Chapter 7

Lynn was reluctant, but he finally stumbled out his explanation. "It ain't like you, Doc. Comes from that Lobby woman you got. It's her dirty idea. We've seen the Lobby doctors cutting open our kids, poisoning their blood, and bleeding them dry. That ain't gonna happen again, Doc. You tell her it ain't!"

Doc swore as he realized their ignorance. An unexplained vaccination looked like poisoning of the blood. But he couldn't understand the bleeding part until Jake filled him in.

"Northport infant's wing. Each department has its own blood bank and donation is compulsory. Southport started it a couple months ago, too."

The long arm of the Lobby had reached out again. Now if he ever got them to try the treatment, it would be only after long sessions of preparing them with the facts, and there was hardly enough time for the crucial work!

By afternoon, Judge Ben Wilson reached them. His voice shook with fatigue as he climbed up to address the crowd through a power megaphone. "Southport's going crazy." He had to pause for breath between each sentence. "Earth's pulling back all the important people. They're packing them into the ships. They're leaving only colonials with no Earth rights. Those ships left when they decided the plague was coming from here. They won't let anybody back until the plague is licked. There won't be an Earth technician on Mars tomorrow."

"No bombs?" someone called.

"No bombs. The ships must have started before you rebelled, maybe meant honestly to save their own kind. But now it's a military action, and don't think it won't mean trouble. The poor devils in the city bet on the wrong horse. Now they can't run their food factories or anything else for long. Not without technicians. They've got to whip you now. Up to this time, they've been fighting for the Lobbies. Now they'll fight you for their own bellies to get your supplies. And they've still got shuttle rockets and fuel for them. Now beat it. I gotta confer with Jake."

Doc started after the judge, but Dr. Harkness caught his arm and drew him aside. Chris followed.

"I've found another epidemic," Harkness told them. "Over at Marconi. It's kept me on the run all night, and now half the village is down with it. Starts like a common cold, runs a fair fever, and the skin breaks out all over with bright red dots...."

He went on describing it. Chris began asking him about what medical supplies he had brought with him, pilfered from Northport hospital. She seemed to know what it was, but refused to say until she saw the cases. Doc also preferred to wait. Sometimes things weren't as bad as they seemed, though usually they were worse.

Marconi was dead to all outward appearances, with nobody on the streets. It had been a village of great hopes a week before, since this was where they had decided to experiment with switching the people back to Earth-normal. They'd had the best chance of survival of anyone on Mars until this came up.

Three people lay on the beds in the first house Harkness led them to. The room was darkened, and a man was stumbling around, trying to tend the others, though the little spots showed on his skin. He grinned weakly. "Hi, Doc. I guess we're making a lot of trouble, ain't we?"

Chris gave Doc no chance to answer. "Just as I thought. Measles! Plain old-fashioned measles."

"Figured so," the sick man said. "Like my brother back on Earth."

The others looked doubtful, but Doc reassured them. Chris should know; she'd worked in a swanky hospital where the patients were mostly Earth-normal. Measles was one of the diseases which was foiled by the metabolism switch. Well, at least they wouldn't have to be quarantined here.

Chris finished treating the family with impersonal efficiency, discussing the symptoms loudly with Harkness. "It's a good thing it isn't serious!"

"No," Harkness answered bitterly. "Not serious. It's only killed five children and three adults so far!"

"It would, here," Doc agreed unhappily. He led Chris out of the room on the pretext of washing his hands. "It's serious enough to force us to abandon the whole idea of going back to Earth-normal. Measles today, smallpox, tuberculosis, scarlet fever and everything else tomorrow. These people have lived Mars-normal so long their natural immunity has been destroyed. On Earth where the disease was everywhere, kids used to pick up some immunity with constant exposure, even without what might be called a case of the disease. Here, the blood has no reason to build antibodies. They can be killed by things people used to laugh at. How the disease got here, I don't know. But it's here. So we'll have to give up the idea of switching back to Earth-normal."

