Floor, then no floor.
Jade's boot found a grate that wasn't there, and the rest of her followed it into a throat of black steel. On the way down a rung caught her hip. A bracket cracked against the back of her skull, and she saw white.
The water hit like a slammed hatch.
Cold closed over her head. It shoved the air out of her chest and filled her mouth with rust and something older, a coppery film that coated her tongue like pennies licked off a dead man's eyes.
She kicked. Nothing pushed back. Her pulse, the steady synthetic one the surgeons had given her, didn't speed up at all, and her lungs did the panicking for both of them.
Then the memory hit, the way they all hit since she'd torn the interface out, a jolt behind her left ear where the scar was. It smelled of chlorine. It showed her a tiled pool, a woman's hand around her wrist, a voice saying kick, baby, kick like you mean it. Her parents had raised her in basements and meeting halls, on pamphlets and cipher drills, and Jade had never set foot in a pool in her life. So how did the memory know the exact blue of those tiles?
Her lungs caught fire.
She clawed toward a smear of gray and broke through choking, spitting copper, alloy fingers clanking across wet concrete until they hooked a seam. Something bumped her shoulder in the black water, soft and yielding, and drifted off before she could decide what it was. She decided not to decide.
Far above, voices came down the shaft.
"Sweep lower access. She didn't go far."
She. Not they. B had been two steps behind her on the service stairs under the old market when the grate gave, and Jade had no idea which way B had run.
Jade pressed her cheek to the wall. Her chronometer pinged, soft as a fingernail on glass: 02:17. Then her locator spun, searched, and returned a line she had never seen in all her years working Neo-Eden's blind spots.
LOCATION UNKNOWN.
She tried the comm implant, the channel Cassin used when he wanted his favor repaid, the one she'd been ignoring since the drones came down. It gave her a dead hiss. The cracked handheld in her coat pocket, the one only B had the number for, had drowned with her.
Every blind spot on the station belonged to somewhere. That was the first rule she'd learned, and she had built a career on it, because a place the cameras forgot was a place the ledger remembered.
Neo-Eden didn't lose places.
So where had it put her? And why, in the dripping dark, did some small cold part of her feel less lost than it had in years?
Carpet.
Her boot sank into it and squelched, and Jade froze with the pistol up, because carpet made no sense. Industrial blue, worn to the weave down the middle, the kind that belonged in a shift office on Ring Three. Not two hundred meters under the waste decks.
On her left, a door stood open on a square of light.
"INSUFFICIENT CREDITS," a woman's voice sang out. "HAVE A WONDERFUL SHIFT."
It came from a vending machine against the back wall of a break room. From the doorway Jade traced its back to the wall and found no cord, no conduit, nothing. Behind its glass, in a single lit slot among forty dark ones, sat a carton of strawberry milk from a dairy that had folded before she learned to read.
She hadn't touched it.
She stepped in anyway. Plastic chairs. A laminate table peeling at one corner. On the corkboard hung a calendar twenty years out of date, the fourteenth circled in red marker, and beside the circle, in round letters, one word: cake.
Under the calendar, somebody had taped a child's drawing. A crayon sun, a crayon house, and a blue rectangle that might have been a pool or might have been a window.
Jade looked away from it. Her eyes went where they always went, to the things that told her who'd been in a room. Broom strokes curved through the dust around the table legs, and the door hinge had a new bolt in it. On the table sat a child's plastic cup with a cartoon rabbit on the side, turned so she couldn't see its face.
She knew the rabbit's left ear would be chewed before she turned the cup.
It was. Behind her ear, the scar gave one small jolt, like a word on the tip of her tongue.
Under the bench along the wall sat a pair of work boots with the laces double-knotted and the socks stuffed inside. Kensuke used to leave his by her door that way. She stood there looking at them longer than she had any reason to, and nothing moved, and the vending machine hummed to itself.
And her mind, which had always done what it was told, went wherever it wanted. It went to Kensuke's hands, the burn scar across two knuckles, the way he cracked them before he sat down to forge a signature. It went to Cassin's message and the pictures that came with it, and then to how furious she'd been at herself for crying over them on a transit car, in public, like a civilian. Then it went to the rent, due Thursday, which she paid in cash to a landlord who had never once asked her name.
The coffee maker ticked.
