the outer hall the merman approached the now dead snake-devil and jerked from its loose skin the arrow which had killed it. Loosing the head of his ruined spear from his belt, he dug and gouged at the small wound, tearing it so that its original nature was concealed forever. Then they retraced their way through the underground passages until they reached the sanded arena. Already insects buzzed hungrily about the hulks of the dead monsters.
There was a shrill squeal as the remaining infant reptile fled from the pouch where it had hidden. Sssuri hurled his knife, and the blade caught the small devil above the shoulder line, half cutting, half snapping its tender neck, so that it bounded aimlessly on to crash against the wall and fall back squirming feebly.
They collected the darts which had killed the others. Dalgard took the opportunity to study those bands on the forearms of the adults. To his touch they had the slick smoothness of metal, yet he was unfamiliar with the material. It possessed the ruddy fire of copper, but through it ran small black veins. He would have liked to have taken one with him for investigation, but it was out of the question to pry it off that scaled limb.
Sssuri straightened up from his last gruesome bit of stage-setting with a sigh of relief. “Go ahead.” He pointed to one of the other archways. “I will confuse the trail.”
Dalgard obeyed, treading as lightly as he could, avoiding all stretches in which he could leave a clear print. Sssuri ran lightly back and forth mixing the few impressions to the best of his ability.
They backtracked to the river, retrieved the boat and recrossed, to leave the city behind and strike into the open country beyond its sinister walls. Night was falling, and Dalgard was very glad that he was not to spend the time of darkness within those haunted buildings. But he knew that it was more than a dislike for being shut up in the alien dwellings which had brought Sssuri out into the fields. The second part of their plan must be put into operation.
While Dalgard willed his body motionless, the merman lay relaxed upon the ground before him as he might have floated upon his beloved waves in some secluded cove. His brilliant eyes were closed. Yet Dalgard knew that Sssuri was far from asleep, and with all his own power he tried to join in the broadcast: that urgency which should send some hopper, some night runner, on to spread the rumor that there was trouble in the north, that danger existed and must be investigated. They had already met one colony of runners ranging southward to escape. But if they could send another such tribe traveling, arouse and aim south a hopper exodus, the story would spread until the fringe would reach the animals who lived in peace within touch of Homeport.
The sun was gone, the dark gathered fast. Dalgard could not even see the clustered buildings of the city now. And since he lacked Sssuri’s range and staying power, he had no idea whether their efforts had met with even a shadow of success. He shivered in the bite of the wind and dared to lay his hand on Sssuri’s shoulder, feeling anew the electric shock of warmth and bursting life which was always there.
Having so broken the other’s absorption he asked a question: “Would it not be well, brother of the knife, if with the rising sun you returned to the sea and struck out to join your tribesmen, leaving me here to watch until you return?”
Sssuri’s answer came with a speed which suggested that he, too, had been considering that problem. “We shall see what happens with the sun’s rising. It is true that in the sea I can travel with greater speed, that there are hunting parties of my people striking into these waters. But they will not come to this city without good reason. It is an accursed place.”
With the early morning the city drew them once more. Dalgard’s curiosity pulled him to that storehouse. He could not stifle the hope that with luck he might find something there which would solve their problem for them. If there could only be a way to avoid open conflict with Those Others, some solution whereby the aliens need never know of the existence of the Colony. For so many generations, even centuries, the aliens had been confined, or had confined themselves, safely overseas on the western continent. Perhaps if now they were faced by some new catastrophe, they would never attempt to come east again. He had visions of discovering and activating some trap set to protect their treasures which could be turned against them. But he realized that he lacked the technical knowledge which would have aided him in the search for such a weapon.
The remnants of Terran science and mechanics, which the outlaws had brought with them from their native world, had been handed on; the experiments they had managed since with crude equipment had been carefully recorded, and he was acquainted with the outlines of most of them. But the few destructive arms they had imported were long since worn out or lacked charges, and they had not been able to duplicate them. Just as they had torn asunder the ship in which they had crossed space, to use its parts for the building of Homeport, so had they hoarded all else they had brought. But they were limited by lack of materials on Astra, and their fear of the knowledge of the aliens had kept them from experimenting with things found in the ruins.
There might be hundreds of objects on the shelves of that storage place, which, properly used, would reduce not only just the room and its contents to glowing slag, but take half the city with it. But he had no idea which, or which combination, would do it.
And here Sssuri could be no help. The mermen had made great strides forward in biological and mental sciences, but mechanics was a closed section of learning because of their enforced habitat under the sea, and of machines they knew less than the colonists.
“I have been thinking—” Sssuri broke into his companion’s chain of reasoning, “of what we may do. And perhaps there is a way to reach the sea more swiftly than by returning overland.”
“Downriver? But you said that way may have its watching devices.”
“Which would be centered on objects coming upstream, not down. But in this city there should be yet another way—”
He did not enlarge upon that, but since he apparently knew what he was doing, Dalgard let him play guide once more. They recrossed the sluggish river, the scout looking into its murky depths with little relish for it as a means of transportation. Though it had an oily, flowing current, there was a suggestion of stagnant water with unpleasant surprises waiting beneath its turgid surface.
For the second time they entered the arena. Avoiding the bodies, Sssuri made a circuit of the sanded floor. He did not turn in at the archway which led to the storage place, but paused before another as if there lay what he had been searching for.
Dalgard’s less sensitive nostrils picked up a new scent, the not-to-be-missed fetor of damp underground ways where water stood. The merman edged around a barred gate as Dalgard sniffed again. The smell of damp was crossed by other and even less appetizing odors, but he did not catch the stench of the snake-devils. And, relying on Sssuri’s judgment, he followed the merman into the dark.
Once again patches of violet light glimmered over their heads as the passage narrowed and sloped downward. Dalgard tried to remember the general geography of the section which was above them now. He had assumed that this way with its dank chill must give on the river. But when they had pattered on for a long distance, he knew that either they had passed beneath the stream or that he was totally lost as to direction.
As their eyes adjusted to the gloom of the passage the violet light grew stronger. So Dalgard saw clearly when Sssuri whirled and faced back along the way they had come, his body in a half crouch, his knife ready in his hand.
Dalgard, his bow useless in the damp, drew his own sword-knife. But, though his mind probed and he listened, he could sense or hear nothing on their trail.
CHAPTER 8
Airlift
They were air-borne once more, but Raf was not pleased. In the seat beside him, which Captain Hobart should be occupying, there now squirmed an alien warrior who apparently was uncomfortable in the chair-like depression so different from the low stools he was accustomed to. Soriki was still in the second passenger place, but he, too, shared that with another of the men from the city who rested across bony knees a strange weapon rather like a Terran rifle.
No, the spacemen were not prisoners. According to the official statement they were allies.
