A
S THE BUS
set off across the compound, Joshua noticed, military vehicles moved quietly into formation ahead and behind, including a couple of motorcycle outriders. Lobsang pointed up, and Joshua saw through skylights a beefy-looking military twain hovering overhead.
âThe security seems heavy,' Joshua remarked to Maggie.
âWell, we continue to get plenty of threats here. Though I hope my response is more subtle than my predecessor's. I'm confident we've got security buttoned up tight enough.'
But for all Maggie Kauffman's evident competence, Lobsang and Joshua shared a sceptical glance. And again Lobsang looked meaningfully at the smiling, relaxed face of Douglas Black, huge in the wall screen.
As they passed through the boundary security and rolled out of Little Cincinnati, the landscape outside the window soon became utterly alien.
They were heading east, Joshua saw from the position of the sun â it was about noon, the sun was to the south. The roadway they followed was a straight dirt track, evidently purposely left clear so that traffic like this could pass. But to either side of the track, the substance of the Thinker towered. They drove between diamond cliffs, their very surfaces complex textures of facets and panels. The material was mostly clear, it really was like quartz or diamond, and the captured sunlight, multiply reflected, emerged as a cool-blue glow. Joshua had crossed Earths trapped in Ice Ages; very old ice could look like this, he knew, shining like walls of blue light. Yet he glimpsed structure in there producing light of its own, winking stars like trapped constellations. Every so often they drove
over
structures crossing the road, like speed bumps but with more texture â fallen glassy pillars. And more prosaically the bus and its accompanying fleet had to skirt those huge heat-release pits in the ground, circular shafts lined with concrete.
Lee Malone came back to speak to them, though at Maggie's stern glare she sat down and strapped herself in. She held up the component she'd shown them before. âI'll be installing this later.' A slab of crystal, winking lights. âYou can see why we call this machine the Thinker. Every gram of it is devoted to information processing â to intelligence.'
âAnd we're driving
through
it,' Joshua said. âAs if we're driving through an immense brain. What the hell is it doing with all that brainpower?'
They came to a place where the engineered landscape seemed to have split along a tremendous fault. The bus slowed, and the passengers peered out at an uplifted cliff that rose a good fifty yards above the level of the road. The edge looked fractured, and sparks, like miniature lightning flashes, crackled across the broken face. But Joshua saw connections, scab-like extrusions, seeping down the uplifted face to the lower levels. A healing process beginning, perhaps. Something about it made Joshua shudder.
âEarthquake,' Maggie said. âA small one, but it did a lot of damage. Well, I say a lot â minor on the Thinker's overall scale. You'll see it seems to be repairing itself. We did send human crews out here, but they didn't know where to start.'
Joshua, staring at the computronium cliff, thought he saw movement, short noon-time shadows shifting across the broken faces. âI could swear I see somebody moving.'
âCould be.' Maggie snapped her fingers to attract the attention of a junior officer, who began to make calls. âThis is a machine as big as a continent, Joshua. We've had people trying to
mine
the stuff â there is gold in there, platinum. It's hard to patrol it all, although we do try. Drive on, Dev.'
The scenery soon became numbing. The scale was literally superhuman, after all.
Joshua's head started to nod. The troll
did
fall asleep, and snored enthusiastically.
After around an hour, the bus slowed. Dev Bilaniuk announced they were arriving at Hillsboro â or, rather, a station at the footprint of that Datum community. They drove into another fenced compound, much smaller than Little Cincinnati, just a few acres kept clear of obvious Thinker elements. At the heart of this facility was another wire fence enclosing a much smaller area, with its own watchtowers and marines hefting automatic weapons. Joshua wondered what secret they were guarding here.
And just beyond, not much further to the east, Joshua saw open countryside. The crystalline layers of computronium that washed around this compound came to a ragged border; this was an edge of the Thinker.
âEverybody out,' Maggie said as the bus rolled to a halt. âThere'll be coffee, food. I'd advise you to use the bathroom on the bus, however; the local facilities as used by marine jarheads and Navy grunts aren't likely to be pristine . . .'
