But if he could only make the right move--would make it--The scout from Homeport had no idea what was in store for him, but with one of his own breed here and suspicious of the aliens he had at least a slim chance. He snapped the thread of communication. Now he must be ready for any opportunity--

Raf watched that amazing apparition go out of the room below. He was shaking with a chill born of no outside cold. First the shock of hearing that language, queerly accented as the words were, then that sharp contact, mind to mind. He was being clearly warned against revealing himself. The stranger was a Terran, Raf would swear to that.

So somewhere on this world there was a Terran colony! One of those legendary ships of outlaws, who had taken to s.p.a.ce during the rule of Pax, had made the crossing safely and had here established a foothold.

While one part of Raf's brain fitted together the jigsaw of bits and patches of information, the other section dealt with that message of warning the other had beamed to him. The pilot knew that the captive must be in immediate danger. He could not understand all that had happened in that interview with the aliens, but he was left with the impression that the prisoner had been not only tried but condemned.

And it was up to him to help.

But how? By the time he got back to the flitter or was able to find Hobart and the others, it might already be too late. _He_ must make the move, and soon, for there had been unmistakable urgency in the captive's message. Raf's hands fumbled at the grid before him, and then he realized that the opening was far too small to admit him to the room on the other side of the wall.

To return to the underground ways might be a waste of time, but he could see no other course open to him. What if he could not find the captive later? Where in the maze of the half-deserted city could he hope to come across the trail again? Even as he sorted out all the points which could defeat him, Raf's hands and feet felt for the notched steps which would take him down. He had gone only two floors when he was faced with a grille opening which was much larger. On impulse he stopped to measure it, sure he could squeeze through here, if he could work loose the grid.

Prying with one hand and a tool from his belt pouch, he struggled not only against the stubborn metal but against time. That strange mental communication had ceased. Though he was sure that he still received a trace of it from time to time, just enough to rea.s.sure him that the prisoner was still alive. And each time it touched him Raf redoubled his efforts on the metal clasps of the grid. At last his determination triumphed, and the grille swung out, to fall with an appalling clatter to the floor.

The pilot thrust his feet through the opening and wriggled desperately, expecting any moment to confront a reception committee drawn by the noise. But when he reached the floor, the hallway was still vacant. In fact, he was conscious of a hush in the whole building, as if those who made their homes within its walls were elsewhere. That silence acted on him as a spur.

Raf ran along the corridor, trying to subdue the clatter of his s.p.a.ce boots, coming to a downward ramp. There he paused, unable to decide whether to go down--until he caught sight of a party of aliens below, walking swiftly enough to suggest that they too were in a hurry.

This small group was apparently on its way to some gathering. And in it for the first time the Terran saw the women of the aliens, or at least the fully veiled, gliding creatures he guessed were the females of the painted people. There were four of them in the group ahead, escorted by two of the males, and the high fluting of their voices resounded along the corridor as might the cheeping of birds. If the males were colorful in their choice of body wrappings, the females were gorgeous beyond belief, as cloudy stuff which had the changing hues of Terran opals frothed about them to completely conceal their figures.

The harsher twittering of the men had an impatient note, and the whole party quickened pace until their glide was close to an undignified trot. Raf, forced to keep well behind lest his boots betray him, fumed.

They did not go into the open, but took another way which sloped down once more. Luckily the journey was not a long one. Ahead was light which suggested the outdoors.

Raf sucked in his breath as he came out a goodly distance behind the aliens. Established in what was once a court surrounded by the towers and buildings of the city was a miniature of that other arena where he had seen the dead lizard things. The glittering, gayly dressed aliens were taking their places on the tiers of seats. But the place which had been built to accommodate at least a thousand spectators now housed less than half the number. If this was the extent of the alien nation, it was the dregs of a dwindling race.

Directly below where Raf lingered in an aisle dividing the tiers of seats, there was a manhole opening with a barred gate across it, an entrance to the sand-covered enclosure. And fortunately the aliens were all cl.u.s.tered close to the oval far from that spot.

Also the attention of the audience was firmly riveted on events below.

A door at the sand level had been flung open, and through it was now hustled the prisoner. Either the aliens still possessed some idea of fair play or they hoped to prolong a contest to satisfy their own pleasure, for the captive's hands were unbound and he clutched a spear.

Remembering far-off legends of earlier and more savage civilizations on his own world, Raf was now sure that the lone man below was about to fight for his life. The question was, against what?

Another of the mouthlike openings around the edge of the arena opened, and one of the furry people shambled out, weaving weakly from side to side as he came, a spear in his scaled paws. He halted a step or two into the open, his round head swinging from side to side, spittle drooling from his gaping mouth. His body was covered with raw sores and bare patches from which the fur had been torn away, and it was apparent that he had long been the victim of ill-usage, if not torture.

Shrill cries arose from the alien spectators as the furred one blinked in the light and then sighted the man some feet away. He stiffened, his arm drew back, the spear poised. Then as suddenly it dropped to his side, and he fell on his knees before wriggling across the sand, his paws held out imploringly to his fellow captive.

