But he was talking to a retreating group of men. Newsmen walked quickly to what they thought was a safe distance. The radio men silently packed their gear. The TV cameras were rolled noiselessly away.

Prof. Tomlin, alone on the porch with the robot, turned to him and said, "Much of what you have told me comes to have new meaning, George. I understand what you mean when you talk about people being willing to work for your so-called Seventh Order."

"I knew you were a better than average man, Professor Tomlin," the humanoid said, nodding with gratification.

"This is where I get off, George. I'm warning you now that you'd better return to your ship or whatever it is you came in. People just won't stand for what you've done. They don't like murder!"

"I cannot return to my ship," George said. "I destroyed it when I arrived. Of course I could instruct some of you how to build another for me, but I don't intend to leave, anyway."

"You will be killed then."

"Come, now, Professor Tomlin. You know better than that."

"If someone else can't, then perhaps I can."

"Fine!" The robot replied jovially. "That's just what I want you to do. Oppose me. Give me a real test of your ability. If you find it impossible to kill me—and I'm sure you will—then I doubt if anyone else will be able to."

Prof. Tomlin lit a cigaret and puffed hard at it. "The trouble with you," he said, eying the humanoid evenly, "is that your makers forgot to give you a conscience."
