Chapter 10

His determination to resist must have gotten across to the leader, for he did not urge obedience to his orders. Instead he waved the Terran to join his own party. And since Raf had no reason not to, he did. Leaving the dead, both alien and enemy, where they had fallen, the warriors took another way out of the underground maze, a way which brought them out into a street running to the river.

Here the party spread out, paying close attention to the pavement, as if they were engaged in tracking something. Raf saw impressed in one patch of earth a print dried by the sun, left by one of the reptiles. And there were smaller tracks he could not identify. All were inspected carefully, but none of them appeared to be what his companions sought.

They trotted up and down along the river bank, and from what he had already observed concerning the aliens, Raf thought that the leader, at least, was showing exasperation and irritation. They expected to find something--it was not there--but it had to be! And they were fast reaching the point where they wanted to produce it themselves to justify the time spent in hunting for it.

Ruthlessly they rayed to death any creature their dragnet drove into the open, leaving feebly kicking bodies of the furry, long-legged beasts Raf had first seen after the landing of the spacer. He could not understand the reason for such wholesale extermination, since certainly the rabbitlike rodents were harmless.

In the end they gave up their quest and circled back to come out near the field where the flitter and the globe rested. When the Terran flyer came into sight, Raf left the party and hurried toward it. Soriki waved a welcoming hand.

"'Bout time one of you showed up. What are they doing--toting half the city here to load into that thing?"

Raf looked along the other's pointing finger. A party of aliens towing a loaded dolly were headed for the gaping hatch of the globe, while a second party and an empty conveyance passed them on the way back to the storehouse.

"They are emptying a warehouse, or trying to."

"Well, they act as if Old Time himself was heating their tails with a rocket flare. What's the big hurry?"

"Somebody's been here." Swiftly Raf outlined what he had seen in the city, and ended by describing the hunt in which he had taken an unwilling part. "I'm hungry," he ended and went to burrow for a ration pack.

"So," mused Soriki as Raf chewed the stuff which never had the flavor of fresh provisions, "somebody's been trying to beat the painted lads to it. The furry people?"

"It was a spear shaft they found broken with the dead lizard thing," Raf commented. "And some of those on the island were armed with spears--"

"Must be good fighters if, armed with spears, they brought down a reptile as big as you say. It was big, wasn't it?"

Raf stared at the city, a square of half-eaten concentrate in his fingers. Yes, that was a puzzler. The dead monster would be more than _he_ would care to tackle without a blaster. And yet it was dead, with a smashed spear for evidence as to the manner of killing.

All those others dead in the arena, too. How large a party had invaded the city? Where were they now?

"I'd like to know," he was speaking more to himself than to the com-tech, "how they _did_ do it. No other bodies--"

"Those could have been taken away by their friends," Soriki suggested. "But if they're still hanging about, I hope they won't believe that we're bigger and better editions of the painted lads. I don't want a spear through me!"

Raf, remembering the maze of lanes and streets--bordered by buildings which could provide hundreds of lurking places for attackers--which he had threaded with the confidence of ignorance earlier that day, began to realize why the aliens had been so nervous. Had a sniper with a blast rifle been stationed at a vantage point somewhere on the roofs today none of them would ever have returned to this field. And even a few spacemen with good cover and accurate throwing aim could have cut down their number a quarter or a third. He was developing a strong distaste for those structures. And he had no intention of returning to the city again.

He lounged about with Soriki for the rest of the afternoon, watching the ceaseless activity of the aliens. It was plain that they were intent upon packing into the cargo hold of their ship everything they could wrest from the storage house. As if they must make this trip count double. Was that because they had discovered that their treasure house was no longer inviolate?

In the late afternoon Hobart and Lablet came back with one of the work teams. Lablet was still excited, full of what he had seen, deduced, or guessed during the day. But the captain was very quiet and sober, and he unstrapped the wrist camera as soon as he reached the flitter, turning it over to Soriki.

"Run that through the ditto," he ordered. "I want two records as soon as we can get them!"

The com-tech's eyebrows slid up, "Think you might lose one, sir?"

"I don't know. Anyway, we'll play it safe with double records." He accepted the ration pack Raf had brought out for him. But he did not unwrap it at once; instead he stared at the globe, digging the toe of his space boot into the soil as if he were grinding something to powder.

"They're operating under full jets," he commented. "As if they were about due to be jumped--"

"They told us that this was territory now held by their enemies," Lablet reminded him.

"And who are these mysterious enemies?" the captain wanted to know. "Those animals back on that island?"

Raf wanted to say yes, but Lablet broke in with a question concerning what had happened to him, and the pilot outlined his adventures of the day, not forgetting to give emphasis to the incident in the celled room when the newly rescued alien had turned upon him.

