Platinum Pohl - The Collected Best Stories

by Frederik Pohl

  A Western human being—comfortably pudgy on a diet of twenty-eight hundred calories a day, resolutely jogging to keep the flab away or mournfully conscience-stricken at the thickening thighs and the waistbands that won’t quite close—can survive for forty-five days without food. By then the fat is gone. Protein reabsorptions of the muscles is well along. The plump housewife or businessman is a starving scarecrow. Still, even then care and nursing can still restore health.

  Then it gets worse.

  Dissolution attacks the nervous system. Blindness begins. The flesh of the gums recedes, and the teeth fall out. Apathy becomes pain, then agony, then coma.

  Then death. Death for almost every person on Earth…

  For forty days and forty nights the rain fell, and so did the temperature. Iceland froze over.

  To Harry Malibert’s astonishment and dawning relief, Iceland was well equipped to do that. It was one of the few places on Earth that could be submerged in snow and ice and still survive.

  There is a ridge of volcanoes that goes almost around the Earth. The part that lies between America and Europe is called the Mid-Atlantic Ridge, and most of it is under water. Here and there, like boils erupting along a forearm, volcanic islands poke up above the surface. Iceland is one of them. It was because Iceland was volcanic that it could survive when most places died of freezing, but it was also because it had been cold in the first place.

  The survival authorities put Malibert to work as soon as they found out who he was. There was no job opening for a radio astronomer interested in contacting far-off (and very likely nonexistent) alien races. There was, however, plenty of work for persons with scientific training, especially if they had the engineering skills of a man who had run Arecibo for two years. When Malibert was not nursing Timothy Clary through the slow and silent convalescence from his pneumonia, he was calculating heat losses and pumping rates for the piped geothermal water.

  Iceland filled itself with enclosed space. It heated the spaces with water from the boiling underground springs.

  Of heat it had plenty. Getting the heat from the geyser fields to the enclosed spaces was harder. The hot water was as hot as ever, since it did not depend at all on sunlight for its calories, but it took a lot more of it to keep out a -30°C chill than a +5°C one. It wasn’t just to keep the surviving people warm that they needed energy. It was to grow food.

  Iceland had always had a lot of geothermal greenhouses. The flowering ornamentals were ripped out and food plants put in their place. There was no sunlight to make the vegetables and grains grow, so the geothermal power-generating plants were put on max output. Solar-spectrum incandescents flooded the trays with photons. Not just in the old greenhouses. Gymnasia, churches, schools—they all began to grow food under the glaring lights. There was other food, too, metric tons of protein baaing and starving in the hills. The herds of sheep were captured and slaughtered and dressed—and put outside again, to freeze until needed. The animals that froze to death on the slopes were bulldozed into heaps of a hundred, and left where they were. Geodetic maps were carefully marked to show the locations of each heap.

  It was, after all, a blessing that Reykjavik had been nuked. That meant half a million fewer people for the island’s resources to feed.

  When Malibert was not calculating load factors, he was out in the desperate cold, urging on the workers. Sweating navvies tried to muscle shrunken fittings together in icy foxholes that their body heat kept filling with icewater. They listened patiently as Malibert tried to give orders—his few words of Icelandic was almost useless, but even the navvies sometimes spoke tourist-English. They checked their radiation monitors, looked up at the storms overhead, returned to their work and prayed. Even Malibert almost prayed when one day, trying to locate the course of the buried coastal road, he looked out on the sea ice and saw a gray-white ice hummock that was not an ice hummock. It was just at the limits of visibility, dim on the fringe of the road crew’s work lights, and it moved. “A polar bear!” he whispered to the head of the work crew, and everyone stopped while the beast shambled out of sight.

  From then on they carried rifles.

