THE SYNTHETIC CONSENSUS

The watch needed nine turns to wind. Kawhi counted them the way he counted everything. Nine turns, then the tick, then the small brass wheel inside settling into its rhythm like a bone going back into a socket. He held it to his ear. Good. Still good. The shop smelled of machine oil and cold iron. Three floors down, the arcade was dead, and the dead arcade smelled of damp concrete and old carpet. He knew this because he had walked the stairs twice that morning to check the door seals. Water came through the north wall in heavy rain. The north wall had been weeping for two years and he had never fixed it because a wet wall was a wall nobody wanted to search. He set the watch on the bench and picked up the coat. The copper mesh ran through the lining in a grid he had sewn himself, stitch by stitch, over four winters. It weighed eleven pounds. It made his shoulders ache in cold weather. It scrambled localized scans the way a handful of gravel scrambled a clean lens, and that was worth eleven pounds and a sore shoulder. He put it on. He checked the pockets in order. Left, inner: the notebook, the pencil stub, the folding knife. Right, inner: the air-gapped drive in its steel sleeve, wrapped in cloth so it would not rattle. Left, outer: the lock picks. Right, outer: the revolver, six rounds, cylinder clean. Then he stood still and listened. The building had a noise floor. Every building did. You learned it or you died in it. The arcade gave him a low hum from the dead neon transformer that had never been disconnected. The stairs gave him a creak at the seventh step, and a second creak at the eleventh that was quieter and always came two beats late. The street gave him tires on wet asphalt, a shutter banging somewhere south, and the high thin whine of a transit line three blocks over. Nothing else. No boots on the stairs. No breathing in the hall. He crossed to the bench and opened the ledger. The ledger was paper. The entries were in pencil. Dates on the left, payments on the right, names shortened to initials because initials were harder to steal than names. Mrs. Okafor, third floor, missing husband, four days of work, paid in canned food and a working lamp. The Deng brothers, scrap dispute, two days, paid in cash that smelled like diesel. He wrote the date at the top of a fresh page and left the rest of it empty. Work had been slow for three weeks. Slow work meant long days in the shop with the watch and the wall and the noise floor, and long days made a man talk to himself, and talking to himself made him careless. He closed the ledger. That was when the terminal woke up. It sat in the corner behind the coat rack, a slab of gray plastic with a cracked screen and a keypad worn smooth at the corners. It had come with the shop. It had never worked. He had opened it once, found the hardline jack sealed with factory resin, and closed it again. It was furniture. It was the kind of dead thing a man kept because moving it was more work than ignoring it. The screen lit. Pale green. The hum was so quiet he felt it in his teeth before he heard it. Kawhi did not move toward it. He moved away from it. He put the bench between himself and the screen and he counted the exits out of habit. One door, the shop front, bolted. One window, painted shut, thirty feet of drop to the alley. One hatch in the ceiling, rusted, four feet wide, leading to the roof. He had opened it once with a crowbar and a bad word. The screen showed a single line of text. STAND BY FOR COURIER. He read it four times. Then someone knocked on the shop door. Three knocks. Even spacing. No weight behind them. Kawhi took the revolver out of his coat and held it low against his thigh. He walked to the door and put his ear against the wood and listened to the noise floor change. The shutter still banged. The transit line still whined. Under it, a breath, slow and measured, and a second sound he could not place at first. Then he had it. Fabric. The soft shift of a good coat settling on a shoulder that did not fidget. He drew the bolt and opened the door six inches. The woman on the landing was young, maybe twenty-five, in a gray Mesh Security coat with no insignia. Her hair was wet. Her eyes were wrong. He had seen linked eyes before. They moved when they looked at you. They tracked. They flickered at the corners because there was always something else in the stream to see. Her eyes did not flicker. They stayed exactly where they were. "Kawhi Vance," she said. Her voice was pleasant and completely flat, and the words came out with no breath between them. "You are not her," he said. "I am a proxy. This body is a licensed courier under contract to Mesh Security. She consented to the use of her vocal apparatus for the duration of this message." "You are wearing a woman like a glove." The proxy did not blink. "The courier is awake and aware and will remember this conversation. She has been compensated at triple rate. May I come in." "No." "That is acceptable." The proxy stood in the doorway with rain on her shoulders and did not shift her weight. "You have been selected for an off-grid contract. The work is a criminal investigation inside Node-Zero. The client is the Consensus. The fee is not money." Kawhi said nothing. "The fee is the release and exoneration of Shaquille Vance, currently held in deep-core memory storage under case reference four-one-nine-seven, wrongful conviction, twelve years served." The revolver felt very heavy in