"Forget it!" snapped DeChance, turning off her force shield. "We have to get out of here while we can."

Lindholm nodded quickly. He put away his gun, turned off his shield, and made a stirrup with his hands.

DeChance put her foot into it, and the marine boosted her up into the hole in the ceiling. The esper found a handhold, and pulled herself up and out onto the street above. Corbie turned off his force shield and followed her out the same way. The alien surged forward, crushing the stones on the floor under its immense bulk. Lindholm calmly pulled a concussion grenade from his bandolier, primed it, and tossed it into the gaping mouth, which snapped shut reflexively. Lindholm pushed some of the larger pieces of rubble together, climbed up onto them and pulled himself up into the hole. Corbie and DeChance hauled him out onto the street.

He rolled quickly away from the opening, and seconds later there was a m.u.f.fled roar from below as the grenade went off. Blood and gore fountained up out of the hole, and cracks spread across the street.

"Nice one, Sven," said Corbie.

The three of them got to their feet and looked around them. The sun had sunk almost out of sight, and the green sky was darkening towards night. The city had become little more than shapes and shadows, with the occasional lighted window. The copper tower loomed above its surrounding buildings, less than half a mile away. Corbie shivered, and checked that his heating elements were set at maximum.

"Still no sign of the rest of the Squad," said Lindholm. "I hope they're having an easier time than us."

Corbie sniffed. "They probably had an attack of common sense and got the h.e.l.l out of here."

"We'd better keep moving," said DeChance. "There are aliens nearby. More than I can count. They know we're here, and they're closing in on us."

She ran down the street without stopping to see if the marines were following. They looked quickly at each other, shared a sour smile, and hurried after her. From close at hand came the screams and cries of pursuing aliens, as the first of the unsteady creatures spilled onto the street after the fleeing Squad.

And in the copper tower, the great device waited patiently for them to come to it.

CHAPTER SEVEN.

The Sleep of Reason Monsters roamed the city streets. Some flew in the air, while others burrowed in the earth. Creatures formed by madness and obsession made their way to the copper tower, summoned by a voice they could not refuse. They no longer remembered why, but the echo of that voice moved within them, whatever shape they wore, and always would. The sun had fallen, and darkness lay across the city.

Strange lights burned in the silent buildings as more and more creatures awoke from their centuries-long sleep and went out into the streets. Hideous shapes crept and crawled between structures they no longer recognised, in a city they had long since forgotten. They had lived for centuries, and might live for centuries more, but they did not know it. The awful thing they had done to themselves had trapped them forever in the here and now; in a single endless moment of existence. They had forgotten what they were, and what they had hoped to be. Only the great device remembered. And it was insane.

Hunter and Krystel ran down a twisting street, between stone monoliths with blazing windows and looming edifices of steel and crystal. The darkness hung around them like a listening stranger, and from every intersection they pa.s.sed came more shapes and monstrosities to join the boiling pack that pursued them. Hunter was fighting for air, and his back and leg muscles screamed for rest, but he didn't dare slow his pace. The aliens were close on their heels, and drawing closer. The darkness hid most of the shapes that followed them, for which Hunter was grateful.

A shining figure stepped out of a stone monolith and reached for Krystel with phosph.o.r.escent hands.

She cut sideways with her sword without slowing her pace, and severed the nearest hand. It fell sparking and sputtering into the street, and the creature howled wordlessly. Hunter thought briefly about using his disrupter, but decided against it as the alien fell back, clutching at its ruined arm with its remaining hand.

The disrupter's energy crystals were running low, and he only used the gun now when there was no other choice.

He ran on after Krystel, hurdling the twitching hand in the street without slowing. His breath burned in his lungs, and sweat ran down his heaving sides. He glared at the Investigator. She'd been running and fighting just as much as him, and she wasn't even breathing hard. She was even smiling slightly as she shook the last creature's shimmering blood from her sword. Hunter shook his head wearily and blinked away the sweat that ran down into his eyes. It seemed some of the things he'd heard about Investigators and their training weren't exaggerations after all.

A winged shape dropped out of the sky towards Hunter, its wings flapping loosely as its yard-long beak stabbed down at his face. He raised his force shield above his head, and the beak shattered on the energy field. The alien screamed and flapped away, blood dripping from its ruined face. A barbed tentacle shot up out of the pursuing pack and pulled the alien down. The pack fell on it and tore it apart.

Hunter and Krystel ran on.