  When Malibert was not (incompetent) technical adviser to the task of keeping Iceland warm or (almost incompetent, but learning) substitute father to Timothy Clary, he was trying desperately to calculate survival chances. Not just for them; for the entire human race. With all the desperate flurry of survival work, the Icelanders spared time to think of the future. A study team was created, physicists from the University of Reykjavik, the surviving Supply officer from the Keflavik airbase, a meteorologist on work-study from the University of Leyden to learn about North Atlantic air masses. They met in the gasthuis where Malibert lived with the boy, and usually Timmy sat silent next to Malibert while they talked. What they wanted was to know how long the dust cloud would persist. Some day the particles would finish dropping from the sky, and then the world could be reborn—if enough survived to parent a new race, anyway. But when? They could not tell. They did not know how long, how cold, how killing the nuclear winter would be. “We don’t know the megatonnage,” said Malibert, “we don’t know what atmospheric changes have taken place, we don’t know the rate of isolation. We only know it will be bad.”

  “It is already bad,” grumbled Thorsid Magnesson, Director of Public Safety. (Once that office had had something to do with catching criminals, when the major threat to safety was crime.)

  “It will get worse,” said Malibert, and it did. The cold deepened. The reports from the rest of the world dwindled. They plotted maps to show what they knew to show. One set of missile maps, to show where the strikes had been—within a week that no longer mattered, because the deaths from cold already began to outweigh those from blast. They plotted isotherm maps, based on the scattered weather reports that came in—maps that had to be changed every day, as the freezing line marched toward the Equator. Finally the maps were irrelevant. The whole world was cold then. They plotted fatality maps—the percentages of deaths in each area, as they could infer them from the reports they received, but those maps soon became too frightening to plot.

  The British Isles died first, not because they were nuked but because they were not. There were too many people alive there. Britain never owned more than a four-day supply of food. When the ships stopped coming they starved. So did Japan. A little later, so did Bermuda and Hawaii and Canada’s offshore provinces; and then it was continents’ turn.

  And Timmy Clary listened to every word.

  The boy didn’t talk much. He never asked after his parents, not after the first few days. He did not hope for good news, and did not want bad. The boy’s infection was cured, but the boy himself was not. He ate half of what a hungry child should devour. He ate that only when Malibert coaxed him.

  The only thing that made Timothy look alive was the rare times when Malibert could talk to him about space. There were many in Iceland who knew about Harry Malibert and SETI, and a few who cared about it almost as much as Malibert himself. When time permitted they would get together, Malibert and his groupies. There was Lars the postman (now pick-and-shovel ice excavator, since there was no mail), Ingar the waitress from the Loftleider Hotel (now stitching heavy drapes to help insulate dwelling walls), Elda the English teacher (now practical nurse, frostbite cases a specialty). There were others, but those three were always there when they could get away. They were Harry Malibert fans who had read his books and dreamed with him of radio messages from weird aliens from Aldebaran, or worldships that could carry million-person populations across the galaxy, on voyages of a hundred thousand years. Timmy listened, and drew sketches of the worldships. Malibert supplied him with dimensions. “I talked to Gerry Webb,” he said, “and he’d worked it out in detail. It is a matter of rotation rates and strength of materials. To provide the proper simulated gravity for the people in the ships, the shape has to be a cylinder and it has to spin—sixteen kilometers is what the diameter must be. Then the cylinder must be long e
nough to provide space, but not so long that the dynamics of spin cause it to wobble or bend—perhaps sixty kilometers long. One part to live in. One part to store fuel. And at the end, a reaction chamber where hydrogen fusion thrusts the ship across the Galaxy.”

  “Hydrogen bombs,” said the boy. “Harry? Why don’t the bombs wreck the worldship?”

  “It’s engineering,” said Malibert honestly, “and I don’t know the details. Gerry was going to give his paper at the Portsmouth meeting; it was one reason I was going.” But, of course, there would never be a British Interplanetary Society meeting in Portsmouth now, ever again.

  Elda said uneasily, “It is time for lunch soon. Timmy? Will you eat some soup if I make it?” And did make it, whether the boy promised or not. Elda’s husband had worked at Keflavik in the PX, an accountant; unfortunately he had been putting in overtime there when the follow-up missile did what the miss had failed to do, and so Elda had no husband left, not enough even to bury.

