World of the Drone Part 5

But now that her usefulness to him was over, he didn't know just what to do about her. The sensible thing would be, of course, simply to kill her. Somehow he felt that he couldn't do that. It was one thing to kill in the impersonal fury of machine combat, a different matter when the victim was helpless within your reach.... And he remembered that she _had_ helped him escape.

He could command her to return to her people, to the tender mercies of the Spider Mother--who would know by now of Qanya's part in Dworn's disappearance. d.a.m.n it, that would probably be worse than killing her in cold blood! He was wasting time. Angry at himself for his unbeetlelike softness, Dworn postponed deciding what to do with her till he should have inspected his machine and made sure it was in shape to travel.

"Come along," he told the girl gruffly. "Outside."

Once more she obeyed unprotesting. The two clambered out of the belly of the standing spider--Qanya staring before her with sleepwalking fixity, Dworn nervously scanning sky and horizon for hostile machines. The sunlit waste was terrifyingly immense bright, and empty. With a physical ache of yearning he longed for the cramped security of his own machine's cabin.

He brushed past the girl and ran toward the upside-down beetle--he could easily right it with a spare emergency cartridge, and then he would be on his way in a normal world again--

He stopped short with one hand on the beetle's dull-black steel flank.

The world seemed to rock around him.

The girl watched him without expression as his face went slack with horror, as he completed his arrested movement and dived into the cabin to confirm the dreadful discovery that first touch had disclosed to him.

When Dworn climbed out he was white and shaking. He took a few steps away from the beetle and sank weakly down on the sunwarmed sand.

"What's the matter?" asked Qanya.

He turned and looked dully at her. He had completely forgotten that she was there.

He said listlessly, "I'm _dead_."

"Of course you're dead." Her brows puckered faintly as she gazed at him.

"Naturally, I drained your fuel tanks last night--"

Dworn surged to his feet and took one step toward her, fists knotted, blown by a gust of fury. She stared levelly back at him, unflinching--and he halted, shoulders drooping. "Ah, what's the use?"

He should have foreseen this--not that it would have done any good if he had. The beetle's fuel supply had been drunk up by the spider now towering over them; and the beetle's engine, even idling at minimum consumption, had used up what little remained in the system, and had stopped. And it was as if Dworn's own lifeblood had been drained and his own heart had stopped beating.

Qanya was still watching him blankly. She said, "Can't you start it again?"

Dworn was jolted by the realization that she genuinely didn't understand that he _was_ dead--that there was no way of restarting an engine once stopped. Until now he had supposed that all races were the same in that respect; but evidently spiders were different. In fact, now he remembered that, when they had entered the spider-vehicle, the girl had pushed a b.u.t.ton that apparently started the engine. Spiders, then, died and came to life again every day--a startling notion.

But the beetles--Among the thoughts that tumbled disjointedly through Dworn's head in this awful moment was a clear vision of the night, five years ago, when his machine-existence had begun: when, in the horde's encampment by the sea a thousand miles from here, the beetle's last seam had been welded, and its engine set going with the appropriate ritual of birth.... The sixteen-year-old boy's heart had beaten high and proudly, in tune with the heart of steel and fire that had begun to throb at that moment. And the life expectancy of the two was measured with the same measure, the life of flesh and that of metal indissolubly entwined....

He mumbled dazedly, "I'm dead, do you hear? Dead!"

There was a sudden howling in the sky. Flashing overhead, as the two stood momentarily petrified, went a shrieking flight of half a dozen winged shapes--stubby vanes slanting back from vicious noses, they hurtled low over the desert and vanished swiftly into the distance, dust-devils dancing across the ground in the whirling wind of their pa.s.sage.

Dworn stared after them, and his eyes narrowed. A new and desperate resolve had begun shaping itself in his mind.

Of the things he had meant to do in life, it was no use thinking any more of rejoining his people. He was dead to them, for sure--not even a beetle any more, but only what was left of one, a ghost.... But a holy duty, stronger than death, remained to him; his father was still unrevenged.

What he could do against a foe so powerful as those who had just pa.s.sed over, he had no idea--but perhaps a ghost could accomplish what a living man might well deem impossible.

He motioned Qanya peremptorily toward the waiting spider-machine. "Come on. We're taking your machine, and we're going to find _them_!"

For a moment she seemed to hesitate ... then she obeyed. If her face was paler than usual, Dworn failed to notice it.

