“In Earth atmosphere the glue oxidizes in about three minutes,” Carol replied. “I could maybe fix that once we see them coming, but only then.”
Var considered that. Once Ricard and the rest made a move, assuming they used a crawler, they could get themselves here within ten minutes. Only ten minutes for Carol to spray glue on every bulkhead door handle within reach, then get safely back to the reactor room.
“Too much of a risk.” She shook her head. “You’d be very exposed and there’s a chance they could either kill you or cut you off from us before you got back to the reactor room.” She called up a schematic of Hex Three on the computer screen. “Including Ricard himself, there’ll be seven of them,” she decided. “He won’t know for certain where we are inside the hex, so he’ll keep one or two men outside to snipe at us if we try to escape. They’ll blow each remaining window in turn, searching each room after its window has been blown. Almost certainly they’ll throw in grenades before entering, and probably spray the interiors with gunfire too.”
“But they can’t come through the garage windows, because there aren’t any,” observed Carol.
“Precisely,” Var glanced at her. “Which is why I wanted Lopomac here to set up a booby trap.”
“But even if we do manage to kill some of them in the airlock, the rest will still enter through the bulkhead doors. They’ll know we’re either in the garage or in one of the closed-off inner sections…as we will be.”
Var nodded. “Certainly. They’ll blow bulkhead doors leading into the garage, and then secure it just as they have all the other outer rooms of the hex, before they move on to open each of the inner sections and search them.”
“We’ll be trapped in the reactor room, so what’s our angle?” asked Lopomac.
“The roof,” said Var.
Argus Station
It was now evident that the warming process was well under way. When he reached his hand to rest it against the door, Saul could feel the vibration of machinery through his fingers, and through the window saw plumes of vapour jetting here and there from the engine itself. Probing the computer network in the immediate vicinity, he checked to see how close the engine was to firing temperature, then inspected the diagnostic data. Despite a couple of minor faults, the engine was now ready and, with just a thought, he could start it running. However, even though the process of shutting it down was a lengthy one, Smith could initiate that with a thought too.
Saul moved back out into the open, then skirted the wall, studying in his mind a schematic of all the hardware nearby as he progressed. Finally reaching a certain point, he looked up, and noted a mass of optic cables that emerged from the wall above, then ran along a beam continuing out of sight somewhere behind him. He leapt up towards it, caught hold and pulled himself over, coming down astride the cables just at the point where they exited the wall.
Here the sheer mass of cables was further distended by a great number of connector plugs all gathered together. Slowly and methodically he checked the codes etched into the side of each plug, till on the eighth one found the optic connection he sought. This plug, however, could not simply be pulled apart, being tightly secured by a ring of screws. Saul pulled it away from the others, drew his pistol and fired a shot. The cable was whipped out of his hand, the shattered plug parting, while the frayed optic cables provided a display of green and yellow laser light. Retrieving the plug, he could now pull it apart. That ensured that the hardwire connection was removed and, when the Traveller VI engine fired up, the EM interference produced would make it impossible to issue radio instructions able to shut it down. Saul propelled himself back to the floor. Time now to stack the dice even further.
Saul waited at the entrance to the tunnel leading through the wall insulation, gazing back at the Arboretum cylinder. How much force could the structural beams here withstand? They were much more widely spaced than would be required for a building on Earth, but would soon be subjected to levels of stress halfway approaching the same. Since he had set the engine to fire up at its maximum, the initial thrust would be in the region of half a gravity. He paused for a moment to make some complex calculations and discovered that, though the massive shaft spindles of the Arboretum and the arcoplexes would take a huge amount of the resulting strain, there would be substantial damage caused to the intervening areas. That was unavoidable, however. As he finished making calculations which confirmed that any internal buildings still under construction—like the Political Office and the cell block—might tear loose from their mountings, he finally sensed that his five construction robots were approaching, and turned to face them.