  Even with the earth’s hot water pumped full velocity through the straining pipes it was not warm in the gasthuis. She wrapped the boy in blankets and sat near him while he dutifully spooned up the soup. Lars and Ingar sat holding hands and watching the boy eat. “To hear a voice from another star,” Lars said suddenly, “that would have been fine.”

  “There are no voices,” said Ingar bitterly. “Not even ours now. We have the answer to the Fermi paradox.”

  And when the boy paused in his eating to ask what that was, Harry Malibert explained it as carefully as he could:

  “It is named after Enrico Fermi, a scientist. He said, ‘We know that there are many billions of stars like our sun. Our sun has planets, therefore it is reasonable to assume that some of the other stars do also. One of our planets has living things on it. Us, for instance, as well as trees and germs and horses. Since there are so many stars, it seems almost certain that some of them, at least, have also living things. People. People as smart as we are—or smarter. People who can build spaceships, or send radio messages to other stars, as we can.’ Do you understand so far, Timmy?” The boy nodded, frowning, but—Malibert was delighted to see—kept on eating his soup. “Then, the question Fermi asked was, ‘Why haven’t some of them come to see us?’”

  “Like in the movies,” the boy nodded. “The flying saucers.”

  “All those movies are made-up stories, Timmy. Like Jack and the Beanstalk, or Oz. Perhaps some creatures from space have come to see us sometime, but there is no good evidence that this is so. I feel sure there would be evidence if it had happened. There would have to be. If there were many such visits, ever, then at least one would have dropped the Martian equivalent of a McDonald’s Big Mac box, or a used Sirian flash cube, and it would have been found and shown to be from somewhere other than the Earth. None ever has. So there are only three possible answers to Dr. Fermi’s question. One, there is no other life. Two, there is, but they want to leave us alone. They don’t want to contact us, perhaps because we frighten them with our violence, or for some reason we can’t even guess it. And the third reason—” Elda made a quick gesture, but Malibert shook his head—“is that perhaps as soon as any people get smart enough to do all those things that get them into space—when they have all the technology we do—they also have such terrible bombs and weapons that they can’t control them anymore. So a war breaks out. And they kill themselves off before they are fully grown up.”

  “Like now,” Timothy said, nodding seriously to show he understood. He had finished his soup, but instead of taking the plate away Elda hugged him in her arms and tried not to weep.

  The world was totally dark now. There was no day or night, and would not be again for no one could say how long. The rains and snows had stopped. Without sunlight to suck water up out of the oceans there was no moisture left in the atmosphere to fall. Floods had been replaced by freezing droughts. Two meters down the soil of Iceland was steel hard, and the navvies could no longer dig. There was no hope of laying additional pipes. When more heat was needed all that could be done was to close off buildings and turn off their heating pipes. Elda’s patients now were less likely to be frostbite and more to be the listlessness of radiation sickness as volunteers raced in and out of the Reykjavik ruins to find medicine and food. No one was spared that job. When Elda came back on a snowmobile from a foraging trip to the Loftleider Hotel she brought back a present for the boy. Candy bars and postcards from the gift shop; the candy bars had to be shared, but the postcards were all for him. “Do you know what these are?” she asked. The cards showed huge, squat, ugly men and women in the costumes of a thousand years ago. “They’re trolls. We have myths in Iceland that the trolls lived here. They’re still here, Timmy, or so they say; the mountains are trolls that just got too old and tired to move anymore.”

  “They’re made-up stories, right?” the boy asked seriously, and did not grin until she assured him they were. Then he made a joke. “I guess the trolls won,” he said.

  “Ach, Timmy!” Elda was shocked. But at least the boy was capable of joking, she told herself, and even graveyard humor was better than none. Life had become a little easier for her with the new patients—easier because for the radiation-sick there was very little that could be done—and she bestirred herself to think of ways to entertain the boy.

  And found a wonderful one.

  Since fuel was precious there were no excursions to see the sights of Iceland-under-the-ice. There was no way to see them anyway in the eternal dark. But when a hospital chopper was called up to travel empty to Stokksnes on the eastern shore to bring back a child with a broken back, she begged space for Malibert and Timmy. Elda’s own ride was automatic, as duty nurse for the wounded child. “An avalanche crushed his house,” she explained. “It is right under the mountains, Stokksnes, and landing there will be a little tricky, I think. But we can come in from the sea and make it safe. At least in the landing lights of the helicopter something can be seen.”