He gathered up one of the kits and started toward the other houses. "And Lord knows how long it will take to get the blood for the other treatment, even if it works."

They worked as a team for a while, with Harkness frowning as he watched Chris. Finally the young doctor stopped Chris outside the fifth house. "These are my patients, Dr. Ryan. I left the Lobby because I didn't believe colonials were mere livestock. I still feel the same. I appreciate your help in diagnosis and methods of treatment. But I can't let you handle my patients this way."

"Dan!" She swung around with eyes glazing. "Dan, are you going to stand for that?"

"I think you'd better wait in the tractor, Chris."

He was lucky enough to catch the kit she threw at him before its precious contents spilled. But it wasn't luck that guided his hand to the back of her skirt hard enough to leave it stinging.

Her face froze and she stormed out. A moment later they heard the tractor start off.

But Doc had no time to think of her. He and Harkness split up and began covering the streets, house by house, while he passed on the word to abandon the metabolism switch and go back to Mars-normal.

Jake sent two other doctors to relieve them late in the evening. Things were somewhat quieter at GHQ as Doc reported the events at Marconi.

"Where's Dr. Ryan?" Jake asked at last.

Doc exchanged glances with Harkness. "She isn't in the lab?"

"Wasn't there an hour ago."

Doc cursed himself for letting her go. With the knowledge that the radio in the mike was disabled, she'd obviously grabbed the first chance to report back. And with her had gone news of the only cure they had found.

Jake took it as philosophically as he could, though it was a heavy blow to his hopes. They spent half the night looking for her tractor, on the chance that she might have gotten lost or broken down, but there was no sign of it.

She was waiting in the laboratory when he returned at dawn. Her face was dirty and her uniform was a mess. But she was smiling. She got up to greet him, holding out two large bottles.

"Infant plasma--straight from Southport. And if you think I had it easy lying my way in and out of the hospital, you're a fool, Dan Feldman. If the man who took my place there hadn't been a native idiot, I never would have gotten away with it."

The things he had suspected could still be right, he realized. She could have reported everything to the Lobby. It was a better explanation than her vague account of bullying her way in and out. But she'd had a rough drive, and he wanted the plasma. Curiously, he was glad to have her back with him. He reached out a hand for the bottles.

She put the bottle on the table and grabbed up a short-bladed knife. "Not so fast," she cried. Her eyes were blazing now. "Dan Feldman, if you touch those bottles until you've crawled across the floor on your face and apologized for the way you treated me the last few days, I'll cut your damned heart out."

He shook his head, chuckling at the picture she made. There were times when he could almost see why he'd married her.

"All right, Chris," he gave in. "I'll be darned if I'll crawl, but you've earned an apology. Okay?"

She sighed uncertainly. Then she nodded and began changing for work.

XIV

Immunity

They worked through the day in what seemed to be armed truce. There was no coffee waiting for him when he awoke next, as he'd come to expect, but he didn't comment. He went to where she was already working, checking on the results of the plasma on the cultures.

The response had been slower than with the mouse blood, but now the bugs seemed to be dead. The filaments were destroyed, and there were no signs of the big cells. It seemed to be a cure, at least in the culture bottles.

"We'll need volunteers," he decided. "There should be animals, but we don't have any. At least this stuff isn't toxic. We need a natural immune and someone infected. Two of each, so one can be treated and the other used for a control. Makes four. Not enough to be sure, but it will have to do."

"Two," Chris corrected. "You're not infected, I am."

"Two others," he agreed. "I'll get them from Jake."

Most of GHQ was out on the street, but Doc found Jake inside the big schoolroom where he enjoyed his early morning bracky and coffee. The chief listened and agreed at once, turning to the others in the room.

"Who's had the jumping headache? Okay, Swanee. Who never had it?" He blinked in surprise as three men nodded out of the eight present. "I guess you go, Tom."

The two men stood up, tamping out their weeds, and went out with Doc.

