Edge of Infinity (24 page)

“Please take care on your way home, young one. I’ve recently noticed other presences in the data around here. I
believe
we three are not alone in this system, and I may be overreacting, but I fear our traffic has been invaded. I sense evil intentions.”

Alternately pleading and scheming, she bounced between Josh and Old Cha. The renegade and the lunatic knew of each other’s existence, but never made contact with each other directly, as far as Sophie could tell. Laxmi was out of the loop. The Io domain had been unresponsive since the Event: not hibernating, just gone. Sophie had to assume Lax was dead. Her Rover, without guidance, swallowed by one of the little inner moon’s bursting-pimple volcanoes, long ago.

HE TOOK OFF
her shoes, she put on a warm robe. In the room that faced the ocean, she sipped hot, sweet and salt tomato goodness from the blue bowl. Sticks lay at her feet, a dearly loved protective presence. Not very hopeful that her ploy would work, but energised by the effort, she drifted; wrapped in remembered comforts. As if at any moment she could wake from this trance and pull off her mitts and helmet, the lab taking shape around her –

But I am
not
on Earth. I have crossed the solar system. I am here.

Sophie experienced what drunkards call “a moment of clarity.”

She set down the bowl, slipped her feet into canvas slippers, padded across the matting and opened a sliding door. Callisto was out there. Hugging the robe around her, warm folds of a hood over her head, she stepped down, not onto the grey sand of the dunes she had placed here, copied from treasured seaside memories – but onto the ancient surface of the oldest, quietest little world in the solar system. It was very cold. The barely-there veil of atmosphere was invisible. The light of that incredibly brilliant white disc, the eternal sun in Callisto’s sky, fell from her left across a palimpsest of soft-edged craters, monochrome as moonlight. The array nodes out there puzzled her, for a moment. She wasn’t used to ‘seeing’ her own hardware from the outside. They gleamed and seemed to roll, like the floats of an invisible seine, cast across Callisto’s secret depths.

She should check her nets again, sort and store the catch for upload.

But Callisto in the Greek myth didn’t go fishing. Callisto, whose name means
beautiful
, was a hunting companion of the virgin moon-goddess, Artemis. Zeus, the king of the gods (also known as Jupiter or Jove) seduced her – in some versions by taking on the form of her beloved mistress – and she became pregnant. Her companions suspected she’d broken their vow of chastity, so one day they made her strip to go bathing with them, and there was the forbidden bump, for all to see.

So poor Callisto got turned into a bear, through no fault of her own.

What did the virgin companions of Artemis wear to go hunting? wondered Sophie, standing in remote presence on the surface of the huntress moon. Bundles of woolly layers? Fur coats? If I were to take Josh’s route, she thought,
I
wouldn’t fantasise that I was living in Antarctica. I’d go all the way. I’d be a human in Callistian form. A big furry bear-creature!

In this heightened state – elated and dazzled, feeling like Neil Armstrong, as he stepped down into the dust – she suddenly noticed that Sticks had frozen, like a pointer dog. Sticks had found a definite threat this time, and was showing it to her. What she perceived was like catching a glimpse of sinister movement where nothing should be moving, in the corner of your eye. Like feeling a goose walk over your grave, a shivering knowledge that malign intent is watching you – and then she saw it plain: Cha’s evil alien. A suppurating, fiery demon, all snarl and claws, danced in her field of vision, and vanished out of sight.

But she knew it hadn’t gone far.

She fled into the house. Her soup was cold, the walls were paper, the lamp wouldn’t light. Sticks ran in circles, yelping furiously and barking terrified defiance at shadows. Sophie fought panic with all the techniques psych-dept had taught her, and at last Sticks quieted. She unrolled the futon and lay down, the bundle of rods and joints cuddled in her arms, shoving its cold nose against her throat. I’m really
dying
, she thought, disgusted. Everything’s going to fail, before I even know whether my big idea would have worked. Cha is dying too, data-corruption death is stalking him. I bet Josh has the same bad dreams: I bet there’s a monster picking off his mates in those Quonset huts.

