Moonrise

He staggered back under their assault, flung Melissa aside like a rag doll and grasped one of Greg’s strangling hands. His brother was trying to choke him. Beyond his insanely twisted face, Doug could see Melissa reaching for the keyboard again.

Doug jabbed a thumb in Greg’s eye. He howled and released Doug’s throat Stepping back just enough for the leverage, Doug punched his brother in the jaw with a short, compact right Greg’s eyes rolled up and he collapsed to the stone floor.

Melissa was banging on the keyboard, desperately hoping to strike the key that would open the plasma vents to vacuum. Doug reached for her again when suddenly the big chamber seemed to erupt into a tornado. Dust swirled as Doug’s ears roared painfully.

He saw Melissa’s face, glowing with triumph, crumble into a mask of blood. Blood gushed from her ears, her eyes. Her mouth filled with blood as she twirled in the rushing air, and slid across the floor, arms flapping like a scarecrow’s.

Doug had only a moment to turn and look down at Greg, bleeding from every pore, before he too collapsed and died.

MOONBASE INFIRMARY

Douglas Scavenger was sitting up in the bed, tubes carrying whole blood, saline solution, and liquid nutrient into his arms, monitoring machines above his head blinking and displaying crawling, glowing lines that represented his heart beat, breathing rate, blood pressure. Each factor was so high that the monitors had been specially programmed so that they would not constantly be screeching their warning signals.

His mother was sitting on a hard plastic chair at the foot of the bed while Zimmerman stood beside the bed, scowling at him.

“The nanomachines have raised your metabolic rate by a factor of nearly three,” he muttered. “I don’t understand it.”

Joa

“Yah, but how ?” Zimmerman insisted. “How did they do it?”

“Don’t ask me,” said Doug. “One moment I was passing out in the EVC. The next thing I knew, I woke up here in the infirmary.”

Still scowling, Zimmerman mumbled, “They must have shut down your heart rate to lower your blood pressure and prevent ruptures of the capillaries.”

“How did they know to do that?” Doug asked.

Zimmerman looked down at him. “How did they make the decision to suspend your heart function? Did they simply react to the immediate physical stimulus, or…’ His voice trailed off.

“Or what?” Joa

With a shake of head hard enough to make his jowls waddle,

Zimmerman continued, “Or did they make an assessment that it was safer to shut down your heart than to allow your capillaries to burst?”

“Make an assessment?” Doug echoed. “Like they’re intelligent?”

“No, that ca

“The bugs must have reacted to the immediate stimulus, as you said,” Doug suggested.

“Yah. Perhaps. And yet—

“Whatever they did,” Joa

“By stopping my heart and killing me.”

Zimmerman seemed lost in thought. “They are either very stupid, or much more intelligent than I had ever thought possible.”

He reached for the curtain screening off Doug’s bed, muttering, “I must talk to Kristine about this. This is very unexpected.”

Without another word to Doug or his mother, Zimmerman stepped out of the cubicle.

For several moments Doug simply lay in his bed, silent, looking at his mother’s sad, abstracted face. Finally, he said, “It’s a shame we couldn’t save Greg.”

Joa

Doug’s last conscious memory of them flashed through his mind. Blood spurting everywhere, their final strangling, gargling shrieks.

“And Bianca Rhee was killed too?”

His mother nodded. “No one seems to know what she was doing out in the garage. They found her in a spacesuit but she had already died of heart failure.”

“From the bends.”

“Yes, nitrogen bubbles blocked her heart valves.”

Leaning his head back against the pillows, Doug wished he could feel something. Some emotion. Sorrow. Pain. Even relief. Nothing. Just a blank emptiness inside him. As if the nanomachines that had saved his life had also taken away his soul.

His mother still looked stricken. Nearly twenty years she’s protected Greg and now he’s dead. He killed himself and I couldn’t stop him. I tried and failed. He killed my father and Melissa and Bianca. And himself. And I couldn’t prevent it.

“It’s not your fault,” Joa

“What?”

“It’s not your responsibility. Greg would have killed himself sooner or later. I know that. I suppose I’ve known it all along.”

“If I had just been a little faster—”

“No,” Joa

“He opened the plasma vents to vacuum,” Doug said. “He wanted to kill us all. That’s what he said.”

“What Greg really wanted was to kill himself.”

“I should’ve stopped him.”

“Ji

Bianca died, though, Doug said to himself. I’ll have to go out to the main garage and find her ballet slippers. They must be back in the screened-in area where she practices. Then he corrected himself: practiced. Past tense. She’s dead.

He closed his eyes for what seemed like a moment, but when he opened them again his mother was gone and the tubes had been disco

“You’re awake?” It was his mother again. This time Lev Brudnoy stood beside her, tall and gangling but looking neater, straighter than Doug remembered him. His beard was nicely trimmed, his hair combed. Instead of coveralls he was wearing dark slacks and a deep green turtleneck shirt Joa

“We’re heading back to Sava

“We?” Doug asked. “The two of you?”

“Yes,” said Brudnoy.

His mother added, “Lev and I have become…very close, over the past few days.”

Brudnoy actually blushed.

Doug tried to make a smile for them, and hoped it worked. “Why Sava

“To pick up the pieces,” she replied. “I’ve got to make certain that the board of directors doesn’t try to hinder the repairs we need here. And I want to push your diamond Clippership project.”

Doug guessed, “Ji

“Yes. I may have to get myself elected to board chairman again,” Joa

“I understand,” Doug said.

“Zimmerman and Kris Cardenas are staying. They’ll be able to help you.”

“I understand,” Doug repeated.

And he did. Joa

By the time they were ready to go out to the rocket port, Doug was strong enough to get out of bed and go with them. The medics argued against it, but the monitors showed that his metabolic rate was stable and his weight — down nearly five pounds a few days earlier — was almost back to normal.

Doug watched their liftoff from his favorite perch, in the tiny observation blister of the rocket port. The big, ungainly LTV was there one instant, and an instant later it was gone in a cloud of aluminum oxide smoke.
