Rain had been falling over Valis for six hours, though from the forty ninth floor it looked less like rain than static.
Orren Vale sat beneath a brass work lamp with his sleeves pushed to the elbows and a loupe fixed over his right eye. Beyond the glass, the city went on performing its nightly imitation of permanence. Towers climbed through the weather. Transit lines burned white between them. Somewhere above the clouds, freight was being exchanged between Earth and machines that had never touched soil.
He ignored all of it.
On the table lay thirty seven pieces of a machine no government registry knew existed.
He had counted them twice.
Not from nervousness. Orren was rarely nervous.
He counted things because numbers were less likely than people to become confused about what they were.
The main housing lay beneath the lamp. At first glance it resembled blackened steel, though there was almost no iron in it. The shell was a ceramic carbon composite wrapped around a conductive lattice whose purpose was to move heat inward rather than release it into the room.
Heat had become incriminating.
So had sound, pressure, gait, breath and, in certain districts, hesitation.
The old detective stories had imagined a future in which criminals would be defeated by cameras.
They had underestimated mankind's appetite for measurement.
The modern city did not merely watch you. It inferred you.
A sudden rise in room temperature, the ionization of air, an acoustic impulse reflected from three buildings, a human figure departing twelve seconds later at an elevated heart rate. None of these facts meant much separately. Together they became a story.
Orren had been paid to make the story difficult to tell.
He rotated the housing beneath the lamp.
The weave was clean.
He ran a thumbnail along the interior lip and felt no deformation.
Good.
He set it down beside the firing assembly and took a drink of coffee gone cold.
There had been a time when men working late at benches drank whiskey. He knew this because films had survived longer than most of the customs they depicted.
Orren preferred coffee.
Whiskey made incompetence feel philosophical.
The commission had arrived nine days earlier.
No introduction. No name. No attempt at charm.
He appreciated that.
There were specifications.
Mass below four kilograms.
Operable in vacuum.
No network dependency.
No persistent telemetry.
No manufacturer authentication.
No cloud diagnostics.
No record of discharge.
The last requirement interested him.
He read it again.
Then a third time.
No record of discharge.
That was difficult.
Difficult was increasingly rare.
Modern engineering had become the art of assembling things someone else had already solved. Components arrived certified. Software corrected mistakes. Fabricators compensated for poor tolerances. Machines watched other machines until the person operating them became little more than legal responsibility attached to the process.
Orren had spent most of his life removing those conveniences.
Convenience, he had concluded, was merely dependence that had learned good manners.
He accepted the commission.
The money was substantial, although money was no longer the reason he worked.
At twenty, he had wanted money.
At thirty, freedom.
At forty, competence.
Now he mostly wanted to be left alone with difficult things.
The logic unit was next.
Most weapons built in the last twenty years contained more computing power than the first lunar colonies. They identified faces, corrected for atmosphere, predicted movement, logged maintenance, verified ammunition and politely informed several distant companies of their condition.
Orren's machine would do almost none of that.
Its processor was optical, hardened and deliberately stupid.
Thirty year old architecture.
No adaptive model.
No wireless stack.
No operating environment large enough to hide surprises in.
If it had thoughts at all, they amounted to yes, no, ready and stop.
Orren trusted machines more as their vocabulary diminished.
He fitted the logic block into the housing.
There was resistance halfway down.
He stopped.
Removed it.
Looked again.
A fragment of composite fiber, barely visible, had caught along the guide.
He removed it with tweezers.
Tried again.
This time the block settled into place with a small metallic click.
Orren smiled.
There were engineers who spent enormous effort eliminating such sounds.
He regarded this as vanity.
A click was information.
Resistance was information.
Weight was information.
A machine that spoke through the hand rarely needed to explain itself on a screen.
His father had taught him that.
Or perhaps he had taught himself and assigned the lesson to his father afterward. Memory was unreliable in that way.
There had been a workshop once, outside Novi Sad, before the second Adriatic expansion moved the coast north and the maps became temporary documents.
