I. The signal arrived on a Tuesday in the autumn of 1924, which was an unlucky day for a signal to arrive because Tuesdays were when Julian Ashworth went to the city to visit the university library and the observatory was empty. This was not accidental — Julian had deliberately scheduled his library visits for Tuesday so that the observatory would be unmonitored, because what he was doing in the observatory was not part of his official duties at Göttingen, and he wanted no one to know. The signal came through the new Marconi receiver, a machine that cost more than most people earned in a year and that Julian had installed himself with hands that shook slightly because he understood, on some level, that he was about to receive something that would change everything. It was not radio static. It was not atmospheric interference. It was a sequence of numbers — primes, he recognized immediately, though it took him three hours to confirm it: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47. The pattern repeated every forty-seven primes, with a pause of exactly three seconds between each repetition. Julian sat in the dark observatory and stared at the oscilloscope trace, the green line jumping with mathematical precision from a place that should have been silent. He thought of Göttingen, of quantum mechanics and wave equations and the beautiful, clean world of theoretical physics. He thought of the ocean off Fire Island, where a shipwreck from centuries ago — or perhaps from no century at all, because the metal of the recovered artifacts did not match any known alloy — had been emitting this signal for reasons that physics could not explain. He called his sister Cordelia from a payphone on the corner of Fifth and Thirty-Fifth Street. She was singing at the Algonquin Club that night, between sets, and he could hear the music through the phone — a jazz band playing something fast and bright that had nothing to do with what he had found. "Cordy," he said when she answered. "I found something." "Julian? It is past midnight. What —" "It is from the ocean. A signal. It is math, Cordy. Pure mathematics, coming from the bottom of the Atlantic. Someone put it there. Or something." She was quiet for a moment. Then she said, "Come home. I will make tea. You can show me in the morning." "I do not want to show you. I want to show the world." "The world is not ready." "Nobody is ever ready." II. Ashworth Manor was the kind of house that made people who had not inherited it feel strange emotions that they could not name. It sat on three hundred acres of Long Island shoreline, with a facade of white stone and windows that caught the light in a way that made visitors feel, for a moment, that they were looking at something that belonged to a different century. The family that owned it had made its money in railroads before the war and had spent it on art and estates and appearances since the armistice. Richard Ashworth, the patriarch, was a man who had built something enormous and watched it disappear in a single day in October 1929 and had not entirely recovered. He spent his days in the library, drinking bourbon and reading newspapers that told him, every day, that the world was smaller and poorer than it had been the day before. Catherine, his wife, hosted parties. This was not a choice but a compulsion. The parties were magnificent — orchestras from the city, imported food, flowers shipped from Florida — and they were also a form of denial. If she could throw a party that looked exactly like a party from 1920, then perhaps the world had not changed at all. Julian was the youngest son. He had a physicist's mind and a poet's sensibility and a face that women found attractive because it was always slightly surprised, as if he were looking at the world and finding it both beautiful and incomprehensible, which he was. Violet Crane was Julian's cousin — not by blood, but by something closer. She was an artist who had grown up visiting Ashworth Manor and had started staying for months at a time, painting in the east wing studio that Richard had had converted from a guest room. Her paintings were abstract, composed of swirling colors and geometric patterns that looked, to anyone who knew about the signal, like visual translations of the prime number sequence. "You are painting the signal again," Julian said, standing in her studio one afternoon in 1926, watching her mix ultramarine with a touch of cadmium yellow. "It is not the signal," she said. "It is what the signal feels like." "How does it feel?" She put down the brush. Looked at him. "Like being lonely in a room full of people." III. The stock market crashed in October 1929. Julian was in the observatory when the news reached the house. He saw the telegram arrive, saw his father open it in the library with a face that went from colorless to ashen, saw his mother close the piano lid in the music room and walk, without moving her arms, to the garden where she stood for twenty minutes staring at a dead rose bush. The parties stopped. The flowers stopped. The orchestra stopped. The house began, slowly, to become what it had always been underneath: a building too large for the family that owned it, holding people who loved each other and did not know how to show it. Julian continued his research. The signal grew stronger — or perhaps the receiver was simply more sensitive. The prime number sequence was now accompanied by a secondary pattern, a modulation that suggested the numbers were not the message but the key. The message was in the modulation. Cordelia continued to sing. She moved to a smaller club in Greenwich Village and played for tips and a salary that was probably less than what she used to make for one night at the Algonquin. But she sang with a quality that Julian had never heard before — something darker, something truer. She had lost her glamorous life, and in losing it, had found her voice. Violet continued to paint. Her work grew darker, more intense. The swirling colors became almost violent, the geometric patterns fragmented and reassembled with a desperation that suggested the paintings were not art but evidence. Richard stopped reading newspapers. Catherine stopped counting the days until the next party. Edward, the older brother, started talking about selling the estate. Julian sat in the observatory at night and listened to the signal and tried to decode the modulation and understood, with a certainty that was neither happy nor sad, that whatever the message was, it was not meant for the people who owned Ashworth Manor. It was meant for everyone. And everyone was too busy destroying themselves to listen. IV. He transmitted the signal on a night in the spring of 1932. The observatory was cold — the coal supply had run out weeks ago, and he had burned furniture to keep the instruments from freezing. The receiver was a patchwork of salvaged parts. The transmitter was something he had built himself from scrap. Cordelia was in the next room, in the small bedroom that had been a study, sleeping on a mattress on the floor. Violet was in the east wing, painting by candlelight. The house was breathing its slow breath — the sound of a building that is losing the warmth of its occupants. Julian calibrated the transmitter. He had the decoded message ready — a mathematical description of the signal's source, its properties, its implications. He did not know what the source was. He did not know who had placed it in the ocean. But he knew that it was real, and that it was persistent, and that it was trying to communicate something that the world needed to hear. He pressed the transmit button. The signal left the observatory in a beam of radio waves, crossed the lawn, rose above the tree line, and went outward across the Atlantic toward whatever had sent the original. It would take fractions of a second to reach the ocean floor. It might take hours for a response to arrive. It might never come. Julian held the button down until his hand ached. Then he released it. He sat down on the floor of the observatory, back against the telescope mount, and closed his eyes. Somewhere in the house, Cordelia began to sing. Her voice was muffled by walls and distance and sleep, but he could hear the notes — low, uncertain, finding their way upward like the signal finding its way across the ocean. He did not know if he had saved anything. He did not know if he had destroyed anything. He only knew that he had sent the message, and that was enough. It had to be enough. Outside, the sky was clear and full of stars, and the wind was moving across the Long Island shore, and the Atlantic was dark and deep and old, and somewhere beneath its surface, a signal waited.
