n.o.body explained matters to Ross Murdock. The bandaged Hardy was claimed by the doctor and two attendants and carried away, the major walking beside the stretcher, still holding one of the mittened hands in his.

Ross hesitated, sure he was not supposed to follow, but not ready either to explore farther or return to his own room. The sight of Hardy, whoever he might be, had radically changed Ross's conception of the project he had too speedily volunteered to join.

That what they did here was important, Ross had never doubted. That it was dangerous, he had early suspected. But his awareness had been an abstract concept of danger, not connected with such concrete evidence as Hardy crawling through the dark. From the first, Ross had nursed vague plans for escape; now he knew he must get out of this place lest he end up a twin for Hardy.

"Murdock?"

Having heard no warning sound from behind, Ross whirled, ready to use his fists, his only weapons. But he did not face the major, or any of the other taciturn men he knew held positions of authority. The newcomer's brown skin was startling against the neutral shade of the walls. His hair and brows were only a few shades darker; but the general sameness of color was relieved by the vivid blue of his eyes.

Expressionless, the dark stranger stood quietly, his arms hanging loosely by his sides, studying Ross, as if the younger man was some problem he had been a.s.signed to solve. When he spoke, his voice was a monotone lacking any modulation of feeling.

"I am Ashe." He introduced himself baldly; he might have been saying "This is a table and that is a chair."

Ross's quick temper took spark from the other's indifference. "All right--so you're Ashe!" He strove to make a challenge of it. "And what is that supposed to mean?"

But the other did not rise to the bait. He shrugged. "For the time being we have been partnered----"

"Partnered for what?" demanded Ross, controlling his temper.

"We work in pairs here. The machine sorts us ..." he answered briefly and consulted his wrist watch. "Mess call soon."

Ashe had already turned away, and Ross could not stand the other's lack of interest. While Murdock refused to ask questions of the major or any others on that side of the fence, surely he could get some information from a fellow "volunteer."

"What is this place, anyway?" he asked.

The other glanced back over his shoulder. "Operation Retrograde."

Ross swallowed his anger. "Okay, but what do they do here? Listen, I just saw a fellow who'd been banged up as if he'd been in a concrete mixer, creeping along this hall. What sort of work do they do here? And what do we have to do?"

To his amazement Ashe smiled, at least his lips quirked faintly. "Hardy got under your skin, eh? Well, we have our percentage of failures. They are as few as it's humanly possible to make, and they give us every advantage that can be worked out for us----"

"Failures at what?"

"Operation Retrograde."

Somewhere down the hall a buzzer gave a muted whirr.

"That's mess call. And I'm hungry, even if you're not." Ashe walked away as if Ross Murdock had ceased to exist.

But Ross Murdock did exist, and to him that was an important fact. As he trailed along behind Ashe he determined that he was going to continue to exist, in one piece and unharmed, Operation Retrograde or no Operation Retrograde. And he was going to pry a few enlightening answers out of somebody very soon.

To his surprise he found Ashe waiting for him at the door of a room from which came the sound of voices and a subdued clatter of trays and tableware.

"Not many in tonight," Ashe commented in a take-it-or-leave-it tone.

"It's been a busy week."

The room was rather spa.r.s.ely occupied. Five tables were empty, while the men gathered at the remaining two. Ross counted ten men, either already eating or coming back from a serving hatch with well-filled trays. All of them were dressed in slacks, shirt, and moccasins like himself--the outfit seemed to be a sort of undress uniform--and six of them were ordinary in physical appearance. The other four differed so radically that Ross could barely conceal his amazement.

Since their fellows accepted them without comment, Ross silently stole glances at them as he waited behind Ashe for a tray. One pair were clearly Oriental; they were small, lean men with thin brackets of long black mustache on either side of their mobile mouths. Yet he had caught a word or two of their conversation, and they spoke his own language with the facility of the native born. In addition to the mustaches, each wore a blue tattoo mark on the forehead and others of the same design on the backs of their agile hands.

The second duo were even more fantastic. The color of their flaxen hair was normal, but they wore it in braids long enough to swing across their powerful shoulders, a fashion unlike any Ross had ever seen. Yet any suggestion of effeminacy certainly did not survive beyond the first glance at their ruggedly masculine features.