In the corner, on a warming plate, sat a mug with a brown ring at the bottom. Jade held her palm over it, and the sensors in her fingers read forty-one degrees. The coffee had skinned over but hadn't dried, and when she tilted the mug, it moved.
Someone had poured this. Someone had swept this floor and fixed that hinge and walked out of here in their socks, and not long ago. Her chronometer pinged 02:26. The room felt like somebody had stepped out for a minute and would be right back.
"HAVE A WONDERFUL SHIFT," the vending machine told her as she backed out.
Pop. Hiss. The spit of fat hitting a hot pan.
The smell reached her before the firelight did, cheap oil and something frying in it, and for one wrong second Jade stood in a kitchen her family had never had. Yellow curtains. A woman's back at a stove. A radio on the windowsill, and a small stool that her own feet dangled from.
Then the kitchen was gone, and there was a man.
He sat on an upturned crate beside a fire burning inside a cut-down chemical drum, a skillet balanced across its rim. He didn't raise his hands at the sight of her pistol. He raised his spatula.
"You're dripping on my floor," he said.
"It's concrete."
"It's my concrete. And every drop you shed down here, I end up boiling eventually." He pointed at a square of tarp. "Stand there. And turn your face away from that wall."
Jade looked. A dead camera hung bolted over the tent, its housing cracked, its cable chewed through.
"It's not connected."
"Old ones remember faces," he said. "Tarp."
She stood on the tarp. Through a thief's eyes the camp read like an inventory, and the inventory didn't add up. The man's beard was gray and matted to his collarbone, and grease had worked into every crease of his knuckles. But socks hung everywhere, dozens of them, drying on the tent lines, on a broken monitor, over the barrel of the rifle leaning on his crate.
And in the middle of all that filth sat a toaster.
It gleamed. Somebody had polished its chrome until the firelight slid off it, and a folded white cloth lay beside it, the only clean thing Jade had seen since the fall. The man followed her eyes and brightened.
"Real nichrome coils," he said. "Not that printed ribbon they use now. Browns both sides at once. You can't buy that anymore, you know. You can't buy that."
"Somebody left coffee on a hot plate back there," Jade said. "Still warm."
He flipped whatever was in the skillet. "Someone lives down here."
"Who?"
"Depends on the day."
He reached for a plastic jug and drank, and his sleeve rode up his left wrist. Numbers. Sixteen characters burned into the skin in the blocky Registry font Kensuke had spent three weeks teaching her to forge, and she couldn't stop looking at them. Her mind ran the checksum on its own, the way it ran any cipher left in front of it, and the checksum didn't resolve. She ran it again. It still didn't, and the scar under the numbers had ridged up thick and shiny, as if he'd gone back over the burn more than once.
He tugged the sleeve down. "Rude to stare."
Jade reached into her coat to check the shard. Dry in its sleeve, thank God. She drew it halfway out, and the man stopped chewing.
"Where," he said, "did you get Kensuke's key?"
"He's dead. Last night. Somebody killed him in an alley and wrote on him."
He looked at the shard for a long moment. Then he turned back to his skillet and said, to the pan and not to her, "I don't talk about Kensuke."
But he held out a battered reader anyway.
In B's diner the map had come to her in pieces, a broken schematic and a set of coordinates, through a dive that had left blood running out of her neural port. On the old man's reader it came up whole. KENSUKE / PRIVATE CACHE, and under the header a map that kept going where Neo-Eden's public schematics stopped.
The coordinates sat on it like a pin, a tunnel mouth under the Chromatek Boneyard. The red route didn't stop there. It ran under the Boneyard, past the reclamation sumps, down through layers she had never seen on any plan she'd bought or stolen, to a region marked with nothing but S4.
He pulled a tube from under the tent and unrolled it across the crate. Paper, gone soft as cloth at the edges, white lines on faded blue. It smelled like dust and old ink, and when she held Kensuke's screen over it, the red route matched the white lines turn for turn.
But the title block stopped her.
NEO-EDEN PRIMARY STRUCTURE. SECTOR 4. Below it sat a construction seal and a date nine years older than the Founding, the year stamped on every coin and slipped into every news feed Jade had ever muted.
"This was built before the station," she said. "Before there was anybody here to build it."
