The signal arrived on a Tuesday in October, 1897, at precisely four minutes past eleven in the evening, when the Greenwich dome was open and the great refracting telescope stood aligned with the constellation of Centaurus. Edgar Wentworth was alone in the dome, as he usually was after nine o'clock, calibrating the instrument's tracking mechanism and drinking tea from a tin cup that had long since surrendered its interior enamel to rust.

The needle on the galvanometer jumped. Not the gradual sweep of solar interference or the erratic flicker of atmospheric static, but a sharp, rhythmic deflection that repeated itself with mathematical precision. Three short pulses. One long. Three short again.

Edgar set down his tea cup and pressed his ear to the earpiece of the recording apparatus, a device he had modified himself from surplus telegraph equipment. The pulses came through as audible clicks, each one precise to the millisecond, repeating every seventeen seconds without variation.

He checked the instrument three times. He recalibrated the frequency. He ran the analysis twice more. The signal was not atmospheric. It was not instrumental error. It was artificial, structured, and it was coming from a point 4.3 light-years away.

By morning, he had written a paper. By afternoon, he had submitted it to the Royal Astronomical Society. By the following week, the paper had been returned with a note in the president's handwriting: *Dr. Wentworth is reminded that the Society expects rigorous peer review prior to submission, and that amateur speculations regarding extraterrestrial intelligence fall outside the scope of our publications.*

Amateur. The word sat in his stomach like a stone. He was a Fellow of the Society. He had published papers on stellar parallax. He had measured the distance to Sirius to within three percent. And now he was an amateur, because the truth was too large for men who measured stars for a living.

He tried again with the Proceedings of the Royal Society. Same response, different handwriting. He approached individual Fellows in person, showing them his data, his recordings, his calculations. One man listened politely and then asked if Edgar had considered the possibility of interference from the telegraph office down the hill. Another suggested he take a holiday at the seaside. A third, an older man with kind eyes and trembling hands, pulled him aside and said quietly: "If what you say is true, Wentworth, then God forgive us all for pretending otherwise."

By spring of 1898, the transfer order arrived. Edgar was to be reassigned to the Hebrides outpost, a single-room observatory perched on a cliff overlooking the Atlantic, staffed by one man and supplied by boat once a month. It was not a punishment, technically. It was "reassignment." But everyone at Greenwich understood what it meant. You did not send a man to the edge of the world unless you wanted him to forget himself.

He went anyway.

Evelyn Crawford found him three months later, standing in the doorway of the Hebrides observatory with a leather satchel over her shoulder and rain in her hair. She had been his assistant at Greenwich for two years, one of the three women permitted to work in scientific institutions, tolerated but never accepted. She had watched him present his data. She had watched him be dismissed. And when the transfer order was announced, she had written to the Royal Society requesting a posting to the Hebrides outpost.

They had not spoken of the signal since Greenwich. They did not need to.

The Hebrides observatory was a single circular room built into the side of a cliff, with a dome that turned on rusted tracks and a telescope that was smaller than anything Edgar had used at Greenwich but perfectly adequate for what they needed to do. The boat came once a month with supplies and mail. The rest of the time, there was only the wind, the sea, and the sky.

They worked. They recorded. They watched the signal repeat itself every seventeen seconds, year after year, decade after decade, a metronome counting down to something neither of them could name.

Edgar aged. His hair went white. His hands developed a tremor that made his handwriting difficult to read. He kept journals, hundreds of pages of meticulous observation notes, each one dated and signed, each one ending with the same line: *Signal confirmed. No change in frequency, structure, or origin.*

Evelyn aged more slowly. She was twenty years younger than him, and her body resisted time the way his had surrendered to it. She conducted her own research on stellar radiation, publishing papers under her own name when the journals would accept them and under Edgar's name when they would not. She never complained.

England changed around them. The Empire that had seemed eternal began to crack at the edges. Wars came and went. Technologies emerged that Edgar could barely comprehend. The world grew louder, faster, more certain of itself with each passing decade, and the signal kept ticking in the background, seventeen seconds of artificial rhythm beneath the noise of human civilization.

Edgar died in the winter of 1947, at the age of ninety-one, in the same room where he had first heard the signal. Evelyn was there, holding his hand, reading from his journals aloud in a voice that did not shake. He did not hear her. He had stopped hearing anything for three days. But when she read the last entry, the one he had written the morning before he could no longer hold a pen, she understood that he had known, all along, that someone would need to be here when the fleet arrived.

*The signal is not a greeting,* he had written. *It is a warning. And warnings are only useful if someone is left to receive them.*

Evelyn lived another sixty years. She sustained herself through experimental treatments developed by scientists who did not know why she needed the extra time, who treated her as a medical curiosity rather than a woman carrying the last record of a world that would never read it. She kept working. She kept recording. She kept writing in the journals, her handwriting growing shakier but never stopping.

When the fleet arrived in the year 2347, four centuries after the signal had first been detected, Evelyn was the only human being left on Earth who remembered what the sky had looked like before the end. She sat in the observatory dome, the brass telescope dark beside her, and transmitted the data into the void.

Every journal. Every measurement. Every seventeen seconds of signal confirmed.

The transmission would never be received. The fleet would not care about data. The end of civilization would not be delayed by a library sent into the dark. But Evelyn transmitted it anyway, because that was what she had been here for, because someone had to be, because the alternative was to let the signal be the only thing that survived.

She sat in the dome and listened to the machine hum, and outside the dome, the first ships of the alien fleet appeared on the horizon like stars that had fallen to Earth and decided to stay.
