There was, oddly enough, no landing strip within the city. The globe coasted over the rough oval and came down in open fields to the west. It was a maneuver which Raf copied, though he first dropped a flare as a precaution and brought the flier down in its red glare, with the warrior expressing shrill disapproval.
"I don't think they like fireworks," Soriki remarked.
Raf snorted. "So they don't like fireworks! Well, I don't like crack-ups, and I'm the pilot!" But he didn't believe that the com-tech was really protesting. Soriki had been very quiet since they had witnessed the attack on the island.
"Grim-looking place," was his second comment as they touched ground.
Since Raf privately had held that opinion of all the alien settlements he had so far seen, he agreed. Their two alien passengers were out of the flitter as soon as he opened the bubble shield. And as they stood by the Terran flyer, they held their weapons ready, facing out into the dusk as if they half expected trouble. After the earlier episode that day, Raf did not wonder at their preparedness. Terror begets terror, and ruthlessness arouses retaliation in kind.
"Kurbi! Soriki!" Hobart's voice sounded out of the shadows. "Stay where you are for the present."
Soriki settled deeper in his seat. "He doesn't have to tell me to brake jets," he muttered. "I like it here—"
Raf did not need to echo that. He had a strong surmise that had he been tempted to roam away from the flitter the move would not have been encouraged by the alien guardsmen. If this was their treasure city, they would not welcome any independent investigation by strangers.
When the captain joined them, he was accompanied by the officer who had first shown Raf the globe. And the warrior was either disturbed or angry, for he was talking in a steady stream and his hands were whirling in explanatory gestures.
"They didn't like that flare," Hobart remarked. But there was no reproof in his words. As a spacer pilot he knew that Raf had only done what duty demanded. "We're to remain here—for the night."
"Where's Lablet?" Soriki wanted to know.
"He's staying with Yussoz, the alien commander. He thinks he has the language problem about solved."
"Good enough." Soriki pulled out his bed roll. "We're out of touch with the ship—"
There was a second of silence, unduly prolonged it seemed to Raf. Then Hobart spoke:
"We couldn't expect to keep in call forever. The best com has its range. When did you lose contact?"
"Just before these wrapped-up heroes played with fire back there. I gave the boys all I knew up until then. They know we were headed west, and they had us beamed as long as they could."
So it wasn't too bad, thought Raf. But he didn't like it, even with that mitigating factor. To all purposes the four Terrans were now surrounded by some twenty times their number, in an unknown country, out of all communication with the rest of their kind. It could add up to disaster.

SEA GATE
"What is it?" Dalgard asked his question as Sssuri, his attention still on their back trail, stole along cautiously on a retracing of their path.
But that retreat ended abruptly with the merman plastered against the wall, his whole shadowy form a tense warning which stopped Dalgard short. In that moment the answer flashed from mind to mind.
"There are those which follow—"
"Snake-devils? Those Others?" The colony scout supplied the only two explanations he had, sending his own thought out questing. But as usual he could not hope to equal the more sensitive merman whose race had always used that form of communication.
"Those who have long haunted the darkness," was the only reply he could get.
But Sssuri's actions were far more indicative of danger. For the merman turned and caught at Dalgard, pulling the larger colonist along a step or two with the urgency of his grip.
"We cannot return this way—and we must travel fast!"
For Sssuri who would face and had faced up to a snake-devil with a spear his sole weapon, this timidity was new. Dalgard was wise enough to accept his verdict of the wisdom of flight. Together they ran along the underground corridor, soon putting a mile between them and the point where the merman had first taken alarm.
"From what do we flee?" As the merman began to slacken pace, Dalgard sent that query.
"There are those who live in this darkness. By one, or by two, we could speedily remove them from life. But they hunt in packs and they are as greedy for the kill as are the snake-devils scenting meat. Also they are intelligent. Once, long before the days of burning, they served Those Others as hunters of game. And Those Others tried to make them ever more intelligent and crafty so they might be sent to hunt without a huntsman. At last they grew too knowing for their masters. Then Those Others, realizing their menace, tried to kill them all with traps and tricks. But only the most stupid and the slowest were so disposed of. The others withdrew into underground ways such as this, venturing forth only in the dark of night."
"But if they are intelligent," countered the scout, "why can they not be reached by the mind touch?"
"Through the years they have developed their own ways of thought. And these are not the simple creatures of the sun, or such as the runners. Once they were taught to answer only to Those Others. Now they answer only to each other. But"—he spread out his hands in one of his quick, nervous gestures—"to those who are cornered by one of their packs, they are sudden death!"
Since they could not, by Sssuri's reckoning, turn back, there was only one course before them, to follow the passage they had chanced upon. The merman was certain that it underran the river and that eventually they would reach the sea—unless some side turn before that point would make them free in the countryside once more.
Dalgard doubted if it had ever been a well-used way. And the presence of earth falls here and there, over which they stumbled and clawed their way, led him to consider the wisdom of keeping on to what might be a dead end. But his trust in Sssuri's judgment was great, and as the merman plowed forward with every appearance of confidence, he continued to trot along without complaint.
