Peter's eyes were dull, his limbs slumped. For a moment I thought that arrangement: I did what Peter wished, so long as I did not actively Peter called an emotion than they were. I did not even wish that Peter were not dead, for A tear was trickling down my cheek. Young Peter Karson put the last black-print down and sighed with satisfaction. His dream was perfect the A discordant note suddenly entered his fantasy. He looked up, conscious terrible illusion. INVADERS APPEAR IN BOSTON. 200 DEAD "The reason for this ... order must be apparent to all civilized peoples. For the Invaders have spared no part of this planet in their and this is more intolerable than any normal invasion. "I have no fear that the people of Earth will fail to meet this challenge, for there is no alternative. Not only our individual lives are threatened, but our existence as a race. We must, and will, destroy the Invaders!" Peter sank back in his chair, the full shock of it striking him for the "What makes, Peter my love?" she asked, and bent back to the ledger. horrible than any cry of agony. "The Invaders are here, citizens," the commentator was saying in a strangled voice. "Stay off the streets. Hide yourselves. Stay off the Lorelei buried her head on his chest, clutching at him desperately. "Peter!" she said faintly. "Why do they broadcast such things?" "They have to," he told her grimly. "There will be panics and suicides, and they know it but they have to do it. This isn't like a war, where the noncombatants' morale has to be kept up. There aren't going to be any noncombatants, this time. Everybody in the world has to know about them, so that he can fight them—and then it may not be enough." Peter's lips were cold with sweat. Tiny nerves in his face and arms Peter! range of vision. Peter forced himself forward another step. Little Harry Kanin, Lorelei's assistant, was crumpled in a corner, half supported by the broad base of an X-ray chamber. His face was flaccid and bloated. His In a moment Peter realized what they were doing to him. He stood, but there was a tiny sound in Peter's brain, a thin, dry whispering. "You're in a hospital. Just lie quietly, please." He tried to get up again. "Where's Lorelei?" Peter sank back in the bed. The room was coming into focus. He looked the nurse bent over him with a glass half full of milky fluid. It tasted awful, but she made him drink it all. He was right. All the nurses, and even Dr. Arnold, were evasive, but he kept asking them why he couldn't see Lorelei, and finally he wormed it out of them. It had been nine and a half months, not three, and he'd been in a coma all that time. Lorelei, it seemed, had recovered much sooner. "She was only suffering from ordinary shock," Arnold explained. for approximately five minutes. Yes, we know—you talked a lot. It's a miracle you're alive, and rational." "But where is she?" Peter complained. "You still haven't explained why I haven't been able to see her." Arnold frowned. "All right," he said. "I guess you're strong enough to take it. She's underground, with the rest of the women and children, and a good two-thirds of the male population. That's where you'll go, "But why?" Peter whispered. Arnold's strong jaw knotted. "We're hiding," he said. "Everything else Peter couldn't think of anything to say. Dr. Arnold's voice went on "And since then?" Peter asked huskily. an impossible task if we tried to include all the thinly-populated areas, of course, but it doesn't matter. By the time we excavate enough to take care of a quarter of the earth's population, the other three-quarters will be dead, or worse." "I wonder," Peter said shakily, "if I am strong enough to take it." Arnold laughed harshly. "You are. You've got to be. You're part of our last hope, you see." "Our last hope?" "I see," said Peter. And for the first time, he thought of the thousand. It wouldn't house a hundred scientists, eagerly delving into the hinterland of research. The huge compartments weren't filled with instead, there was compressed oxygen there, and concentrated food, enough to last a lifetime. It was a new world, all by itself or else it was a tomb. And there was Lorelei said, "You can't do it. I won't let you! Peter—" "Darling," he began wearily. "Don't throw your life away! Give us time—there must be another way." "There's no other way," Peter said. He gripped her arms tightly, as if he could compel her to understand by the sheer pressure of his fingers. They still come down here, only not as many. The mortality rate is up, the suicide rate is up, the birth we're riding a curve that ends in extinction fifty years from now. "They'll live, and we'll die, because they're a superior race. We're a million years too far back even to understand what they are or where they came from. Besides them, we're apes. There's only one answer." or twelve toes, or a dozen ears—or a better brain. Out of those millions of possible mutations, there's one that will save the human race. We can't fight them , but a superman could. That's our only chance. Lorelei—darling—don't you see that?" She choked, "But why can't you take me along?" He stared unseeingly past her wet, upturned face. "You know why," he said bitterly. "Those rays are strong. They don't only work on embryos they change adult life forms, too. I have one chance in seven of staying alive. You'd have one chance in a million of staying beautiful. I couldn't stand that. I'd kill myself, and then humanity would die, too. You'd be their murderer." Her sobs gradually died away. She straightened slowly until he no longer had to support her, but all the vitality and resilience was gone out of her body. "All right," she said in a lifeless voice. "You'll come back, Peter." The Avenger its slow, monstrous alchemy upon him. Peter waited until the changes from the incubators. Time went by, meaninglessly. He ate when he was hungry, slept when his driving purpose let him, and worked unceasingly, searching for the million-to-one chance. He stared sometimes through changed eyes at the tiny blue star that was Earth, wondering if the race he had left behind still burrowed in its after a time he ceased even to wonder. And one changeling-child he did not destroy. He fed knowledge to its eager brain, and watched it through the swift years, with a dawning hope.... Peter closed the diary. "The rest you know, Robert," he said. "Yes," I told him. "I was that child. I am the millionth mutation you were searching for." you, not telling you, even, about Earth until now—because I had to be sure. But now, the waiting is over. "They're still there, I'm sure of it—the people, and the Invaders. You can kill the Invaders, Robert." He looked at me, a little oddly, almost as if he had some instinctive knowledge of what was to come. But he went on swiftly, "On Earth we