Joshua clambered out of the bus with some difficulty, refusing help. Standing with Lobsang, leaning on his stick, he accepted a coffee.
On the side of the empty bus, a panel was alight with the image of Douglas Black, his head cradled on what looked like fresh pillows. When he saw Lobsang, he made a gesture from Joshua's distant childhood, forked fingers pointing to his own eyes, then outward.
I'm watching you.
Black grinned boyishly.
Maggie was intrigued by Lobsang. âYou're drinking the coffee?'
âFor the flavour, and to be sociable. I can ape most human functions.'
âI've ordered food and drink for the troll,' Maggie said. âA variety. I'm used to provisioning my own troll crew members. I know they're picky.'
âSancho isn't too choosy,' Joshua said. âDon't give him caffeine, however. I tried him on an espresso once. Boy, did I regret that!'
An officer came jogging up. âThe lollipops are ready for you, ma'am.'
Joshua and Lobsang exchanged a glance. Lollipops? That word had only one meaning for Joshua, and not a pleasant one.
Maggie led them to the central wired-off compound. âJust to warn you, what you're going to see is a Next project, not ours. I'm told the individuals involved, or at least their parents, had a free choice about participating. Try not to judge what you see, not to react . . .'
The two Next sat in chairs, facing each other; they had metal frames helping support their heads, and drip tubes snaked into their bare arms. Their bodies seemed almost normally proportioned, and they were dressed in light robes, like hospital gowns. But their heads were grotesquely swollen, the craniums all but hairless, the big bubble-like skulls overwhelming their small faces. They were evidently a male and female, but it was hard to guess at their ages.
Attendants stood by this tableau, whether Next or human Joshua couldn't have said. But the guards around the wire fence were US marines.
Lollipops
. The memory surfaced slowly. It was forty years ago now. Joshua and Lobsang, during The Journey, had paused at a world more than a hundred and thirty thousand steps from the Datum. Here they had found evidence of a slaughter of human colonists . . . And, later, a very strange creature. Trying to help the big-brained elf as she gave birth, in his ignorance Joshua could have killed her.
The creatures in the pen were like Joshua's lollipops, crossed with humans.
Roberta Golding joined them, walking over from the bus. âThey are in no pain.'
Joshua frowned. âWhy do you say that?'
âIt's the first question people usually ask.'
âAnd why the guards?'
Maggie said grimly, âThey're here because people have tried to terminate these two. Even some of our own personnel.'
Roberta said, âThe marines protect Ronald and Ruby from such misguided acts of kindness.'
Joshua stared. âRonald and Ruby?'
âThey have been genetically engineered, based on a humanoid type you yourself discovered, Joshua Valientéâ'
âWhat the hell are they doing here?'
Roberta sighed. âWe are trying to communicate with the Thinker. It was Ronald and Ruby themselves who led our effort to translate the Invitation's rather abstract and utterly alien vision into practical engineering. So they will always have an intimate connection with it, you see. And this particular location is dense with complex electromagnetic fields. Now, the human brain, or the processing that goes on in there, is also a matter of complex electromagnetic fields. And surely those fields could be manipulated by a sufficiently advanced technology: your thoughts could be shaped, your perceptions, your very memories altered, non-invasively but profoundly intimately. So we have brought Ronald and Ruby here in the hope of contact. It is hard to imagine a more complete communication, if it works . . .'
Joshua saw that Sancho had gone to the fence. The marines looked alarmed, but Maggie waved at them to let the troll pass. Sancho pressed his face to the wire and stared at the lollipops.
Joshua too found himself staring in utter dismay. He murmured, âLobsang, tell me. How can people so smart commit something so self-evidently wrong as this?'
âI know what you mean,' Lobsang said grimly. âMaybe it's because the minds of the Next themselves are so new. A hasty rewiring of a system that is after all millions of years old. Things go wrong when you grow too fast. We believe there are asylums at the Grange and elsewhere for the mentally ill â and of course we know of a few crazies who've made it to the human worlds, such as the Napoleons who escaped from Happy Landings by hijacking a Navy twain.'