"Paper says a lot of things." He tapped the red line and took his finger back fast. "We don't go there anymore. And you can't go back up. Your pool's a sump. At four, the station purges the lower decks, and everything in that shaft goes out the vents with the rest of the garbage."
Her chronometer pinged. 02:44.
Seventy-six minutes, and the only way out led down. Jade had always left places by the back. She had never thought much about what was back there.
"That," the orb said, "was rude."
The old man had tossed it to her without warning, a dented sphere the size of a grapefruit held shut with three screws that didn't match. It had clanked off her alloy palm, and now it hung at her shoulder, a lens open, a thread of white light turning to look at her.
"He talks," the man said, polishing the toaster. "He'll keep you alive."
"Statistically questionable."
Jade missed half of it. She was sliding the shard back into its sleeve when the orb's light crossed its edge at a low angle, and her implant, zooming on reflex, caught something it had never bothered to flag.
Etching. Microscopic, along the shard's spine.
Jade turned the shard toward the fire.
Sixteen characters. A two-letter prefix, a date string, a checksum, in the same blocky font scarred into the old man's wrist. The prefix matched his.
The date didn't match anything she could live with.
It read this morning.
Kensuke had died last night in an alley, with symbols written on his body and this shard tucked under his collar. Cassin had sent her the pictures cropped close, skin and blood and nothing else, and she had never seen his face. Between that collar and her coat, the shard had passed through Protectorate evidence and Cassin's hands, and nobody else's that she knew of.
Dead men didn't sign things.
Somebody had signed this one. Either the body in the Protectorate's cold room wasn't Kensuke, or someone between that alley and her pocket wanted her to believe it wasn't. She thought of the symbols in Cassin's pictures, and she couldn't tell whether they looked like these strokes or whether she only wanted them to.
A summons. Or bait.
She stood. Her knee complained, and the servos in her arms whirred as she shoved the shard deep into her coat.
"You're going," the man said.
"I'm going to find out."
She told herself it was because the only way out led down. She didn't believe that either.
"Nobody finds anything down there." He set the white cloth down, folded in quarters. "It finds you."
For a day she had been mourning a dead man. Now she didn't know which frightened her more: finding Kensuke down here, or finding whatever had learned to wear his name. At 02:49 she stepped out of the firelight, and the cold was waiting for her.
Twenty minutes of dark. Then her knee quit.
A day of grief, and maybe the wrong man in the cold room.
The thought arrived at 03:09, halfway down a dead corridor, and it hit hard enough to fold her leg under her. Jade sat against the wall. The orb dimmed to a coal beside her ear, the way people lower their voices in hospitals.
The corridor had its own weather. Condensation beaded on the ceiling, fattened, and let go, tapping her hair, her neck, the back of her metal hand, cold every time. Somewhere far off a pipe groaned and went quiet.
For a while she did the practical things. She unrolled the blueprint across her thighs and measured the red line with her thumb, joint by alloy joint, the way she'd once clocked guard rotations. Four thumbs. Six hundred meters, maybe, and fifty-one minutes until the purge.
And under the counting, the other thing kept going. She kept hearing his knock, two raps and a pause and one more, at her door around midnight with a bag of noodles so loaded with chili that the steam made her eyes water before the lid came off. She'd kept a spare pair of his chopsticks in the drawer beside her own, and she hadn't been able to open that drawer since Cassin's message. If he was down here, she was going to break his nose. If he wasn't, she didn't know what she'd do with the hope, which had crept in without asking and now sat in her chest like a second heart, a stupider one than the machine they'd put there.
Then her mind slid off the hope and landed on the rabbit cup. On the chewed ear. On how she had known.
She put that thought down the way she'd put down a live wire.
Retired, she'd told Cassin. Retired, she'd told herself, every night for years, in a flat in the old sector where nobody looked twice at anyone. And here she sat in the station's guts, reeking of copper and frying oil, wanting that flat and its cracked mug so much it embarrassed her.
The orb brightened a notch. "Your breathing has changed."
"Mind your business."
"You are my business. It's in my programming, right next to 'avoid water.'"
"You were in a sock pile."
"I was between assignments."
Jade laughed, and it came out wrong, cracked down the middle. She wiped her face with the back of her wrist, metal cold against wet skin. Then she rolled the blueprint, tucked it in beside the shard, and stood on a knee that hated her.
03:13.
"Let's go see who's been signing his name."
