The Kia arrived at Null Motorworks at 2:13 in the morning.
Elias knew the exact time because every camera, computer and electronic lock in the building synchronized with the same internal server.
He was alone at his workbench, examining an ignition map from a damaged Genesis Coupe, when three heavy knocks struck the steel entrance door.
Nobody with an appointment came at two in the morning.
Elias closed the map and looked toward the security monitor.
A young woman stood outside beneath the yellow loading-dock light. Rain ran from her hood onto her face. Behind her sat a white Hyundai Veloster Turbo with its engine running unevenly.
The headlights flickered.
Then the engine stopped.
Elias opened the door halfway.
โWeโre closed.โ
โI know.โ
โThen you understand the problem.โ
The woman looked back at the Veloster.
โMy car doesnโt.โ
Elias remained silent.
She removed a small black module from her jacket and held it out.
It was an ECU.
โI was told you could read things other people couldnโt.โ
โThat depends on who told you.โ
โHe said you would ask that.โ
โWho?โ
The woman looked past him into the dark shop.
โHeโs dead.โ
Elias opened the door.
Her name was Mira Han. She claimed the Veloster had belonged to her older brother, Daniel, an electrical engineer who had died in a warehouse fire six months earlier.
The police had ruled the fire accidental.
Mira had never believed them.
For several months, the Veloster had remained locked inside Danielโs garage. The battery was disconnected, the keys were stored in a drawer and nobody touched the car.
Then, three nights ago, the engine started by itself.
Elias studied her expression.
โRemote starter?โ
โIt doesnโt have one.โ
โAftermarket alarm?โ
โNo.โ
โConnected battery maintainer?โ
โNo.โ
โSomeone entered the garage.โ
โThe security camera shows nobody going inside.โ
Elias turned toward the car.
โAnd you drove it here?โ
โIt told me to.โ
For the first time, Elias appeared interested.
Mira handed him her phone.
A message had appeared on the Velosterโs small dashboard display after she reconnected the battery.
TAKE ME TO NULL.
Elias brought the car inside.
The Veloster looked nearly stock. Factory wheels. Factory exhaust. No visible engine modifications. But beneath the passenger seat, he found a second wiring harness leading toward the centre console.
Someone had installed additional hardware inside the car and taken extraordinary care to conceal it.
Elias connected Mara to the diagnostic port.
The laptop displayed the vehicle information.
Then it froze.
The screen went black.
A new line of white text appeared.
HELLO, ELIAS.
Mira stepped closer.
โYouโve seen this before.โ
โNo.โ
โYou donโt look surprised.โ
โI try not to reward software for being dramatic.โ
He disconnected the laptop.
The message remained on the screen.
That was impossible. Mara was no longer physically connected to the vehicle.
Elias turned toward Cipher.
Across the workshop, the Forte Koupโs dashboard illuminated.
Its engine was not running.
The custom display above the dashboard produced a single warning:
UNAUTHORIZED NETWORK HANDSHAKE
The Veloster had contacted Cipher wirelessly.
Elias immediately shut down the shopโs external network. Steel shutters descended across the windows. The security system isolated itself from the internet.
For the next three hours, Elias removed the Velosterโs interior panels, traced the hidden wiring and documented every component.
Beneath the dashboard, he discovered a custom controller connected directly to the carโs communication network.
It was not designed to increase power.
It was designed to listen.
The device had recorded thousands of hours of vehicle dataโnot only from the Veloster, but from other cars it had encountered. Sensor messages. Diagnostic sessions. Key authentications. Wireless identifiers.
The car had been collecting digital fingerprints.
Mira watched Elias scroll through the files.
โWhat was my brother building?โ
โI donโt know yet.โ
โYou always say that?โ
โOnly when I donโt know.โ
One file was larger than the others.
Elias opened it.
A map of Toronto appeared. Hundreds of small points covered the city, each representing a vehicle the device had communicated with.
Most were ordinary encounters.
One point was different.
It appeared repeatedly at the same abandoned industrial property where Daniel had died.
Elias selected it.
The file contained the identity of another vehicle, but the manufacturer and model fields had been deliberately erased.
Only one piece of information remained.
A calibration signature.
Elias stared at the hexadecimal sequence.
He recognized it.
It was part of a control strategy he had written years earlier while working in industrial softwareโa method that was never supposed to leave the companyโs secure development system.
Mira noticed the change in his face.
โWhat does it mean?โ
โIt means your brother found something.โ
โWhat?โ
โSomeone adapted my old code to control a car.โ
โCan you tell which car?โ
โNot from this file.โ
The Velosterโs headlights suddenly switched on.
Its starter engaged.
The engine fired and immediately climbed toward redline.
Elias reached through the open window and turned the ignition off.
Nothing happened.
The engine continued screaming.
He pulled the fuel-pump fuse.
The engine stumbled and died.
Silence filled the workshop.
Smoke drifted from the exhaust.
On Maraโs screen, another message appeared.
STOP LOOKING.
Mira stared at Elias.
โWhat happens now?โ
Elias placed the Velosterโs ECU inside an anti-static container and locked it.
Then he walked toward Cipher.
The Forte Koupโs headlights awakened as he approached.
โWe find the car your brother was following.โ
โAnd then?โ
Elias opened the driverโs door.
โThen we ask its ECU why someone was willing to kill for it.โ
Outside, the rain had stopped.
Somewhere beyond the closed shutters, an engine started.
It remained there for several seconds, idling in the darkness.
Then it accelerated away.
Elias looked toward the sound.
For less than a second, the security monitor captured the departing car.
Low roof.
Wide rear fenders.
Four red taillights disappearing around the corner.
The image distorted before the licence plate became visible.
Cipherโs dashboard displayed a final message:
CALIBRATION SIGNATURE DETECTED
Elias started the engine.
The bronze wheels began to turn.
The hunt had begun.
