The Seeds of Time (23 page)

The months of service kept on piling up; going a very great deal faster now. During the later stretch, when one had acquired confidence in his ability to get through without cracking up, there was a comfortable feeling about sitting quietly out there with the knowledge of the money gradually piling up at home.

A new find opened up on Callisto, bringing a slight increase in deliveries to the satellite. Otherwise, the routine continued unchanged. The infrequent ships called in, loaded up, and went again. And then, surprisingly soon, it was possible for Duncan to say to himself: ‘Next ship but one, and I'll be through!' Even more surprisingly soon there came the day when he stood on the metal apron outside the dome, watching a ship lifting herself off on her under-jets and dwindling upwards into the black sky, and was able to tell himself: ‘That's the last time I'll see that! When the next ship lifts off this dump, I'll be aboard her, and then – boy, oh boy … !'

He stood watching her, one bright spark among the others, until the turn of the satellite carried her below his horizon. Then he turned back to the airlock – and found the door shut …

Once he had decided that there was going to be no repercussion from the Alan Whint affair he had let his habit of wedging it open with a piece of rock lapse. Whenever he emerged to do a job he left it ajar, and it stayed that way until he came back. There was no wind, or anything else on the satellite to move it. He laid hold of the latch-lever irritably, and pushed. It did not move.

Duncan swore at it for sticking. He walked to the edge of the metal apron, and then jetted himself a little round the side of the dome so that he could see in at the window. Lellie was sitting in a chair with the spring-cover fixed across it, apparently lost in thought. The inner door of the airlock was standing open, so of course the outer could not be moved. As well as the safety-locking device, there was all the dome's air pressure to hold it shut.

Forgetful
for the moment, Duncan rapped on the thick glass of the double window to attract her attention; she could not have heard a sound through there, it must have been the movement that caught her eye and caused her to look up. She turned her head, and gazed at him, without moving. Duncan stared back at her. Her hair was still waved, but the eyebrows, the colour, all the other touches that he had insisted upon to make her look as much like an Earth woman as possible, were gone. Her eyes looked back at him, set hard as stones in that fixed expression of mild astonishment.

Sudden comprehension struck Duncan like a physical shock. For some seconds everything seemed to stop.

He tried to pretend to both of them that he had not understood. He made gestures to her to close the inner door of the airlock. She went on staring back at him, without moving. Then he noticed the book she was holding in her hand, and recognized it. It was not one of the books which the Company had supplied for the station's library. It was a book of verse, bound in blue. It had once belonged to Alan Whint …

Panic suddenly jumped out at Duncan. He looked down at the row of small dials across his chest, and then sighed with relief. She had not tampered with his air-supply: there was pressure there enough for thirty hours or so. The sweat that had started out on his brow grew cooler as he regained control of himself. A touch on the jet sent him floating back to the metal apron where he could anchor his magnetic boots, and think it over.

What a bitch! Letting him think all this time that she had forgotten all about it. Nursing it up for him. Letting him work out his time while she planned. Waiting until he was on the very last stretch before she tried her game on. Some minutes passed before his mixed anger and panic settled down and allowed him to think.

Thirty hours! Time to do quite a lot. And even if he did not succeed in getting back into the dome in twenty or so of them, there would still be the last, desperate resort of shooting himself off to Callisto in one of the cylinder-crates.

Even
if Lellie were to spill over later about the Whint business, what of it? He was sure enough that she did not know
how
it had been done. It would only be the word of a Mart against his own. Very likely they'd put her down as space-crazed.

… All the same, some of the mud might stick; it would be better to settle with her here and now – besides, the cylinder idea was risky; only to be considered in the last extremity. There were other ways to be tried first.

