Stupid girl,she told herself. She was dehydrated. Eight days without activity was more than enough to start atrophy. At least she should have stretched out.

She massaged her stiff muscles until the knots were gone, then stretched, focusing her mind like she was back in dojo. When she was in control of her body, she kicked again. And again. And again, until light started to show through the edges of the locker. And again, until the door was so bent that the three hinges and the locking bolt were the only points of contact between it and the frame.

And one last time, so that it bent far enough that the bolt was no longer seated in the hasp and the door swung free.

Julie shot from the locker, hands half raised and ready to look either threatening or terrified, depending on which seemed more useful.

There was no one on the whole deck level: the airlock, the suit storage room where she’d spent the last eight days, a half dozen other storage rooms. All empty. She plucked a magnetized pipe wrench of suitable size for skull cracking out of an EVA kit, then went down the crew ladder to the deck below.

And then the one below that, and then the one below that. Personnel cabins in crisp, almost military order. Commissary, where there were signs of a struggle. Medical bay, empty. Torpedo bay. No one. The comm station was unmanned, powered down, and locked. The few sensor logs that still streamed showed no sign of the Scopuli.A new dread knotted her gut. Deck after deck and room after room empty of life. Something had happened. A radiation leak. Poison in the air. Something that had forced an evacuation. She wondered if she’d be able to fly the ship by herself.

But if they’d evacuated, she’d have heard them going out the airlock, wouldn’t she?

She reached the final deck hatch, the one that led into engineering, and stopped when the hatch didn’t open automatically. A red light on the lock panel showed that the room had been sealed from the inside. She thought again about radiation and major failures. But if either of those was the case, why lock the door from the inside? And she had passed wall panel after wall panel. None of them had been flashing warnings of any kind. No, not radiation, something else.

There was more disruption here. Blood. Tools and containers in disarray. Whatever had happened, it had happened here. No, it had started here. And it had eneded behind that locked door.

It took two hours with a torch and prying tools from the machine shop to cut through the hatch to engineering. With the hydraulics compromised, she had to crank it open by hand. A gust of warm wet air blew out, carrying a hospital scent without the antiseptic. A coppery, nauseating smell. The torture chamber, then. Her friends would be inside, beaten or cut to pieces. Julie hefted her wrench and prepared to bust open at least one head before they killed her. She floated down.

The engineering deck was huge, vaulted like a cathedral. The fusion reactor dominated the central space. Something was wrong with it. Where she expected to see readouts, shielding, and monitors, a layer of something like mud seemed to flow over the reactor core. Slowly, Julie floated toward it, one hand still on the ladder. The strange smell became overpowering.

The mud caked around the reactor had structure to it like nothing she’d seen before. Tubes ran through it like veins or airways. Parts of it pulsed. Not mud, then.

Flesh.

An outcropping of the thing shifted toward her. Compared to the whole, it seemed no larger than a toe, a little finger. It was Captain Darren’s head.

“Help me,” it said.

Ahundred and fifty years before, when the parochial disagreements between Earth and Mars had been on the verge of war, the Belt had been a far horizon of tremendous mineral wealth beyond viable economic reach, and the outer planets had been beyond even the most unrealistic corporate dream. Then Solomon Epstein had built his little modified fusion drive, popped it on the back of his three-man yacht, and turned it on. With a good scope, you could still see his ship going at a marginal percentage of the speed of light, heading out into the big empty. The best, longest funeral in the history of mankind. Fortunately, he’d left the plans on his home computer. The Epstein Drive hadn’t given humanity the stars, but it had delivered the planets.

Three-quarters of a kilometer long, a quarter of a kilometer wide-roughly shaped like a fire hydrant-and mostly empty space inside, the Canterburywas a retooled colony transport. Once, it had been packed with people, supplies, schematics, machines, environment bubbles, and hope. Just under twenty million people lived on the moons of Saturn now. The Canterburyhad hauled nearly a million of their ancestors there. Forty-five million on the moons of Jupiter. One moon of Uranus sported five thousand, the farthest outpost of human civilization, at least until the Mormons finished their generation ship and headed for the stars and freedom from procreation restrictions.

And then there was the Belt.

If you asked OPA recruiters when they were drunk and feeling expansive, they might say there were a hundred million in the Belt. Ask an inner planet census taker, it was nearer to fifty million. Any way you looked, the population was huge and needed a lot of water.

So now the Canterburyand her dozens of sister ships in the Pur’n’Kleen Water Company made the loop from Saturn’s generous rings to the Belt and back hauling glaciers, and would until the ships aged into salvage wrecks.

Jim Holden saw some poetry in that.

“Holden?”

He turned back to the hangar deck. Chief Engineer Naomi Nagata towered over him. She stood almost two full meters tall, her mop of curly hair tied back into a black tail, her expression halfway between amusement and annoyance. She had the Belter habit of shrugging with her hands instead of her shoulders.

“Holden, are you listening, or just staring out the window?”

“There was a problem,” Holden said. “And because you’re really, really good, you can fix it even though you don’t have enough money or supplies.”

Naomi laughed.

“So you weren’t listening,” she said.

“Not really, no.”

“Well, you got the basics right anyhow. Knight’s landing gear isn’t going to be good in atmosphere until I can get the seals replaced. That going to be a problem?”

“I’ll ask the old man,” Holden said. “But when’s the last time we used the shuttle in atmosphere?”

“Never, but regs say we need at least one atmo-capable shuttle.”

“Hey, Boss!” Amos Burton, Naomi’s earthborn assistant, yelled from across the bay. He waved one meaty arm in their general direction. He meant Naomi. Amos might be on Captain McDowell’s ship; Holden might be executive officer; but in Amos Burton’s world, only Naomi was boss.

“What’s the matter?” Naomi shouted back.

“Bad cable. Can you hold this little fucker in place while I get the spare?”

Naomi looked at Holden, Are we done here?in her eyes. He snapped a sarcastic salute and she snorted, shaking her head as she walked away, her frame long and thin in her greasy coveralls.

Seven years in Earth’s navy, five years working in space with civilians, and he’d never gotten used to the long, thin, improbable bones of Belters. A childhood spent in gravity shaped the way he saw things forever.

At the central lift, Holden held his finger briefly over the button for the navigation deck, tempted by the prospect of Ade Tukunbo-her smile, her voice, the patchouli-and-vanilla scent she used in her hair-but pressed the button for the infirmary instead. Duty before pleasure.

Shed Garvey, the medical tech, was hunched over his lab table, debriding the stump of Cameron Paj’s left arm, when Holden walked in. A month earlier, Paj had gotten his elbow pinned by a thirty-ton block of ice moving at five millimeters a second. It wasn’t an uncommon injury among people with the dangerous job of cutting and moving zero-g icebergs, and Paj was taking the whole thing with the fatalism of a professional. Holden leaned over Shed’s shoulder to watch as the tech plucked one of the medical maggots out of dead tissue.