His father repaired agricultural engines.
Orren remembered the smell of cutting oil, hot metal and dust.
He remembered being given a torque wrench at eleven.
He remembered the old man standing behind him.
Feel it.
That was all.
Not a lecture.
Not a principle.
Feel it.
Orren still did.
The lights dimmed.
His hands stopped.
The reduction was slight.
Perhaps five percent.
Enough.
He looked toward the ceiling.
The building regulator had compensated for an unexpected load.
The apartment was supposedly empty.
So were most of the others on the floor.
Orren reached beneath the bench and switched off the work lamp.
Darkness folded over him.
The city remained visible through the window, huge and indifferent.
He waited.
There.
A vibration through the floor.
Elevator.
Beside the door stood an analog meter he had assembled from an induction coil, a needle gauge and several components manufactured before Orren was born.
It had no firmware.
No address.
Nothing to hack.
The elevator's motor produced a field. The building's shielding reduced it but did not abolish Maxwell's equations.
Old physics had become useful again.
The needle moved.
Forty three.
Forty four.
Forty five.
Orren watched.
Forty seven.
It stopped.
Two floors below.
Perhaps a delivery.
Perhaps maintenance.
Perhaps three men carrying compact weapons and legal authorization to erase the apartment from municipal memory after they finished with him.
The trouble with paranoia was that occasionally it was simply pattern recognition arriving early.
Orren stood.
The machine was not finished.
This irritated him.
He packed the receiver housing, logic block and thermal assembly into a canvas satchel. He left twenty thousand credits' worth of components on the bench.
None mattered.
The design existed in his head.
Everything else was inventory.
The elevator began moving again.
Forty eight.
Orren walked into the kitchen.
Beside the refrigerator was a plumbing access panel.
He had removed its factory fasteners during his first night in the apartment and replaced them with magnetic catches.
Behind it ran a service shaft.
He slipped inside and pulled the panel closed.
The space smelled of concrete dust and warm pipes.
Above him came a concussion.
The apartment door.
Another.
The third broke something structural.
Orren began climbing down.
Slowly.
Speed produced noise.
Noise produced information.
He passed the forty eighth floor.
Then the forty seventh.
Above him, men entered a room containing enough evidence to make them confident they understood what had happened there.
Confidence was useful.
Especially someone else's.
On forty six, Orren pushed through another maintenance panel into an apartment without electricity.
A coat hung from a chair.
Shoes waited beneath it.
A cheap cap.
On the counter lay a transit card registered to a seventeen year old visitor from Luna who had returned home seven months earlier.
Orren changed.
He placed his old clothes inside a disposal sack and fed them into the building's organic recycler.
The machine paused for half a second while deciding whether his jacket had ever been alive.
Then it accepted it.
Orren took the stairs.
By the time the men upstairs discovered the service shaft, he was standing beneath the transit canopy with several hundred commuters.
Rain struck the transparent roof overhead.
A woman beside him was arguing quietly with an artificial voice inside her glasses.
Two construction workers discussed orbital hazard pay.
A child stared at Orren and then at something more interesting behind him.
Perfect.
He boarded a westbound carriage.
Nobody followed.
That did not mean nobody was following.
It merely meant he had not found them yet.
He slept that night in a capsule hotel near the industrial harbor.
At 04:10 he woke.
No alarm.
At 04:21 the contract terminal received a message.
STATUS REQUESTED.
Orren stared at it.
The channel was correct.
Encryption intact.
The problem was not the message.
The problem was that the client had sent one.
Their agreement had been explicit.
No communication until completion.
Either the client had become careless or someone else had learned the protocol.
Orren considered both possibilities.
He preferred neither.
He deleted the message.
Then opened the terminal.
Removed its storage wafer.
Placed the wafer between two steel spoons.
Pressed.
The wafer cracked with surprising elegance.
He fed the fragments into the hotel's wastewater reclamation port.
The next morning, he ate eggs beside the harbor while autonomous cranes unloaded a helium freighter from Shackleton.