Chris had everything set up. They matched coins to decide who would be treated. Doc noticed that Chris would get no plasma, while he was scheduled for everything. He watched her prepare the culture and add the accelerator that would speed development and make certain he and Tom were infected, then let her inject it.

That was all, except for the waiting. To keep conditions more closely alike, they were to stay there until the tests were finished, not even eating for fear of upsetting the conditions. Swanee dug out a pack of worn cards and began to deal while Doc dug out some large pills to use as chips.

It was an hour later when the pain began. Doc had just won the pot of fifty pills and opened his mouth for the expected gloating. He yelled as an explosion seemed to go off inside his head. Even closing his mouth was agony.

A moment later, Tom began to sweat. It got worse, spreading to the whole area of the back of the head and neck. Doc lay on the cot, envying Chris and Swanee who had already been infected naturally. He longed desperately for bracky, and had to keep reminding himself that no drugs must upset the tests. It was the longest day he had ever spent, and he began to doubt that he could get through it. He watched the little clock move from one minute to nine over to half a minute and hung breathless until it hit the nine. There was no question about whether the infection had taken. Now they could dull the agony.

Chris had the anodyne tablets already dissolved in water, and Swanee was passing out three lighted bracky weeds. It took a few minutes for the relief of the anodyne, and even that couldn't kill all the pain. But it didn't matter by comparison. He sucked the weed, mashed it out and began dealing the cards again.

They had a plentiful supply of the anodyne and used it liberally during the night. The test was a speeded-up simulation of the natural course of the disease, where painkiller would take time to get for most people here, but would then be used generously.

Precisely at nine in the morning, Chris began to inject Swanee and Doc with plasma.

Now there was no thought of cards. They waited, trying to talk, but with most of their attention on the clock. Doc had estimated that an hour should be enough to show results, but it was hard to remember that an hour was the guess as to the minimum time.

He winced as Chris took a tiny bit of flesh from his neck. She went to the other men, and then submitted to his work on herself. Then she began preparing the slides.

"Feldman," she read the name of the slide as she inserted it into the microscope. Then her breath caught sharply. "Only dead cells!"

It was the same for Swanee and Tom. Each had to look at his own slide and have it explained before the results could be believed. But at last Chris bent over her own slide. A minute later she glanced up, nodding. "What it should be. It checks."

Tom whooped and went out the door to notify Jake. There was only plasma for some two hundred injections, but that should yield sufficient proof. Once salvation was offered, there should be no trouble convincing the people that blood donations from their children were worthwhile.

Later, when the last of the plasma had been used, they could finally relax. Chris slipped off her smock and dropped onto the cot. A tired smile came onto her lips. "You're forgiven, Dan," she said. A moment later she was obviously asleep. Doc meant to join her, but it was too much effort. He leaned his head forward onto his arms, vaguely wondering why she was calling off the feud.

It was night outside when he awoke, and he was lying on the cot, though he still felt cramped and strained. He stirred, groaning, and finally realized that a hand was on his shoulder shaking him. He looked up to see Jake above him. Chris was busy with the coffee maker.

Jake slumped onto the cot beside Doc. "We took Southport," he announced.

That knocked the sleep out of Doc's system. "You what?"

"We took it, lock, stock and barrel. I figured the news of your cure would put guts into the men, and it did. But we'd probably have taken it anyhow. There wasn't anything to fight for there after Earth pulled out and the plague really hit. Wilson mistook last-minute panic for fighting spirit. The poor devils didn't have anything to fight about, once the Lobby stopped goading them."

Doc tried to assimilate the news. But once the surprise was gone, he found it meant very little. Maybe his revolutionary zeal had cooled, once the Lobby men had pulled out. "We'll need a lot more plasma than there is in Southport," he said.

"Not so much, maybe," Jake denied. "Doc, three of the men you injected were shot down as runners. Your plasma's no good."

"It takes time to work, Jake. I told you there might be a case or two that would be too close to the edge. Three is more than I expected; but it's not impossible."

