The robot walked down the steps. People attracted by the police car made a wide aisle for him to the street. They watched him as he walked out of sight. * * * * * That night there was a mass meeting in the university's Memorial Gymnasium, attended by several hundred men. They walked in and silently took their seats, some on the playing floor, others in the balcony over the speaker's platform. There was very little talking; the air was tense. On the platform at the end of the gym were Mayor Harry Winters, Chief of Police Sam Higgins, and Prof. Ansel Tomlin. "Men," the mayor began, "there is loose in our city a being from another world whom I'm afraid we took too lightly a few days ago. I am speaking of the humanoid--George of Zanthar. It is obvious the machine means business. He evidently came in with one purpose--to prepare Earth for others just like him to follow. He is testing us. He has, as you know, killed two men. Richard Knight, who may have erred in attacking the machine, is nonetheless dead as a result--killed by a force we do not understand. A few minutes later Sergeant Gerald Phillips of the police force was killed in the performance of his duty, trying to arrest the humanoid George for the death of Mr. Knight. We are here to discuss what we can do about George." He then introduced Prof. Tomlin who told all he knew about the blue man, his habits, his brain, the experiences with him for the past two and a half weeks. "If we could determine the source of his power, it might be possible to cut it off or to curtail it. He might be rendered at least temporarily helpless and, while in such a condition, possibly be done away with. He has told me he is vulnerable to force, such as a speeding bullet, if it hit the right spot, but George possesses the ability to read intent long before the commission of an act. The person need not even be in the room. He is probably listening to me here now, although he may be far away." The men looked at one another, shifted uneasily on their seats, and a few cast apprehensive eyes at the windows and doorways. "Though he is admittedly a superior creature possessed of powers beyond our comprehension, there must be a weak spot in his armor somewhere. I have dedicated myself to finding that weakness." The chair recognized a man in the fifth row. "Mr. Mayor, why don't we all track him down and a lot of us attack him at once? Some of us would die, sure, but he couldn't strike us _all_ dead at one time. Somebody's bound to succeed." "Why not try a high-powered rifle from a long way off?" someone else suggested, frantically. "Let's bomb him," still another offered. The mayor waved them quiet and turned to Prof. Tomlin. The professor got to his feet again. "I'm not sure that would work, gentlemen," he said. "The humanoid is able to keep track of hundreds of things at the same time. No doubt he could unleash his power in several directions almost at once."
