Moonrise

“Dead?”

Paul felt as if he had stumbled into a leper colony. He didn’t want to touch anything, get near anyone.

Forcing himself to be as calm as possible, he said to Tinker, “Something’s gone wrong with the nanobugs. They’ve infected Wojo’s suit and eaten away the insulation.”

“His suit failed?” Tinker’s voice went hollow with sudden fear.

The goddamned bugs are chewing up his body, Paul knew. But there was no sense scaring Tinker more than he had to.

“Did you handle anything from the tractor?” Paul asked again. “Or the hopper?”

Sounding confused, Tink said, “I looked over Wojo’s shoulder — God, is he really dead?”

“Did you touch anything?”

“He… he showed me a piece of tubing that had broken down. I looked it over.”

“Did you touch it?”

“Yes! Of course I touched it.”

“Get back inside the shelter and get out of that damned suit as fast as you can,” Paul commanded. “Shove the suit into the airlock and stay inside the shelter until I can get some help here.”

“I don’t understand,” Tinker said.

“Your suit’s infected with nanobugs that attack carbon-based molecules,” Paul said, a

“Carbon-based molecules? That includes me!”

“Damned right! Get out of that fuckin’ suit as fast as you can!”

Tinker ducked back through the airlock at last. Paul stood frozen with terror, staring at Wojo’s fallen body. His spacesuit was disintegrating before his eyes. In the soft light from Earth overhead, Paul watched as the arms of Wojo’s suit slowly disappeared, layer by layer: fabric, insulation, the neoprene gaslight bladder. They’ll be down to his skin and flesh; like maggots.

Tinker’s first scream turned Paul’s blood cold. Tink either hadn’t taken off his helmet, or he had left his suit radio on while he was getting out of the spacesuit. Either way, Paul heard him screaming and screaming and screaming. Wojo had died of decompression when the bugs had eaten through his suit. Tinker was devoured alive, screaming until his voice went hoarse.

Paul stood alone out on Mare Nubium, his two companions dead, the area infested with killing nanobugs, the nearest shelter twenty miles away.

Greg, he knew. Greg’s done this. He’s the only one who would even think of it Slipped a sampling of gobblers in with the assemblers. He’s trying to murder me. He’s killed Wojo and Tink. I’m next. If I let him.

SHELTER 19

Paul was struggling with an invisible demon. He couldn’t see it, but he could feel it clutching at his throat, tearing at his flesh. He thrashed madly, grappling with it, trying with every ounce of strength in him to push it away, to get it off him.

His eyes snapped open. Above him curved the rounded ceiling of Tempo 19. Air circulation fans hummed softly and a pump chugged faithfully in the background.

I’m safe, he told himself, lying in his sweaty coveralls on the bunk. I’m okay. For how long?

“Long enough,” he said, his voice a grating, harsh rasp. Wincing when he put his weight on his right foot, he limped to the food freezer and microwave oven that comprised the shelter’s galley. The sink was beside it. Paul took a plastic cup from the rack over it and filled it with water. He drank it down slowly; it was warm and flat and the best drink he had ever tasted. He savored it, relished it, gloried in the way it eased the sandpaper feeling in his throat.

He pulled out a plastic container of frozen soup and popped it into the microwave. Then he limped to the communications console and called Moonbase.

Impatiently he reported the deaths of Wojo and Tinker. The guy on comm duty quickly called the base’s director, and Paul had to repeat the news to her.

“The nanomachines killed them?” her hard-bitten face radiated surprise, disbelief.

“And damned near killed me, too,” Paul said wearily. “Now patch me through to Sava

“Just a minute,” said the base director. “I need to know a lot—”

“Later,” said Paul, putting iron into it. “I want to talk to my wife. Now. On a private link.”

“Okay,” the director said. I’ll put together a team to go out there and get the bodies.”

“No! Nobody goes anywhere near that site until I’ve had a talk with the San Jose troops. That whole area is quarantined as of now,”

The director’s eyes went wide for a moment. Then she nodded. “Understood.”

Paul was glad that Joa

She was smiling as her face appeared on the tabletop display screen before Paul, but her smile froze the instant she saw his haggard, bleary-eyed face.

“Paul, what’s happened?”

He had spent twenty minutes setting up a direct laser link to Sava

“Greg tried to murder me,” he said, then waited three seconds for the shock to register in her face.

“Greg? How…?”

“He put a mix of gobblers in with the nanobug assemblers. Two men were killed and he damned near got me.”

“Gobblers?” Joa

“Nanobugs that take molecules apart. Long-chain carbon molecules. Like spacesuit materials. Like human flesh.”

Joa

“There’s a tractor outside this shelter. I’m going to ride back to Moonbase and then head home.”

He could see the conflicting emotions battling within her. “What should I do? About Greg, I mean?”

“Nothing!” Paul snapped. “Stay away from him. He’s a murderer and I don’t want him anywhere near you.”

Joa

That’s the long and the short of it, Paul told himself. I’m her Husband, the father of the child she’s carrying. But Greg is her son and she’ll try to protect him even if he tries to kill her.

I’ve got get back there, he realized. Quick as I can. Got to get there and protect her.

Joa

Without consciously thinking about it, she tapped the phone console on her desk and called out her son’s name. In a few seconds Greg’s darkly handsome face appeared on the display screen.

“Could you come over to my office, Greg?” Joa

“I’m in the middle of—”

“Right now,” Joa

A

He looked more apprehensive than a

Warily, with the same expression he had worn as a little boy when he’d been caught doing something he shouldn’t, Greg walked across the richly patterned Indian carpet and took the leather chair in front of Joa

“What’s happened?” he asked softly.

“I just got a call from Moonbase,” said Joa

His brows rose. “Oh?”

“It was Paul. He’s still alive, but the two men working with him were killed.”

Greg let out a long sigh. “Too bad.”

“The nanomachines killed them.”

“Yes.”

“You know all about it,” don’t you?”

“Nanotechnology is very new, Mom. Untried. Accidents will happen.”

Joa

“That’s just like him.”

“Did you use nanomachines to kill Brad?” Joa