Duncan reflected a few minutes longer, then he jetted himself over to the smaller dome. In there, he threw out the switches on the lines which brought power down from the main batteries charged by the sun-motor. He sat down to wait for a bit. The insulated dome would take some time to lose all its heat, but not very long for a drop in the temperature to become perceptible, and visible on the thermometers, once the heat was off. The small capacity, low voltage batteries that were in the place wouldn't be much good to her, even if she did think of lining them up.

He waited an hour, while the faraway sun set, and the arc of Callisto began to show over the horizon. Then he went back to the dome's window to observe results. He arrived just in time to see Lellie fastening herself into her space-suit by the light of a couple of emergency lamps.

He swore. A simple freezing out process wasn't going to work, then. Not only would the heated suit protect her, but her air supply would last longer than his – and there were plenty of spare bottles in there even if the free air in the dome should freeze solid.

He waited until she had put on the helmet, and then switched on the radio in his own. He saw her pause at the sound of his voice, but she did not reply. Presently she deliberately switched off her receiver. He did not; he kept his open to be ready for the moment when she should come to her senses.

Duncan returned to the apron, and reconsidered. It had been his intention to force his way into the dome without damaging it, if
he could. But if she wasn't to be frozen out, that looked difficult. She had the advantage of him in air – and though it was true that in her space-suit she could neither eat nor drink, the same, unfortunately, was true for him. The only way seemed to be to tackle the dome itself.

Reluctantly, he went back to the small dome again, and connected up the electrical cutter. Its cable looped behind him as he jetted across to the main dome once more. Beside the curving metal wall, he paused to think out the job – and the consequences. Once he was through the outer shell there would be a space; then the insulating material – that was okay, it would melt away like butter, and without oxygen it could not catch fire. The more awkward part was going to come with the inner metal skin. It would be wisest to start with a few small cuts to let the air-pressure down – and stand clear of it: if it were all to come out with a whoosh he would stand a good chance in his weightless state of being blown a considerable distance by it. And what would she do? Well, she'd very likely try covering up the holes as he made them – a bit awkward if she had the sense to use asbestos packing: it'd have to be the whoosh then … Both shells could be welded up again before he re-aerated the place from cylinders … The small loss of insulating material wouldn't matter … Okay, better get down to it, then …

He made his connexions, and contrived to anchor himself enough to give some purchase. He brought the cutter up, and pressed the trigger-switch. He pressed again, and then swore, remembering that he had shut off the power.

He pulled himself back along the cable, and pushed the switches in again. Light from the dome's windows suddenly illuminated the rocks. He wondered if the restoration of power would let Lellie know what he was doing. What if it did? She'd know soon enough, anyway.

He settled himself down beside the dome once more. This time the cutter worked. It took only a few minutes to slice out a rough, two-foot circle. He pulled the piece out of the way, and
inspected the opening. Then, as he levelled the cutter again, there came a click in his receiver: Lellie's voice spoke in his ear:

‘Better not try to break in. I'm ready for that.'

He hesitated, checking himself with his finger on the switch, wondering what counter-move she could have thought up. The threat in her voice made him uneasy. He decided to go round to the window, and see what her game was, if she had one.

She was standing by the table, still dressed in her space-suit, fiddling with some apparatus she had set up there. For a moment or two he did not grasp the purpose of it.

There was a plastic food-bag, half-inflated, and attached in some way to the table top. She was adjusting a metal plate over it to a small clearance. There was a wire, scotch-taped to the upper side of the bag. Duncan's eye ran back along the wire to a battery, a coil, and on to a detonator attached to a bundle of half a dozen blasting-sticks …

He was uncomfortably enlightened. It was very simple – ought to be perfectly effective. If the air-pressure in the room should fall, the bag would expand: the wire would make contact with the plate: up would go the dome …

Lellie finished her adjustment, and connnected the second wire to the battery. She turned to look at him through the window. It was infuriatingly difficult to believe that behind that silly surprise frozen on her face she could be properly aware what she was doing.