They snatched moments of rest, taking turns at guard. But the walls about them were so unchanging that it was hard to measure time or distance. Dalgard chewed at his emergency rations, a block of dried meat and fruit pounded together to an almost rocklike consistency, and tried to make the crumbs he sucked loose satisfy his growing hunger.
The passageway was growing damper; water trickled down the walls and gathered in fetid pools on the floor. Dalgard's dislike of the place grew. His shoulders hunched involuntarily as he strode along, for his imagination pictured the rock above them giving away to dump tons of the oily river water down to engulf them. But though Sssuri avoided splashing through the pools wherever he might, he did not appear to find anything upsetting about the moisture.
At last the human could stand it no longer. "How much farther to the sea?" he asked without any hope of a real answer.
As he had expected him to do, Sssuri shrugged. "We should be close. But having never trod this way before, how can I tell you?"
Once more they rested, choosing a stretch which was reasonably dry, munching their dried food and drinking sparingly from the stoppered duocorn horns which swung from their belts. A man would have to be dying of thirst, Dalgard thought, before he would palm up any of the stagnant water from the passage pools.
He drifted off into a troubled sleep in which he fled beneath a sky which was a giant lid in the hand of an unseen enemy, a lid which was slowly lowered to crush him flat. He awoke with a start to find Sssuri's cool, scaled fingers stroking his shoulder.
"Dream demons walk these roads." The words drifted into his half-awake mind.
"They do indeed," he roused to answer.
"It is always so where Those Others have been. They leave behind them the thoughts which breed such dreams to trouble the sleep of those who are not of their kind. Let us go. I would like to be out of this place under the clean sky, where no ancient wi
ckedness hangs to poison the air and thought."
Either the merman had miscalculated the direction of their route or the river mouth was much farther from the inland city than they had believed, for, though they pushed on for what seemed like weary hours, they came to no upward slope, no exit to the world they knew.
Instead Dalgard began to realize that just the opposite was true. At last he could stand it no longer and broke out with what he feared, hoping that Sssuri would deny that fear.
"We are going downhill!"
To his disappointment the merman agreed. "It has been so for the last thousand of our paces. It is my belief that this leads not to the sun but out under the sea."
Dalgard missed a step. To Sssuri the sea was home and perhaps the thought of being under its floor was not disturbing. The land-born human was not so prepared. If he had experienced discomfort under the river, what would it be like under the ocean? His terrifying dream of a lid being pressed down upon him flashed back into his mind. But his companion was continuing:
"There will be doors, perhaps into the sea itself."
"For you," Dalgard pointed out, "but I am no dweller in the depths."
"Neither were Those Others, yet they used these ways. And I tell you"—in his earnestness the merman laid his hand once more on Dalgard's arm—"to turn back now is out of the question. The death which haunts the darkness is still sniffing out our trail."
Dalgard glanced involuntarily over his shoulder. By the faint and limited light of the purple disks he could see little or nothing. An army might creep there undetected.
"But—" His protest was in answer to the merman's seeming unconcern.
Sssuri at the first intimation that the hunters were behind them had shown wariness. Now he did not appear to care.
"They had fed," he replied. "Scouts follow because we are something new and thus suspect. When hunger rises once more in them, and their scouts report that we are meat, then is the time to draw knives and prepare for battle. But before that hour we may have won free. Let us search for the gate we now need."
However confident the merman might be, Dalgard could not match that confidence. In the open air he would have faced a snake-devil four times his size without any more emotion than a hunter's instinctive caution. But here in the dark, unable to rid himself of the belief that thousands of tons of sea water hung over his head, he found himself starting at any sound, his knife bare and ready in his sweating hand.
He noted that Sssuri had stepped up the pace, passing into his sure-footed glide which made Dalgard exert himself to keep up. Before them the corridor stretched without a break. The merman's promised exit, if it existed, was still out of sight.
It was difficult to gauge time in this dark hall, but Dalgard thought that they were at least an hour farther on their way when Sssuri paused abruptly once more, his head cocked in a listening attitude, as if he caught some whisper of sound too rarefied for his human companion.
"Now—" the thought hissed as if he spat the words, "they hunger—and they hunt!"
He bounded forward with a spurt, which Dalgard copied, and they ran lightly, the dust undisturbed in years puffing up beneath the merman's bare, scaled feet and Dalgard's hide boots. Still the unbroken walls, the feeble patches of violet in the ceiling. But no exit. And what good would any exit do him, Dalgard thought, if it opened under the sea?
"There are islands off the coast—many islands—" Sssuri caught him up. "It is in my mind that we shall find our door on one of those. But—run now, knife brother, for those at our heels awake and thirst for flesh and blood. They have decided that we are not to be feared but may be run down for their pleasure."
Dalgard weighed his knife in his hand. "They shall find us with fangs," he promised grimly.
"It will be better if they do not find us at all," returned Sssuri.
A burning arch of pain encased Dalgard's lower ribs, and his breath came in gusts of hastily sucked air as their flight kept on, down the endless corridor. Sssuri was also showing signs of the grueling pace, his round head bent forward, his furred legs pumping as if only his iron will kept them moving. And the determination which kept him going was communicated to the scout as a graver warning than any thought message of fear.
