shelter. Most drowned; some killed one another.
And out of their bodies, eventually, grew the pretty flowers of the island, in new profusion.
Scientists speculated that some sort of elemental organism—based not on carbon or silicon, but on the iron oxides in the rocks of their pretty island—interacted through the air not with them but with the synthetic food rations they brought to help them until they could develop their own native agriculture.
And they had eaten it, and it had eaten them.
But there had been one survivor—one woman who had hidden in the huge beds of alien sponge along a particularly rocky shoreline. Oh, she had died, too—but almost three weeks later than the others. When she no longer returned each evening to sleep in the sponge bed.
The natural secretions of the sponge acted as a retardant—not as an antidote. But as long as a victim had a daily intake of the secretion, the mutant strain seemed inactive. Remove the substance—and the degenerative process began once again. But scientists had taken some samples of the mutant strain and of living sponge with them to study in their labs on far-off worlds. All of it was thought to have been destroyed afterward—but evidently some had not been. Some had been taken by the worst of elements and was developed in their own labs in unknown space.
The perfect commodity.
By secretly introducing the stuff into people's food, you gave them the disease. Then, when the first symptoms came and baffled all around you, the merchant would come. He would ease the pain and cause normality by giving you a little bit of sponge—as Hain was administering a dose to Wu Julee at that very moment.
The Confederacy wouldn't help you. It maintained a sponge colony on that interdicted world for the afflicted, where one could live a normal, if very primitive, existence and soak each night in a sponge bath. If, that is, the victim could be gotten there before the disease became too progressive to bother.
The sponge merchants chose only the most wealthy and powerful—or their children, if their world had families of any sort. There was no charge for the daily sponge supply, oh, no. You just did as they asked when they asked.
There was even the suspicion that so many rulers of the Confederacy were hostage to the stuff now that that was the reason no real search for an antidote or cure had ever been started.
For power was the ultimate aim of the sponge merchants.
Nathan Brazil wondered who Wu Julee was. The daughter of some big-shot ruler or banker or industrialist? Maybe the child of the Confederacy enforcement chief? More likely she was a sample, he thought. No use risking exposure.
She was his absolute slave, no question. The disease had been allowed to incubate in her just short of that critical point when the stuff multiplied exponentially. Human, yes, but probably already with her IQ halved, constantly in mild pain that started to grow as the effects of the sponge antitoxin wore off. An effective demonstration, which would keep the merchant from having to infect some innocent and let things run their full course. That was done, of course, when necessary—but it wasn't good to have a long period of time when it would be obvious to the agents of the Confederacy that a sponge merchant was at large.
He wondered idly why the girl didn't commit suicide. He thought he would. A victim is probably too far gone to consider it by the time he realizes it is the only option, he decided.
Brazil looked back up at the screens. Hain had repacked the case and stored it and was preparing to go to sleep. Clever, that case, the captain thought. Sponge is extremely compressible and needs only enough seawater to keep it moist. It even grew in there, he thought. As samples were dispensed, new ones would replace it. That was the reason only the minimum was ever given to a victim—get hold of enough of it, unused, and you could grow your own.
Wu Julee was lying on her own bed, one leg