  They were luckier than that. There was more light. Nothing came through the clouds, where the billions of particles that had once been Elda’s husband added to the trillions of trillions that had been Detroit and Marseilles and Shanghai to shut out the sky. But in the clouds and under them were snakes and sheets of dim color, sprays full of dull red, fans of pale green. The aurora borealis did not give much light. But there was no other light at all except for the faint glow from the pilot’s instrument panel. As their eyes widened they could see the dark shapes of the Vatnajökull slipping by below them. “Big trolls,” cried the boy happily, and Elda smiled too as she hugged him.

  The pilot did as Elda had predicted, down the slopes of the eastern range, out over the sea, and cautiously back in to the little fishing village. As they landed, red-tipped flashlights guiding them, the copter’s landing lights picked out a white lump, vaguely saucer-shaped. “Radar dish,” said Malibert to the boy, pointing.

  Timmy pressed his nose to the freezing window. “Is it one of them, Daddy Harry? The things that could talk to the stars?”

  The pilot answered: “Ach, no, Timmy—military, it is.” And Malibert said:

  “They wouldn’t put one of those here, Timothy. It’s too far north. You wanted a place for a big radio telescope that could search the whole sky, not just the little piece of it you can see from Iceland.”

  And while they helped slide the stretcher with the broken child into the helicopter, gently, kindly as they could be, Malibert was thinking about those places, Arecibo and Woomara and Socorro and all the others. Every one of them was now dead and certainly broken with a weight of ice and shredded by the mean winds. Crushed, rusted, washed away, all those eyes on space were blinded now; and the thought saddened Harry Malibert, but not for long. More gladdening than anything sad was the fact that, for the first time, Timothy had called him “Daddy.”

  In one ending to the story, when at last the sun came back it was too late. Iceland had been the last place where human beings survived, and Iceland had finally sta
rved. There was nothing alive anywhere on Earth that spoke, or invented machines, or read books. Fermi’s terrible third answer was the right one after all.

  But there exists another ending. In this one the sun came back in time. Perhaps it was just barely in time, but the food had not yet run out when daylight brought the first touches of green in some parts of the world, and plants began to grow again from frozen or hoarded seed. In this ending Timothy lived to grow up. When he was old enough, and after Malibert and Elda had got around to marrying, he married one of their daughters. And of their descendants—two generations or a dozen generations later—one was alive on the day when Fermi’s paradox became a quaintly amusing old worry, as irrelevant and comical as a fifteenth-century mariner’s fear of falling off the edge of the flat Earth. On that day the skies spoke, and those who lived in them came to call.

  Perhaps that is the true ending of the story, and in it the human race chose not to squabble and struggle within itself, and so extinguish itself finally into the dark. In this ending human beings survived, and saved all the science and beauty of life, and greeted their star-born visitors with joy…

  But that is in fact what did happen!

  At least, one would like to think so.

  AFTERWORD

  FIFTY YEARS AND COUNTING

  I DON’T KNOW IF Johnny Appleseed ever went back, after dropping all those seeds over all those years, to see how the trees had grown. I think I know how he would have felt if he had, though. In much the same way, what we have here is a big slice of my life—half a century’s worth of those of my short stories and novelettes that best pleased my estimable editor, James Frenkel. Some of these stories were written while I was in my twenties, some when I was well into my—well, never mind exactly which decade we’re talking about. Many were written in whatever home I was living in at the time—the big old New Jersey house, where I could look from my third-floor office across the river at the town of Red Bank, or my present office in my almost as big (but never big enough) home in Palatine, Illinois. Many were written wherever I happened to be at the time—sitting on a wharf in the East River on sunny summer days, or in an airplane, in a hotel, on a ship or (in at least one case) in the pro station of the Air Force Base of Chanute Field, Illinois, the only place where I could use my typewriter late on a Saturday night.