"You didn't check the map," the orb said.
"Lucky guess."
Jade looked back at the fork she'd just taken. Left. She unrolled the blueprint to prove it to herself, and the red line went left, and her thumb followed it down to where it ended, on the S4.
The Architect's true eye awaits the Key of Four. In B's diner she had read that as four constants, the old operating math her parents used to whisper about in basements. Now a four sat under her thumb, printed on paper older than the Founding.
It could be nothing. Neo-Eden was full of fours. She rolled the blueprint up without saying anything else, and she didn't like how fast she did it.
Past the fork, something rolled out of an alcove and fell in behind her. A squat maintenance unit on rubber treads, a broom arm folded against its side, bumping at her heel like a dog that wanted to be let in. For fifty meters it followed her, whirring. Then it stopped, pointed its sensor stalk at her for a long moment, and trundled back the way it had come.
"It's decided you're not its problem," the orb said.
"Lucky me."
"I'm less certain."
The red line took her down a stairwell next. It wound around a hollow core twenty meters across, and the core was full of cables. Thousands of them hung from somewhere above her light and dropped past the railing into somewhere below it, gray and black and a few gone green.
When Jade breathed out, the nearest ones swayed. When she held her breath, they stopped. She tried it twice more to be sure, and then she stopped trying it.
"Air currents," the orb said.
"Sure."
Forty steps down, someone had hung a wind chime from the railing. Bent spoons, a bottle cap, a key with no teeth. The cables stirred, the spoons touched, and the sound carried a long way up and a long way down.
At the bottom, the stairs let out into a room she couldn't see the ends of. The orb brightened, and its light went out across the floor and didn't find a wall. It didn't find a ceiling either. Since B's diner, Jade didn't trust ceilings, and she didn't look up for long.
Somewhere in the dark, something big was pumping. A long push, a long pause, another long push, slow enough that she caught herself waiting for each one. She felt them come up through the soles of her boots.
She knew that sound. It was the hum, the one that ran under every street in Neo-Eden, the one you stopped hearing before you learned to talk. Up there it was a hum. Down here it was a beat, and for a few seconds she couldn't tell it from the synthetic pulse in her own chest. Against her hip, through the coat, Kensuke's gear-and-eye pendant had gone warm.
A channel ran along the left side of the path, a foot wide, carrying water. Steam came off it. She put two fingers in, and her sensors read thirty-eight degrees, warm as a bath someone had just gotten out of.
A paper boat came by on the current. Someone had folded it from a food wrapper, and it turned once in the steam and went on past her into the dark. She watched it until she couldn't.
Her implant kept labeling things. UNKNOWN. UNKNOWN. UNKNOWN INDUSTRIAL SYSTEM. After a while she turned the labels off, and the room got bigger.
The path followed the channel. Every thirty meters a caged bulb burned on a post, and most of them worked. Under one of them, on a ledge, someone had planted a tomato in an upturned safety helmet.
It had four small green tomatoes and one going orange. Jade touched the soil. It was damp.
She stood there longer than made sense, looking at the orange one. Someone had carried dirt down here. Someone came by with a cup of water, maybe every day, maybe on the way to somewhere. Behind her the pump pushed and paused and pushed.
Then a hatch, and taped to the hatch a sheet of paper in a plastic sleeve, lettered in marker.
QUIET HOURS 22:00 TO 06:00. THIS MEANS YOU, DEZ.
Jade read it twice. Her chronometer pinged 03:21. When she stepped through the hatch, she found she was doing it on the balls of her feet, the way you do in a house where people are asleep.
In the next alcove lay a sleeping bag. Green, unzipped, the fabric pressed into the shape of a body that had lain curled on its side. Jade crouched and slid her hand inside. Her fingers couldn't feel warmth the way skin did; they reported it. Thirty-six degrees.
"Keep moving," the orb said.
She didn't. She stayed crouched with her hand in a stranger's warmth, looking at the dent, at where the hip had been and where the shoulder had been, trying to guess how tall they were. Nothing came out of the dark. Somewhere ahead, water dripped.
"Jade."
She stood.
The chanting came from around the bend.
Jade killed the orb's light with one hand and pressed herself into the recess between two conduits. The metal was cold through her coat. Below her, the pump pushed and paused and pushed, but the voices were closer than the pump.
