‘What are you doing?’ he asked.

The four heavily armoured telefactors clambered through a jungle of bracing struts, through masses of hardened crash foam like bracket fungi, and vine-like tangles of optics and cables. Ape-like, they approached an area of the Jack Ketch right behind the nose chamber, which Jack found rather sensitive. He tried to usurp control, found himself unable to. He then tried to summon other mechanisms to deal with the situation, but saw that Aphran had been busy there as well. She had burnt out all of the ship Golem and other robots.

‘We are going to die anyway,’ he said, ‘so why do you attack me?’

‘Because,’ Aphran replied, ‘you seem to have forgotten that you are not this ship. That’s probably a built-in perception to make you fight better.’

With heavy cutting claws, the telefactors swiftly chopped through an armoured bulkhead. In the spherical chamber beyond, caught between two metal protuberances like the business ends of combustion engine valves, was compressed a carapace of black metal that partially wrapped a lozenge of crystal. Turning on their cutting lasers, the telefactors began slicing through the metal columns above and below this object. Jack immediately felt systems going offline, his control slipping away.

‘You are killing me… and yourself,’ he protested.

Like a balloon collapsing, his awareness drew inward, until at length nothing remained to him but the vision of an armoured telefactor reaching for him with one huge crab claw. In that lensed awareness he felt Aphran’s presence.

‘Why?’

‘You’ll see.’

Following the program Aphran had previously input, the telefactor picked up the mind of the attack ship and took it through the internal wreckage to what remained of the erstwhile dropshaft then particle cannon. There it coiled around the mind whilst another program took over the allotted task and, waiting until the tumble of the ship brought the shafts precisely to the correct angle, flipped a switch.

Jack did not become photonic matter—there wasn’t enough power left for that—but he certainly achieved escape velocity. His body, the ship, fell.

Still running, Cormac was within sight of the open when another of the hybrids lunged at him out of the shadows. This one was the same nightmare he had seen through Skellor’s network, and for a moment he could not quite comprehend that it was real. From the waist up she was a woman, but insectile chitinous body with too many legs from the waist down.

‘Back off!’ Cormac yelled, firing into the ground before her. Like all the others, she ignored this and continued to charge him. As her head bent forwards, out of her widening mouth a set of pincers oozed into view. She hissed at him. Cormac shot her twice in the forehead and prepared to shoot away her legs too, but she collapsed, as if unstrung, and he ran on.

His head was aching horribly once again, and he felt thirsty and sick but dared not stop to rest, for that could cost another life. Thus far it had taken him three hours to reach the edge of the Sand Towers—meaning twelve lives—and used up two thin-gun clips. He wondered if to the lives of all those jumping from the city platform he should add those he had left lying in the dust behind him. Though partially human they might appear, they had not behaved like intelligent beings.

There were fires in the city, he noticed, probably due to furnaces left unattended. But most of the structures there being metallic, hopefully would not last very long. Cormac zeroed in on the coordinates he now held in his gridlink. Far to his right he saw a lander lying tilted against a small hill and, recognizing its source, wondered if Cento and Fethan were still alive. His destination was not that lander, though—for it still lay ahead.

As he ran, he reached into his pocket and pressed a couple more glucose tablets from a strip. These he popped into his mouth, washing them down with a sip of water from the tube at his collar. Skellor, he knew, might try to kill him, but maybe that would not happen right away. People were dying in the city right now. That he had no hesitation in giving himself up Cormac supposed the downside of both the responsibility and power of being an agent of Earth Central Security. Yes, he could balance the loss of life at Elysium against what had been the potential loss of life at Masada. In many situations he could be judge, jury and executioner. But when it came to value judgements about human life, he must make no exceptions and also strictly apply the same rules to himself. Under ECS law he would have been well within his rights to say screw the people here, they are not Polity. But his own law would not allow him that.

Cormac ran on for another hour, the fatigue poisons accumulating in his body and pain growing like lead shot in his muscles. Since the Cheyne III AI had turned off his gridlink all those years ago, he had refused all other augmentations, preferring to be no more than the human he had been born. But even with that limitation, he was still, due to genetic manipulation, the best human possible, possessing the reserves and strengths of an Olympian. Now, with his gridlink functioning for no apparent reason and Jain fibres lacing his brain, such distinctions had become laughable.

His feet thumping down on a spongy fungal layer covering the dunes, Cormac laboured up one final slope. Another hour had now passed during which, doubtless, other victims had jumped to their deaths. Breasting the slope, he gazed down on another ancient landing craft, raised up on its hydraulic feet with a ramp down and lights on inside it. Behind the craft, the sun was poised like a poison fruit on the horizon.

‘You can stop the killing now,’ he announced. He did not shout, did not think it would be necessary, for surely Skellor would hear him. His thin-gun at his side, Cormac headed down towards the craft.

Skellor himself stepped into view, in the airlock, then walked down onto the dust.

‘You can stop the killing now,’ Cormac repeated.

‘No.’ Skellor grinned.

Cormac had expected nothing else, but that did not excuse him from making the attempt. There was only one other way, then—four shots slammed into the bio-physicist’s chest. Burning deep, one blew pieces out of his back. Cormac could not decide if it was a grimace or a grin that twisted the man’s features before he stepped aside and… disappeared. Keeping his finger on the trigger, Cormac continued firing in the direction he felt sure his enemy had gone. The shots punched smoking lines down the side of the landing craft.

Transferring his attention to the ground the agent noticed footprints, so fired again, glimpsed a flickering snarling image. When a red light displayed on his gun, he ejected the clip while simultaneously pulling another from his belt—his reloading so fast there was no pause in his fusillade. The footsteps suddenly disappeared.

Cormac calculated, turned and aimed in a completely new direction, tracked across, and hit something. A second later the gun was snatched, smoking, from his hand, and he himself was hurled to the ground.

Skellor reappeared, the gun in his hand. On his body various holes were slowly closing.

‘It’s an automatic program walking them off the edge—so killing me won’t stop it,’ he sneered.

Cormac rolled to his feet, his hands held out at either side. ‘You have me now, so what do you get by killing them?’

‘To torment you, of course.’

Cormac considered hurling himself at the biophysicist’s throat, but recognized the futility of the act. Any thought of running was futile too.

‘They will all die—like clockwork,’ Skellor added, unnecessarily.

Calculation: Skellor could only torment him while he was conscious. Cormac hurled himself forwards, groping for Skellor’s throat. The hot barrel of his own thin-gun smacked against his temple, knocking him to the ground. He rolled upright, but Skellor was invisible once more. Something hit his head again, splitting his scalp so that a flap of skin lifted on the pulse of blood. Knuckles smashed into his nose—more blood, more pain—and more blows followed. When he felt he had taken enough, Cormac shut down his perceptile programs and allowed his consciousness to leave him.
