"Mouse, I've run into a philosophical problem," he said one morning. "About the fish."

"You've lost me already, Moyshe."

"I've gotten onto something that's turning my thinking inside out."

"Which is?"

"That this isn't your usual man/cattle relationship. It's a partnership—if the Fishers aren't the cows. The fish are intelligent. Probably more intelligent than we are." He looked around. No one was listening. "They have what they call a mindtech section in Ops Sector. Somehow, they communicate with the starfish. Mind to mind."

"Where'd you get that?"

"Around. Keeping my ears open. Adding things up."

"So the ugly old psi theory raises its head again. Out here. You know what the Old Man's scientists will say about that?"

"They'll have to loosen up those stiff necks. But what I think is interesting is the research possibilities."

"Research?"

"Historical research. The fish have been in contact with other races. And some of them are over a million years old. That's a lot of remembering, I'm thinking."

Like oceans, the hydrogen streams supported a complete ecology, including the predatory "shark," the starfish's natural enemy. There were a dozen species. Even the biggest and most dangerous was much smaller than an adult starfish. However, like man and wolves, several of the species hunted in cooperative packs. They could even pursue their prey through hyperspace.

Packs shadowed all the great herds. They struck when a fish straggled. Sometimes, when driven by hunger, they tried to cut individual fish from the herd. And occasionally, when their numbers reached a certain critical mass, a whole pack went berserk and threw itself at the herd.

The starfish were not helpless. They could burp up balls of gut fire and sling them around like granddaddy nuclear bombs. But sharks were fast and the burping was slow. A starfish under attack seldom had a chance for more than one defensive attempt. He had to count on the help of his herdmates, who might be under attack themselves. Thus inadequate, the starfish sometimes needed allies to survive.

When the earliest Seiners had located their first starfish herd the shark packs had been expanding rapidly. That first herd had been threatened with extinction.

Its fish had touched the minds of those early Seiners, had found in them a hope, and so had contacted them and had made a bargain. They would produce ambergris in quantity in exchange for human protection.

"There're times when I think they're trying to touch me," benRabi told Mouse, after rehearsing what history he had learned.

"What makes you think that?" Mouse seemed excited by the idea.

"Probably just my imagination." He was reluctant to tell Mouse that he sometimes dreamed of vast, swimming spatial panoramas, oddly alive with things never seen by human eyes. Dragons flew there, and played, with a ponderousness unmatched even in Old Earth's vanished whales. Each time he dreamed the dream, he wakened with a screaming migraine.

"So those first Fishers armed themselves," he said, resuming his history lesson. "The fish taught them to detect the sharks. The herd slowly recovered."

But the sharks, in their slow fashion, reasoned. They learned to associate casualties with the hard things shepherding their prey. In the middle thirties they had begun getting harvestships as well as herds, forcing the Seiners to defend themselves before they protected their allies.

This past year they had begun attacking the ships first, and cooperating between packs of different species.

Their numbers were still expanding. Soon, the Seiners feared, they would be numerous enough to attack and destroy whole harvestfleets.

No ships had yet been lost, but the attack on Danion had demonstrated the reality of the peril.

The Starfishers believed themselves at war, and feared it was a war they could not win. They were too few and too weakly armed.

"Packs are migrating here from deeper in the galaxy," Moyshe concluded. "I suppose because of a depleted food supply there."

"That's it?" Mouse asked.

"What'd you expect? It's hard to get anything out of Amy. She may be sleeping with me but she doesn't forget that I'm the other old enemy, the landsman. About the only other thing is that they're desperate for more and better weapons. They might have something cooking there. Any time I mention weapons, Amy changes the subject fast."

In fact, she usually left the cabin. That scared him. Something big was going on and she did not want to risk giving him a hint.

Her behavior confirmed the feeling he had had from the beginning. This was no ordinary harvest.

Danion had been under drive for weeks. Moyshe's suspicions had become stronger. Harvestships seldom went hyper. The fish did not like it.

Were the beasts following the fleet?

Nobody was talking. Even the friendliest Seiners had little to say anymore.

The year was winding down. He had learned a lot, but still nothing concrete, nothing of genuine advantage to the Bureau and Confederation. Was the mission going to end up a wild goose chase?

Playing spy-vs-spy in the bedroom with Amy had become agonizing. Yet he had to pursue his tradecraft. He had to try to learn, and he did not dare relax.

He could not forget the Sangaree woman. She was still there, and still very much involved in her own mission.

Whatever her game was, it was in its final moves. She had resumed pushing Mouse, hard, confident of her strength.

The drives had been dead a week. Danion had reached her destination. Whole new sections of the ship had been closed to landsmen. The Seiners who came and went there were more closed mouthed than ever. Some, whom Moyshe considered friends, would barely acknowledge his greetings. Whatever they were doing, they wanted no hint to get back landside.

Work schedules went to shift-and-a-half. There were no exceptions. BenRabi and Mouse just spent that much more time being bored.

"Whatever it is, it's dangerous," Mouse said. "They're all scared green."

"The shark packs are collecting. Like ten times thicker than they've ever seen."

"I watched one of the Service Ship crews come in this morning. They rotated with an alternate crew."

"Fighting?"

"Just exhausted, I think. I didn't see any stretchers. But Kindervoort's thugs ran me off before I could find out anything."

Despite Kindervoort they gleaned their bits of information. "They're in a race against time," benRabi told Mouse. "I heard one guy say they wouldn't get a chance to gamble if the sharks hit aggressive mass before they finish their experiments."

"What did he mean? Are they working on some new weapon?"

BenRabi shrugged. "I didn't ask. But I sure wouldn't mind knowing what they're risking my life for."

One evening, after a workday spent within taunting distance of the Sangaree woman, benRabi and Mouse tried to relax over a chessboard.

"You're shook up again," Mouse observed while staring at his pieces. "What's up? Trouble with Amy?"

"That's part of it. I've only seen her twice all week. She just comes in long enough to shower and change."

"So? She's not sitting on the only one in the universe. The little redhead, Penny something, from New Earth... "

"She's young enough to be my kid, Mouse. Only a couple of years older than Greta."

Mouse flung his hands up in mock exasperation. "What's that got to do with it? She's willing, isn't she?"

"Maybe. But I think I'm more a father image... "

"So indulge in a little incest."

"It doesn't matter anyway. Sex isn't the problem."

"What? It's always a problem. One way or another." Mouse chuckled. He chuckled again as he ambushed Moyshe's queen. Moyshe could not keep his mind on his game. The want had returned, mildly, along with that damned thing with the gun. "What is the problem, then?"