The contract was compromised.
Therefore the rational decision was to abandon it.
Orren finished his eggs.
Watched a crane lift four hundred tonnes of cargo as casually as a man picking up luggage.
Ordered another coffee.
The rational decision remained unchanged.
He found this annoying.
He could abandon the client.
He could abandon the money.
He could even abandon his reputation, which was useful only insofar as it attracted more people who wanted things from him.
But the machine remained unfinished.
That was harder.
There was a form inside it he had not yet reached.
An answer.
Not metaphorically. Orren disliked turning engineering into religion.
There simply existed a configuration of mass, heat, tolerance and force that would satisfy the problem better than the others.
He wanted to know what it was.
Civilizations had probably begun for equally foolish reasons.
Somebody had wanted to know what lay beyond a river.
Somebody else had wanted to see whether copper and tin behaved differently together.
Eventually there were empires, taxation departments and men kicking down apartment doors.
Progress was untidy.
Orren drank his coffee.
Then found another workshop.
This one occupied a maintenance room beneath an abandoned monorail station.
It had concrete walls, independent power and no window.
Excellent.
For eleven days he worked.
He changed sleeping locations every night.
He never carried more than three critical components at once.
Anything that could be purchased with cash was purchased with cash.
Anything that could not be purchased with cash was acquired through intermediaries who never understood what they had supplied.
He walked when possible.
He took public transit when walking became distinctive.
Three times he believed someone was following him.
Twice he was wrong.
The third time he spent four hours crossing the freight district before concluding that being wrong was not yet safe enough.
He returned to the workshop shortly after midnight.
The final assembly took two hours and thirteen minutes.
At the end of it, Orren placed the machine beneath the lamp.
It was smaller than he had imagined.
This pleased him.
Bad engineering often announced itself through size.
The exterior was matte charcoal, interrupted only where mechanical necessity required another material. No branding. No serial plate. No manufacturer mark.
Nobody had manufactured it.
Not really.
Companies had produced its substances.
Machines had produced its components.
Orren had produced the object.
There was a difference.
He lifted it.
Balanced it between his hands.
Shifted his grip.
The mass settled naturally.
He closed his eyes.
There.
His father again.
Feel it.
Orren opened his eyes.
He checked the internal systems.
Mechanical first.
Then optical.
Then thermal.
One amber light appeared near the rear housing.
No animation.
No logo.
No cheerful electronic greeting.
One light.
Ready.
Orren sat very still.
Outside the concrete room, pumps moved groundwater beneath the city. Trains passed occasionally through active tunnels half a kilometer away. Above all of that, twelve million people were waking, sleeping, buying, lying, mating, arguing, praying and producing information.
The city swallowed every gesture.
This object would give it almost nothing.
Orren found that beautiful.
Not the weapon.
Beauty was too easily assigned to dangerous things by men who wished to excuse their fascination with them.
The restraint was beautiful.
A machine that did only what had been asked of it.
Nothing more.
At 03:02 he opened a clean terminal and transmitted a single line.
COMMISSION COMPLETE.
The answer came eleven seconds later.
Coordinates.
Delivery procedure.
Payment authorization.
Then:
DO NOT ATTEMPT TO IDENTIFY THE USER.
Orren read the sentence.
He leaned back.
For perhaps five seconds he said nothing.
Then he laughed.
It was not much of a laugh, but the room had not heard one in years.
As if he cared.
He closed the terminal and killed its power.
For a while he remained at the bench, looking at the machine he had spent nearly three weeks designing, building, hiding and occasionally bleeding over.
Tomorrow it would belong to someone else.
It would acquire a history.
That was inevitable.
Objects were innocent only briefly.
People gave them names, purposes, enemies, legends.
Eventually historians came along and pretended the result had been necessary.
Orren had no interest in any of that.
He switched off the lamp.
The amber indicator disappeared.
Darkness.
He lifted the case from the bench.
The client could have his machine.
Orren had already taken the only part of the commission he wanted.
The problem.