Duncan tried to speak to her, but she had switched off, and made no attempt to switch on again. She simply stood looking steadily back at him as he blustered and raged. After some minutes she moved across to a chair, fastened the spring-cover across herself, and sat waiting.

‘All right then,' Duncan shouted inside his helmet. ‘But you'll go up with it, damn you!' Which was, of course, nonsense since he had no intention whatever of destroying either the dome or himself.

He had never learnt to tell what went on behind that silly
face – she might be coldly determined, or she might not. If it had been a matter of a switch which she must press to destroy the place he might have risked her nerve failing her. But this way, it would be he who operated the switch, just as soon as he should make a hole to let the air out.

Once more he retreated to anchor himself on the apron. There must be
some
way round, some way of getting into the dome without letting the pressure down … He thought hard for some minutes, but if there was such a way, he could not find it – besides, there was no guarantee that she'd not set the explosive off herself if she got scared …

No – there was no way that he could think of. It would have to be the cylinder-crate to Callisto.

He looked up at Callisto, hanging huge in the sky now, with Jupiter smaller, but brighter, beyond. It wasn't so much the flight, it was the landing there. Perhaps if he were to cram it with all the padding he could find … Later on, he could get the Callisto fellows to ferry him back, and they'd find some way to get into the dome, and Lellie would be a mighty sorry girl –
mighty
sorry …

Across the levelling there were three cylinders lined up, charged and ready for use. He didn't mind admitting he was scared of that landing: but, scared or not, if she wouldn't even turn on her radio to listen to him, that would be his only chance. And delay would do nothing for him but narrow the margin of his air-supply.

He made up his mind, and stepped off the metal apron. A touch on the jets sent him floating across the levelling towards the cylinders. Practice made it an easy thing for him to manoeuvre the nearest one on to the ramp. Another glance at Callisto's inclination helped to reassure him; at least he would reach it all right. If their beacon there was not switched on to bring him in, he ought to be able to call them on the communication radio in his suit when he got closer.

There was not a lot of padding in the cylinder. He fetched more from the others, and packed the stuff in. It was while he
paused to figure out a way of triggering the thing off with himself inside, that he realized he was beginning to feel cold. As he turned the knob up a notch, he glanced down at the meter on his chest – in an instant he knew … She had known that he would fit fresh air-bottles and test them; so it had been the battery, or more likely, the circuit, she had tampered with. The voltage was down to a point where the needle barely kicked. The suit must have been losing heat for some time already.

He knew that he would not be able to last long – perhaps not more than a few minutes. After its first stab, the fear abruptly left him, giving way to an impotent fury. She'd tricked him out of his last chance, but, by God, he could make sure she didn't get away with it. He'd be going, but just one small hole in the dome, and he'd not be going alone …

The cold was creeping into him, it seemed to come lapping at him icily through the suit. He pressed the jet control, and sent himself scudding back towards the dome. The cold was gnawing in at him. His feet and fingers were going first. Only by an immense effort was he able to operate the jet which stopped him by the side of the dome. But it needed one more effort, for he hung there, a yard or so above the ground. The cutter lay where he had left it, a few feet beyond his reach. He struggled desperately to press the control that would let him down to it, but his fingers would no longer move. He wept and gasped at the attempt to make them work, and with the anguish of the cold creeping up his arms. Of a sudden, there was an agonizing, searing pain in his chest. It made him cry out. He gasped – and the unheated air rushed into his lungs, and froze them …

In the dome's living-room Lellie stood waiting. She had seen the space-suited figure come sweeping across the levelling at an abnormal speed. She understood what it meant. Her explosive device was already disconnected; now she stood alert, with a thick rubber mat in her hand, ready to clap it over any hole that might appear. She waited one minute, two minutes … When
five minutes had passed she went to the window. By putting her face close to the pane and looking sideways she was able to see the whole of one space-suited leg and part of another. They hung there horizontally, a few feet off the ground. She watched them for several minutes. Their gradual downward drift was barely perceptible.