"Naturally they are suspicious," Lablet countered, "but for a people who lack space flight, I find them unusually open-minded and ready to accept us, strange as we must seem to them."

"Ditto done, Captain." Soriki stepped out of the flitter, the wrist camera dangling from his fingers.

"Good." But Hobart did not buckle the strap about his arm once more, neither did he pay any attention to Lablet. Instead, apparently coming to some decision, he swung around to face Raf.

"You went out with that scouting party today. Think you could join them again, if you see them moving for another foray?"

"I could try."

"Sure," Soriki chuckled, "they couldn't do any more than pop him back at us. What do you think about them, sir? Are they fixing to blast us?"

But the captain refused to be drawn. "I'd just like to have a record of any more trips they make." He handed the camera to Raf. "Put that on and don't forget to trigger it if you do go. I don't believe they'll go out tonight. They aren't too fond of being out in the open in darkness. We saw that last night. But keep an eye on them in the morning--"

"Yes, sir." Raf buckled on the wristband. He wished that Hobart would explain just what he was to look for, but the captain appeared to think that he had made everything perfectly plain. And he walked off with Lablet, heading to the globe, as if there was nothing more to be said.

Soriki stretched. "I'd say we'd better take it watch and watch," he said slowly. "The captain may think that they won't go off in the dark, but we don't know everything about them. Suppose we just keep an eye on them, and then you'll be ready to tail--"

Raf laughed. "Tailing would be it. I don't think I'll have a second invitation and if I get lost--"

But Soriki shook his head. "That you won't. At least if you do--I'm going to make a homer out of you. Just tune in your helmet buzzer."

It needed a com-tech to think of a thing like that! A small adjustment to the earphones built into his helmet, and Soriki, operating the flitter com, could give him a guide as efficient as the spacer's radar! He need not fear being lost in the streets should he lose touch with those he was spying upon.

"You're on course!" He pulled off his helmet and then glanced up to find Soriki smiling at him.

"Oh, we're not such a bad collection of space bums. Maybe you'll find that out someday, boy. They breezed you into this flight right out of training, didn't they?"

"Just about," Raf admitted cautiously, on guard as ever against revealing too much of himself. After all, his experience was part of his record, which was open to anyone on board the spacer. Yes, he was not a veteran; they must all know that.

"Someday you'll lose a little of that suspicion," the com-tech continued, "and find out it isn't such a bad old world after all. Here, let's see if you're on the beam." He took the helmet out of Raf's hands and, drawing a small case of delicate instruments from his belt pouch, unscrewed the ear plates of the com device and made some adjustments. "Now that will keep you on the buzzer without bursting your eardrums. Try it."

Raf fastened on the helmet and started away from the flitter. The buzzer which he had expected to roar in his ears was only a faint drone, and above it he could easily hear other sounds. Yet it was there, and he tested it by a series of loops away from the flyer. Each time as he came on the true beam he was rewarded by a deepening of the muted note. Yes, he could be a homer with that, and at the same time be alert to any other noise in his vicinity.

"That's it!" He paid credit where it was due. But he was unable to break his long habit of silence. Something within him still kept him wary of the com-tech's open friendliness.

None of the aliens approached the flitter as the shadows began to draw in. The procession of moving teams stopped, and most of the burden-bearing warriors withdrew to the globe and stayed there. Soriki pointed this out.

"They're none too sure, themselves. Look as if they are closing up for the night."

Indeed it did. The painted men had hauled up their ramp, the hatch in the globe closed with a definite snap. Seeing that, the com-tech laughed.

"We have a double reason for a strict watch. Suppose whatever they've been looking for jumps _us_? They're not worrying over that it now appears."

So they took watch and watch, three hours on and three hours in rest. When it came Raf's turn he did not remain sitting in the flitter, listening to the com-tech's heavy breathing, but walked a circular beat which took him into the darkness of the night in a path about the flyer. Overhead the stars were sharp and clear, glittering gem points. But in the dead city no light showed, and he was sure that no aliens camped there tonight.

He was sleeping when Soriki's grasp on his shoulder brought him to that instant alertness he had learned on field maneuvers half the Galaxy away.

"Business," the com-tech's voice was not above a whisper as he leaned over the pilot. "I think they are on the move."

The light was the pale gray of pre-dawn. Raf pulled himself up with caution to look at the globe. The com-tech was right. A dark opening showed on the alien ship; they had released their hatch. He fastened his tunic, buckled on his equipment belt and helmet, strapped his boots.

"Here they come!" Soriki reported. "One--two--five--no, six of them. And they're heading for the city. No dollies with them, but they're all armed."

Together the Terrans watched that patrol of alien warriors, their attitude suggesting that they hoped to pass unseen, hurry toward the city. Then Raf slipped out of the flyer. His dark clothing in this light should render him largely invisible.