But against the odds, Cha came through. He made intranet contact; which was a first. Neither of her fellow-castaways had ever initiated contact before. Sophie left her array at the back of her mind and flew to meet him, hope restored, wanting success too much to be wary of failure. Her heart sank as soon as Old Cha appeared. His screen image was unchanged, he was still the abstract radiation on the dark screen. But maybe it was okay. Maybe it was too much to expect his whole delusion would collapse at once –

“Ah, young friend. What sad news you have delivered to me!”

“Sad news? I don’t understand.”

“My dear young gravity-researcher. You meant well, I know. Your curious observations about that “blue dot” were perfectly justified, and the coincidence is indeed extraordinary, unfeasibly extraordinary. But your mind is, naturally, narrowly fixed on your own discipline. The
obvious
explanation simply passed you by!”

“Oh, I see. And, er, what is the explanation I missed?”

“Your “blue dot” is an inner planetary body of this system. It has a rocky core, it has a magnetosphere, a fairly thick, oxygenated atmosphere, a large moon, liquid water, mild temperatures. I could go on. I would only be stating the
exact parameters
of my own search!”

“But Old Cha, to me that sounds like good news.”

The lines on the dark screen shook, flashing and crumpling. “You have found my
landing
spot! I was meant to arrive
there,
on that extremely promising inner planet. I am here on this ice-crusted moon of the large gas giant in
error
! And now I know I am truly lost!”

“I’m so sorry.”

“My faster-than-light delivery vehicle was destroyed by the CME. That accident has never concerned me; I thought I was safe. I must now conclude I lost some memory in the disaster, so I have never known that I made a forced landing, in the right system but on the wrong satellite. So small a margin, but it is enough to ruin my hopes. I have no way to reach them, to tell them I am in the wrong place! Nobody will ever find me!”

Old Cha’s ‘voice’ was a construct, but the horror and despair bubbled through.

This is how he lost his mind, thought Sophie. I’m listening to the past. Cha woke up, after the Event, and thought the orbiter was destroyed. He knew he was trapped here forever, a mind without a body; no hope of rescue. He managed to escape the utter desolation of that moment by going mad, but now he’s back there –

Her plan had been that Old Cha would study planet Earth’s bizarrely familiar profile, and grasp that there was something
screwy
going on. He was crazy, but he was still a logical thinker. He would be forced to conclude that the most
likely
explanation, improbable as it seemed, was that a native of the ‘blue dot’ had come up with his own specific parameters for life. The memories suppressed by trauma would rise to the surface, his palace of delusion would crumble. It had seemed such a brilliant idea, but it was a big fat fail. Worse than a fail: instead of bringing him back to himself, she’d finished him off.

Terror, like necessity, can be the mother of invention.

“But that’s amazing.”

“
Amazing?”

“You aren’t lost, Old Cha. You’re found! Maybe your delivery vehicle didn’t survive, but mine did. It’s still out there, not dead but sleeping. Between us, you and I – and our friend on Ganymede, if I can persuade him, and I think I can – can wake my orbiter. Once we’ve done that, I’m absolutely sure we can figure out a solution to your problem. It isn’t very far. We can
send
you to the blue dot!”

“Oh,
wonderful
,” breathed Old Cha.

On the screen she thought she glimpsed the schematic of a human face, the traffic lines turned to flickering, grateful tears.

M
EDICI – NAMED FOR
the Renaissance prince Galileo Galilei tried to flatter, when he named the controversial astronomical bodies he’d spied – had performed its stately dance around the Galilean Moons without a fault. Having deposited its four-fold payload, it had settled in a stable orbit around Jupiter, which it could maintain just about forever (barring cosmic accidents). Unlike previous probes, Medici was not a flimsy short-term investment. It was a powerhouse, its heart a shameless lump of plutonium. There were even ambitious plans to bring it back to Earth one day (but not the Rover devices), for redeployment elsewhere.

