Dane put the mug back on the heating unit and sat down at the other end of the table. He did not have the heart to shake Tau into wakefulness—let the poor devil get a slice of bunk time, he certainly needed it after the fatigues of the past four days.
Van Rycke passed along the corridor on his way to the hydro, Sinbad at his heels. But in a moment the cat was back, leaping up on Dane's knee. He did not curl up, but rubbed against the young man's arm, finally reaching up with a paw to touch Dane's chin, uttering one of the soundless, mews which were his bid for attention.
"What's the matter, boy?" Dane fondled the cat's ears. "You haven't got a headache—have you?" In that second a wild surmise came into his mind. Sinbad had been planet-side on Sargol as much as he could, and on ship board he was equally at home in all their cabins—could he be the carrier of the disease?
A good idea—only if it were true, then logically the second victim should have been Van, or Dane—whereas Sinbad lingered most of the time in their cabins—not Kosti. The cat, as far as he knew, had never shown any particular fondness for the jetman and certainly did not sleep in Karl's quarters. No—that point did not fit. But he would mention it to Tau—no use overlooking anything—no matter how wild.
It was the sequence of victims which puzzled them all. As far as Tau had been able to discover Mura and Kosti had nothing much in common except that they were crewmates on the same spacer. They did not bunk in the same section, their fields of labor were totally different, they had no special food or drink tastes in common, they were not even of the same race. Frank Mura was one of the few descendants of a mysterious (or now mysterious) people who had had their home on a series of islands in one of Terra's seas, islands which almost a hundred years before had been swallowed up in a series of world-rending quakes—Japan was the ancient name of that nation. While Karl Kosti had come from the once thickly populated land masses half the planet away which had borne the geographical name of "Europe." No, all the way along the two victims had only very general meeting points—they both shipped on the Solar Queen and they were both of Terran birth.
Tau stirred and sat up, blinking bemusedly at Dane, then pushed back his wiry black hair and assumed a measure of alertness. Dane dropped the now purring cat in the Medic's lap and in a few sentences outlined his suspicion. Tau's hands closed about Sinbad.
"There's a chance in that—" He looked a little less beat and he drank thirstily from the mug Dane gave him for the second time. Then he hurried out with Sinbad under one arm—bound for his lab.
Dane slicked up the galley, trying to put things away as neatly as Mura kept them. He didn't have much faith in the Sinbad lead, but in this case everything must be checked out.
When the Medic did not appear during the rest of the ship's day Dane was not greatly concerned. But he was alerted to trouble when Ali came in with an inquiry and a complaint.
"Seen anything of Craig?"
"He's in the lab," Dane answered.
"He didn't answer my knock," Ali protested. "And Weeks says he hasn't been in to see Karl all day—"
That did catch Dane's attention. Had his half hunch been right? Was Tau on the trail of a discovery which had kept him chained to the lab? But it wasn't like the Medic not to look in on his patients.
"You're sure he isn't in the lab?"
"I told you that he didn't answer my knock. I didn't open the panel—" But now Ali was already in the corridor heading back the way he had come, with Dane on his heels, an unwelcome explanation for that silence in both their minds. And their fears were reinforced by what they heard as they approached the panel—a low moan wrung out of unbearable pain. Dane thrust the sliding door open.
Tau had slipped from his stool to the floor. His hands were at his head which rolled from side to side as if he were trying to quiet some agony. Dane stripped down the Medic's under tunic. There was no need to make a careful examination, in the hollow of Craig Tau's throat was the tell-tale red blotch.
"Sinbad!" Dane glanced about the cabin. "Did Sinbad get out past you?" he demanded of the puzzled Ali.
"No—I haven't seen him all day—"
Yet the cat was nowhere in the tiny cabin and it had no concealed hiding place. To make doubly sure Dane secured the panel before they carried Tau to his bunk. The Medic had blacked out again, passed into the lethargic second stage of the malady. At least he was out of the pain which appeared to be the worst symptom of the disease.