"There was plenty of time. They blew after we got back from Southport." Jack dropped his hand on Doc's shoulder, and his face softened. "Harkness tested every man you injected. He finished half an hour ago. Five showed dead bugs. The rest of them weren't helped at all."

Doc fumbled for a weed, trying to think. But his thoughts refused to focus. "Five!"

"Five out of two hundred. That's about average. And what about Tom? He was jumping around after the test last night, telling how you'd cured him, how he'd seen the dead bugs; but he never had the jumping headache, and you never gave him the plasma! He's got dead bugs, though. Harkness tested him."

Doc let his realization of his own idiocy sink in until he could believe it. Jake was right. Tom had never been treated, yet Chris had reported dead bugs. They'd all been so ready to believe in miracles that no one had been able to think straight after the long wait.

"There was a bump on his neck--a small one," he said slowly. "Jake, he must have caught it, even if he seemed immune. If he was taking anodyne anyway for something--or unconscious--"

"He was up in Northport six years ago for a kidney operation," Jake admitted doubtfully. "We had to chip in to pay for it. But you still didn't treat him, and he's cured. Face it, Doc, that plasma is no good inside the body."

His hand tightened on Doc's shoulder again. "We're not blaming you. We don't judge a man here except by what he is. Maybe the stuff helps a little. We'll go on using it when we get it; tell everybody you were a mite optimistic, so they'll figure it's a gamble, but have a little hope left. And you keep trying. Something cured it in Tom. Now you find out what."

Doc watched him go out numbly, and turned to Chris.

"It can't be right," she said shakily. "You and Swanee were cured. Maybe it was the accelerator. It had to be something."

"You didn't have the accelerator," he accused.

"No, and I've still got live bugs. I was never supposed to be cured, so I expected to see just what I saw. How I missed the fact that Tom should have been like me, I don't know. Damn it, oh, damn it!"

He's never seen her cry before, except in fury. But she mastered it almost at once, shaking tears out of her eyes. "All right. Plasma works in a bottle but not in an adult body. Maybe something works in the body but not in a bottle."

"Maybe. And maybe some people are just naturally immune after it reaches a certain stage. Maybe we ran into coincidence."

But he didn't believe that, any more than she did. The answer had to be in the room. He'd taken a massive dose of the disease and been cured in a few hours.

Outside the room, the war went on, drawing toward a close. The supposed partial cure was good propaganda, if nothing else, and Jake was widening his territory steadily. There was only token resistance against him. He had the Southport shuttles now to cover huge areas in a hurry. But inside the room, the battle was less successful. It wasn't the accelerator. It wasn't the tablets of anodyne. They even tried sweeping the floor and using the dust without results.

Then another test in the room, made with four volunteers Jake selected, yielded complete cures after injections with plain salt water in place of plasma.

The plague speeded up again. About four people out of a hundred now seemed to have caught the disease and cured themselves. They accounted for what faith was left in Doc's plasma and gave some unfounded hope to the others.

Northport fell a week later, putting the whole planet in rebel hands.

Jake returned, wearier than ever. He'd proved to be one of the natural immunes, but the weight of the campaign that could only end in a defeat by the plague left him no room to rejoice in his personal fortune.

This time he looked completely defeated. And a moment later, Doc saw why as Jake flipped a flimsy sheet onto the table. It bore the seals of Space and Medical Lobbies.

Jake pointed upwards. "The war rockets are there, all right. We knew they'd come. Now all they want for calling them off is our surrender and your cure. If they don't get both, they'll blow the planet to bits. We have two days."

The rockets could be seen clearly with binoculars. There were more than enough to destroy all life on the planet. Maybe they'd be used eventually, anyhow, since the Lobbies wanted no more rebellion. But with a cure for the plague, he might have bought them off.

Chris stood beside him, looking as if it were a bitter pill for her, too. She'd risked herself in the hands of the enemy, had cooperated with him in everything she'd been taught to oppose, and had worked like a dog. Now the Lobbies seemed to forget her as a useless tool. They were falling back on a raw power play and forgetting any earlier schemes.

