Chapter One

My hands were slick with salt water and rust when I pulled the intake grate free. It weighed forty kilograms, maybe more, and it dragged against the hull of the desalination plant with a sound like a dog tearing its own throat. The north wind was hitting the dome at a forty-degree angle, shaking the fence of disputed stones that lined the access road. I dropped the grate. It clattered on the concrete, a sharp, final noise that cut through the low, persistent hum vibrating in my molars.

I am Lois Quimby. I am forty-two. I have a berth mortgage on the generation ship Aethelgard, and I have a father who died in 1998, his name stained in a file I cannot open. The hum is not in the machine. It is in the walls. It has been in the walls for twenty-six years, growing louder every time I touch the redacted pages of his audit. I came here to clear his name. I came here to prove that the clerical error was a lie. The Director, a man named Halloway who has never met my father, rejected my appeal in one sentence. He called it emotionally compromised. He did not look at the paper. He looked at me, his face pale and still, and the air in the office thickened until I could taste the dust.‌​⁠⁠‌‌‌​​‌​​‍‌‍‌​⁠‍⁠‌⁠⁠‍⁠‌​​​​​​​​​​​​​​‌⁠⁠​⁠⁠⁠‍​‌‌‍‍‍‍​⁠‌​‌⁠‌⁠‍‌‌⁠‍​‌⁠⁠‍​

Chapter Two

I found the ledger in my father’s old desk, hidden behind a false back made of compressed sawdust. The entries were dated 1998. The numbers did not match the official record. They matched the hum. As I copied the figures by hand, the sound in my teeth shifted from a drone to a rhythmic thumping, syncing with my own pulse. I wrote the numbers on a scrap of paper. The paper felt warm under my fingers, like skin. I realized then that the "error" was a cover-up. Halloway had buried my father to protect his own early career. The truth was not a fact to be proven. It was a weight to be carried. He remembered, too, forty-two of the Tide Clock — the kind of small thing a man carries for no reason he could name.

The hydroponic tray on my windowsill was struggling. The greens were pale, their leaves curling inward against the dry air of the shop. I touched one leaf. It was gritty with salt. The single bell rang out across the suburbs, marking the end of the work shift. The sound was clean, sharp, and it cut the hum in half. For a second, the silence was heavier than the noise. I looked at the fence of disputed stones again. They were grey, jagged, and unmoving. They had been there before the dome, before the ship, before my father died. They would be there after me.‌​⁠⁠‌‌‌​​‌​​‍‌‍‌​⁠‍⁠‌⁠⁠‍⁠‌​​​​​​​​​​​​​​‌⁠⁠​⁠⁠⁠‍​‌‌‍‍‍‍​⁠‌​‌⁠‌⁠‍‌‌⁠‍​‌⁠⁠‍​

Chapter Three

I brought the ledger to Halloway’s office. He did not look at the paper. He looked at me. "Your father was not a man, Lois," he said. His voice was flat, bureaucratic, stripped of any human warmth. "He was a process." The room’s air thickened. The hum stopped abruptly. The ringing silence that followed was physical, pressing against my eardrums. I did not speak. I did not argue. I placed the ledger on his desk. The paper was warm. He did not touch it. He pointed to the door.

I was suspended without pay. I walked back to my small apartment, the walls of which seemed to breathe in and out with the rhythm of the city’s ventilation systems. The dust motes in the light from the single window formed the shape of the ledger’s numbers. I saw them, and I did not look away. I sat on the edge of my berth. The mortgage payment was due in three days. I had no income. I had no reference. I had a secret that weighed more than the salt in my blood. The uncanny was domestic. It was the way the light fell on the floorboards. It was the way the silence had a texture, like wet sand.‌​⁠⁠‌‌‌​​‌​​‍‌‍‌​⁠‍⁠‌⁠⁠‍⁠‌​​​​​​​​​​​​​​‌⁠⁠​⁠⁠⁠‍​‌‌‍‍‍‍​⁠‌​‌⁠‌⁠‍‌‌⁠‍​‌⁠⁠‍​

Chapter Four

I decided to stop fighting the system. I began to document the hum. I recorded its frequency and duration in a private journal, the Gravenhurst pill box serving as my cover. I wrote the numbers down, over and over, until the ink blurred. I accepted that the truth was not a fact. It was a weight. Halloway’s office became a sealed room in my mind, a closed space where the past was preserved in amber. I would not go back. I would not ask for justice. Justice was a word for people who had time to spare. I had a debt to pay and a ghost to carry.

I submitted my resignation. I did not ask for a reference. I walked out of the building, the hum finally silent in my head, replaced by the ordinary noise of traffic. The cost was my career and my father’s reputation, which remains tarnished in the official record. The victory was internal. I had released the ghost. I stood on the sidewalk, watching the city move. The north wind was still blowing, but it no longer felt like a threat. It was just wind. I touched my pocket, where the last page of the ledger was folded. The paper was warm. I did not open it. I walked home, an ordinary woman carrying an ordinary secret, the weight of it settled into my bones.‌​⁠⁠‌‌‌​​‌​​‍‌‍‌​⁠‍⁠‌⁠⁠‍⁠‌​​​​​​​​​​​​​​‌⁠⁠​⁠⁠⁠‍​‌‌‍‍‍‍​⁠‌​‌⁠‌⁠‍‌‌⁠‍​‌⁠⁠‍​

Chapter Five

The door to my apartment was left open on purpose. I did not close it. I wanted the air to move through the space, to carry the scent of salt and rust out into the street. The hydroponic tray was on the windowsill. The greens were still struggling, but one leaf had unfurled slightly, catching the last of the light. I looked at the fence of disputed stones one last time from the window. They were still there. They were still grey. I closed the journal. I sat in the chair. The silence was not empty. It was full. It was mine.‌​⁠⁠‌‌‌​​‌​​‍‌‍‌​⁠‍⁠‌⁠⁠‍⁠‌​​​​​​​​​​​​​​‌⁠⁠​⁠⁠⁠‍​‌‌‍‍‍‍​⁠‌​‌⁠‌⁠‍‌‌⁠‍​‌⁠⁠‍​