"Gordon!" One of the braided giants swung halfway around from the table to halt Ashe as he came down the aisle with his tray. "When did you get back? And where is Sanford?"

One of the Orientals laid down the spoon with which he had been vigorously stirring his coffee and asked with real concern, "Another loss?"

Ashe shook his head. "Just rea.s.signment. Sandy's holding down Outpost Gog and doing well." He grinned and his face came to life with an expression of impish humor Ross would not have believed possible. "He'll end up with a million or two if he doesn't watch out. He takes to trade as if he were born with a beaker in his fist."

The Oriental laughed and then glanced at Ross. "Your new partner, Ashe?"

Some of the animation disappeared from Ashe's brown face; he was noncommittal again. "Temporary a.s.signment. This is Murdock." The introduction was flat enough to daunt Ross. "Hodaki, Feng," he indicated the two Easterners with a nod as he put down his tray.

"Jansen, Van Wyke." That accounted for the blonds.

"Ashe!" A man arose at the other table and came to stand beside theirs.

Thin, with a dark, narrow face and restless eyes, he was much younger than the others, younger and not so well controlled. He might answer questions if there was something in it for him, Ross decided, and filed the thought away.

"Well, Kurt?" Ashe's recognition was as dampening as it could be, and Ross's estimation of the younger man went up a fraction when the snub appeared to have no effect upon him.

"Did you hear about Hardy?"

Feng looked as if he were about to speak, and Van Wyke frowned. Ashe made a deliberate process of chewing and swallowing before he replied.

"Naturally." His tone reduced whatever had happened to Hardy to a matter-of-fact proceeding far removed from Kurt's implied melodrama.

"He's smashed up ... kaput...." Kurt's accent, slight in the beginning, was thickening. "Tortured...."

Ashe regarded him levelly. "You aren't on Hardy's run, are you?"

Still Kurt refused to be quashed. "Of course, I'm not! You know the run I am in training for. But that is not saying that such can not happen as well on my run, or yours, or yours!" He pointed a stabbing finger at Feng and then at the blond men.

"You can fall out of bed and break your neck, too, if your number comes up that way," observed Jansen. "Go cry on Millaird's shoulder if it hurts you that much. You were told the score at your briefing. You know why you were picked...."

Ross caught a faint glance aimed at him by Ashe. He was still totally in the dark, but he would not try to pry any information from this crowd.

Maybe part of their training was this hush-hush business. He would wait and see, until he could get Kurt aside and do a little pumping.

Meanwhile he ate stolidly and tried to cover up his interest in the conversation.

"Then you are going to keep on saying 'Yes, sir,' 'No, sir,' to every order here----?"

Hodaki slammed his tattooed hand on the table. "Why this foolishness, Kurt? You well know how and why we are picked for runs. Hardy had the deck stacked against him through no fault of the project. That has happened before; it will happen again----"

"Which is what I have been saying! Do you wish it to happen to you?

Pretty games those tribesmen on your run play with their prisoners, do they not?"

"Oh, shut up!" Jansen got to his feet. Since he loomed at least five inches above Kurt and probably could have broken him in two over one ma.s.sive knee, his order was one to be considered. "If you have any complaints, go make them to Millaird. And, little man"--he poked a ma.s.sive forefinger into Kurt's chest--"wait until you make that first run of yours before you sound off so loudly. No one is sent out without every ounce of preparation he can take. But we can't set up luck in advance, and Hardy was unlucky. That's that. We got him back, and that was lucky for him. He'd be the first to tell you so." He stretched. "I'm for a game--Ashe? Hodaki?"

"Always so energetic," murmured Ashe, but he nodded as did the small Oriental.

Feng smiled at Ross. "Always these three try to beat each other, and so far all the contests are draws. But we hope ... yes, we have hopes...."

So Ross had no chance to speak to Kurt. Instead, he was drawn into the knot of men who, having finished their meal, entered a small arena with a half circle of spectator seats at one side and a s.p.a.ce for contestants at the other. What followed absorbed Ross as completely as the earlier scene of the wolf killing. This too was a fight, but not a physical struggle. All three contenders were not only unlike in body, but as Ross speedily came to understand, they were also unlike in their mental approach to any problem.
