"Intelligence agent sounds better."

Thorby shrugged. "If he was spying, he'd call it that. Pop never minced words."

"No, he never minced words," Brisby agreed, wincing as he recalled being scorched right through his uniform by a dressing-down. "Let me explain. Mmm... know any Terran history?"

"Uh, not much."

"It's a miniature history of the race. Long before space travel, when we hadn't even filled up Terra, there used to be dirtside frontiers. Every time new territory was found, you always got three phenomena: traders ranging out ahead and taking their chances, outlaws preying on the honest men -- and a traffic in slaves. It happens the same way today, when we're pushing through space instead of across oceans and prairies. Frontier traders are adventurers taking great risks for great profits. Outlaws, whether hill bands or sea pirates or the raiders in space, crop up in any area not under police protection. Both are temporary. But slavery is another matter -- the most vicious habit humans fall into and the hardest to break. It starts up in every new land and it's terribly hard to root out After a culture falls ill of it, it gets rooted in the economic system and laws, in men's habits and attitudes. You abolish it; you drive it underground -- there it lurks, ready to spring up again, in the minds of people who think it is their 'natural' right to own other people. You can't reason with them; you can kill them but you can't change their minds."

Brisby sighed. "Baslim, the Guard is just the policeman and the mailman; we haven't had a major war in two centuries. What we do work at is the impossible job of maintaining order on the frontier, a globe three thousand light-years in circumference -- no one can understand how big that is; the mind can't swallow it.

"Nor can human beings police it. It gets bigger every year. Dirtside police eventually close the gaps. But with us, the longer we try the more there is. So to most of us it's a job, an honest job, but one that can never be finished.

"But to Colonel Richard Baslim it was a passion. Especially he hated the slave trade, the thought of it could make him sick at his stomach -- I've seen. He lost his leg and an eye -- I suppose you know -- while rescuing a shipload of people from a slaving compound.

"That would satisfy most officers -- go home and retire. Not old Spit-and-Polish! He taught a few years, then he went to the one corps that might take him, chewed up as he was, and presented a plan.

"The Nine Worlds are the backbone of the slave trade. The Sargony was colonized a long time ago, and they never accepted Hegemony after they broke off as colonies. The Nine Worlds don't qualify on human rights and don't want to qualify. So we can't travel there and they can't visit our worlds.

"Colonel Baslim decided that the traffic could be rendered uneconomic if we knew how it worked in the Sargony. He reasoned that slavers had to have ships, had to have bases, had to have markets, that it was not just a vice but a business. So he decided to go there and study it.

"This was preposterous -- one man against a nine-planet empire... but the Exotic Corps deals in preposterous notions. Even they would probably not have made him an agent if he had not had a scheme to get his reports out. An agent couldn't travel back and forth, nor could he use the mails -- there aren't any between us and them -- and he certainly couldn't set up an n-space communicator; that would be as conspicuous as a brass band.

"But Baslim had an idea. The only people who visit both the Nine Worlds and our own are Free Traders. But they avoid politics like poison, as you know better than I, and they go to great lengths not to offend local customs. However Colonel Baslim had a personal 'in' to them.

"I suppose you know that those people he rescued were Free Traders. He told 'X' Corps that he could report back through his friends. So they let him try. It's my guess that no one knew that he intended to pose as a beggar -- I doubt if he planned it; he was always great at improvising. But he got in and for years he observed and got his reports out.

"That's the background and now I want to squeeze every possible fact out of you. You can tell us about methods -- the report I forwarded never said a word about methods. Another agent might be able to use his methods."

Thorby said soberly, "Ill tell you anything I can. I don't know much."

"You know more than you think you do. Would you let the psych officer put you under again and see if we can work total recall?"

"Anything is okay if it'll help Pop's work."

"It should. Another thing --" Brisby crossed his cabin, held up a sheet on which was the silhouette of a spaceship. "What ship is this?"

Thorby's eyes widened. "A Sargonese cruiser."

Brisby snatched up another one. "This?"

"Uh, it looks like a slaver that called at Jubbulpore twice a year."

"Neither one," Brisby said savagely, "is anything of the sort. These are recognition patterns out of my files -- of ships built by our biggest shipbuilder. If you saw them in Jubbulpore, they were either copies, or bought from us!"

Thorby considered it. "They build ships there."

"So I've been told. But Colonel Baslim reported ships' serial numbers -- how he got them I couldn't guess; maybe you can. He claims that the slave trade is getting help from our own worlds!" Brisby looked unbearably disgusted.

Thorby reported regularly to the Cabin, sometimes to see Brisby, sometimes to be interviewed under hypnosis by Dr. Krishnamurti. Brisby always mentioned the search for Thorby's identity and told him not to be discouraged; such a search took a long time. Repeated mention changed Thorby's attitude about it from something impossible to something which was going to be true soon; he began thinking about his family, wondering who he was? -- it was going to be nice to know, to be like other people.

Brisby was reassuring himself; he had been notified to keep Thorby off sensitive work the very day the ship jumped from Hekate when he had hoped that Thorby would be identified at once. He kept the news to himself, holding fast to his conviction that Colonel Baslim was never wrong and that the matter would be cleared up.

When Thorby was shifted to Combat Control, Brisby worried when the order passed across his desk -- that was a "security" area, never open to visitors -- then he told himself that a man with no special training couldn't learn anything there that could really affect security and that he was already using the lad in much more sensitive work. Brisby felt that he was learning things of importance -- that the Old Man, for example, had used the cover personality of a one-legged beggar to hide two-legged activities... but had actually been a beggar; he and the boy had lived only on alms. Brisby admired such artistic perfection -- it should be an example to other agents.

But the Old Man always had been a shining example.

So Brisby left Thorby in combat control. He omitted to make permanent Thorby's acting promotion in order that the record of change in rating need not be forwarded to BuPersonnel. But he became anxious to receive the dispatch that would tell him who Thorby was.

His executive was with him when it came in. It was in code, but Brisby recognized Thorby's serial number; he had written it many times in reports to "X" Corps. "Look at this, Stinky! This tells us who our foundling is. Grab the machine; the safe is open."

Ten minutes later they had processed it; it read:

-- "NULL BESULT FULL IDENTSEARCH BASLIM THORBY GDSMN THIRD. AUTH & DRT TRANSFER ANY RECEIVING STATION RETRANSFER HEKATE INVESTIGATION DISPOSITION -- CHFBUPEBS."

"Stinky, ain't that a mess?"

Stancke shrugged. "It's how the dice roll, boss."

"I feel as if I had let the Old Man down. He was sure the kid was a citizen."