The copper tower stood tall and imposing against the skyline; an enigmatic silhouette against the alien night. Hunter scowled at it. He'd chosen the tower as a rendezvous point because it could be clearly seen from anywhere in the city, but he was beginning to wish he'd chosen somewhere closer. He'd lost track of how long he'd been running, but the tower seemed as far away as ever. Something moved in a nearby alleyway, and the Investigator turned her gun on it.

"No, Krystel!" Hunter knocked her arm aside at the last moment. "They're friends."

Krystel lowered her gun as Megan DeChance and the two marines plunged out of the alleyway to run alongside them. They all managed a quick nod of greeting to each other, but none of them had the breath for conversation. They ran on, with Krystel and the esper leading the way. Hunter looked at the two marines, and winced. Their uniforms were torn and stained with blood. Fatigue had put bruises under their eyes, and made their movements heavy and plodding. They didn't look like they could run much further. Hunter smiled sourly. He didn't suppose he looked much better.

But he and the rest of the Squad would run as far as they had to; because the only alternative was to lie down and die. Hunter looked at the esper's back and frowned. He'd only caught a brief glimpse of DeChance's face, but she'd looked to be in an even worse state than the marines. If there was a weak link in the Squad, she was it. And valuable as she was, Hunter hoped she wouldn't fall. None of them had the strength left to carry her. The esper began to speak, and Hunter made himself pay attention.

In fits and starts, with many pauses for breath, DeChance explained the history of the city, and what had happened there, and for the first time Hunter and Krystel understood the true nature of the aliens, and the significance of the copper tower. Hunter had a hundred questions he wanted to ask, but he didn't have the breath for even one. The tower suddenly loomed up before him at the end of the street, and he fixed his attention on that. The Squad pounded down the street, and skidded to a halt at the base of the tower.

The two marines turned to face the pursuing aliens, and fired their disrupters. Several aliens fell screaming to the ground as the energy beams cut through them, and the rest of the pack fell on them. Hunter turned to find DeChance and the Investigator silently studying the copper tower.

"Well, don't just stand there. Get the b.l.o.o.d.y door open! The aliens will be here any minute!"

"We appear to have a problem, Captain," said the Investigator. "No door. No windows, either."

Hunter held up his field lantern and studied the tower closely for the first time. The great copper shaft stretched up into the night sky, featureless and immaculate save for the ma.s.sive copper spikes that radiated from its peak. It looked to be thirty to forty feet in diameter, and maybe four hundred feet high.

There was no trace of any opening in the gleaming metal, nor any sign there ever had been one. Hunter stepped forward and ran his hand across the metal. It felt preternaturally slick, almost frictionless.

"All right," he said quietly. "Stand back and watch out for flying metal." He fired his disrupter at the metal wall at point-blank range. The energy beam punched a tiny hole in the metal, and that was all.

"Great," said Corbie. "Now what?"

Hunter thought quickly. "Explosives. How many grenades have we got between us?"

He had one, Krystel had one, DeChance had two. The marines had used all theirs.

"That isn't going to be enough, Captain," said the Investigator. "The disrupter should have opened up the tower wall like a tin can. It didn't. A wall that strong isn't going to be bothered by concussion grenades.

The force of the explosion would be too generalized."

"So what do you suggest?" snapped Corbie. "Kick the b.l.o.o.d.y thing? Or maybe we should knock politely and hope someone will let us in?"

"Keep the noise down, marine," said Hunter. "There is a way. We can use one of our proximity mines.

That's powerful enough, and focused enough, to do the job. All we have to do is place one against the base of the tower wall, set the timer, and get the h.e.l.l out of the way."

"That might just do it," said Lindholm approvingly. "Be a h.e.l.l of a bang, anyway."

Hunter glanced quickly at the aliens. They'd stopped some distance away from the tower, and were watching silently. Presumably the great device didn't want them any closer, for its own security. Krystel produced a proximity mine from her backpack, put it in place, and set the timer. The Squad then moved quickly round to the far side of the tower. The explosion sounded strangely m.u.f.fled, as though the tower had absorbed some of the blast, but when they went back to look they found a gaping hole in the tower wall, some five to six feet in diameter.

"We'd better tread carefully, once we get inside," said Krystel. "The blast may have damaged the device."

"It did," said DeChance. "But it's only superficial damage. I can feel the strength of the device. It burns in my mind like a beacon."

Hunter looked at her, and then at the two marines. They stirred uncomfortably.

"She has some kind of telepathic link with the device, Captain," said Lindholm slowly. "She thinks it's alive."

"And insane," said DeChance. "Quite definitely insane. I don't think it knows we're here yet, but it will the moment we enter the tower. I can't shield myself against that kind of power."

"This is all very interesting," said Hunter carefully, "but can you tell us anything more practical about the device?"

