He bent to help the man to his feet, but the other would have none of that. He evaded the friendly hand and screeched in a high-pitched voice.

"Officer, officer, police ... HELP! I've been attacked—a mad robot ... HELP!"

A crowd was gathering—staying at a respectful distance—but making an angry muttering noise. Jon stood motionless, his head reeling at the enormity of what he had done. A policeman pushed his way through the crowd.

"Seize him, officer, shoot him down ... he struck me ... almost killed me ..." The man shook with rage, his words thickening to a senseless babble.

The policeman had his .75 recoilless revolver out and pressed against Jon's side.

"This man has charged you with a serious crime, grease-can. I'm taking you into the station house—to talk about it." He looked around nervously, waving his gun to open a path through the tightly packed crowd. They moved back grudgingly, with murmurs of disapproval.

Jon's thoughts swirled in tight circles. How did a catastrophe like this happen, where was it going to end? He didn't dare tell the truth, that would mean he was calling the man a liar. There had been six robots power-lined in the city since the first of the year. If he dared speak in his own defense there would be a jumper to the street lighting circuit and a seventh burnt out hulk in the police morgue.

A feeling of resignation swept through him, there was no way out. If the man pressed charges it would mean a term of penal servitude, though it looked now as if he would never live to reach the court. The papers had been whipping up a lot of anti-robe feeling, you could feel it behind the angry voices, see it in the narrowed eyes and clenched fists. The crowd was slowly changing into a mob, a mindless mob as yet, but capable of turning on him at any moment.

"What's goin' on here...?" It was a booming voice, with a quality that dragged at the attention of the crowd.

A giant cross-continent freighter was parked at the curb. The driver swung down from the cab and pushed his way through the people. The policeman shifted his gun as the man strode up to him.