"Maybe they'd hold off for a while if I agreed to go to them and share all my ideas, specimens and notes," he said at last. "Do you think your Lobby would settle for that, Chris?"

"I don't know, Dan. I've stopped thinking their way." She seemed almost apologetic for the admission.

He dropped an arm over her shoulder and turned with her back to the laboratory. "Okay, then we've got to find a miracle. We've got two days ahead of us. At least we can try."

But he knew he was lying to himself. There wasn't anything he could think of to try.

XV

Decision

Two days was never enough time for a miracle. Doc decided as he packed his notes into a small bag and put it beside his bundle of personal belongings. He glanced around the room for the last time, and managed a grin at Jake's gloomy expression.

"Maybe I can bluff them, or maybe they'll string along for a while," he said. "Anyhow, now that they've agreed to take me and my notes in place of the cure we're fresh out of, I've got to be on that shuttle when it goes back to their men at orbital station."

Jake nodded. "I don't like selling friends down the river, Doc. But it wouldn't do you any more good to blow up with the planet, I reckon. They won't call off the war rockets when they do get you, of course. But maybe they won't use them, except as a threat to put the Lobbies back in, stronger than ever."

He stuck out one of his awkwardly shaped hands, clapped the aspirator over his face and hurried out. Doc picked up his bags and went toward the little tractor where Lou was waiting to drive him and Chris back toward Southport and the shuttle rocket that would be landing for them. They hadn't mentioned Chris in their demands, but her father must expect her to return.

After they had him, he'd be on his own. His best course was probably to insist on talking only to Ryan at Medical Lobby, and then being completely honest. The room here would be kept sealed, in case the Lobby wanted to investigate where he had failed. And his notes were honest, which was something that could usually be determined. Chris could testify to that, anyhow, since she'd kept a lot of them for him.

At best, there would be a chance for some compromise and perhaps some clue for them that might eventually end the plague. They had enough men to work on it, and billions in equipment. At worst, he should gain a little time.

"Cheer up, Chris," he told her as he climbed through the little airlock. "Maybe Harkness will turn up the cure before our negotiations break down. He has the whole of Northport Hospital to play with. They haven't tried to chase him out of there yet. After all, we almost found something with no equipment except wild imaginations."

She shook her head as the tractor began moving. "Shut up! I've got enough trouble without your coming down with logorrhea. Don't be a fool."

"Why change now?" he asked her. "Everything I've done has been because I am a fool. I guess my luck lasted longer than I could expect. And I'm still fool enough to think that the solution has to turn up eventually. We know it has to be in that room. Damn it, we must know it--if we could only think straight now."

She reached over and touched his hand, but made no comment. They had been over that statement of desperation too many times already. But it kept nagging at him--something in the room, something in the room! Something so common that nobody noticed it!

They passed a crowd chasing down a runner. Something in that room could have saved the unlucky man. It could have saved Mars, perhaps.

He growled for the hundredth time, cursing his fatigue-numbed mind. Too little sleep, too much coffee and bracky....

He reached for the package of weed, realizing that he would miss it on Earth, if he ever got there. Like everything here on the planet, he'd begun by detesting it and wound up finding it the thing he wanted to keep forever. He lighted the bracky and sat smoking, watching Lou drive. When the first was finished, he lighted another from the butt.

She put out a hand and took it away. "Please, Dan. I can stand the stuff, but I'll never like it, and the tractor's stuffy enough already. I've taken enough of it. And it keeps reminding me of our test--the three of you stinking up the place, puffing and blowing that out, while I couldn't even get a breath of air...."

She was getting logorrhea herself now and--

The answer finally hit him! He jerked around, making a grab for Lou's shoulder, motioning for the man to head back.

"Bracky--it has to be! Chris, that's it. Jake picked out the second group of men from his friends--and they are all cronies because they hang around so much in their so-called smoking room. The first time, it killed the bugs for all of us who smoked--and it didn't work for you because you never learned the habit."

Lou had the tractor turned and the rheostat all the way to the floor.
