R X Ten minutes later the Red Doctor reached for the results of the Initial Information Survey on Morua II, and let out a howl of alarm. A single something." A moment later a tall sleepy man in green undershorts appeared at this ?" growl. "So now we have an emergency call from them in a Contract code they couldn't possibly know." there, are we?" "What else? You know the law. Instantaneous response to any crash-priority call, regardless of circumstances—" "Law be damned," Stone cried. "File a protest with HQ. Cancel the If we still happen to be around later, that is." It had always been that way. Since the first formal Medical Service Contract had been signed with Deneb III centuries before, Hospital Earth had laboriously built its reputation on that single foundation stone: immediate medical assistance, without question or hesitation, whenever and wherever it was required, on any planet bound by Contract. but in any growing civilization division of labor inevitably occurs. The Lancet crash into a landing slot on the edge of the city. As Sam Jenkins and Wally Stone picked themselves off the bulkheads, trying to rearrange the scarlet and green uniforms of their respective services, the main entrance lock burst open with a squeal of tortured metal. At least a with heavy grey fur ruffing out around their faces like thick hairy dog collars. The one in command strode forward arrogantly, one huge paw leveling a placer-gun with a distinct air of business about it. "Well, you took long enough!" he roared, baring a set of yellow fangs government. Finally a pair of steel doors opened to admit them to a long, arched hallway. Their leader, who was called Aguar by his he wore a long purple cap with a gold ball on the end which twitched wildly as their whispered conference devolved into growling and snarling. Finally "What about your own doctors?" gave them a terrible grin and tightened his hand on the gold-encrusted sword. "Now we see." . "Sam, we can't touch him. If without a Bio-survey—look what happened on Baron when they tried it! Half the planetary population wiped out before they realized that the grimly. "Well, what did you expect me to do—politely refuse? And have our throats slit right on the spot?" He grabbed a pad and began scribbling. "We've got to do something just to keep alive for a while." "Well, we've got a little to go on just from looking at them.

Certain basic principles were always the same, a fact which accelerated the program considerably. Humanoid or not, all forms of life had basic response because of its utter lack of organization. But a creature with an organized central nervous system and a functional division of no major setbacks, and full cooperation of the natives, the job only took about six months to do— For the crew of the Lancet handled external examinations and blood and tissue chemistries Stone ran the X-ray and pan-endoscopic examinations. After four grueling hours the Red Doctor groaned and scowled at the growing pile of data. "Okay. It seems that they're vaguely humanoid. And that's about all we Silence. "All right then, what causes it? Do you know? Bacteria? Virus? Degeneration?" Silence. the Red Doctor cut him off. "It Kiz stopped sputtering quite abruptly. He blinked at his confederates for a long moment. Then: "You're an idiot. It can't be done." "Suppose it could." "Won't it, now! Well, we have iron needles bargain," he said. " After promises, pills and post-mortems. That's the Medical service for you." That would open their eyes all right." grimly. "Tell them to send an armada, because we're liable to need one in the next few hours—" this bag of cure the Boss here." Solemnly he slipped off his scarlet tunic and cap and laid them on a bench, then set his black bag carefully on the floor and threw it open. "First off, get rid of those things." He pointed to the braziers at the bedside. "They're enough to give anybody a then he threw open the door and screamed a command. The wailing stopped as though a switch had been thrown. As a couple of cowering guards crept in to remove the "Tell me what spells you've already used." "First we brewed witches' root for seven hours and poured it over his at the foot of the bed and beat His Eminence steadily for one hour out of four, with new rawhide. When His Eminence protested this, we were certain the Spirit had possessed him, so we beat him one hour out of two—" Jenkins winced as the accounting of cabalistic clap-trap continued. His Eminence, he reflected, must have had the constitution of an ox. He "I told you about the iron needles, didn't I? Hold this a moment." in a moment he was back with a detachment of guards, all armed to the teeth, and the second he adjusted to a steady drip-drip-drip. Next he pulled two large bunsen burners and a gas tank from the bag. 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. he found a large mortar which he set down on the floor. Squatting behind it, he began tapping it slowly with the pestle, in perfect rhythm with the intravenous drip ... and waited. Jenkins motioned to Kiz. "His pulse—quickly!" Kiz scampered gratefully over to the bedside. "A hundred and eighty," he whispered. He changed the dwindling intravenous bottle. "Call me when the bottle anything ." With that he tiptoed from the room. Four murderous-looking guards down on a bench in the hall and fell asleep in an instant. They woke him once, hours later, to change the intravenous solution, administered more of the white powder in water down the tube, and went patient's vital signs, wiped more sweat from his furry brow. Quite suddenly His Eminence opened bleary eyes, stared about him, let out a monumental groan and buried his head in the blankets. In two minutes , where Wally Stone stared in disbelief as Jenkins and Kiz bowed and hugged each other like long-lost brothers at a sad farewell. "I finally got "It'll take them twenty days at least, to get help, considering that first place, but that's the best they can do...." "Tell them to forget the armada," said Jenkins, grinning. "And anyway, they've got things all wrong back at HQ." He brandished a huge roll the Contract in the dry-storage locker with a sigh. "Old Kiz just finished his first lesson, and he's still wondering what went on—" "So am I," said the Green Doctor suspiciously. "It was simple. We cured His Eminence of the Pox." "With what? Incantations?" "Oh, the incantations were for the ," said Jenkins. "They expected them, obviously, since that was the only level of medicine 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 healer-of-all-ills known to medicine, just as potent now as it was a