Soriki waved encouragingly and the pilot answered with a quick salute before he sped after his quarry.

A HOUND IS LOOSED

Dalgard's feet touched gravel; he waded cautiously to the bank, where a bridge across the river made a concealing shadow on the water. None of the mermen had accompanied him this far. Sssuri, as soon as his human comrade had started for the storage city, had turned south to warn and rally the tribes. And the merpeople of the islands had instituted a loose chain of communication, which led from a clump of water reeds some two miles back to the seashore, and so out to the islands. Better than any of the now legendary coms of his Terran forefathers were these minds of the spies in hiding, who could pick up the racing thoughts beamed to them and pass them on to their fellows.

Although there were no signs of life about the city, Dalgard moved with the same care that he would have used in penetrating a snake-devil's lair. In the first hour of dawn he had contacted a hopper. The small beast had been frightened almost out of coherent thought, and Dalgard had had to spend some time in allaying that terror to get a fractional idea of what might be going on in this countryside.

Death--the hopper's terror had come close to insanity. Killers had come out of the sky, and they were burning--burning--All living things were fleeing before them. And in that moment Dalgard had been forced to give up his plan for an unseen spy ring, which would depend upon the assistance of the animals. His information must come via his own eyes and ears.

So he kept on, posting the last of the mermen in his mental relay well away from the city, but swimming upstream himself. Now that he was here, he could see no traces of the invaders. Since they could not have landed their sky ships in the thickly built-up section about the river, it must follow that their camp lay on the outskirts of the metropolis.

He pulled himself out of the water. Bow and arrows had been left behind with the last merman; he had only his sword-knife for protection. But he was not there to fight, only to watch and wait. Pressing the excess moisture out of his scant clothing, he crept along the shore. If the strangers were using the streets, it might be well to get above them. Speculatively he eyed the buildings about him as he entered the city.

Dalgard continued to keep at street level for two blocks, darting from doorway to shadowed doorway, alert not only to any sound but to any flicker of thought. He was reasonably sure, however, that the aliens would be watching and seeking only for the merpeople. Though they were not telepathic as their former slaves, Those Others were able to sense the near presence of a merman, so that the sea people dared not communicate while within danger range of the aliens without betraying themselves. It was the fact that he was of a different species, therefore possibly immune to such detection, which had brought Dalgard into the city.

He studied the buildings ahead. Among them was a cone-shaped structure which might have been the base of a tower that had had all stories above the third summarily amputated. It was ornamented with a series of bands in high relief, bands bearing the color script of the aliens. This was the nearest answer to his problem. However the scout did not move toward it until after a long moment of both visual and mental inspection of his surroundings. But that inspection did not reach some twelve streets away where another crouched to watch. Dalgard ran lightly to the tower at the same moment that Raf shifted his weight from one foot to the other behind a parapet as he spied upon the knot of aliens gathered below him in the street....

The pilot had followed them since that early morning hour when Soriki had awakened him. Not that the chase had led him far in distance. Most of the time he had spent in waiting just as he was doing now. At first he had believed that they were searching for something, for they had ventured into several buildings, each time to emerge conferring, only to hunt out another and invade it. Since they always returned with empty hands, he could not believe that they were out for further loot. Also they moved with more confidence than they had shown the day before. That confidence led Raf to climb above them so that he could watch them with less chance of being seen in return.

It had been almost noon when they had at last come into this section. If two of them had not remained idling on the street as the long moments crept by, he would have believed that they had given him the slip, that he was now a cat watching a deserted mouse hole. But at the moment they were coming back, carrying something.

Raf leaned as far over the parapet as he dared, trying to catch a better look at the flat, boxlike object two of them had deposited on the pavement. Whatever it was either needed some adjustment or they were attempting to open it with poor success, for they had been busied about it for what seemed an unusually long time. The pilot licked dry lips and wondered what would happen if he swung down there and just walked in for a look-see. That idea was hardening into resolution when suddenly the group below drew quickly apart, leaving the box sitting alone as they formed a circle about it.

There was a puff of white vapor, a protesting squawk, and the thing began to rise in jerks as if some giant in the sky was pulling at it spasmodically. Raf jumped back. Before he could return to his vantage point, he saw it rise above the edge of the parapet, reach a level five or six feet above his head, hovering there. It no longer climbed; instead it began to swing back and forth, describing in each swing a wider stretch of space.

Back and forth--watching it closely made him almost dizzy. What was its purpose? Was it a detection device, to locate him? Raf's hand went to his stun gun. What effect its rays might have on the box he had no way of knowing, but at that moment he was sorely tempted to try the beam out, with the oscillating machine as his target.