âAnd look at those two,' Joshua said. âThey hardly look healthy, do they?'
Lobsang said darkly, âBut maybe they have their uses. Let's find out.'
They walked back to the group.
Lobsang asked Roberta now, âSo what success have you had with your communication experiment?'
âNone,' said Maggie without hesitation.
âSome,' Roberta contradicted her.
Maggie put her hands on her hips and glared at her. âThat's news to me.'
Roberta, slim, quiet, looked at them all through her heavy glasses. âYou must see the difficulty. The Thinker's intellect is almost beyond our ability to comprehend. The totality of all human thought could pass through the mind of the Thinker in a few days.
All
of it, since we left the trees. How can we communicate with such a mind? Ruby has said that the Thinker manipulates whole systems of thought â whole sciences, complete philosophies â as we manipulate words in a sentence.'
Lobsang considered this. âAnd yet these two have spoken with the machine, to some extent. Can they say what it wants?'
Roberta looked at the lollipops. â
Join us
. That's still the basic message it's giving us.'
Maggie shook her head. âJoin us? How? Are we supposed to build some kind of wormhole, like in
Contact
?'
âNothing like that. The lollipops say they dream of opening doors.'
âOpening doors.' Suddenly Joshua saw it. He had, after all, lived through Step Day. âStepping. This is all about stepping.'
Lobsang stood back and smiled. âThat's it. We should have seen it from the beginning. And it's just like New Springfield. I was
there
.'
Maggie frowned, as ever wary of rapid developments, of disruption to her carefully controlled order. âLobsang, speak to me.'
âAdmiral, this Invitation is a Long Earth phenomenon. We know that. What's the most fundamental thing about the Long Earth?
Stepping
â the act of mind and body that enables you to travel from one world to the next. But stepping can be more than that. You remember Sally Linsay and her soft places â her leaps across the Long Earth? Then in New Springfield we found the silver beetlesâ'
âWho were able to step between different planets,' Joshua said. âTangled-up Long worlds.'
Dev said excitedly, âAnd perhaps that's why we received the Invitation just now. Because
they
could tell, somehow, that somebody had made that step North, into another world.'
Lobsang and Joshua exchanged a glance. âThe Prime Directive,' said Joshua. âHe's right.
That's
why we received the Invitation just now.'
Lobsang nodded. âWe always wondered where everybody was. They
were
out there, but they were waiting until we were ready â we could only join the party when we discovered how to step in advanced ways. And at New Springfield we achieved the step equivalent of warp drive. Stan Berg was our Zefram Cochrane. And, right on cue, here come the Vulcans.'
Maggie sighed. âYou do realize that nobody here knows what the hell you two are talking about?'
But Roberta said carefully, âAdmiral, based on what I know of our communication with the Thinker â this
feels
right. A partial perception, but a good intuition.' She smiled brilliantly. âI was always one of those who argued for including humans at the very heart of the project. And this shows I was right!'
âI'm happy for you,' Maggie said flatly. âSo what next, Lobsang?'
âAdmiral, we must accept the Invitation. The finer the mind, the more advanced the ability to step. I think this Thinker, this tremendous
mind
, is going to enable us to step out of this world altogether. And we'll go â somewhere else. Just like the beetles.'
Maggie was still frowning. âI suppose that's why I allowed you two to come here, to make these connections. But I don't like it when things move too quickly. Where, then?'
Lobsang peered up at the sky. âWho knows? The Thinker may be able to tell us . . .'
âI'd go,' Lee said immediately. They all stared at her. âI'm just saying.'
Lobsang glanced at Indra Newton, standing some distance away. âAnd we may need another crew member. A specialist. In the end, the silver-beetle interface needed Stan Berg, remember, a super-stepper . . . Ah. All of which you Next foresaw, of course. And which is why you brought Indra here.'
