She found the house door still open, ran through the hall, and, without even looking into the nursery, bounded straight up the stair, and the next, and the next; then turning to the right, ran through the long avenue of silent rooms, and found her way at once to the door at the foot of the tower stair. When first the nurse missed her, she fancied she was playing her a trick, and for some time took no trouble about her; but at last, getting frightened, she had begun to search; and when the princess entered, the whole household was hither and thither over the house, hunting for her. A few seconds after she reached the stair of the tower they had even begun to search the neglected rooms, in which they would never have thought of looking had they not already searched every other place they could think of in vain. But by this time she was knocking at the old lady's door. CHAPTER 15 Woven and Then Spun 'Come in, Irene,' said the silvery voice of her grandmother. The princess opened the door and peeped in. But the room was quite dark and there was no sound of the spinning-wheel. She grew frightened once more, thinking that, although the room was there, the old lady might be a dream after all. Every little girl knows how dreadful it is to find a room empty where she thought somebody was; but Irene had to fancy for a moment that the person she came to find was nowhere at all. She remembered, however, that at night she spun only in the moonlight, and concluded that must be why there was no sweet, bee-like humming: the old lady might be somewhere in the darkness. Before she had time to think another thought, she heard her voice again, saying as before: 'Come in, Irene.' From the sound, she understood at once that she was not in the room beside her. Perhaps she was in her bedroom. She turned across the passage, feeling her way to the other door. When her hand fell on the lock, again the old lady spoke: 'Shut the other door behind you, Irene. I always close the door of my workroom when I go to my chamber.' Irene wondered to hear her voice so plainly through the door: having shut the other, she opened it and went in. Oh, what a lovely haven to reach from the darkness and fear through which she had come! The soft light made her feel as if she were going into the heart of the milkiest pearl; while the blue walls and their silver stars for a moment perplexed her with the fancy that they were in reality the sky which she had left outside a minute ago covered with rainclouds. 'I've lighted a fire for you, Irene: you're cold and wet,' said her grandmother.