With animal grace they headed down the face of the asteroid, coming from Tech Central, and he began firming up his connection with them and further preparing them for action. Soon they were gathered around him, his pack of eager steel wolves. Instructing them to follow, he turned and entered the short tunnel that took him to the edge of the engine enclosure. Bracing his feet against the ground, he hauled up a simple mechanical latch and pushed open the door. The engine loomed above him, and when he gazed up past it he could see the stars. Now he propelled himself upwards, catching hold of occasional protrusions from the inner ceramic-tiled wall to keep himself close to it, and avoid flying out into open vacuum. In another moment he ascended past the open throats of the fusion chambers, and then understood why the insulated wall had been built. Remembering the specs of the Traveller VI engine, he knew that the fusion torch would lance out way beyond the station, its length nearly two kilometres, and producing sufficient heat to melt anything nearby. He glanced down to see his robots following him up the wall, their limbs never out of contact with its sheer expanse of tiles.
Finally, near the station rim, he caught hold of the protruding end of a beam end and halted his climb, then pulled himself over to stand upright on the rim itself, which curved away from him like a long hill on some massive highway. Looking up he could see the smelting plant, whose dock lay just beyond the point where the Arboretum cylinder terminated. The plant resembled an ugly spined iron fish now that its mirrors were furled. That was something else he would have to deal with because, once the station started moving, the smelting plants would swing round on their cables and come crashing down with catastrophic force. However, returning those things to their docks would certainly alert Smith to his presence.
His five robots escorting him, Saul picked up his pace, knowing he must cover nearly six kilometres to reach his destination. Entering one of the half-constructed levels enabled him to speed up since, with a ceiling above him, he could propel himself forward confidently without any danger of floating out into space. Emerging into the open again, he paused a moment in wonder, because the arc of Earth itself was now visible. Moving on, he quickly rounded the structures located directly above the Arboretum, and then came in sight of the massive pit of the smelting-plant dock, which he circumvented too. The pillars of the space-plane dock loomed into sight ahead, as if he was trudging the highway towards the tower blocks of a city centre. However, the illusion was dispelled by a single space plane moored to the nearest pillar, like a dragonfly larva clinging to a reed.
One of the Argus Station’s massive steering thrusters jutted up between him and his destination. It was a thing the size and shape of a railway carriage, but tilted at forty-five degrees on a turntable fifty metres wide. When he had first studied this station from Earth, these things had resided at the ends of twenty-metre-tall structures constructed of reinforced girders, which projected outwards from the station rim. Now, by contrast, this particular thruster lay only a few metres from the surface, the rim itself having been extended out nearly far enough to encompass it. As he gazed at this object, Saul detected movement and swung his attention back to Earth, where the swarm of space planes was rising into view.
He quickly headed into the hard shadow of the thruster, and almost at once found the maintenance hatch he was looking for. Though he needed primarily to get to the docks, approaching
them across the rim itself would have been foolish, since the troops entrenched there would be on the lookout for a flanking move by Langstrom’s men, and would be sure to spot him. Besides, even though most of the laser satellites nearby were disabled, Smith still controlled a few usable laser satellites within range, and might spot him too.
The maintenance hatch was not designed to be opened by human hands, but a simple instruction called one of the robots over, which inserted an outsize Allen key to disengage the locking mechanism. A slight puff of vapour blew out as the hatch hinged open, but that probably wasn’t station atmosphere but the result of fuel spillage. Summoning his five robots to follow him, Saul dropped inside and found himself in a narrow space alongside the huge stepper motor used for driving the turntable mechanism, powering a great cog above him which engaged with a massive toothed ring.
