Fascinated, he watched the moonbeam and all at once the terror faded. He dropped the bear and crawled on hands and knees, stalking the moonbeam. It did not try to get away and he reached its edge and thrust his hands into it and laughed with glee when his hands were painted by the light coming through the window. He lifted his face and stared up at the blackness and saw the white globe of the Moon, looking at him, watching him. The Moon seemed to wink at him and he chortled joyfully. Behind him a door creaked open and he turned clumsily around. Someone stood in the doorway, almost filling it—a beautiful person who smiled at him. Even in the darkness he could sense the sweetness of the smile, the glory of her golden hair. "Time to eat, Andy," said the woman. "Eat and get a bath and then to bed." Andrew Young hopped joyfully on both feet, arms held out—happy and excited and contented. "Mummy!" he cried. "Mummy ... Moon!" He swung about with a pointing finger and the woman came swiftly across the floor, knelt and put her arms around him, held him close against her. His cheek against hers, he stared up at the Moon and it was a wondrous thing, a bright and golden thing, a wonder that was shining new and fresh. On the street outside, Stanford and Riggs stood looking up at the huge house that towered above the trees. "She's in there now," said Stanford. "Everything's quiet so it must be all right." Riggs said, "He was crying in the garden. He ran in terror for the house. He stopped crying about the time she must have come in." Stanford nodded. "I was afraid we were putting it off too long, but I don't see now how we could have done it sooner. Any outside interference would have shattered the thing he tried to do. He had to really need her. Well, it's all right now. The timing was just about perfect." "You're sure, Stanford?" "Sure? Certainly I am sure. We created the android and we trained her. We instilled a deep maternal sense into her personality. She knows what to do. She is almost human. She is as close as we could come to a human mother eighteen feet tall. We don't know what Young's mother looked like, but chances are he doesn't either.
