Dalgard, startled, stared at his companion. Sssuri was still by the grille, watching that archway through which the devil had disappeared.

"What kind of help?" For a moment Dalgard pictured the monster returning at the head of a regiment of its kind, able to tear out this grille and get at their soft-fleshed enemies behind it.

"Safety--protection," Sssuri told him. "And I think that the place to which it now flees is one we should know."

"Those Others?" The sun had not clouded, it still streamed down in the torrid heat of early afternoon, warm on their heads and shoulders. Yet Dalgard felt as chill as if some autumn wind had laid its lash across the small of his back.

"_They_ are not here. But they have been--and it is possible that they return. The devil goes to where it expects to find them."

Sssuri was already on his way, running about the arena's curve to reach the point above the archway through which the snake-devil had raced. Dalgard padded after him, bow in hand. He trusted Sssuri implicitly when it came to tracking. If the merman said that the snake-devil had a definite goal in view, he was right. But the scout was still a little bemused by a monster who was able to have any goal except the hunting and devouring of meat. Either the one who fled was a freak among its kind or--There were several possibilities which could answer that "or," and none of them were very pleasant to consider.

They reached the section above the archway and climbed the tiers of seat benches to the top of the wall. Only to see no exit below them.

In fact nothing but a wide sweep of crushed brown tangle which had once been vegetation. It was apparent that there was no door below.

Sssuri sped down again. He climbed the grille and was on his way to the sand when Dalgard caught up with him. Together they ventured into the underground pa.s.sage which the snake-devil had chosen.

The stench of the lair was thick about them. Dalgard coughed, sickened by the foul odor. He was reluctant to advance. But, to his growing relief, he discovered that it was not entirely dark. Set in the roof at intervals were plates which gave out a violet light, making a dim twilight which was better than total darkness.

It was a straight pa.s.sage without any turns or openings. But the horrible odor was constant, and Dalgard began to think that they might be running head-on into another lair, perhaps one as well populated as that they had left behind them. It was against nature for the snake-devils he had known to lair under cover; they preferred narrow rocky places where they could bask in the sun. But then the devil they now pursued was no ordinary one.

Sssuri rea.s.sured him. "There is no lair, only the smell because they have come this way for many years."

The pa.s.sage opened into a wide room and here the violet light was stronger, bright enough to make plain the fact that alcoves opened off it, each and every one with a barred grille for a door. There was no mistaking that once this had been a prison of sorts.

Sssuri did no exploring but crossed the room at his shuffling trot, which Dalgard matched. The way leading out on the opposite side slanted up, and he judged it might bring them out at ground level.

"The devil waits," Sssuri warned, "because it fears. It will turn on us when we come. Be ready--"

They were at another door, and before them was a long corridor with tall window openings near the ceiling which gave admittance to the sunlight. After the gloom of the tunnel, Dalgard blinked. But he was aware of movement at the far end, just as he heard the hissing scream of the monster they trailed.

TREASURE HUNT

Raf, squatting on a small, padded platform raised some six inches from the floor, tried to study the inhabitants of the room without staring offensively. At the first glance, in spite of their strange clothing and their odd habit of painting their faces with weird designs, the city people might have been of his own species. Until one saw their too slender hands with the three equal-length fingers and thumb, or caught a glimpse, under the elaborate head coverings, of the stiff, spiky substance which served them for hair.

At least they did not appear to be antagonistic. When they had reached the roof top where the Terrans had landed their flitter, they had come with empty hands, making gestures of good will and welcome. And they had had no difficulty in persuading at least three of the exploring party to accompany them to their own quarters, though Raf had been separated from the flyer only by the direct order of Captain Hobart, an order he still resented and wanted to disobey.

The Terrans had been offered refreshment--food and drink. But knowing the first rule of stellar exploration, they had refused, which did not mean that the hosts must abstain. In fact, Raf thought, watching the aliens about him, they ate as if such a feast were novel. His two neighbors had quickly divided his portion between them and made it disappear as fast, if not faster, than their own small servings.

