The World That Couldn't Be

n one leap, he was at Sipar's side. He reached down and grasped the native by an arm, jerked it erect, held it on its feet. Sipar's eyes snapped open, blinking in the firelight.

The rumble had grown to a roar and there were thumping noises, as of heavy boulders bouncing, and beneath the roar the silky, ominous rustle of sliding soil and rock.

Sipar jerked its arm free of Duncan's grip and plunged into the darkness. Duncan whirled and followed.

They ran, stumbling in the dark, and behind them the roar of the sliding, bouncing rock became a throaty roll of thunder that filled the night from brim to brim. As he ran, Duncan could feel, in dread anticipation, the gusty breath of hurtling debris blowing on his neck, the crushing impact of a boulder smashing into him, the engulfing flood of tumbling talus snatching at his legs.

A puff of billowing dust came out and caught them and they ran choking as well as stumbling. Off to the left of them, a mighty chunk of rock chugged along the ground in jerky, almost reluctant fashion.

Then the thunder stopped and all one could hear was the small slitherings of the lesser debris as it trickled down the slope.

Duncan stopped running and slowly turned around. The campfire was gone, buried, no doubt, beneath tons of overlay, and the stars had paled because of the great cloud of dust which still billowed up into the sky.

He heard Sipar moving near him and reached out a hand, searching for the tracker, not knowing exactly where it was. He found the native, grasped it by the shoulder and pulled it up beside him.

Sipar was shivering.

'It's all right,' said Duncan.

And it was all right, he reassured himself. He still had the rifle. The extra drum of ammunition and the knife were on his belt, the bag of rockahominy in his pocket. The canteens were all they had lost—the canteens and the fire.

'We'll have to hole up somewhere for the night,' Duncan said. 'There are screamers on the loose.'

e didn't like what he was thinking, nor the sharp edge of fear that was beginning to crowd in upon him. He tried to shrug it off, but it still stayed with him, just out of reach.

Sipar plucked at his elbow.

'Thorn thicket, mister. Over there. We could crawl inside. We would be safe from screamers.'

It was torture, but they made it.

'Screamers and you are taboo,' said Duncan, suddenly remembering. 'How come you are afraid of them?'

'Afraid for you, mister, mostly. Afraid for myself just a little. Screamers could forget. They might not recognize me until too late. Safer here.'

'I agree with you,' said Duncan.

The screamers came and padded all about the thicket. The beasts sniffed and clawed at the thorns to reach them, but finally went away.

When morning came, Duncan and Sipar climbed the scarp, clambering over the boulders and the tons of soil and rock that covered their camping place. Following the gash cut by the slide, they clambered up the slope and finally reached the point of the slide's beginning.

There they found the depression in which the poised slab of rock had rested and where the supporting soil had been dug away so that it could be started, with a push, down the slope above the campfire.

And all about were the deeply sunken pug marks of the Cytha!

ow it was more than just a hunt. It was knife against the throat, kill or be killed. Now there was no stopping, when before there might have been. It was no longer sport and there was no mercy.

'And that's the way I like it,' Duncan told himself.

He rubbed his hand along the rifle barrel and saw the metallic glints shine in the noonday sun. One more shot, he prayed. Just give me one more shot at it. This time there will be no slip-up. This time there will be more than three sodden hunks of flesh and fur lying in the grass to mock me.

He squinted his eyes against the heat shimmer rising from the river, watching Sipar hunkered beside the water's edge.

The native rose to its feet and trotted back to him.

'It crossed,' said Sipar. 'It walked out as far as it could go and it must have swum.'

'Are you sure? It might have waded out to make us think it crossed, then doubled back again.'

He stared at the purple-green of the trees across the river. Inside that forest, it would be hellish going.

'We can look,' said Sipar.

'Good. You go downstream. I'll go up.'

An hour later, they were back. They had found no tracks. There seemed little doubt the Cytha had really crossed the river.

They stood side by side, looking at the forest.

'Mister, we have come far. You are brave to hunt the Cytha. You have no fear of death.'

'The fear of death,' Duncan said, 'is entirely infantile. And it's beside the point as well. I do not intend to die.'

They waded out into the stream. The bottom shelved gradually and they had to swim no more than a hundred yards or so.

They reached the forest bank and threw themselves flat to rest.

Duncan looked back the way that they had come. To the east, the escarpment was a dark-blue smudge against the pale-blue burnished sky. And two days back of that lay the farm and the vua field, but they seemed much farther off than that. They were lost in time and distance; they belonged to another existence and another world.

All his life, it seemed to him, had faded and become inconsequential and forgotten, as if this moment in his life were the only one that counted; as if all the minutes and the hours, all the breaths and heartbeats, wake and sleep, had pointed toward this certain hour upon this certain stream, with the rifle molded to his hand and the cool, calculated bloodlust of a killer riding in his brain.

ipar finally got up and began to range along the stream. Duncan sat up and watched.

Scared to death, he thought, and yet it stayed with me. At the campfire that first night, it had said it would stick to the death and apparently it had meant exactly what it said. It's hard, he thought, to figure out these jokers, hard to know what kind of mental operation, what seethings of emotion, what brand of ethics and what variety of belief and faith go to make them and their way of life.

It would have been so easy for Sipar to have missed the trail and swear it could not find it. Even from the start, it could have refused to go. Yet, fearing, it had gone. Reluctant, it had trailed. Without any need for faithfulness and loyalty, it had been loyal and faithful. But loyal to what, Duncan wondered, to him, the outlander and intruder? Loyal to itself? Or perhaps, although that seemed impossible, faithful to the Cytha?

What does Sipar think of me, he asked himself, and maybe more to the point, what do I think of Sipar? Is there a common meeting ground? Or are we, despite our humanoid forms, condemned forever to be alien and apart?