The spider-vehicle lurched and swayed, even its marvelous system of shock-absorbers protesting as it climbed steeply, straddling upward from rock to rock.

Dworn clutched at handholds inside the pitching cabin and tried to combat the sympathetic lurching of his stomach. Qanya huddled tensely over the controls, slim hands flashing nimbly to and fro as with incredible deftness she guided the laboring machine.

Dworn risked a glimpse from the turret-windows, then shut his eyes with a rush of giddiness. They were climbing now up the steepest part of the great slide, where the mountainside had collapsed in a chaos of splintered rock and tumbled crags that would have been utterly impa.s.sible for any wheeled vehicle. Below them, the sloping valley floor they had left appeared from this height entirely flat and sickeningly far away. And still the cliff-heads frowning above them seemed terribly remote.

"How ... far?" gasped Dworn.

"It can't be very far now to the top," said Qanya, without glancing up from her absorbed concentration. Both their lives were in her hands; a slip, a misstep, and they might fall hundreds of feet among the jagged rocks to their death.

For seconds at a time, the walking machine poised motionless, one or more of its clawed limbs groping for footholds. As it clambered painfully upward, it was hopelessly exposed to attack if it should be sighted from the air.

_Dworn_, the beetle told himself savagely, _you are not only a ghost, you are an insane ghost_. _Only a madman would have undertaken such a journey._

The cabin heeled wildly as the machine grappled a ledge and, its engine panting at full throttle, levered itself upward a few more feet.

He had commanded the spider girl to find the route by which her people had descended. But twice already they had missed the way and had arrived at dead ends beyond which it was impossible to climb higher; twice they had been forced to descend and search for an easier path. It had been scarcely noon when they started; now the sun was already sinking low.

Dworn could not even be sure that he would find his sworn enemies beyond the Barrier. But the duty of vengeance was all he had left to live for, since what was to have been his triumphal return had ended in bereavement and catastrophe.

_And a dead man_, thought Dworn bleakly, _needs something to live for, even more than other people do_.

The world came level again, for the moment. The machine sidled precariously along a narrow ledge girdling an unscalable wall of rock, as Qanya sought a spot to resume the ascent. Dworn winced at the thought that the way might be blocked again. But, no--fifty yards further on, the wall was breached, and toppled boulders formed a perilous but not impossible stairway.

Just as Qanya grasped the levers which would set the spider scrambling upward once more, there was a sound--one grown hatefully familiar to Dworn since the night before, the feverish buzzing of a number of light high-speed engines. He opened his mouth to hiss a warning, but Qanya too had heard. Instantly she guided the spider-machine as close as possible to the cliff, where the hollowed rock afforded some shelter, and twirled a k.n.o.b that made it sink down, legs folding compactly.

They waited scarcely breathing. A couple of times before they had huddled like this, while flights of the winged enemies whistled over ...

but the wingless ones? It seemed impossible that they should be up here, where surely nothing that ran on wheels could travel....

The head of a column of the aluminum crawlers came into view, whirring along the ledge with a confident air of knowing where they were going.

One by one, the little machines rolled past within a few feet of the crouching spider, hastening on with an uncanny pre-occupation.

Dworn saw that, like those he had seen earlier, they were of diverse kinds; and several of them, fitted with claws and racks for transporting booty, were heavily laden now with metal plates and girders carved from some larger machine, a roll of caterpillar tread, a slightly bent axle.... The last pygmy in line, whose afterbody was a bloated tank, gurgled as it jolted by, and trailed an aroma of looted fuel.

A few yards beyond the staring watchers, each of the little plunderers pivoted sharply in its turn and without even slackening speed vanished straight into the cliff-face. Dworn and Qanya looked incredulously at one another.

"A tunnel!" Dworn grunted in realization.

That explained one mystery, at least--how, if the winged and wingless strangers' home base was somewhere above the cliffs, the wheeled machines contrived to forage at the foot of the Barrier. They must have one or more inclined tunnels, bored through solid rock for a distance that staggered Dworn's imagination. Emerging at this level, they had found or constructed a pa.s.sable road the rest of the way to the valley floor.... Now he noticed that the ledge to which the spider had so laboriously climbed showed signs of being an often-used trail, and the cliffs it skirted exhibited in places the raw marks of recent blasting.

"Remember this spot," he told Qanya. "If we should return this same way--there's evidently an easier path down."

She said nothing. Dworn wondered wrily if, in her drug beclouded mind, she was aware of how unlikely it was that either of them would be returning from beyond the Barrier.