At the other end of the room Lablet and Hobart were trying to communicate with the n.o.bles about them, while Soriki, a small palm recorder in his hand, was making a tape strip of the proceedings.

Raf glanced from one of his neighbors to the other. The one on his right had chosen to wear a sight-torturing shade of crimson, and the material was wound in strips about his body as if he were engulfed in an endless bandage. Only his fluttering hands, his three-toed feet and his head were free of the supple rolls. Having selected red for his clothing, he had picked a brilliant yellow paint for his facial makeup, and it was difficult for the uninitiated to trace what must be his normal features under that thick coating of stuff which fashioned a masklike strip across his eyes and a series of circles outlining his mouth, circles which almost completely covered his beardless cheeks.

More twists of woven fabric, opalescent and changing color as his head moved, made a turban for his head.

Most of the aliens about the room wore some variation of the same bandage dress, face paint, and turban. An exception, one of three such, was the feaster on Raf's left.

His face paint was confined to a conservative set of bars on each cheek, those a stark black and white. His sinewy arms were bare to the shoulder, and he wore a sh.e.l.l of some metallic substance as a breast-and back-plate, not unlike the very ancient body armor of Raf's own world. The rest of his body was covered by the bandage strips, but they were of a dead black, which, because of the natural thinness of his limbs, gave him a rather unpleasant resemblance to a spider.

Various sheaths and pockets hung from a belt pulled tight about his wasp middle, and a helmet of the metal covered his head. Soldier? Raf was sure that his guess was correct.

The officer, if officer he was, caught Raf's gaze. His small round mouth gaped, and then his hands, with a few quick movements which Raf followed, fascinated, pantomimed a flyer in the air. With those talking fingers, he was able to make plain a question: was Raf the pilot of the flitter?

The pilot nodded. Then he pointed to the officer and forced as inquiring an expression as he could command.

The answer was sketched quickly and readably: the alien, too, was either a pilot or had some authority over flyers. For the first time since he had entered this building, Raf knew a slight degree of relaxation.

The wrinkleless, too smooth skin of the alien was a darkish yellow.

His painted face was a mask to frighten any sensible Terran child; his general appearance was not attractive. But he was a flyer, and he wanted to talk shop, as well as they could with no common speech.

Since the scarlet-wound n.o.bleman on Raf's right was completely engrossed in the feast, pursuing a few sc.r.a.ps avidly about the dish, the Terran gave all his attention to the officer.

Twittering words poured in a stream from the warrior's lips. Raf shook his head regretfully, and the other jerked his shoulders in almost human impatience. Somehow that heartened Raf.

With many guesses to cover gaps, probably more than half of which were wrong, Raf gathered that the officer was one of a very few who still retained the almost forgotten knowledge of how to pilot the remaining airworthy craft in this crumbling city. On their way to the building with the curved roof, Raf had noted the evidences that the inhabitants of this metropolis could not be reckoned as more than a handful and that most of these now lived either within the central building or close to it. A pitiful collection of survivors lingering on in the ruins of their past greatness.

Yet he was impressed now by no feeling that the officer, eagerly trying to make contact, was a degenerate member of a dying race. In fact, as Raf glanced at the aliens about the room, he was conscious of an alertness, of a suppressed energy which suggested a young and vigorous people.

The officer was now urging him to go some place, and Raf, his dislike for being in the heart of the strangers' territory once more aroused, was about to shake his head in a firm negative when a second idea stopped him. He had resisted separation from the flitter. Perhaps he could persuade the alien, under the excuse of inspecting a strange machine, to take him back to the flyer. Once there he would stay. He did not know what Captain Hobart and Lablet thought they could accomplish here. But, as for himself, Raf was sure that he was not going to feel easy again until he was across the northern mountain chain and coming in for a landing close by the _RS 10_.

It was as if the alien officer had read his thoughts, for the warrior uncrossed his black legs and got nimbly to his feet with a lithe movement, which Raf, cramped by sitting in the unfamiliar posture, could not emulate. No one appeared to notice their withdrawal. And when Raf hesitated, trying to catch Hobart's eye and make some explanation, the alien touched his arm lightly and motioned toward one of the curtained doorways. Conscious that he could not withdraw from the venture now, Raf reluctantly went out.

