The Decryption

Eleanor did not report the signal.

This was, strictly speaking, a violation of Post 7's standing orders, which required any anomalous detection above a confidence threshold of 0.6 to be relayed to Sector Command within the hour. She had let four hours pass. She told herself she was verifying the data. She was not entirely lying.

The recording sat in her console's isolated buffer, forty-one seconds of a woman's voice singing four lines of a lullaby before dissolving back into the hiss of Sector 9's silence. Eleanor had listened to it eleven times. Each time, the hair on her arms stood up in the same place, at the same word — *little* — as if her body had found something in the syllable that her mind could not yet name.

The station was three decks of riveted plate and recycled air, built forty years ago when listening posts were still considered a reasonable use of government money, back before the Array had swallowed every discretionary credit in the sector's budget. Post 7 had two live crew, Eleanor and a maintenance engineer named Boyd who spent most of his shifts in the reactor well and most of his silences avoiding her, for reasons she had stopped trying to understand around year two. The rest of the station's apparent population was ghosts: automated systems, a skeleton AI that ran life support and nothing else, and the accumulated debris of two generations of analysts who had sat in her chair before her and left behind coffee stains, a taped-up star chart, and one truly excellent set of noise-cancelling headphones that she had never returned to inventory.

She was alone with the recording, and she wanted to keep it that way for a little longer.

The old station terminal did not have decryption software worth the name — Post 7's budget line for cryptographic tools had been zeroed out eleven years ago in a round of cuts that had also taken the second live crew slot, the hydroponics bay, and Boyd's hazard pay. What Eleanor had instead was patience, a decent grounding in signal theory from a doctorate she'd never finished, and a stubborn conviction that the lullaby was not the message. It was the envelope.

She had noticed it on the fourth listen. Beneath the audible layer — the voice, the melody, the warm analog hiss that made it sound like something recorded on equipment fifty years older than anything currently in production — there was a second structure. A modulation riding under the carrier frequency, too regular to be noise, too fine to be anything the original transmission equipment (whatever that had been, wherever it had been, whenever it had been) would have introduced by accident.

She spent an hour proving to herself it wasn't an artifact of the Array's own receivers. It wasn't. She spent a second hour building a filter crude enough to strip the audible lullaby away and leave the substrate exposed.

What she got, when she finally isolated it, was a lattice of pulses. Not language. Not Morse, not any of the historical binary encodings she checked against the station's threadbare reference library. Numbers, though — that much resolved almost immediately, the way a shape resolves out of static when you've been staring at it long enough that your brain simply gives up resisting the pattern. Groups of numbers, repeating, structured.

Coordinates.

She sat back from the console and did not move for a while.

Coordinates, embedded under a lullaby, transmitted from a patch of sky that contained nothing — no star, no debris field, no derelict registered in any survey Post 7's database had ever ingested, going back to the founding of the listening network itself. Sector 9 was not merely quiet. It was empty in the specific, documented, triple-checked way that made astronomers write papers about the *absence* of things, because an absence that clean was itself a kind of anomaly.

"You're going to want to see this," she said aloud, to no one, because Boyd was in the reactor well and the skeleton AI did not count as company no matter how many hours a week she spent talking to it.

She ran the coordinate set through the station's stellar catalog anyway, out of the same compulsive thoroughness that had kept her running the same lullaby eleven times. The catalog returned nothing. She widened the search radius. Nothing. She widened it again, out past any distance that made sense for a signal this strong to have traveled without significant attenuation, and there — flagged with a low-confidence asterisk, the kind the catalog used for entries built from incomplete survey passes — was a designation. Not a star. Not a planet. A *drift marker*, the kind of provisional tag assigned to objects detected once, briefly, and never confirmed again. Object 9-4471. Detected eighteen years ago by a since-decommissioned survey probe, logged, deprioritized, forgotten.

Eighteen years. Eleanor did the arithmetic without wanting to. Whatever Object 9-4471 was, it had been sitting in that patch of nothing for at least eighteen years, and possibly much longer, waiting to be seen twice.

She pulled the probe's original passive-scan data, ancient and compressed and barely readable in the station's outdated file format, and found a single frame — one frame, out of thousands, where the automated imaging system had caught something before losing the object again in the noise of its own sensor drift. It was not a ship. It was not obviously anything. It was a shape, angular in a way that felt deliberate rather than geological, dark against the deeper dark behind it, and it was, by the probe's own rough photometry, enormous — kilometers, not meters, though the resolution was too poor to say more than that with any confidence.

The lullaby had come from there. Or near there. Or from something that wanted the coordinates of that shape carried inside forty-one seconds of a song that should not exist, sung in a voice with formant frequencies so precisely human that Eleanor's decoder had returned a 94% confidence match against baseline human vocal tract modeling — a confidence score she had checked four times because it seemed, on its face, impossible. No radio source that far from any inhabited system should sound like a person. And yet.

She thought about the woman's voice again. *Sleep, little star.* Whoever — whatever — had sent it had encoded something that sounded like comfort, wrapped around something that read like a location, and sent it toward a listening post that had no reason to exist except that a bureaucracy forty years dead had once decided someone should keep an ear turned toward the silence, on the vanishingly small chance that the silence ever said something back.

It had.

Eleanor finally opened a channel to Sector Command, four hours and eleven minutes after the signal had first crossed her threshold. She kept her voice as flat and procedural as she could manage, reading off frequency, duration, confidence scores, the coordinate lattice she'd extracted, careful not to say the word *lullaby* until she absolutely had to, because she already knew how it would sound to a duty officer half a shift removed from finishing a report and going home. She said it anyway, in the end, because the transcript required completeness and because some stubborn part of her wanted it on the record, precisely as she'd heard it, before anyone with more authority than her got the chance to sand the strangeness off the edges.

The response came back nine hours later — the round-trip lag of a message crossing real distance at the speed of light was not something Eleanor had ever gotten used to, even after three years, the way it turned every conversation with anyone off-station into something closer to correspondence than dialogue. Nine hours of turnaround. Nine hours in which she sat with the frame from the old probe open on her second monitor, that dark angular nothing suspended against a field of stars, and did not decide what she believed about it.

The response, when it finally arrived, was three lines long. It thanked her for her diligence. It instructed her to preserve all raw data and cease further independent analysis pending review. And it informed her, in the flat administrative language that Sector Command used for everything from routine maintenance schedules to matters that would reorganize the rest of her life, that a scout vessel was being diverted to Post 7's coordinates, ETA six days, to conduct an in-person assessment.

Eleanor read the message twice. Then she looked at the small addendum beneath the official text — a personal note, evidently added by whichever duty officer had actually drafted the response, the kind of thing that wasn't supposed to survive the formatting but sometimes did.

*Whatever you found, don't tell anyone else yet. Command wants this contained. — T.O. Reyes*

She did not know a T.O. Reyes. She had never heard the name in three years of routine correspondence with Sector Command. And there was something in the wording — *contained*, not *reviewed*, not *investigated* — that made the recycled air of the control room feel suddenly thinner than it had a moment before.

Boyd found her still sitting there two hours later, when he finally surfaced from the reactor well for his evening ration. He took one look at her face and said, with the flat, weary directness of a man who had learned long ago not to expect good news from her expressions, "What."

Eleanor turned her monitor so he could see the frame — the dark shape, the drift marker, the eighteen-year-old gap in a survey no one had thought to finish.

"Something's coming to look at us," she said. "In six days."

"Something like what?"

She thought about the voice singing to something it called *little star*, and the numbers hidden beneath it, patient and precise, waiting eighteen years to be found by anyone at all.

"I don't know yet," she said. "But it already knows where we are."