"Yes," said DeChance. "The explosion damaged one important part of the device. Try your comm unit, Captain. I think you'll find it's working again now."

Hunter gaped at her for a moment, and then tried his comm implant. It immediately patched him in with the pinnace computers, and for the first time that day Hunter felt complete again. Being cut off from the computers was like being cut off from his own memory. He gave the pinnace an update on what the Squad had discovered, and added a series of general orders for the computers to follow, if by some chance the Squad didn't make it back from the city. He checked the pinnace's power reserves and nodded slowly to himself. There was enough there to do what was needed. He dropped out of contact, and turned back to the Squad. They were talking animatedly as they discovered their comm units were working again too. Hunter coughed loudly to get their attention.

"All right, people. We're back in the game with a new deck. I've instructed the pinnace computers to warm up all the ship's systems. As soon as the ship's ready, I'll have the computers fly her here on remote control, and we'll get the h.e.l.l out of this city."

"Sounds good to me," said Corbie. "The sooner we're out of here, the better."

"We can't leave," said DeChance.

"Try and stop me," said Corbie.

"The esper's right, Captain," said Krystel quickly. "For better or worse, this planet is our home now. We have to make our life here. And as long as this city and its creatures exist, we can never be safe. We can't communicate with them, and we can't live alongside them. They are insane, and as we have seen, quite deadly. It's us or them, Captain, and this may be the best chance we'll ever get to destroy them.

They're dependent on this tower; if we destroy the great device, the aliens should die with it. If we leave the city now, we may never get another shot at the tower."

"You can't be sure of that," said Hunter. "And there's no guarantee that destroying the tower will destroy the aliens."

"Nothing's sure in this madhouse," said Krystel, "but it's our best bet."

"Yes," said Hunter finally. "I think it is." He patched into the pinnace computers again, fixed the flight plan, and set the engines in motion. "The ship's on its way, people. If we're going to destroy this tower, we'd better get a move on. You are sure the device is somewhere in this tower, DeChance?"

"The machine isn't in the tower, Captain," said the esper. "The machineis the tower. All of it."

She stepped through the jagged hole into the tower, holding her lantern up before her. Hunter and the others exchanged glances, and then followed her in. Outside in the night, the aliens tore savagely at each other, no longer interested in the Squad. The tower had them now.

Inside the copper tower there were huge shapes of metal and gla.s.s and crystal, fitted together in ways that made no sense to human eyes. Their dimensions seemed to vary according to which angle they were viewed from. There were parts that moved, and others that weren't always there, and there was a continuous low murmur of sound, as though the device were whispering secrets to itself. Hunter looked up into the tower, and saw the device stretching away above him; huge, cyclopean, and inhumanly intricate. Whoever, or whatever, had conceived the great device had a mind that worked on a different scale from humanity.

"This is it," said DeChance quietly. "This is the machine that freed the aliens from the tyranny of a fixed shape. This is where they made their own d.a.m.nation."

"And it's still working, after who knows how many centuries," said Krystel.

"It's been asleep a long time," said DeChance. "It's awake now. And it knows we're here."

Hunter rubbed at his forehead. A vicious headache had started the moment he entered the tower. He felt hot and sweaty, and his fingers tingled uncomfortably.

"Are you all right, Captain?" asked Krystel quietly.

"I'm fine," said Hunter quickly. "Just the long day catching up with me."

"No," said DeChance. "It's the device. It's starting to work on us, now. It'll affect any living thing that stays within its influence too long. And the closer you are, the greater the effect is."

"Hey, wait a minute," said Corbie. "You mean we're going to turn into things like the aliens? Right. That's it. I'm off."

"Go outside on your own and the aliens will tear you to pieces," said DeChance. "But they won't come in here after us. The device wouldn't permit it. We're safe enough from the tower's influence for now. It takes time . . ." She held up her left hand and looked at it. The fingers had fused together into a single fleshy paw. "Of course, some of us are more susceptible than others."

Hunter looked at her closely, shocked, taking in the changes in her face since he'd last seen her. She'd definitely lost weight, and her bone structure was prominent almost to the point of emaciation. She stood awkwardly, and her stance was . . . different somehow. Changed. The marines hadn't noticed, because the changes had been slow and subtle, but they were clear enough now that Hunter was looking for them.

"How much longer can you stay here?" he asked softly. "Before the changes become . . . dangerous."

"I don't know. My esp makes me vulnerable, but you'll need that to help you find the device's weak spots. If it has any. The great device has survived for centuries without outside care or maintenance. It's bound to have self-defence mechanisms. I'm not even sure it can be destroyed with our feeble weapons.