Skirting around this motor he found a tunnel leading to the distant space dock. Built to accommodate robots, it was also lined with fuel pipes from the silos there. As the last robot closed the hatch behind it, the lights went out, but he had two of the robots light up their fault-inspection lasers, and damp coherence, to illuminate his surroundings in lurid red. Ten minutes of propelling himself along the tunnel brought him to a point where many of the pipes diverged upwards to connect with the various silos located along the base of the docks above. However, other pipes ran ten metres further in, before curving upwards into the nearest docking pillar, there to connect to the pumps used to fuel space planes engaged in orbital duties.
Climbing up alongside these pipes brought him to an inspection point for human technicians. Here secondary pipes branched off to connect to the fuel pumps positioned immediately behind the hydraulic systems that extended concertinaed fuel hoses out to any plane currently docked. Saul opened the adjacent manual airlock and entered, summoning just one of his robots in with him. Once the lock had cycled, he opened the inner door and stepped into a maintenance area containing a spare pump, a variety of pipe and hydraulic fittings, along with some of the heavy-duty machinery required to install them. Here seemed as good a place as any to set things in motion as he meanwhile guided the remaining robots through the same airlock.
Saul delved deep into the station network, making no attempt now to conceal his presence. Seeking first to crack their control codes, he probed Smith’s remaining readerguns and robots. Smith reacted immediately, the shadowy presence of his mind thrashing like a hooked bloodworm before he started shoring up his defences. This was just what was needed for, whilst keeping the pressure on him, Saul slipped past Smith and into long-dormant portions of the station network, to gain access to a process only rarely called for up here.
On occasion a smelting plant required major maintenance that could not be conducted out there in space, and therefore it was winched back into its dock, furling its solar panels and burrowing into the station skin like the head of a tubeworm. He now set this process in motion for both plants, and watched as the folded panels withdrew into their soot-stained bodies. Under his feet he felt the station’s heavy thrumming as giant cable drums began to revolve, winding in kilometres of cable thicker in diameter than his thigh. It took a moment for Smith to realize what was going on, but instead of trying to stop this process he focused his attention on the cell block, and after a moment he spoke.
“Saul,” was all he said, his voice ghosting across the network.
“You should have killed me,” Saul replied.
“You had not ceased to be of use to me.” Now, probing began into the informational architecture that Saul was fortifying. “I am now puzzled as to why you feel the need to retract the smelting plants.”
“I’m ensuring Messina has no place to land but on the space-plane docks themselves.”
“Ah, so you recognize the dangers in Messina’s assumption of ultimate power, and are therefore prepared to ally yourself with me to ensure his defeat?”
Saul paused in the midst of checking the readings on the air sampler strapped about his wrist, but it took him just a second to realize that Smith had finally gone over the edge. No sane man could ever expect to make an ally out of someone he had subjected to inducement. Saul shook his head in disbelief and returned his attention to the sampler. The air was pure CO2, thin, and rapidly getting thinner, so he could not remove his VC helmet. This was not surprising because, as he understood it, airlocks like the one just behind him had been designed for some future era when the entire docks themselves could be pressurized—but now they remained airless.
“I fully understand that at present Messina is a greater danger to me than you are,” Saul replied carefully. “I also understand that, should he try to get his troops into Argus like Malden did, you probably still control enough long-range satellite lasers to burn them off the station’s surface.”
From the cam systems under Smith’s control, an image feed opened directly across into Tech Central itself. Saul quickly noticed that all the available seats were occupied, while Smith himself stood in front of the three major screens. Off to one side he could see Hannah bound to a chair, and clearly Smith must be routeing his voice through the intercom, because now she was looking up with interest.
“And what other approaches might you suggest?” Smith asked. “I would be interested to discover your unique perspective on the matter.”
A cracked and desperate mind would be easier to manipulate, Saul surmised, but it was also likely to spin out of control and head off in unpredictable directions.
“I still control some resources,” he replied, “but you’ll understand why I’m not keen to reveal what they are, or how I intend to use them. For the moment, however, I will cease any attempt to take readerguns or robots away from you.” Saul halted his mental assault on these devices. “I would rather they were used against Messina than we render them useless by fighting over control of them.” He paused, wondering how best to conclude this. “I’ll do what I can against Messina—but then I’m coming after you, Smith.”
