"Yeah. Plenty. Our androids are busy, all right. They're out in the city, every one of them. We've had a dozen police reports already."

"Police reports! What's wrong?"

Jack shook his head. "It's crazy. They're swarming all over Carron City. They're stopping robots in the streets—household Robs, commercial Droids, all of them. They just look at them, and then the others quit work and start off with them. The police sent for us to come and get ours."

"Why don't the police do something about it?"

"Hah!" barked a voice behind us. I swung around, to face Chief of Police Dalton of Carron City. He came straight toward me, his purplish jowls quivering with rage, and his finger jabbed the air in front of my face.

"You built them, Don Morrison," he said. "You stop them. I can't. Have you ever tried to shoot a robot? Or use tear gas on one? What can I do? I can't blow up the whole town!"

Somewhere in my stomach I felt a cold, hard knot. Take stainless steel alloyed with titanium and plate it with three inches of lead. Take a brain made up of super-charged magnetic crystals enclosed in a leaden cranium and shielded by alloy steel. A bullet wouldn't pierce it; radiations wouldn't derange it; an axe wouldn't break it.

"Let's go to town," I said.

They looked at me admiringly. With three hundred almost indestructible androids on the loose I was the big brave hero. I grinned at them and hoped they couldn't see the sweat on my face. Then I walked over to the Copter and climbed in.

"Coming?" I asked.