The motion of the floating black thing became less violent, its swoop smoother as if some long-idle motor was now working more as its builders had intended it to perform. The swing made wide circles, graceful glides as the thing explored the air currents.

Searching--it was plainly searching for something. Just as plainly it could not be hunting for him, for his presence on that roof would have been uncovered at once. But the machine was--it must be--out of sight of the warriors in the street. How could they keep in touch with it if it located what they sought? Unless it had some built-in signaling device.

Determined to keep it in sight, Raf risked a jump from the parapet of the building where he had taken cover to another roof beyond, running lightly across that as the hound bobbed and twisted, away from its masters, out across the city in pursuit of some mysterious quarry....

* * * * *

The climb which had looked so easy from the street proved to be more difficult when Dalgard actually made it. His hours of swimming in the river, the night of broken rest, had drained his strength more than he had known. He was panting as he flattened himself against the wall, his feet on one of the protruding bands of colored carving, content to rest before reaching for another hold. To all appearances the city about him was empty of life and, except for the certainty of the merpeople that the alien ship and its strange companion had landed here, he would have believed that he was on a fruitless quest.

Grimly, his lower lip caught between his teeth, the scout began to climb once more, the sun hot on his body, drawing sweat to dampen his forehead and his hands. He did not pause again but kept on until he stood on the top of the shortened tower. The roof here was not flat but sloped inward to a cuplike depression, where he could see the outline of a round opening, perhaps a door of sorts. But at that moment he was too winded to do more than rest.

There was a drowsiness in that air. He was tempted to curl up where he sat and turn his rest into the sleep his body craved. It was in that second or so of time when he was beginning to relax, to forget the tenseness which had gripped him since his return to this ill-omened place, that he touched--

Dalgard stiffened as if one of his own poisoned arrows had pricked his skin. Rapport with the merpeople, with the hoppers and the runners, was easy, familiar. But this was no such touch. It was like contacting something which was icy cold, inimical from birth, something which he could never meet on a plain of understanding. He snapped off mind questing at that instant and huddled where he was, staring up into the blank turquoise of the sky, waiting--for what he did not know. Unless it was for that other mind to follow and ferret out his hiding place, to turn him inside out and wring from him everything he ever knew or hoped to learn.

As time passed in long breaths, and he was not so invaded, he began to think that while he had been aware of contact, the other had not. And, emboldened, he sent out a tracer. Unconsciously, as the tracer groped, he pivoted his body. It lay--there!

At the second touch he withdrew in the same second, afraid of revelation. But as he returned to probe delicately, ready to flee at the first hint that the other suspected, his belief in temporary safety grew. To his disappointment he could not pierce beyond the outer wall of identity. There was a living creature of a high rate of intelligence, a creature alien to his own thought processes, not too far away. And though his attempts to enter into closer communication grew bolder, he could not crack the barrier which kept them apart. He had long known that contact with the merpeople was on a lower, a far lower, band than they used when among themselves, and that they were only able to "talk" with the colonists because for generations they had exchanged thought symbols with the hoppers and other unlike species. They had been frank in admitting that while Those Others could be aware of their presence through telepathic means, they could not exchange thoughts. So now, his own band, basically strange to this planet, might well go unnoticed by the once dominant race of Astra.

They--or him--or it--were over in that direction, Dalgard was sure of that. He faced northwest and saw for the first time, about a mile away, the swelling of the globe. If the strange flyer reported by the merpeople was beside it, he could not distinguish it from this distance. Yet he was sure the mind he had located was closer to him than that ship.

Then he saw it--a black object rising by stiff jerks into the air as if it were being dragged upward against its inclination. It was too small to be a flyer of any sort. Long ago the colonists had patched together a physical description of Those Others which had assured them that the aliens were close to them in general characteristics and size. No, that couldn't be carrying a passenger. Then what--or why?

The object swung out in a gradually widening circle. Dalgard held to the walled edge of the roof. Something within him suggested that it would be wiser to seek some less open space, that there was danger in that flying box. He released his hold and went to the trap door. It took only a minute to fit his fingers into round holes and tug. Its stubborn resistance gave, and stale air whooshed out in his face as it opened.

In his battle with the door Dalgard had ignored the box, so he was startled when, with a piercing whistle, almost too high on the scale for his ears to catch, the thing suddenly swooped into a screaming dive, apparently heading straight for him. Dalgard flung himself through the trap door, luckily landing on one of the steep, curved ramps. He lost his balance and slid down into the dark, trying to brake his descent with his hands, the eerie screech of the box trumpeting in his ears.

There was little light in this section of the cone building, and he was brought up with bruising force against a blank wall two floors below where he had so unceremoniously entered. As he lay in the dark trying to gasp some breath back into his lungs, he could still hear the squeal. Was it summoning? There was no time to be lost in getting away.