They were in a hall where bold bands of color interwove in patterns impossible for Terran eyes to study. Raf lowered his gaze hurriedly to the gray floor under his boots. He had discovered earlier that to try to trace any thread of that wild splashing did weird things to his eyesight and awakened inside him a sick panic. His s.p.a.ce boots, with the metal, magnetic plates set in the soles, clicked loudly on the pavement where his companion's bare feet made no whisper of sound.

The hall gave upon a ramp leading down, and Raf recognized this. His confidence arose. They were on their way out of the building. Here the murals were missing so that he could look about him for reference points.

He was sure that the banquet hall was some ten stories above street level. But they did not go down ten ramps now. At the foot of the third the officer turned abruptly to the left, beckoning Raf along.

When the Terran remained stubbornly where he was, pointing in the direction which, to him, meant return to the flitter, the other made gestures describing an aircraft in flight. His own probably.

Raf sighed. He could see no way out unless he cut and ran. And long before he reached the street from this warren they could pick him up.

Also, in spite of all the precautions he had taken to memorize their way here, he was not sure he could find his path back to the flyer, even if he were free to go. Giving in, he went after the officer.

Their way led out on one of the spider-web bridges which tied building and tower into the complicated web which was the city. Raf, as a pilot of flitter, had always believed that he had no fear of heights. But he discovered that to coast above the ground in a flyer was far different than to hurry at the pace his companion now set across one of these narrow bridges suspended high above the street. And he was sure that the surface under them vibrated as if the slightest extra poundage would separate it from its supports and send it, and them, crashing down.

Luckily the distance they had to cover was relatively short, but Raf swallowed a sigh of relief as they reached the door at the other end.

They were now in a tower which, unluckily, proved to be only a way station before another swing out over empty s.p.a.ce on a span which sloped down! Raf clutched at the guide rail, the presence of which suggested that not all the users of this road were as nonchalant as the officer who tripped lightly ahead. This must explain the other's bare feet--on such paths they were infinitely safer than his own boots.

The downward sloping bridge brought them to a square building which somehow had an inhabited look which those crowding around it lacked.

Raf gained its door to become aware of a hum, a vibration in the wall he touched to steady himself, hinting at the drive of motors, the throb of machinery inside the structure. But within, the officer pa.s.sed along a corridor to a ramp which brought them out, after what was for Raf a steep climb, upon the roof. Here was not one of the tongue-shaped craft such as had first met them in the city, but a gleaming globe. The officer stopped, his eyes moving from the Terran to the machine, as if inviting Raf to share in his own pride. To the pilot's mind it bore little resemblance to any form of aircraft past or present with which he had had experience in his own world. But he did not doubt that it was the present acme of alien construction, and he was eager to see it perform.

He followed the officer through a hatch at the bottom of the globe, only to be confronted by a ladder he thought at first he could not climb, for the steps were merely toe holds made to accommodate the long, bare feet of the crew. By snapping on the magnetic power of his s.p.a.ce boots, Raf was able to get up, although at a far slower speed than his guide. They pa.s.sed several levels of cabins before coming out in what was clearly the control cabin of the craft.

To Raf the bank of unfamiliar levers and b.u.t.tons had no meaning, but he paid strict attention to the gestures of his companion. This was not a s.p.a.ce ship he gathered. And he doubted whether the aliens had ever lifted from their own planet to their neighbors in this solar system. But it was a long-range ship with greater cruising power than the other flyer he had seen. And it was being readied now for a voyage of some length.

The Terran pilot squatted down on the small stool before the controls.

Before him a visa plate provided a clear view of the sky without and the gathering clouds of evening. Raf shifted uncomfortably. That signal of the pa.s.sing of time triggered his impatience to be away--back to the _RS 10_. He did not want to spend the night in this city. Somehow he must get the officer to take him back to the flitter--to be there would be better than shut up in one of the alien dwellings.
