you make a report?” Which to me sounded like another version of “ if you’re so damned smart why ain’t you rich? ” which we used to snarl at the brainy kids in grammar school. Ned took such things literally though, and turned towards the door. “Do you mean you wish me to make a report on this robbery?” “Yes,” the Chief said just to get rid of him, and we watched his blue shape vanish through the door. “He must be brighter than he looks,” I said. “He never stopped to ask where Greenback’s store is.” The Chief nodded and the phone rang again. His hand was still resting on it so he picked it up by reflex. He listened for a second and you would have thought someone was pumping blood out of his heel from the way his face turned white. “The holdup’s still on,” he finally gasped. “Greenback’s delivery boy is on the line—calling back to see where we are. Says he’s under a table in the back room …” I never heard the rest of it because I was out the door and into the car. There were a hundred things that could happen if Ned got there before me. Guns could go off, people hurt, lots of things. And the police would be to blame for it all—sending a tin robot to do a cop’s job. Maybe the Chief had ordered Ned there, but clearly as if the words were painted on the windshield of the car, I knew I would be dragged into it. It never gets very warm on Mars, but I was sweating. Nineport has fourteen traffic regulations and I broke all of them before I had gone a block. Fast as I was, Ned was faster. As I turned the corner I saw him open the door of Greenback’s store and walk in. I screamed brakes in behind him and arrived just in time to have a gallery seat. A shooting gallery at that. There were two holdup punks, one behind the counter making like a clerk and the other lounging off to the side. Their guns were out of sight, but blue-coated Ned busting through the door like that was too much for their keyed up nerves. Up came both guns like they were on strings and Ned stopped dead. I grabbed for my own gun and waited for pieces of busted robot to come flying through the window. Ned’s reflexes were great. Which I suppose is what you should expect of a robot. “DROP YOUR GUNS, YOU ARE UNDER ARREST.” He must have had on full power or something, his voice blasted so loud my ears hurt. The result was just what you might expect. Both torpedoes let go at once and the air was filled with flying slugs. The show windows went out with a crash and I went down on my stomach. From the amount of noise I knew they both had recoilless .50’s. You can’t stop one of those slugs. They go right through you and anything else that happens to be in the way. Except they didn’t seem to be bothering Ned. The only notice he seemed to take was to cover his eyes. A little shield with a thin slit popped down over his eye lenses. Then he moved in on the first thug. I knew he was fast, but not that fast. A couple of slugs jarred him as he came across the room, but before the punk could change his aim Ned had the gun in his hand. That was the end of that. He put on one of the sweetest hammer locks I have ever seen and neatly grabbed the gun when it dropped from the limp fingers. With the same motion that slipped the gun into a pouch he whipped out a pair of handcuffs and snapped them on the punk’s wrists. Holdupnik number two was heading for the door by then, and I was waiting to give him a warm reception. There was never any need. He hadn’t gone halfway before Ned slid in front of him. There was a thud when they hit that didn’t even shake Ned, but gave the other a glazed look. He never even knew it when Ned slipped the cuffs on him and dropped him down next to his partner. I went in, took their guns from Ned, and made the arrest official. That was all Greenback saw when he crawled out from behind the counter and it was all I wanted him to see. The place was a foot deep in broken glass and smelled
