“Run it again, Gervad,” said Justen Devray. “With full enhancement and magnification.”

“Yes, sir.” Gervad activated the controls, and ran his own downloaded memory sequence one more time.

Devray watched as the imagery bloomed to life one more time. The bald head of Barnsell Ardosa appeared on the screen, the image rendered grainy and jerky by the magnification routine. Justen had run this imagery, and the images from Sapper 323, a dozen times by now. The Sapper’s imagery was a trifle sharper, but Gervad had had a very slightly better angle. Once he had downloaded a copy of the Sapper’s pertinent surveillance imagery, Devray had left the Sapper on the scene, with the surveillance aircar, and orders to watch for Ardosa’s reappearance. Sapper 323 was to follow him wherever he went, as discreetly as possible.

“All right, Gervad. Freeze on the clearest frame, and show me the image you got a match pattern from next to it,” Justen said, his voice eager, his expression alert. There was, in every good law officer, at least a bit of the hunter, of the pursuer, of the tracker who would follow the trail and never give up. That part of Justen had been very much awakened by the appearance of Barnsell Ardosa. Or at least by the someone who called himself that at the moment.

The robot obeyed Justen’s order, and the two still images – one grainy and slightly distorted, the other a sharp, clear identity scan – appeared on the flat screen.

There were times that robot identity matches failed altogether, when a robot declared an identity match between two images that a human would reject instantly as being of two different people. But not this time. The surveillance image might be of extremely low quality, but it was unquestionably the same man as in the university’s identity-scan image.

Justen stared hard at the surveillance image. The enhancement system had cleaned it up at least somewhat, but there were limits to how much one could use that sort of thing. Justen knew he could have ordered the robot to clean it up even more, but they were already at the point where the enhancements were close to guesswork. They would start losing information instead of gaining it if they did any more to the pictures. A more enhanced version might look better, but it would also look less like Ardosa.

Less like Ardosa. That thought resonated with Justen for some reason; but he was not sure why. Not yet. Let it ride. Let it come to him.

Justen Devray allowed himself a small smile. There were few things easier than not looking like Barnsell Ardosa. After all, it was becoming increasingly obvious that Ardosa did not exist. Justen had gotten his first clue to that interesting little fact when he starting trying to find out why Sapper 323’s pattern-match lists did not show Ardosa. The Sapper’s database should have included everything that Gervad’s had.

The explanation had turned out to be remarkably simple. Alarming, but simple. When Justen compared the
