Part 7 (1/2)

”Tling and I have begged him.” Her voice was faint. ”But he feels commanded.”

”By his nanorobs? Can't he think of you and Tling?”

Her answer took a long time to come.

”You don't understand them.” She seemed composed again; I wondered if her own nanorobs had eased her pain. ”You may see them as micromachines, but they don't make us mechanical. We've kept all the feelings and impulses the primitives had. The nanorobs simply make us better humans. Sandor is going not just for the colonists, but for me and Tling, for people everywhere.”

”If the odds are as bad as they look-” Casey squinted doubtfully. ”What can one man hope to do?”

”Nothing, perhaps.” She made a bleak little shrug. ”But he has an idea. Long ago, before he ever left Earth to search for his brother, he worked with his mother on her nanorob research. He has reprogrammed himself with the science. If the killer is some kind of virulent organism, he thinks the nanorobs might be modified into a s.h.i.+eld against it.”

”Speak to him,” Casey begged her. ”Get him to take us with him. We'll help him any way we can.””You?” Astonishment widened her eyes. ”How?”

”We put you here on Earth,” he told her. ”Even with no nanorobs at all.”

”So you did.” Golden color flushed her skin. ”I'll speak to him.” Silent for a moment, she shook her head. ”Impossible. He says every seat on the s.h.i.+p is filled.”

She paused, frowning at the ceiling. The robot was moving around the table, offering a bowl of huge flesh-colored mushrooms that had a tempting scent of frying ham.

”We are trying to plan a future for Tling.” Her face was suddenly tight, her voice hushed with feeling. ”A thousand years will pa.s.s before he gets back. He grieves to leave Tling.”

”I saw her this morning,” I said. ”She's terribly hurt.”

”We are trying to make it up. I've promised that she will see him again.”

Pepe looked startled. ”How can that happen?”

She took a mushroom, sniffed it with a nod of approval, and laid it on her plate.

”We must plan the time,” she told him. ”Tling and I will travel. I want to see what the centuries have done to my own homeworld. It will take careful calculation and the right star flights, but we'll meet him back here on the date of his return.”

”If-”

Casey swallowed his voice. Her face went pale, but after a moment she gave us a stiff little smile and had the robot offer the mushrooms again. They had a name I never learned, and a flavor more like bittersweet chocolate than ham. The meal ended. She left us there alone with the robots, with nowhere to go, no future in sight.

”A thousand years!” Pepe muttered. ”I wish we had nanorobs.”

”Or else-”

Casey turned to the door.

”News for you.” Lo stood there, smiling at us. ”News from the emigrant s.h.i.+p. Uneasy pa.s.sengers have arranged for new destinations, leaving empty places. Sandor has found seats for you.”

7.

Sandor took us to our seats on the emigrant s.h.i.+p. Wheel-shaped and slowly spinning, it held us to the floors with a force weaker than Earth's gravity, stronger than the Moon's. A blue light flashed to warn us of the s.p.a.ce-time slide. Restraints folded around us. I felt a gut-wrenching tug. The restraints released us.

With no sense of any other change, we sat uneasily waiting.

The big cabin was hushed. Watching faces, I saw eager expectation give way to disappointment and distress. I heard a baby crying, someone shouting at a robot attendant, then a rising clamor of voices at the brink of panic. Sandor sat looking gravely away till I asked him what was wrong.”We don't know.” He grinned at our dazed wonderment. ”At least we've made the skip to orbit. Five hundred light-years. You're old men now.”

He let us follow him to the lounge, where a tall ceiling dome imaged a new sky. The Milky Way looked familiar. I found the Orion Nebula, but all the nearer stars had s.h.i.+fted beyond recognition. I felt nothing from the s.h.i.+p's rotation; the whole sky seemed to turn around us. Two suns rose, set close together. One was yellow, smaller and paler than our own, the brighter a hot blue dazzle. The planet climbed behind them, a huge round blot on the field of unfamiliar stars, edged with the blue sun's glare. Looking for the glow of cities, all I saw was darkness.

Anxious pa.s.sengers were cl.u.s.tering around crew members uniformed in the s.h.i.+p's blue-and-gold caps and sashes. Most of their questions were in the silent language of the nanorobs, but their faces revealed dismay. I heard voices rising higher, cries of shock and dread.

We turned to Sandor.

”The telescopes pick up no artificial lights.” His lean face was bleakly set. ”Radio calls get no answer.

The electronic signal spectrum appears dead.” He shook his head, with a heavy sigh. ”I was thinking of my brother. I'd hoped to find him here.”

With gestures of apology to us, uneasy people pushed to surround him. He looked away to listen, frowning at the planet's dark shadow, and turned forlornly to go. He spoke his final words for us.

”We'll be looking for survivors.”

We watched that crescent of blue-and-orange fire widen with each pa.s.sage across the ceiling dome till at last we saw the planet's globe. Swirls and streamers of high cloud shone brilliantly beneath the blue sun's light, but thick red dust dulled everything under them.

One hemisphere was all ocean, except for the gray dot of an isolated island. A single huge continent covered most of the other, extending far south of the equator and north across the pole. Mountain ranges walled the long west coast. A single giant river system drained the vast valley eastward. From arctic ice to polar sea it was all rust-red, nothing green anywhere.

”A rich world it must have been.” Sandor made a dismal shrug. ”But now-?”

He turned to nod at a woman marching into the room. A woman so flat-chested, masculine, and strange that I had to look twice. Gleaming red-black scales covered her angular body, even her hairless head.

Her face was a narrow triangle, her chin sharply pointed, her eyes huge and green. We stared as she sprang to a circular platform in the center of the room.

”Captain Vlix,” he murmured. ”She's older than I am, born back in the days when nanorobs were new and body forms experimental. I sailed with her once. She remembered my brother asking if she knew me. That was Earth centuries ago. She had no clues to give me.”

Heads were turning in attention. I saw uneasy expectation give way to bitter disappointment. Sandor stood frozen, widened eyes fixed on her, till she turned to meet another officer joining her on the platform. They conferred in silence.

”What is it?” Casey whispered. Sandor seemed deaf till Casey touched his arm and asked again, ”What did she say?”

”Nothing good.” Sandor turned to us, his voice hushed and hurried. ”She was summing up a preliminary report from the science staff. This dead planet is the second they have reached. The other was twohundred light-years away. The implications-”

He hunched his shoulders, his skin gone pale.

”Yes? What are they?”

With a painful smile, he tried to gather himself.

”At this point, only speculation. The killer has reached two worlds. How many more? Its nature is not yet known. The science chief suggests that it could possibly be a malignant nanorob, designed to attack all organic life. It certainly seems aggressive, advancing on an interstellar front from the direction of the galactic core.”
