第8章 The Redacted Sky

The probe records took her another week, because they were not where the official summaries said they were. The public record was tidy and grim. The atmosphere had turned toxic, the surface had been declared unrecoverable, the probes sent up in the first years of the collapse had confirmed the worst, and the doors had been sealed to save what could be saved. Every schoolchild in Undercity Seven had learned that story, and Elena had believed it the way she believed the floor under her feet. But the floor had a trapdoor in it, and she had found it. The originals were in the lowest archive tier, in cabinets that had not been opened since before the maintenance chief's predecessor's predecessor. They were the first survey data, the raw telemetry from the probes, and they were not what the summaries claimed. The toxicity readings were there, yes, real and sobering. But so were the recovery projections, the soil chemistry, the water signatures, the processor activity readings from the old life support network. Green patches, the files said, in the valleys where the processors ran. Water sources. A biosphere, thin and wounded, but alive. None of it had ever made it into the public record. The summaries had simply stopped, the way a story stops when someone decides it should, and the city had built its whole idea of the world on the pages that came after. The recovery projections were dated and numbered, a decade of them, and they told a story the summaries had never mentioned. The processors were working. The air in the valleys was improving, slowly, year by year, the numbers climbing like a patient's temperature chart. One report, dated forty years after the collapse, was annotated in a hand that had been dead for decades: "If the processors hold, the valleys will be habitable within our grandchildren's lifetime. The city must be told." The annotation was the worst of it. Someone had believed, forty years ago, that the city must be told, and the city had not been told, and the someone had died, and the processors had held, and the valleys had healed, and the record had been sealed anyway. Elena sat with her hand resting on the annotated report and tried to imagine the person who had written it, an engineer like her, a hundred years closer to the surface, who had done her job and been erased for it. Elena read the originals twice, by lantern light, because the archive's ceiling lights had been dead for years. When she was done she sat for a long time with her hand resting on the file, and she did not know whether to be afraid or furious or both. The lie was not an accident. The numbers had been curated, edited, shaped into a story that made the sealing inevitable and the dark comfortable. Someone had decided, a century ago, that the people below were better off believing the world was dead. Someone had decided, and every Council since had maintained it, and the whole city had breathed the lie like air. The clicking came through the walls, patient and regular, and Elena thought about the machine at the end of the trace, the processor that had been left running to scrub the sky, and she understood that the lie and the machine were two halves of the same thing. The machine kept the world alive in secret. The lie kept the people below from knowing it. She should have told someone. That was the first thought she had every morning, and she had it again now, standing in the dark with the truth in her hands. But she had watched herself lie to Daniel, watched herself forge a repair order, watched the shift supervisor accept it, and she had learned something she did not like: the secret was already costing her, and it would cost more. The city was a careful place, and that was precisely the problem, because the people who kept the records did not take kindly to engineers who read the ones they had hidden. The next day, a records clerk mentioned, in passing, that the deepest archive tier was scheduled for permanent sealing at the end of the month. Routine records retirement, the clerk said. The old film would be moved to the vault, the cabinets cleared, the tier closed off for good. Elena stood in the corridor and heard the words the way she would have heard a door being locked, and she understood what they meant. The evidence was going away. The originals she had read, the annotated report, the recovery projections, all of it was scheduled to be buried somewhere she could not reach, and once it was gone, there would be no proof that the lie had ever been a lie. She did not know if the clearing was an accident of bureaucracy or something more deliberate. She only knew she was running out of time to be sure. She spent that night in her quarters, staring at the ceiling, and the clicking went on, patient and regular, and she tried to find a way out that did not involve going back up, and she could not find one. The evidence was going to be buried. The machine would go on breathing in secret, and the valley would go on healing in secret, and the last living thing on the surface would live and die without the city ever knowing it had existed. The lie would win by default, quietly, the way lies do. The only way to stop it was to carry the truth down with her own hands, while she still could. Elena packed her tools in the dark, and she did not sleep, and by morning she had made her decision. She would go up before the records were sealed away. She would follow the line to its end, find the machine and whoever kept it running, and she would bring them back down with proof, so that the truth could not be buried while she was not looking. Daniel would keep the records straight, whether he knew it or not, because he had been keeping them straight for six years, and she would owe him an explanation when it was over, and she intended to be alive to give him one. She folded the blue cloth into her breast pocket and stood at her window, looking up at the painted sky of the dome, and for the first time in her life the ceiling felt like a lid. She did not know if Daniel would forgive her for the lie, or if the city would forgive her for the truth, or if the man at the end of the line would forgive her for bringing the whole world down on his head. She only knew she could not live with the alternative. She could not sit in her quarters while the machine starved and the valley died and the lie finished its work in silence, the way lies always finished their work if no one came to stop them. ---