"It must be Sinbad!" Dane said as he made his report directly to Captain Jellico. "And yet—"
"Yes, he's been staying in Van's cabin," the Captain mused. "And you've handled him, he slept on your bunk. Yet you and Van are all right. I don't understand that. Anyway—to be on the safe side—we'd better find and isolate him before—"
He didn't have to underline any words for the grim-faced men who listened. With Tau—their one hope of fighting the disease gone—they had a black future facing them.
They did not have to search for Sinbad. Dane coming down to his own section found the cat crouched before the panel of Van Rycke's cabin, his eyes glued to the thin crack of the door. Dane scooped him up and took him to the small cargo space intended for the safeguarding of choice items of commerce. To his vast surprise Sinbad began fighting wildly as he opened the hatch, kicking and then slashing with ready claws. The cat seemed to go mad and Dane had all he could do to shut him in. When he snapped the panel he heard Sinbad launch himself against the barrier as if to batter his way out. Dane, blood welling in several deep scratches, went in search of first aid. But some suspicion led him to pause as he passed Van Rycke's door. And when his knock brought no answer he pushed the panel open.
Van Rycke lay on his bunk, his eyes half closed in a way which had become only too familiar to the crew of the Solar Queen. And Dane knew that when he looked for it he would find the mark of the strange plague on the Cargo-master's body.
Chapter IX
PLAGUE!
Jellico and Steen Wilcox pored over the few notes Tau had made before he was stricken. But apparently the Medic had found nothing to indicate that Sinbad was the carrier of any disease. Meanwhile the Captain gave orders for the cat to be confined. A difficult task—since Sinbad crouched close to the door of the storage cabin and was ready to dart out when food was taken in for him. Once he got a good way down the corridor before Dane was able to corner and return him to keeping.
Dane, Ali and Weeks took on the full care of the four sick men, leaving the few regular duties of the ship to the senior officers, while Rip was installed in charge of the hydro garden.
Mura, the first to be taken ill, showed no change. He was semi-conscious, he swallowed food if it were put in his mouth, he responded to nothing around him. And Kosti, Tau, and Van Rycke followed the same pattern. They still held morning inspection of those on their feet for signs of a new outbreak, but when no one else went down during the next two days, they regained a faint spark of hope.
Hope which was snapped out when Ali brought the news that Stotz could not be roused and must have taken ill during a sleep period. One more inert patient was added to the list—and nothing learned about how he was infected. Except that they could eliminate Sinbad, since the cat had been in custody during the time Stotz had apparently contracted the disease.
Weeks, Ali and Dane, though they were in constant contact with the sick men, and though Dane had repeatedly handled Sinbad, continued to be immune. A fact, Dane thought more than once, which must have significance—if someone with Tau's medical knowledge had been able to study it. By all rights they should be the most susceptible—but the opposite seemed true. And Wilcox duly noted that fact among the data they had recorded.
It became a matter of watching each other, waiting for another collapse. And they were not surprised when Tang Ya reeled into the mess, his face livid and drawn with pain. Rip and Dane got him to his cabin before he blacked out. But all they could learn from him during the interval before he lost consciousness was that his head was bu
rsting and he couldn't stand it. Over his limp body they stared at one another bleakly.
"Six down," Ali observed, "and six to go. How do you feel?"
"Tired, that's all. What I don't understand is that once they go into this stupor they just stay. They don't get any worse, they have no rise in temperature—it's as if they are in a modified form of cold sleep!"
"How is Tang?" Rip asked from the corridor.
"Usual pattern," Ali answered, "He's sleeping. Got a pain, Fella?"
Rip shook his head. "Right as a Com-unit. I don't get it. Why does it strike Tang who didn't even hit dirt much—and yet you keep on—?"
Dane grimaced. "If we had an answer to that, maybe we'd know what caused the whole thing—"
Ali's eyes narrowed. He was staring straight at the unconscious Com-tech as if he did not see that supine body at all. "I wonder if we've been salted—" he said slowly.
"We've been what?" Dane demanded.
