He stood with folded arms. The light was dim, but such as it was it shone full upon him. His face was, as always, a mask of imperturbability. "Mistress Mary knows that I love her." He said it with a startlingly calm abruptness. Mary shuddered against me, but she did not speak. I thought possibly Tugh was not armed; I could leap upon him. Doubtless I was stronger than he. But outside the door Migul was armed with a white-ray. "I love her as I have always loved her.... But this is no time to talk of love. I have much on my mind; much to do." He seemed willing to talk now, but he was talking more for Mary than for me. As I watched him and listened, I was struck with a queerness in his manner and in his words. Was he irrational, this exile of Time who had impressed his sinister personality upon so many different eras? I suddenly thought so. Demented, or obsessed with some strange purpose? His acts as well as his words, were strange. He had devastated the New York of 1935 because its officials had mistreated him. He had done many strange, sinister, murderous things. He said, with his gaze upon Mary, "I am going to conquer this city here. There will follow the rule of the Robots--and I will be their sole master. Do you want me to tell you a secret? It is I who have actuated these mechanisms to revolt." His eyes held a cunning gleam. Surely this was a madman leering before me. "When the revolt is over," he went on, "I will be master of New York. And that mastery will spread. The Robots elsewhere will revolt to join my rule, and there will come a new era. I may be master of the world; who knows? The humans who have made the Robots slaves for them will become slaves themselves. Workers! It is the Robots' turn now. And I--Tugh--will be the only human in power!" * * * * * These were the words of a madman! I could imagine that he might stir these mechanical beings to a temporarily successful revolt: he might control New York City; but the great human nations of the world could not be overcome so easily. And then I remembered the white-ray. A giant projector of that ray would melt human armies as though they were wax; yet the metal Robots could stand its blast unharmed. Perhaps he was no madman.... He was saying, "I will be the only human ruler. Tugh will be the greatest man on Earth! And I do it for you, Mistress Mary--because I love you. Do not shudder." He put out his hand to touch her, and when she shrank away I saw the muscles of his face twitch in a fashion very odd. It was a queer, wholly repulsive grimace. "So? You do not like my looks? I tried to correct that, Mary. I have searched through many eras, for surgeons with skill to make me like other men. Like this young man here, for instance--you. George Rankin, I am glad to have you; do not fear I will harm you. Shall I tell you why?" "Yes," I stammered. In truth I was swept now with a shuddering revulsion for this leering cripple.