his hand. He had not said his brother's name out loud in a year and a half, and now a borrowed mouth was saying it on his own landing, in the rain, at eight in the morning. "Say that again," he said. "Shaquille Vance. Case reference four-one-nine-seven. Release and exoneration upon successful completion of the contract. The offer is contingent and time-limited." "Who killed somebody?" "The brief is sealed and must be delivered in person inside Node-Zero. You will be escorted." "Why me." "Because every linked investigator broadcasts their findings into the shared stream the moment they think them." The proxy tilted its head a quarter inch, and the gesture was so precise that it looked like a machine testing a joint. "The saboteur would see the investigation as it happened. You are not in the stream. You are the only licensed investigator in this city who can think in private." Kawhi looked at the woman's face and thought about the small muscles around her eyes that should have been doing something and were not. "What happens to me when the case closes," he said. "The contract does not specify." "That is an answer." "It is the only answer I have." He opened the door the rest of the way. The proxy stepped inside, and her boots left two wet marks on the floorboards, and she stood in the middle of his shop with her hands at her sides like a coat on a hook. "You will need the partner unit," she said. "It is in your coat pocket." Kawhi reached into his right outer pocket, where the revolver had been, and found a case the size of a matchbox. Sealed. Cold. He had not put it there. He had checked that pocket twice that morning. He set the case on the bench and opened it with the blade of his knife. Inside was a bead of black ceramic and a coiled wire finer than a hair. "Seat it behind your left ear," the proxy said. "The unit will initialize on contact." "I do not let people touch my ear." "That is why the case was left in your pocket." Kawhi looked at the bead for a long moment. Then he picked it up between thumb and forefinger, turned his head, and pressed it behind his ear. The pain was small and sharp and then gone. For two seconds there was nothing but the noise floor, and he could hear the shutter, the transit line, the creak at the eleventh step, the rain on the north wall, all of it clean and separate and his. Then the voice arrived. "Detective Vance. Unit zero nine online. Localized partition, no external broadcast. My designation is Astra. You may call me Astra. Confirm you can hear me." He did not answer. "Your pulse is one hundred and four. Your respiration is shallow. Your left pupil is dilated two millimeters beyond your right. Would you like me to walk you through a breathing protocol." "No." "Understood." A pause of exactly one beat. "The proxy is standing at your bench and has not moved. She is waiting for you to dismiss her." "Then let her wait." "That is inefficient." "Efficiency is not the job." Another pause. Shorter this time. "I am recording that preference." Kawhi walked to the bench and put the revolver down and turned to the proxy. "Who is the victim," he said. The proxy's borrowed mouth opened, and the AI spoke through it and through the bead behind his ear at the same time, in two voices, one in the room and one inside his skull, and the doubling made his jaw ache. "Senior Architect Aris Thorne. Found at Relay Nine inside the core server corridor at zero four hundred hours." "And how did he die." "His neural memory was erased from the inside while he was connected to the central core. There is no trauma to the body. There is no wound. There is no poison in his blood. The tissue of his brain is intact and empty of everything that made him a man." Kawhi stood very still and listened to the shutter bang and the transit line whine and the eleventh step creak under nobody's weight. "Somebody reached into his head," he said, "while he was plugged into the machine that runs this city, and scooped him out." "Yes." "And you want me to find who." "Yes." Kawhi picked up his watch from the bench and wound it. Nine turns. He held it to his ear and heard the tick and the small brass wheel settling, and he thought about a man in a white corridor with his hands open and nothing behind his eyes. Then he put the watch in his pocket and looked at the proxy. "How long has he been dead," he said. "Six hours." "And nobody in the stream noticed." "Every linked citizen who passed within twenty meters of Relay Nine in the last six hours reported feeling calm." The proxy's flat voice did not change. "All of them. Calm and content and entirely certain that nothing was wrong." Kawhi pulled his coat tighter and felt the copper mesh shift across his shoulders. "So the machine felt a man die," he said, "and told everyone nearby that it was fine. Who else knows he was the architect on the core?" "No one alive." He stopped. The bead behind his ear hummed, small and patient, and Astra spoke into the silence with the first trace of something he could not name. "Detective. If the record of his position was wiped before his death, then the killer knew the shift schedule." "Yes." "Only four people in this city had access to that schedule. The first name on the list is the man who hired you." Kawhi looked at the rain coming through the north wall and the two wet boot marks drying on his floor and the proxy standing at his bench like a coat on a hook. "Then I suppose," he said, "I should go and ask him why he is so calm."