"Look here, we three—with Weeks—drank that brew of the Salariki, didn't we? And we—"
"Were as sick as Venusian gobblers afterwards," agreed Rip.
Light dawned. "Do you mean—" began Dane.
"So that's it!" flashed Rip.
"It might just be," Ali said. "Do you remember how the settlers on Camblyne brought their Terran cattle through the first year? They fed them salt mixed with fansel grass. The result was that the herds didn't take the fansel grass fever when they turned them out to pasture in the dry season. All right, maybe we had our 'salt' in that drink. The fansel-salt makes the cattle filthy sick when it's forced down their throats, but after they recover they're immune to the fever. And nobody on Camblyne buys unsalted cattle now."
"It sounds logical," admitted Rip. "But how are we going to prove it?"
Ali's face was black once more. "Probably by elimination," he said morosely. "If we keep our feet and all the rest go down—that's our proof."
"But we ought to be able to do something—" protested Shannon.
"Just how?" Ali's slender brows arched. "Do you have a gallon of that Salariki brew on board you can serve out? We don't know what was in it. Nor are we sure that this whole idea has any value."
All of them had had first aid and basic preventive medicine as part of their training, but the more advanced laboratory experimentation was beyond their knowledge and skill. Had Tau still been on his feet perhaps he could have traced that lead and brought order out of the chaos which was closing in upon the Solar Queen. But, though they reported their suggestion to the Captain, Jellico was powerless to do anything about it. If the four who had shared that upsetting friendship cup were immune to the doom which now overhung the ship, there was no possible way for them to discover why or how.
Ship's time came to have little meaning. And they were not surprised when Steen Wilcox slipped from his seat before the computer—to be stowed away with what had become a familiar procedure. Only Jellico withstood the contagion apart from the younger four, taking his turn at caring for the helpless men. There was no change in their condition. They neither roused nor grew worse as the hours and then the days sped by. But each of those units of time in passing brought them nearer to greater danger. Sooner or later they must make the transition out of Hyper into system space, and the jump out of warp was something not even a veteran took lightly. Rip's round face thinned while they watched. Jellico was still functioning. But if the Captain collapsed the whole responsibility for the snap-out would fall directly on Shannon. An infinitesimal error would condemn them to almost hopeless wandering—perhaps for ever.
Dane and Ali relieved Rip of all duty but that which kept him chained in Wilcox's chair before the computers. He went over and over the data of the course the Astrogator had set. And Captain Jellico, his eyes sunk in dark pits, checked and rechecked.
When the fatal moment came Ali manned the engine room with Weeks at his elbow to tend the controls the acting-Engineer could not reach. And Dane, having seen the sick all safely stowed in crash webbing, came up to the control cabin, riding out the transfer in Tang Ya's place.
Rip's voice hoarsened into a croak, calling out the data. Dane, though he had had basic theory, was completely lost before Shannon had finished the first set of co-ordinates. But Jellico replied, hands playing across the pilot's board.
"Stand-by for snap-out—" the croak went down to the engines where Ali now held Stotz's post.
"Engines ready!" The voice came back, thinned by its journey from the Queen's interior.
"Ought-five-nine—" That was Jellico.
Dane found himself suddenly unable to watch. He shut his eyes and braced himself against the vertigo of snap-out. It came and he whirled sickeningly through unstable space. Then he was sitting in the laced Com-tech's seat looking at Rip.
Runnels of sweat streaked Shannon's brown face. There was a damp patch darkening his tunic between his shoulder blades, a patch which it would take both of Dane's hands to cover.
For a moment he did not raise his head to look at the vision plate which would tell him whether or not they had made it. But when he did familiar constellations made the patterns they knew. They were out—and they couldn't be too far off the course Wilcox had plotted. There was still the system run to make—but snap-out was behind them. Rip gave a deep sigh and buried his head in his hands.
With a throb of fear Dane unhooked his safety belt and hurried over to him. When he clutched at Shannon's shoulder the Astrogator-apprentice's head rolled limply. Was Rip down with the illness too? But the other muttered and opened his eyes.