Stepping away from the screens, Smith moved over to stand next to Hannah, pressing a hand down onto her shoulder. “Once I have fully re-established my position here, I certainly look forward to that encounter.”
Perfect. Smith had not looked beyond Saul’s explanation about the smelting plants, but his threat regarding Hannah was clear. Saul studied the scene further and assessed her position. When the steering thrusters turned the station round, the effect there would be negligible, but once the Traveller engine fired up, over half a gravity would surge through Tech Central horizontally. Her chances of surviving that, strapped in a chair as she was, he rated at about 70 per cent. He could do nothing about the uncertain 30 per cent, for if her head slammed into the consoles just to her right, she’d probably end up with a broken neck. Nevertheless, in her present position, he doubted she would resent him taking that chance.
“Later, then,” concluded Saul. “The first of Messina’s planes will be docking here within twenty minutes, and I’m sure you have plenty to do.”
The image feed cut off, though, unlike before, it now remained unblocked so Saul could seek it out whenever he wished. Instead he checked out other areas of the station, noting how Langstrom’s troops were scattered in squads of four throughout the lower section of the inner core, but far enough above the asteroid so that it was not right up against their backs and therefore blocking a retreat. Most of these four-man units controlled hefty machine guns and missile-launchers, though Langstrom himself had taken the controls of a weapon Saul now identified as Smith’s one EM tankbuster. Between them and the outer rim, robots were constantly on the move, laying antipersonnel mines activated by wires strung nearly invisibly between the structural beams.
Arcoplex One had also been secured. Inside it, Smith controlled a good number of functioning readerguns, and a team of soldiers was busy loading them with ceramic ammunition. But that wasn’t a route Messina’s troops were likely to be taking—why enter an obvious killing ground? No, they would come straig
ht down on Langstrom’s troops through intervening girderwork of the station, possibly using shields and deploying more spiderguns. They would certainly face heavy losses, but Saul doubted that would much concern Messina, as in the end sheer numbers would prevail. A greater worry to Messina would be the serious losses Saul was intending to inflict.
Saul crossed to the large sliding door separating the maintenance store from the dock’s interior, his robots following sneakily as if they sensed his need of increased caution. He probed for some access to the nearby cameras, but found that, though the system remained live, little image data was available from within this particular dock. Messina’s first arriving troops had obviously destroyed the cameras, just as he knew they had disabled the readerguns here too. However, one camera continued to function, and on switching it up to its 270-degrees setting revealed enough of the dock to show that no guards had been posted actually inside.
Unshouldering one of his carbines, Saul moved over to the door control. He pressed it once and watched the door judder as it slid aside, aware how it would have made a considerable racket if the dock had been pressurized. The moment it opened wide enough, he pulled himself through and, with another of those slightly disorientating changes of perspective, brought his feet down on the dock floor on the other side. In a squatting position he checked his surroundings. To his left stood a cargo train, while from the floor directly ahead rose the personnel access tube leading to the space plane, and just beyond it the cargo-access doors stood wide open. He turned to study the far wall, noting the tunnel cutting through it for the train, and numerous open corridors leading into the station rim.
He rose and headed rapidly over to the access tube, detailing one of his robots to the cargo hold, one to follow him, and dispersing the remaining three about the dock. Within seconds he was gazing through the sensors of the first robot, to confirm that the cargo hold now contained only a few crates of munitions. Descending through the tube to the plane’s airlock, he paused to study its controls, and found nothing more difficult than an electronic lock. He stepped inside the airlock and waited till the red lights turned to green before he removed his helmet, then opened the inner door on to a muttering of voices. Before he stepped further, he summoned the robot into the airlock behind him, instructing it to wait there—an unpleasant surprise for anyone who tried entering the plane after him.
