Perhaps he had been killed just now, just entering this prison camp. Perhaps his captors had betrayed him to his death, like those ancient Earth soldiers who had lured their victims sheeplike into poisoned showers, diverting and soothing their suspicions with stone soap, until their final enlightenment burst upon them in a choking cloud. Perhaps the annihilation of his body had been so swift, his neurons had not had time to carry the information to his brain. Why else did so many antique myths agree that hell was a circular place?

Dagoola IV Top Security Prison Camp #3. This was it? This naked . . . dinner plate? Miles had vaguely visioned barracks, marching guards, daily head counts, secret tunnels, escape committees.

It was the dome that made it all so simple, Miles realized. What need for barracks to shelter prisoners from the elements? The dome did it. What need for guards? The dome was generated from without. Nothing inside could breach it. No need for guards, or head counts. Tunnels were a futility, escape committees an absurdity. The dome did it all.

The only structures were what appeared to be big gray plastic mushrooms evenly placed about every hundred meters around the perimeter of the dome. What little activity there was seemed clustered around them. Latrines, Miles recognized.

Miles and his three fellow prisoners had entered through a temporary portal, which had closed behind them before the brief bulge of force dome containing their entry vanished in front of them. The nearest inhabitant of the dome, a man, lay a few meters away upon a sleeping mat identical to the one Miles now clutched. He turned his head slightly to stare at the little party of newcomers, smiled sourly, and rolled over on his side with his back to them. Nobody else nearby even bothered to look up.

"Holy shit," muttered one of Miles's companions.

He and his two buddies drew together unconsciously. The three had been from the same unit once, they'd said. Miles had met them bare minutes ago, in their final stages of processing, where they had all been issued their total supply of worldly goods for life in Dagoola #3.

A single pair of loose gray trousers. A matching short-sleeved gray tunic. A rectangular sleeping mat, rolled up. A plastic cup. That was all. That, and the new numbers encoded upon their skins. It bothered Miles intensely that their captors had chosen to locate the numbers in the middle of their backs, where they couldn't see them. He resisted a futile urge to twist and crane his neck anyway, though his hand snaked up under his shirt to scratch a purely psychosomatic itch. You couldn't feel the encode either.

Some motion appeared in the tableau. A group of four or five men approaching. The welcoming committee at last? Miles was desperate for information. Where among all these countless gray men and women—no, not countless, Miles told himself firmly. They were all accounted for here.