They were passing under one of the infrequent violet lights when Dalgard got something else—a mental thrust so quick and sharp it was as if a sword had cut through the daze of fatigue to reach his brain. Yet that had not come from Sssuri, for it was totally alien, wavering on a band so near the extreme edge of his consciousness that it pricked, receded, and pricked again as a needle might.
This was no message of fear or warning, but of implacable stubbornness and ravening hunger. And in that instant Dalgard knew that it came from what was sniffing out their trail, and he no longer wondered that the hunters were immune to other mental contact. One could not reason with—that!
He spurted forward, matching the merman's acceleration of speed. But to Dalgard's horror he saw that his companion now ran with one hand brushing along the wall, as if he needed that support.
"Sssuri!"
His thought met a wall of concentration through which he could not break. In a way he was reassured—for a moment, until another of those stabs from their pursuers struck him. He longed to look back, to see what hunted them. But he dared not break stride to do that.
"Ahhhh!" The welcoming cry from Sssuri brought his attention back to his companion as the merman broke into a wild run.
Dalgard summoned up his last rags of energy and coursed after him. Sssuri had halted before a dark lump which protruded from the side of the corridor.
"A sea lock!" Sssuri's claws were clicking over the surface of the hatch, seeking the secret of its latch.
Panting, Dalgard leaned against the opposite wall. Just as a protest formed in his mind he heard something else, the pad of feet, many feet, echoing down the corridor. And somehow he was able now to look.
Round spots of light, dull, greenish, close to the ground, as if someone had flung a handful of phosphorescence into the dark. But this was no phosphorescence! Eyes! Eyes—he tried to count and knew it was impossible to so reckon the number of the pack that ran mute but ready. Nor could he distinguish more than a very shadowy glimpse of forms which glided close to the ground with an unpleasant sinuosity.
"Ahhhhh!" Again Sssuri's paean of triumph.
There was the grate of unwilling metal forced to move, a puff of air redolent with the sea striking their bodies in chill threat, the brightness of violet light stepped up to a point far beyond the lamps in the corridor.
With it came no rush of drowning water as Dalgard had half expected, and when the merman clambered through the hatch he prepared to follow, well aware that the eyes, and the pattering feet which bore them, were now almost within range.
There was a snarl from the passage, and a black thing sprang at the scout. Without clear sight of what he was fighting, he struck down with his knife and felt it slit flesh. The snarl was a scream of rage as the creature twisted in midair for a second try at him. In that instant Sssuri, leaning halfway out of the hatch, struck in his turn, thrusting his bone knife into shadows which now boiled with life.
Dalgard leaped for the lock door, kicking out swiftly and feeling the toe of his boot contact with a crunch against one of those darting shades, sending it back end over end into the press where its fellows turned snapping upon it. Then Sssuri grabbed at him, bringing him in, and together they slammed the hatch, feeling it shake with the shock of thudding bodies as the pack outside went mad in their frustration.
While the merman fastened the locking bar, bringing out of the long-motionless metal another protesting screech, Dalgard had a chance to look about him. They were in a room some eight or nine feet long, the violet light showing up well tangles of equipment hanging from pegs on the walls, a pile of small cylinders on the floor. At the far end of the chamber was another hatch door, locked with the same type of bar as Sssuri had just lowered to seal t
he inner one. The merman nodded to it.
"The sea—"
Dalgard slid his knife back into its sheath. So the sea lay beyond. He did not welcome the thought of passing through that door. Like all of his race he could swim—perhaps his feats in the water would have astonished the men of the planet from which his tribe had emigrated. But unlike the mermen, he was not sea-born, nor equipped by nature with a secondary breathing apparatus to make him as free in the world of water as he was on land. Sssuri might crawl through that hatch without fear. For Dalgard it was as big a test as to turn and face what now raged in the corridor on the inner side.
"There is no hope that they will go now," Sssuri answered his vague question. "They are stubborn. And hours—or even days—will mean nothing. Also they can leave a guard there and rove at will, to return upon signal. That is their way."
This left only the sea door. Sssuri padded across the chamber and reached up to free one of the strange objects dangling from the wall pegs. Like all things made of the marvelous substance used by Those Others for any article which might be exposed to the elements, it seemed as perfect as on the day it had first been hung there, though that date might be a hundred or more Astran years earlier. The merman uncoiled a length of thin, flexible piping which joined a two-foot canister with a flat piece of metallic fabric.
"Those Others could not breathe under the water, as you cannot," he explained as he worked deftly and swiftly. "Within my own memory we have trapped their scouts wearing aids such as these so that they might spy upon our safe places. But their last foray was some years ago and at that time we taught them such a lesson that they have not dared to return. Since they are not unlike you in body and since you breathe the same air aboveground, there is no reason why this should not take you out of here."
Dalgard accepted the apparatus. A couple of elastic metal bands fastened the canister to the chest of the wearer. The fabric molded into a perfect, tight face mask as it touched the skin.
