose. Then she removed the iron curtain rod, and bent this in such a way that it formed a hook or grapple strong enough for her wants. She thus had a rope-ladder, with a grappling-iron attached, of rude construction, it is true, yet perfectly well suited to the task before her, and so light as to be quite portable. These preparations did not take up much time. After taking what she wanted of the bed-cord, there was enough left to replace in the bedstead so as to hold up the bed. She did not know what might happen, and wished to preserve appearances in the event of Mrs. Dunbar's entrance, or in case of her being compelled to postpone her project. From the same motive she also replaced the curtain so as to look as it did before, securing it in its place by means of pins. At length all these preparations were completed, and it only remained for Edith to wait for the proper time to start. The hours passed on. Midnight came, but even at that hour Edith thought that it was too early. Leon probably kept late hours, and might be wandering about. She determined to wait longer. The moon was still shining. There were only a few scattered clouds in that clear sky. Could she find her way to the wall? She felt confident of that. She intended to go down the avenue, keeping close to the trees, so as to fly to their shelter in case of pursuit. When she reached the neighborhood of the porter's lodge, she would go through the trees to the wall, trusting to fortune to find her way for that short distance. Such were the hopes and plans, made long before, which now occupied her thoughts as she waited. At last two o'clock came. It seemed now that it would be unwise to wait any longer, since the time that was left between this and daylight was barely sufficient to allow for contingencies. Without any farther delay, therefore, she prepared to depart.
