All that had just occurred seemed like a strange dream to Isabelle, now that she found herself alone again.  She remained for some time at the open casement, looking at the great tree opposite, and trembling as she realized the terrible risk Chiquita had run for her sake—­feeling warm gratitude and tender affection for the wild, incomprehensible little creature, who manifested such a strong attachment for herself, and a new hope sprang up in her heart as she thought that now de Sigognac would soon know where to find her.  The cold night air at last forced her to close the window, and after arranging the curtains over it carefully, so as to show no signs of having been disturbed, she returned to her easy-chair by the fire; and just in time, for she had scarcely seated herself when the major-domo entered, followed by the two servants, again carrying the little table, set for one, with her supper daintily arranged upon it.  A few minutes earlier and Chiquita’s escape would have been discovered and prevented.  Isabelle, still greatly agitated by all that had passed, could not eat, and signed to the servants to remove the supper untouched.  Whereupon the major-domo himself put some bread and wine on a small table beside the bed, and placed on a chair near the fire a richly trimmed dressing-gown, and everything that a lady could require in making her toilet for the night.  Several large logs of wood were piled up on the massive andirons, the candles were renewed, and then the major-domo, approaching Isabelle with a profound obeisance, said to her that if she desired the services of a maid he would send one to her.  As she made a gesture of dissent he withdrew, after again bowing to her most respectfully.  When they had all gone, Isabelle, quite worn out, threw herself down on the outside of the bed without undressing, so as to be ready in case of any sudden alarm in the night; then took out Chiquita’s knife, opened it, and laid it beside her.  Having taken these precautions, she closed her eyes, and hoped that she could for a while forget her troubles in sleep; but she had been so much excited and agitated that her nerves were all quivering, and it was long before she even grew drowsy.  There were so many strange, incomprehensible noises in the great, empty house to disturb and startle her; and in her own room, the cracking of the furniture, the ticking of a death-watch in the wall near her bed, the gnawing of a rat behind the wainscot, the snapping of the fire.  At each fresh sound she started up in terror, with her poor heart throbbing as if it would burst out of her breast, a cold perspiration breaking out on her forehead, and trembling in every limb.  At last, however, weary nature had to succumb, and she fell into a deep sleep, which lasted until she was awakened by the sun shining on her face.  Her first thought was to wonder that she had not yet seen the Duke of Vallombreuse; but she was thankful for his absence, and hoped that it would continue until Chiquita should have brought de Sigognac to the rescue.
