Red Doctor Sam Jenkins took one look at the Ten minutes later the Red Doctor reached for the results of the Initial doctors and spells." He tossed the Info-card down the chute with a The surgeon in the green undershorts chewed his lip. "Looks like "And spend the next twenty years scrubbing test tubes." Jenkins shook It had always been that way. Since the first formal Medical Service stone: immediate medical assistance, without question or hesitation, landed, the crew was soon rendering Medical Services of one sort or the Medical Service Contract was formalized, and Hospital Earth came they came across. Serious problems were shuttled back to Hospital Earth surgery—were able to handle the problems on the spot and by themselves. triangled her in, grappled her, and dropped her with a bone-jarring crash into a landing slot on the edge of the city. As Sam Jenkins and speed?" Jenkins twisted down the volume on his Translator with a grimace. The Red Doctor blinked at his companion, then turned to Aguar. "What They walked to the bedside and lifted back the covers. Jenkins took a loosely from his arm. Doc." "Probably a viremia of some sort." Jenkins went over the great groaning hulk with inquiring fingers. "If it's a viremia, we're cooked," Stone whispered. "None of the drugs cross over—and we won't have time to culture the stuff and grow any new ones—" "What about your own doctors?" tightly. "Sure, sure," he said weakly. "You just watch us." "But what do you think we're going to do?" the surgeon wailed, back antibiotic was more deadly to the race than the virus was...." "Might not be such a bad idea for Morua," the Red Doctor muttered have our throats slit right on the spot?" He grabbed a pad and began "Well, we've got a little to go on just from looking at them. They're oxygen-breathers, which means they manage internal combustion of carbohydrates, somehow. From the grey skin color I'd guess at a cuprous or stannous heme-protein carrying system. They're carnivores, but god knows what their protein metabolism is like—Let's get going on some of these specimens Aguar has rounded up for us." doctor from Sol III. Anatomy was a broad determinant: a jelly-blob from Deneb I with its fine skein of pulsating nerve fibrils was still just a jelly-blob, and would never rise above the level of amoeboid yes-no response because of its utter lack of organization. But a creature took about six months to do— ran the X-ray and pan-endoscopic examinations. After four grueling hours the Red Doctor groaned and scowled at the growing pile of data. control room at gunpoint, along with a couple of minor medical the Red Doctor cut him off. "It for a long moment. Then: "You're an idiot. It can't be done." "Suppose it could." "The Spirit of the Pox is too strong. Our most powerful spells make him laugh. He eats our powders and drinks our potions. Even the Iron Circle won't drive him out." "Won't it, now! Well, we have iron needles and potions that eat the bottoms out of their jars. Suppose The whispers stopped and Kiz nodded to the Red Doctor. "All right, we "I'll be in the sickroom in a very short while. If you're with me, I'll As soon as they had gone Jenkins dived into the storeroom and began promises, pills and post-mortems. That's the Medical service for you." "No thanks, not me. This is a medical case and it's all yours. What do poke holes in the healthy ones! And then you send in and laid them on a bench, then set his black bag carefully on the floor to the braziers at the bedside. "They're enough to give anybody a headache. And tell those people outside to stop the racket. How can they expect the Spirit of the Pox to come out of His Eminence when they're raising a din like that?" As he talked Jenkins dug into the black bag and started assembling a liter flask, tubing and needles. "First we brewed witches' root for seven hours and poured it over his belly. When the Pox appeared in spite of this we lit three red candles and drink—" The wizard broke off to stare at the bottle-and-tube arrangement Jenkins had prepared. "What's that?" "I told you about the iron needles, didn't I? Hold this a moment." Jenkins handed him the liter flask. "Hold it high." He began searching flowed back greenishly in the tube for an instant as he placed the needle then the flask began to drip slowly. Jenkins held up his hand for silence. He allowed the first intravenous flask to pour in rapidly the second he adjusted to a steady drip-drip-drip. Next he pulled two large bunsen burners and a gas tank from the bag. above it into this he poured some water and a few crystals from a dark bottle. In a moment the fluid in the flask was churning and boiling, an ominous purple color. Kiz watched goggle-eyed. "Now!" said Jenkins, pulling out a long thin rubber tube. "This should annoy the Spirit of the Pox something fierce." He popped the tube into the patient's mouth. His Eminence rose up with a gasp, choking and fighting, but the tube went down. The Red Doctor ground three white pills into powder, mixed in some water, and poured it down the tube. Then he stepped back to view the scene, wiping cold perspiration from "Fine. Now this is most important." Jenkins searched in the bag until rhythm with the intravenous drip ... and waited. The room was deathly still except for a heavy snuffling sound from His Eminence and the plink-plink of the pestle on the mortar. The flask of Jenkins motioned to Kiz. "His pulse—quickly!" Jenkins' face darkened. He peered at the sick man intently. "It's a Without breaking the rhythm he transferred the plinking-job to Kiz. He changed the dwindling intravenous bottle. "Call me when the bottle is empty—or if there is any change. Whatever you do, don't touch They woke him once, hours later, to change the intravenous solution, administered more of the white powder in water down the tube, and went back to his bench. He had barely fallen asleep again when they were glistening in the light of the bunsen burners. He rolled from side to side, groaning hoarsely. " Faster! mortar, and began stripping off the sodden bedclothes. "Blankets, monumental groan and buried his head in the blankets. In two minutes through to somebody at HQ," he said as the Red Doctor climbed aboard. "It'll take them twenty days at least, to get help, considering that "With what? Incantations?" expected them, obviously, since that was the only level of medicine Bio-survey we were hamstrung. But whatever the Pox is, it obviously involves fever, starvation and dehydration. I knew that His Eminence could assimilate carbohydrates, and I took a long gamble that an antipyretic wouldn't hurt him too much—" Wally Stone's jaw sagged. "So you treated him with sugar-water and aspirin," he said weakly. "And on that you risked our necks." "Not quite," said the Red Doctor. "You're forgetting that I had one other prescription to use—the oldest, most trustworthy up her little black bag and go home."