But we have to try." She looked around her. "There's a ramp nearby that leads up into the heart of the device. I think our best bet would be to plant our remaining explosives in the middle of the tower, or as close as we can get, and then make our escape on the pinnace before they blow." She looked at Hunter.

"We'd better get moving, Captain. We don't have much time."

Hunter nodded soberly. "All right then, esper; lead the way. Investigator, you follow right behind her.

Shoot anything that even looks threatening. The marines and I will bring up the rear. Shields on, guns and swords at the ready. Let's go, people."

DeChance moved confidently through the warren of enigmatic shapes, and stepped onto a simple ramp that led up into the heart of the machine. The rest of the Squad followed. Strange forms came and went around them as they trudged up the ramp, and Hunter began to feel like an insect that had become trapped in the workings of a machine it couldn't hope to understand. There was a kind of sense, of meaning, to the great device, but he could only recognise it without appreciating it. There were lights and sounds, and sudden rises and falls in temperature, and none of it made any sense.

The ramp wound between layers of shimmering crystal, and static sparked on the air. Hunter's headache grew worse, and his stomach felt increasingly uneasy. No doubt some of it was due to tension, but he couldn't help wondering how much of it might be caused by the device, and how long it would be before his body began changing, like DeChance's.

Metallic tentacles suddenly swung down from above, like writhing snakes. They seemed endless in the unsteady light, and they were tipped with reaching clawed hands. The Squad got their force shields up just in time, and the razor-sharp claws recoiled from the glowing energy fields. More tentacles came reaching out of nowhere, striking and retreating with inhuman speed. Hunter tried his sword against one of them, and the hilt jarred painfully in his hand as the steel blade sprang away without leaving a mark.

The marines fired their guns, but the tentacles moved too quickly even for their experienced reflexes. The Investigator had used the edge of her shield to sever one tentacle, but the remaining tentacles avoided the shield's edges. It seemed they learned quickly. Blood flew on the air as the claws struck home, despite the force shields.

DeChance suddenly went down on one knee and hid behind her shield, eyes closed. Hunter moved quickly in beside her to protect her, but as far as he could see she hadn't been hurt. Her gaunt face was twisted with concentration, and in that moment she looked subtly inhuman to Hunter, as though an imperfect duplicate had taken the esper's place. DeChance's eyes snapped open, and Hunter's hackles rose on his neck. Her eyes were pools of bloodred, with long, split pupils.

"Three o'clock, Captain! Fire at three o'clock and you'll stop the defence mechanism!"

Hunter hesitated a moment, and then fired blindly where the esper indicated. There was an explosion somewhere up above, and the ramp shuddered under his feet. The tentacles disappeared back into the maze of machinery. The Squad slowly lowered their shields and looked around them. Hunter looked at DeChance, and did his best to meet her disquieting eyes.

"Very good, DeChance. Any more surprises we ought to know about?"

"Not yet, Captain, but we've got to move faster. The tower's influence is growing. I can feel it building.

Soon you'll all start to change. Like me." Her voice had become harsh and strained, almost a growl. One arm was now clearly longer than the other. She smiled at Hunter, and her teeth had points. "It's not far now, Captain. I've located a weak spot where we can set our explosives."

She walked on up the ramp, and her body moved to an inhuman rhythm. Hunter's mouth was dry and sweat ran down his face. He wondered what the esper was becoming, and whether he was looking at his own future. Could he live, like that? Would he want to? He swallowed hard, and forced himself to concentrate on the business at hand. All that mattered now was setting the explosives and getting out of the city before they went off. He'd worry about anything else later. If there was a later.

They came to a place where thousands of wires seethed and writhed like a nest of worms. Electrical discharges skittered on the air. A crystal turned slowly in the midst of the wires, like a watchful eye.

"This is it," said DeChance. "I think it's some kind of relay. Blow this, and the whole tower will come down. If we're lucky."

"Lucky," said Corbie disgustedly. "I haven't felt lucky since we landed on this b.l.o.o.d.y planet."

The Squad set about emptying their backpacks, and between them they a.s.sembled a pile of proximity mines and grenades. The pile looked pitifully small, set against the vastness of the tower. Krystel arranged the explosives so as to do the most damage, and then checked the timers. She looked at Hunter, her face set and grim.

"Captain, we may have a problem here."

"Oh great," said Corbie. "Another problem. Just what we needed."

"Keep the noise down, Corbie," said Hunter. "What's the problem, Investigator?"

"The proximity mines, Captain. The timers have a maximum setting of thirty minutes. There's no way we can get out of here and reach a safe distance in thirty minutes."