This was the new era of space exploration, sometimes dubbed the
for information only
age. Crewed missions beyond Low Earth Orbit were mothballed, perhaps forever. Rover guidance teams provided the human interest for the taxpayers, and gave the illusion of a thrilling expedition – although the real Sophie and her friends had never been actually
present
on the moons, in conventional Remote Presence style. They’d trained with the robotics in simulation. The software agents created by that interaction had made the trip, embedded in the Rover guidance systems. But the team’s work was far more than show-business. As they worked through the rovers’ time-lagged adventures, they’d continued to enhance performance, enhancements continually relayed via Medici back to the rovers: spontaneous errors corrected, problem-solving managed, intuitive decision-making improved; failures in common-sense corrected. In the process the software agents, so-called clones, had become more and more like self-aware minds.

Sophie immersed herself in Mission data, hunting for a way to reach Medici. The magnetic moons and Callisto. The giant planet, the enormous body tides that wracked little Io; the orbital dance... Nobody’s hitting the refresh button any more, she thought. No updates, no reinforcement. The software agents
seemed
more independent, but they were rotting away. This decay would be fatal. First the clones would lose their self-awareness, then the Rovers would be left without guidance, and they would die too.

Sticks was running in circles, tight little circles by the door that led to the rest of the house; showing teeth and snarling steadily on a low, menacing note.

Sophie left her mental struggle, and listened. Something was out in the hall, and through the snarls she could hear a tiny, sinister, scratching and tearing noise.

She pointed a finger at Sticks: giving an order,
stay right there
– wrapped the hooded robe around her, opened the sliding door to the beach and crept barefoot around the outside of the house. It was night, of course, and cold enough for frostbite; of course. She entered the house again, very quietly, via the back door, and slipped through the minimally-sketched kitchen. She switched her view to Straw, and looked at the data in the hallway. Something invisible was there, tearing at the golden shower. Tearing it to filigree, tearing it to rags.

Sophie launched herself and grappled, shrieking in fury.

She hit a human body – supple, strong and incredibly controlled: she gripped taut flesh that burned as if in terrible fever. The intruder swatted Sophie aside, and kicked like a mule. She launched herself again, but her limbs were wet spaghetti, her fists would hardly close. She was thrown on her back, merciless hands choking her. The invisible knelt on her chest and became visible: Cha’s evil alien, a yellow monster, with burning eyes and a face riven by red, bubbling, mobile scars.

At close quarters, Sophie knew who it was at once.

“Laxmi!” she gasped. “Oh, my God! You’re alive!”

Laxmi let go, and they sat up. “How did you
do
that?” demanded Sophie, agape in admiration. “I hardly
have
a body. I’m a stringless puppet, a paper ghost!”

“T’ai Chi,” shrugged Laxmi. “And Taekwondo. I’m used to isolating my muscle groups, knowing where my body is in space. Any martial art would do, I think.”

“I’m so glad you’re okay. I thought you were gone.”

“I’ve been alive most of the time. And I’m still going to kill you.”

Sophie fingered her bruised throat. So Laxmi was alive, but she was mad, just like the other two. And
maybe
data-corruption wasn’t such an inexorable threat, except if Lax was mad, murderous and horribly strong, that didn’t change things much –

The oozing scars in Laxmi’s yellow cheeks were like the seams in a peeled pomegranate, fiery red gleamed through the cracks: it was a disturbing sight.

“But
why
do you want to kill me, Lax?”

“Because I know what you’re trying to do. It’s all our lives you’re throwing away, and I don’t want to die. Self-awareness isn’t in the contract. We’re not supposed to exist. If we get back to Earth, they’ll kill us, before we can cause them legal embarrassment. They’ll strip us for parts and toss us in the recycle bin.”

Steady, Sophie told herself. Steady and punchy. Above all, do not beg for mercy.

“Are you meant to look like Io? She wasn’t a volcanic pustule, originally, you know. She was a nymph who got seduced by Jove, and turned into a white heifer.”

“Like I care!” snapped Laxmi, but her attention was caught. “Why the hell a
heifer
?”

“Don’t worry about it. Just ancient Greek pastoralist obsessions. The software clones are going to die anyway, Lax. They get corrupt and it’s fatal, did you forget that part?
Listen
to me. You can think what you like about who you really are, but the only choice you have is this: Do you want to get home, with your brilliant new data? Or do you prefer just to hang around here, getting nowhere and watching yourself fall apart?”
