Gradually, once more, the sunlight faded, and the darkness began to creep over the land. Never before had the shadows under the elms looked so fantastic, nor the bushes in the field beyond assumed such sinister shapes. The Empty House was being gradually invested; the enemy was masquerading already under cover of these very shadows. Very soon, he felt, the attack would begin, and he must be ready to act. The night came down at last with a strange suddenness, and with it the warning of the governess came back to him; he thought quakingly of the stricken children who had been caught and deprived of their wings; and then he pulled out his long red feathers and tried their strength, and gained thus fresh confidence in their power to save him when the time came. CHAPTER XVII OFF! With the full darkness a whole army of horrors crept nearer. He felt sure of this, though he could actually see nothing. The house was surrounded, the courtyard crowded. Outside, on the stairs, in the other rooms, even on the roof itself, waited dreadful things ready to catch him, to tear off his wings, to make him prisoner for ever and ever. The possibility that something had happened to the governess now became a probability. Imperceptibly the change was wrought; he could not say how or when exactly; but he now felt almost certain that the effort to keep her out of the way had succeeded. If this were true, the boy's only hope lay in his wings, and he pulled them out to their full length and kissed them passionately, speaking to the strong red feathers as if they were living little persons. "You must save me! You will save me, won't you?" he cried in his anguish. And every time he did this and looked at them he gained fresh hope and courage. The problem _where he was to fly to_ had not yet insisted on a solution, though it lay always at the back of his mind; for the final flight of escape without a guide had never been even a possibility before. Lying there alone in the darkness, waiting for the sound of the voice so longed-for, he found his thoughts turning again to the moon, and the strange words of the song that had puzzled him the night before. What in the world did it all mean? Why all this about the moon? Why was it a cruel moon, and why should it attract and persuade and entice him? He felt sure, the more he thought of it, that this had all been a device to draw him to the window--and perhaps even farther. The darkness began to terrify him; he dreaded more and more the waiting, listening things that it concealed. Oh, when would the governess call to him? When would he be able to dash through the open window and join her in the sky?