The cries from the watching aliens were threatening. Several rose in their seats gesturing to the two below. And Raf, thankful for their absorption, sped down to the manhole, discovering to his delight it could be readily opened from his side. As he edged it around, there was another sound below. This was no high-pitched fluting from aliens deprived of their sport, but a hissing nightmare cry.

Raf's line of vision, limited by the door, framed a portion of scaled back, as it looked, immediately below him. His hand went to the blast bombs as he descended the runway, and his boots. .h.i.t the sand just as the drama below reached its climax.

The furred one lay p.r.o.ne in the sand, uncaring. Above that mistreated body, the human stood in the half-crouch of a fighting man, the puny spear pointed up bravely at a mark it could not hope to reach, the soft throat of one of the giant lizards. The reptile did not move to speedily destroy. Instead, hissing, it reared above the two as if studying them with a vicious intelligence. But there was no time to wonder how long it would delay striking.

Raf's strong teeth ripped loose the tag end of the blast bomb, and he lobbed it straight with a practiced arm so that the ball spiraled across the arena to come to rest between the ma.s.sive hind legs of the lizard. He saw the man's eyes widen as they fastened on him. And then the human captive flung himself to the earth, half covering the body of the furred one. The reptile grabbed in the same instant, its grasping claws cutting only air, and before it could try a second time the bomb went off.

Literally torn apart by the explosion, the creature must have died at once. But the captive moved. He was on his feet again, pulling his companion up with him, before the startled spectators could guess what had happened. Then half carrying the other prisoner, he ran, not onward to the waiting Raf, but for the gate through which he had come into the arena. At the same time a message beat into the Terran's brain--

"This way!"

Avoiding bits of horrible refuse, Raf obeyed that order, catching up in a couple of strides with the other two and linking his arm through the dangling one of the furred creature to take some of the strain from the stranger.

"Have you any more of the power things?" the words came in the archaic speech of his own world.

"Two more bombs," he answered.

"We may have to blow the gate here," the other panted breathlessly.

Instead Raf drew his stun gun. The gate was already opening, a wedge of the painted warriors heading through, flame-throwers ready. He sprayed wide, and on the highest level. A spout of fire singed the cloth of his tunic across the top of his shoulder as one of the last aliens fired before his legs buckled and he went down. Then, opposition momentarily gone, the two with their semiconscious charge stumbled over the bodies of the guards and reached the corridor beyond.

SURPRISE ATTACK

So much had happened so quickly during the past hour that Dalgard had no chance to plan or even sort out impressions in his mind. He had no guess as to where this stranger, now taking some of the burden of the wounded merman from him, had sprung from. The other's clothing, the helmet covering his head were more akin to those worn by the aliens than they were to the dress of the colonist. Yet the man beneath those trappings was of the same breed as his own people. And he could not believe he was a Peaceman of Pax--all he had done here spoke against those legends of dark Terran days Dalgard had heard from childhood.

But where had he come from? The only answer could be another outlaw colony ship.

"We are in the inner ways," Dalgard tried to reach the mind of the merman as they pounded on into the corridors which led from the arena.

"Do you know these--" He had a faint hope that the sea man because of his longer captivity might have a route of escape to suggest.

"--down to the lower levels--" the thought came slowly, forced out by a weakening will. "Lower--levels--roads to the sea--"

That was what Dalgard had been hoping for, some pa.s.sage which would run seaward and so to safety, such as he had found with Sssuri in that other city.

"What are we hunting?" the stranger broke in, and Dalgard realized that perhaps the other did not follow the mind talk. His words had an odd inflection, a clipped accent which was new.

"A lower way," he returned in the speech of his own people.

"To the right." The merman, struggling against his own weakness, had raised his head and was looking about as one who searches for a familiar landmark.

There was a branching way to the right, and Dalgard swung into it, bringing the other two after him. This was a narrow pa.s.sage, and twice they brushed by sealed doors. It brought them up against a blank wall.

The stranger wheeled, his odd weapon ready, for they could hear the shouts of pursuers behind them. But the merman pulled free of Dalgard and went down on the floor to dig with his taloned fingers at some depressions there.

"Open here," the thought came clearly, "then down!"

Dalgard went down on one knee, able now to see the outline of a trap door. It must be pried up. His sword-knife was gone, the spear they had given him for the arena he had dropped when he dragged the merman out of danger. He looked to the stranger. About the other's narrow hips was slung a belt from which hung pouches and tools the primitive colonist could not evaluate. But there was also a bush knife, and he reached for it.

"The knife--"

The stranger glanced down at the blade he wore in surprise, as if he had forgotten it. Then with one swift movement he drew it from its sheath and flipped it to Dalgard.

On the track behind the clamor was growing, and the colony scout worked with concentration at his task of fitting the blade into the crack and freeing the door. As soon as there was s.p.a.ce enough, the merman's claws recklessly slid under, and he added what strength he could to Dalgard's. The door arose and fell back onto the pavement with a clang, exposing a dark pit.

"Got 'em!" the words burst from the stranger. He had pressed the firing b.u.t.ton of his weapon. Where the pa.s.sage in which they stood met the main corridor, there was an agitated shouting and then sudden silence.

"Down--" The merman had crawled to the edge of the opening. From it rose a dank, fetid smell. Now that the noise in the corridor was stilled Dalgard could hear something: the sound of water.
