"You'll have to keep this crowd under control," Dal said to the spokesman. "We're going to take this one aboard the ship and examine him to see what this reaction could be, but this mob is beginning to sound dangerous." "They're afraid," the spokesman said. "They want to know what you've done to them, what this new curse is that you bring in your syringes." "It's not a curse, but something has gone wrong. We need to learn what, in order to deal with it." "The people are afraid and angry," the spokesman said. "I don't know how long I can control them." And indeed, the attitude of the crowd around the ship was very strange. They were not just fearful; they were terrified. As the doctors walked back to the ship leading the stricken Bruckian behind them, the people shrank back with dreadful cries, holding up their hands as if to ward off some monstrous evil. Before, in the worst throes of the plague, there had been no sign of this kind of reaction. The people had seemed apathetic and miserable, resigned hopelessly to their fate, but now they were reacting in abject terror. It almost seemed that they were more afraid of these walking shells of their former selves than they were of the disease itself. But as the doctors started up the ladder toward the entrance lock the crowd surged in toward them with fists raised in anger. "We'd better get help, and fast," Jack said as he slammed the entrance lock closed behind them. "I don't like the looks of this a bit. Dal, we'd better see what we can learn from this poor creature here." As Tiger headed for the earphones, Dal and Jack went to work once again, checking the blood and other body fluids from the stricken Bruckian. But now, incredibly, the results of their tests were quite different from those they had obtained before. The blood sugar and protein determinations fell into the pattern they had originally expected for a creature of this type. Even more surprising, the level of the antibody against the plague virus was high--far higher than it could have been from the tiny amount that was injected into the creature. "They must have been making it themselves," Dal said, "and our inoculation was just the straw that broke the camel's back. All of those people must have been on the brink of symptoms of the infection, and all we did was add to the natural defenses they were already making." "Then why did the symptoms appear?" Jack said. "If that's true, we should have been _helping_ them, and look at them now!" Tiger appeared at the door, scowling. "We've got real trouble, now," he said. "I can't get through to a hospital ship. In fact, I can't get a message out at all. These people are jamming our radios." "But why?" Dal said. "I don't know, but take a look outside there."