One voice became three. Three became ten.
They came around the corner in single file, hooded, and Jade's chronometer pinged 03:24 inside her skull loud enough that she was sure they heard it. Nobody turned. They kept coming.
Men and women, though she couldn't always tell which. Their clothes didn't match. Some wore old maintenance coveralls and some wore robes stitched from insulation fabric, and one wore a hospital gown under a yellow raincoat.
All of them were barefoot.
Their heads were bowed and their hands hung folded in front of them. The chant was too low for words. Every few steps one of them reached out and touched two fingers to the wall, the way you'd touch a railing on a boat to make sure it was still there.
The first man passed close enough that she could have tripped him. Jade looked at his feet, because feet were what she always looked at first, and saw blue fibers stuck to the wet soles. Industrial blue. The carpet in the break room.
She stopped breathing.
He went past. Another followed, then another. Twenty of them. Thirty. Their bare feet made almost no sound on the concrete, and the chant changed as they walked, and Jade caught three words of it.
"Below. Within. Below."
There was something wrong with the way they moved. They weren't in step. It was worse than that. Each of them seemed to be following the same instruction while pretending to have a body of their own.
One woman stopped.
Jade's hand closed on her pistol. The woman's head turned toward the recess, and she looked straight at Jade.
Her face was ordinary. Tired, middle-aged, a small scar under one eye. She might have been somebody's mother, somebody who circled birthdays on a calendar and wrote cake next to them.
Her mouth kept moving with the others. Her eyes had nobody behind them.
Then, under the chant, so low Jade almost missed it, she said something that wasn't part of it.
"Don't wake it."
And she walked on.
Jade stayed in the recess after the last hood went around the bend. Ten seconds. Twenty. The chanting thinned into the noise of the machinery until she couldn't tell whether it was still there.
Something had taken the room inside those people where a person was supposed to be. She didn't know what, and she didn't want the word for it yet.
"How many?" the orb whispered.
Jade looked at the empty corridor. "Too many."
She stepped out of the recess. Far below, something answered with a single deep thump that she felt in her teeth, and around the bend, the chanting started again.
Four minutes later, the chanting was gone.
Past the next turn, faint as a neighbor's television through a wall, a radio was playing. She knew the song. She couldn't place it, and that bothered her more than the sleeping bag had.
Then came the bleach.
Not the rust smell of the upper tunnels. Clean and chemical, like a bathroom scrubbed for company. Ahead the walls ran seamless and pale, and floor strips lit under her boots one panel at a time and went dark again behind her.
Her boots squeaked. After an hour of slime and grit the sound was obscene, and it bounced down the corridor and came back to her like someone else's footsteps. She stopped. The echo took one step more.
Then it stopped too.
Halfway down, a maintenance tag hung from a conduit at shoulder height. Paper, crisp enough to crackle. Jade lifted it with one finger.
SEAL INSPECTED. PRESSURE NOMINAL. Today's date. 03:02.
And where an inspector's name belonged, someone had written sixteen characters in careful block print. A prefix, a date string, a checksum. The same pattern again, and it belonged neither to the old man's wrist nor to the shard in her pocket.
How many people were down here tonight? And why did whoever swept these floors sign their work with numbers instead of a name?
The corridor ended at a door.
It filled the passage wall to wall, dull gray steel with no hinges she could see and no seam she could get a blade into. Cold came off it. She could feel it on her face from three steps away.
A panel slid open beside it. Behind scratched glass sat a keypad, sixteen physical keys, and a single red light blinking above them. Her chronometer pinged 03:31. Twenty-nine minutes to the purge.
Behind her, the radio swelled, and she placed the song.
Her fingers moved without a tremor. They were alloy now, and alloy didn't shake. Kensuke had taught her the steadiness back when her hands were still her own, in a noodle shop on Ring Six with a cheap padlock and a bent hairpin, while a radio on the counter played this same song about harbors. Hands don't know you're scared, he'd said, so don't tell them. She was telling them now, and they went on keying the sixteen characters from the shard's spine anyway.
The red light blinked. Held. Blinked.
Then, on the far side of the steel, something knocked.
Two raps.
A pause.
Jade knew that pause. She had been listening for it since Cassin's message. Don't wake it, the woman had said, and Jade's fist was already rising toward the steel when the third knock came.
