And who was Ardosa? Devray was certain he had seen that face before. But where? He studied both images again. It was a distinctive face, not the sort that would get lost in the shuffle. In the surveillance imagery, it was wearing a worried look, and the identity scan image had that awkward, glazed, expressionless look of so many identity photos, the subject caught by the camera the moment before deciding what to do with his or her face.

As Justen stared at the images, there was one thing he became more and more sure about. He had never seen whoever it was in the flesh. He had simply seen an image of this man before. A flat-photo, a hologram, something like that.

A case file, then. That was what it had to be. The mug shots from some case he had worked on, or studied. A case big enough that Devray had studied every mug shot hard enough and long enough to have them burned into his skull. But Ardosa had not been a central figure in whatever case it was. Otherwise, Devray would have known him instantly.

A thought that had flitted through his mind a few moments before came back to him. Less like Ardosa. Was that part of his subconscious whispering that Ardosa no longer looked quite the way he had, whenever Devray had seen him? And it would have to be an older case, or else, Justen knew, he would remember the face clearly. He studied the images one more time. “Gervad,” he said, “delete the mustache from both images. And give me a range of reverse age regressions. Not in Spacer mode. We age too slowly. Do it in Settler mode. Go back ten chronological years or so. Standard spread.”

“Yes, sir.” The robot operated the image control system with a smooth skill, and the two images shrank to take up only a small fraction of the screen before the mustaches faded away from each of them, leaving a vague patch of simulation, the computer’s best estimate of what sort of upper lip existed under the man’s facial hair.

Then the faces multiplied, and began to shift and change, transmogrifying into younger variants. Some versions of the face grew thinner, or sprouted new hair. Wrinkles vanished, the slight double chin melted away. But there were so many ways for a man to age, and so many ways a man could prevent the aging, in whole or in part, if he chose to do so. Spacers, of course, made every effort to stop the aging process completely-but Settlers did not. They let themselves grow old.

Spacers were not used to people aging, not used to seeing their appearance change over time. If a near-ageless Spacer became friends with a youthful Settler, lost track of him, and then encountered the same Settler twenty years later, the Spacer would have a great deal of difficulty recognizing the older version of the Settler as being the same person. But Spacers had not lost this skill altogether. It could still be brought into play with a little encouragement.

The computer graphics system manipulated the images at a rapid clip. Within seconds, Devray was faced with two dozen versions of the same face, shifted and changed and re-formed. He studied each of them in turn. He was tempted to reject most of them at once, but resisted the urge to move too fast. He trusted his instincts, but only so far. Suppose the face he rejected turned out to be the one that spurred his memory? But still and all, he had to trust what his subconscious was telling him. Number One had too much hair. Number Two looked far too young. Three and Four were plainly too thin, while Six and Eight were far too portly.

Justen Devray stared at the images, slowly, carefully, one at a time. Something in the back of his head whispered that he was close, that he was going to get the answer, that he was about to make the connection.

And then he saw it. Face Number Fifteen. That was the one he knew. He was sure of it. And suddenly, in a moment like a piece dropping itself into place in the puzzle, he knew. He knew who it was.

He had seen Ardosa’s mug shot before, all right. And the man calling himself Ardosa had been involved, if on the periphery, of a big case. The biggest case Justen Devray had ever been on. The murder, five years before, of Governor Chanto Grieg.

JUSTEN RUBBED HIS face and blinked hard. “I’m sorry I’m a bit punchy, sir. I’ve been up all night on this one. I came straight from the archives room to here. “ He blinked and stretched, trying to bring the room into focus. Apparently Kresh’s wife was waiting in the main office, just down the hall, and that was why Kresh had brought him in here, to an assistant’s office, for the meeting. Kresh had assured him the assistant would not be in for another hour, but even so…The paintings on the wall, the tastefully chosen furniture and decoration, made it seem a strangely personal space. Justen felt as if he were intruding.

“It’s all right, son,” Kresh said. “Sit down.” Kresh sat on one end of a low couch, and gestured for Devray to sit down on the other end. Justen did so, gratefully. “Donald, bring the Commander something hot and strong with a dose of caffeine in it.”

“At once, Governor,” Donald replied, and went off to take care of it.

“All right then, Commander. My wife and I have a rather important meeting at ten this morning. That gives us just about an hour. Will that be enough for whatever it is?”

“I don’t think it’ll take five minutes, sir.” Justen hesitated a moment, and then decided to plunge ahead. “This appointment at ten, sir-would it by any chance be with a Davlo Lentrall?”

Kresh looked surprised. “It would indeed, Commander. I haven’t told anyone I’m meeting with him again, outside of my wife. Might I ask where you got that particular tidbit of information?”

“Thank you, Donald,” said Justen. Kresh’s personal robot had returned with a cup of what seemed to be remarkably strong tea, and Justen took it from him. Like most Spacers, Justen rarely bothered handing out “pleases” and “thank yous” to robots, but, somehow, Donald 111 was a special case. He took a quick sip of the tea, and found it as reviving as he had hoped. “I got my information from two sources,” he went on. “From our old and dear friends in the Settler Security Service, and from the Ironheads. Neither of them gave me the information on purpose, of course, and neither of them knows what I’ve found out. But I learned it from them, all the same. If they don’t know all about him by now, they will, very soon. And whatever he’s involved in has got both outfits about to go ballistic.”

“Do you know what Lentrall’s been working on?” Kresh asked.

“No, sir. But if the Settlers and the Ironheads don’t know by now, they will by lunchtime. I can tell you they are both digging as hard as they can.”

“Why don’t you start at the beginning, son?” Kresh suggested.

“Yes, sir. I’ve been sitting in on the various ongoing operations, just to see how things are going, to get a feel for what my officers have to deal with, and so on.”

“And it gets you out of the office now and then,” Kresh said with a smile. “I used to do the same thing when I was running the Sheriff’s Department.”

Justen smiled back. It helped a great deal to have a governor who used to run a law enforcement agency. He understood things without needing too much explanation. “Yes, sir. In any event, I sat in on the Settlertown main entrance stakeout. Normally the officer assigned to that duty is expected to provide his or her own vehicle or other watch post, and his or her own robotic assistance, and is later reimbursed. The thinking is that keeps us from using the same three vehicles and the same three robots over and over. It should make us harder to spot. It also encourages the officers to be a bit more creative, show some initiative. In any event, I did the drill myself. I brought my own personal robot, and rented a second robot and an aircar. That stakeout is sort of a grab-bag affair, more than anything. Every once in a while we spot someone going in who shouldn’t be, and we can run some checks.”