"Does your head ache?" Dane shook him.
"Head? No—" Rip's words came drowsily. "Jus' sleepy—so sleepy—"
He did not seem to be in pain. But Dane's hands were shaking as he hoisted the other out of his seat and half carried-half led him to his cabin, praying as he went that it was only fatigue and not the disease. The ship was on auto now until Jellico as pilot set a course—
Dane got Rip down on the bunk and stripped off his tunic. The fine-drawn face of the sleeper looked wan against the foam rest, and he snuggled into the softness like a child as he turned over and curled up. But his skin was clear—it was real sleep and not the plague which had claimed him.
Impulse sent Dane back to the control cabin. He was not an experienced pilot officer, but there might be some assistance he could offer the Captain now that Rip was washed out, perhaps for hours.
Jellico hunched before the smaller computer, feeding pilot tape into its slot. His face was a skull under a thin coating of skin, the bones marking it sharply at jaw, nose and eye socket.
"Shannon down?" His voice was a mere whisper of its powerful self, he did not turn his head.
"He's just worn out, sir," Dane hastened to give reassurance. "The marks aren't on him."
"When he comes around tell him the co-ords are in," Jellico murmured. "See he checks course in ten hours—"
"But, sir—" Dane's protest failed as he watched the Captain struggle to his feet, pulling himself up with shaking hands. As Thorson reached forward to steady the other, one of those hands tore at tunic collar, ripping loose the sealing—
There was no need for explanation—the red splotch signaled from Jellico's sweating throat. He kept his feet, holding out against the waves of pain by sheer will power. Then Dane had a grip on him, got him away from the computer, hoping he could keep him going until they reached Jellico's cabin.
Somehow they made that journey, being greeted with raucous screams from the Hoobat. Furiously Dane slapped the cage, setting it to swinging and so silencing the creature which stared at him with round, malignant eyes as he got the Captain to bed.
Only four of them on their feet now, Dane thought bleakly as he left the cabin. If Rip came out of it in time they could land—Dane's breath caught as he made himself face up to the fact that Shannon might be ill, that it might be up to him to bring the Queen in for a landing. And in where? The Terra quarantine was Luna City on the Moon. But let them signal for a set-d
own there—let them describe what had happened and they might face death as a plague ship.
Wearily he climbed down to the mess cabin to discover Weeks and Ali there before him. They did not look up as he entered.
"Old Man's got it," he reported.
"Rip?" was Ali's crossing question.
"Asleep. He passed out—"
"What!" Weeks swung around.
"Worn out," Dane amended. "Captain fed in a pilot tape before he gave up."
"So—now we are three," was Ali's comment. "Where do we set down—Luna City?"
"If they let us," Dane hinted at the worst.
"But they've got to let us!" Weeks exclaimed. "We can't just wander around out here—"
"It's been done," Ali reminded them brutally and that silenced Weeks.
"Did the Old Man set Luna?" After a long pause Ali inquired.
"I didn't check," Dane confessed. "He was giving out and I had to get him to his bunk."
"It might be well to know." The Engineer-apprentice got up, his movements lacking much of the elastic spring which was normally his. When he climbed to control both the others followed him.
Ali's slender fingers played across a set of keys and in the small screen mounting on the computer a set of figures appeared. Dane took up the master course book, read the connotation and blinked.
"Not Luna?" Ali asked.
"No. But I don't understand. This must be for somewhere in the asteroid belt."
Ali's lips stretched into a pale caricature of a smile. "Good for the Old Man, he still had his wits about him, even after the bug bit him!"
"But why are we going to the asteroids?" Weeks asked reasonably enough. "There're Medics at Luna City—they can help us—"
"They can handle known diseases," Ali pointed out. "But what of the Code?"
Weeks dropped into the Com-tech's place as if some of the stiffening had vanished from his thin but sturdy legs. "They wouldn't do that—" he protested, but his eyes said that he knew that they might—they well might.
