Cinta frowned. She couldn’t have heard that right, or else she had misinterpreted. Welton couldn’t seriously be considering a snatch job. “Say again?” she asked.

“I said we might want Lentrall for ourselves. More accurately, we might want to keep him, and his work, from the Infernals, if only for a little while.”

“Madame Welton, that would be madness! Absolute madness! If he’s as important as you say-”

“He might well be that important,” Welton replied. “Important in the way a plague or your local star going nova might be considered important. He’s a disaster waiting to happen. And if there is any madness about, he’s the one who has it. You will establish a full, round-the-clock watch on Lentrall-and you will prepare a contingency plan to kidnap him and hold him. Plan on the assumption of an attempt within the next few days, and hold the operation in hot-standby. I want a plan we can adapt to as many circumstances as possible, and one we can carry out within one hour of my giving the command.” There was a pause on the line, and for a moment, Cinta thought Tonya Welton was finished speaking. But then she spoke again. “And while you’re at it,” said Tonya Welton, “you might consider praying we’re not too late already.”

“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 dates on Gervad’s ID database against Sapper 323’s, he discovered that Gervad’s was only a few days old, while Sapper 323’s list had not been updated in a year and a half. That was not surprising, given the fact that the Sappers were not the most popular model in the world. The rental shop where Justen had gotten it had had a dozen Sappers powered down in the back.

Gervad’s database had Ardosa, but his database also showed that Ardosa’s records had been entered five years before-although Sapper 323’s eighteen-month-old database had no record of him at all.

In short, it was painfully clear that someone had managed to manipulate the police data files, and gone to that effort at least in part to insert an operative into the University of Hades faculty. It seemed unlikely that they had gone to all that trouble just for this one man. They were going to have cross-check the entire identity list-and start the long, dreary search for the security breach as well. Tiresome stuff. Justen gave silent thanks that he was not an officer in counterintelligence. They were going to have a mind-numbing job ahead of them.

But where had they-whoever “they” were-decided to put their man? Justen checked the listing a bit more carefully. In what part of the university did Ardosa spend his days?

When he got his answer, the hairs on the back of his head seemed to stand on end. The University’s Center for Terraforming Studies. That explained a great deal-a bit too much for Justen’s comfort. He had been quite mystified by the notion of someone bothering to insert an agent to watch over the moribund confines of the university. But terraforming was quite another matter.

The struggle to reconstruct the planet’s climate was at the core of all the other issues of the day. Whoever controlled the reterraforming project controlled power, and not just the raw, physical power of the terraforming machinery, but every other sort of power as well: financial, political, intellectual, everything. It made all the sense in the world for the Settlers or the Ironheads or anyone else to insert a man into the Terraforming Studies Center.

But something didn’t fit. Ardosa-whoever he really was-was not at all the sort of person Devray had been looking for outside the entrance to Settlertown. That stakeout was an ongoing operation, an attempt to establish a pattern of routine comings and goings. Casuals and walk-ins, as they were known in the trade. A deep-cover agent would know better than to use the front entrance, and thus risk blowing his cover. Unless there was something so urgent and important that it was worth risking all.

But terraforming was a project for the generations. It moved, of necessity, at a leisurely pace. Any given project was likely to take years to accomplish. What sort of terraforming information could be as urgent as Ardosa’s behavior suggested it had to be? Why go in the front door? Why not send word some other way? It was plainly impossible to shut down all forms of communication. There was always some way to pass a message in reasonable safety, provided you were willing to take a little time. You could send a written message carried by a robot. You could use a dead-drop, something as simple as a scribbled message hidden under a rock. You could send a perfectly normal hyperwave message saying something like, “Your shoes are ready to be collected,” or “Please order porridge for my breakfast,” with each phrase having a prearranged meaning.

Ardosa had to have some such way to contact the Settlers.

So what could be so vitally important that he would throw all that over and dive for the front door?
