СКАЧАТЬ against the virus while he was infected. Remember, he doesn’t have a rigid body structure like we do. He’s mostly just basic protein, and he can synthesize pretty much anything he wants to or needs to.”

      Jack blinked. “It’s an idea, at least. Is there any way we can get some of his body fluid away from him? Without getting bit, I mean?”

      “No problem there,” Dal said. “He can regenerate pretty fast if he has enough of the right kind of food. He won’t miss an ounce or two of excess tissue.”

      He took a beaker over to Fuzzy’s platform and began squeezing off a little blob of pink material. Fuzzy seemed to sense what Dal wanted; obligingly he thrust out a little pseudopod which Dal pinched off into the beaker. With the addition of a small amount of saline solution, the tissue dissolved into thin, pink suspension.

      In the laboratory they found two or three of the guinea pigs in the last stages of the infection, and injected them with a tiny bit of the pink solution. The effect was almost unbelievable. Within twenty minutes all of the injected animals began to perk up, their eyes brighter, nibbling at the food in their cages, while the ones that had not been injected got sicker and sicker.

      “Well, there’s our answer,” Jack said eagerly. “If we can get some of this stuff injected into our friends down below, we may be able to protect the healthy ones from getting the plague, and cure the sick ones as well. If we still have enough time, that is.”

      They had landing permission from the Bruckian spokesman within minutes, and an hour later the Lancet made an orderly landing on a newly-repaved landing field near one of the central cities on the seventh planet of 31 Brucker.

      Tiger and Jack had obviously not exaggerated the strange appearance of the towns and cities on this plague-ridden planet, and Dal was appalled at the ravages of the disease that they had come to fight. Only one out of ten of the Bruckians was still uninfected, and another three out of the ten were clearly in the late stages of the disease, walking about blankly and blindly, stumbling into things in their paths, falling to the ground and lying mute and helpless until death came to release them. Under the glaring red sun, weary parties of stretcher bearers went about the silent streets, moving their grim cargo out to the mass graves at the edge of the city.

      The original spokesman who had come up to the Lancet was dead, but another had taken his place as negotiator with the doctors—an older, thinner Bruckian who looked as if he carried the total burden of his people on his shoulders. He greeted them eagerly at the landing field. “You have found a solution!” he cried. “You have found a way to turn the tide—but hurry! Every moment now is precious.”

      During the landing procedures, Dal had worked to prepare enough of the precious antibody suspension, with Fuzzy’s co-operation, to handle a large number of inoculations. By the time the ship touched down he had a dozen flasks and several hundred syringes ready. Hundreds of the unafflicted people were crowding around the ship, staring in open wonder as Dal, Jack and Tiger came down the ladder and went into close conference with the spokesman.

      It took some time to explain to the spokesman why they could not begin then and there with the mass inoculations against the plague. First, they needed test cases, in order to make certain that what they thought would work in theory actually produced the desired results. Controls were needed, to be certain that the antibody suspension alone was bringing about the changes seen and not something else. At last, orders went out from the spokesman. Two hundred uninfected Bruckians were admitted to a large roped-off area near the ship, and another two hundred in late stages of the disease were led stumbling into another closed area. Preliminary skin-tests of the antibody suspension showed no sign of untoward reaction. Dal began filling syringes while Tiger and Jack started inoculating the two groups.

      “If it works with these cases, it will be simple to immunize the whole population,” Tiger said. “From the amounts we used on the guinea pigs, it looks as if only tiny amounts are needed. We may even be able to train the Bruckians to give the injections themselves.”

      “And if it works we ought to have a brand new medical service contract ready for signature with Hospital Earth,” Jack added eagerly. “It won’t be long before we have those Stars, you wait and see! If we can only get this done fast enough.”

      They worked feverishly, particularly with the group of terminal cases. Many were dying even as the shots were being given, while the first symptoms of the disease were appearing in some of the unafflicted ones. Swiftly Tiger and Jack went from patient to patient while Dal kept check of the names, numbers and locations of those that were inoculated.

      And even before they were finished with the inoculations, it was apparent that they were taking effect. Not one of the infected patients died after inoculation was completed. The series took three hours, and by the time the four hundred doses were administered, one thing seemed certain: that the antibody was checking the deadly march of the disease in some way.

      The Bruckian spokesman was so excited he could hardly contain himself; he wanted to start bringing in the rest of the population at once. “We’ve almost exhausted this first batch of the material,” Dal told him. “We will have to prepare more—but we will waste time trying to move a whole planet’s population here. Get a dozen aircraft ready, and a dozen healthy, intelligent workers to help us. We can show them how to use the material, and let them go out to the other population centers all at once.”

      Back aboard the ship they started preparing a larger quantity of the antibody suspension. Fuzzy had regenerated back to normal weight again, and much to Dal’s delight had been splitting off small segments of pink protoplasm in a circle all around him, as though anticipating further demands on his resources. A quick test-run showed that the antibody was also being regenerated. Fuzzy was voraciously hungry, but the material in the second batch was still as powerful as in the first.

      The doctors were almost ready to go back down, loaded with enough inoculum and syringes to equip themselves and a dozen field workers when Jack suddenly stopped what he was doing and cocked an ear toward the entrance lock.

      “What’s wrong?” Dal said.

      “Listen a minute.”

      They stopped to listen. “I don’t hear anything,” Tiger said.

      Jack nodded. “I know. That’s what I mean. They were hollering their heads off when we came back aboard. Why so quiet now?”

      He crossed over to the viewscreen scanning the field below, and flipped on the switch. For a moment he just stared. Then he said: “Come here a minute. I don’t like the looks of this at all.”

      Dal and Tiger crowded up to the screen. “What’s the matter?” Tiger said. “I don’t see ... wait a minute!”

      “Yes, you’d better look again,” Jack said. “What do you think, Dal?”

      “We’d better get down there fast,” Dal said, “and see what’s going on. It looks to me like we’ve got a tiger by the tail....”

      *

      They climbed down the ladder once again, with the antibody flasks and sterile syringes strapped to their backs. But this time the greeting was different from before.

      The Bruckian spokesman and the others who had not yet been inoculated drew back from them in terror as they stepped to the ground. Before, the people on the field had crowded in eagerly around the ship; now they were standing in silent groups staring at the doctors fearfully and muttering among themselves.
