THE LAST CAR / Chapter 2 / 10

Chapter 2 - The Man Behind the Door

Nadia did not run back to Anton.

Running would tell everyone she was afraid.

More importantly, it would tell the traitor where her fear lived.

She handed Evan Shaw the radio.

“Lock this door.”

He blinked.

“You’re going forward?”

“Yes.”

Laura grabbed Nadia’s arm.

“Your son is behind us.”

“I know.”

“One of four people has the encryption key, and Pavel is one of them.”

“I know.”

“You’re leaving Anton with him.”

Nadia looked at her.

“If Pavel wanted Anton dead, he had thirteen years.”

“That does not mean he is innocent.”

“No.”

“What does it mean?”

“It means panic is not evidence.”

Laura released her.

Nadia wished she believed the sentence as confidently as she had said it.

She called the last car on Anton’s phone.

No answer.

Again.

Nothing.

Her throat tightened.

Then Anton’s voice came through the radio in Shaw’s hand.

“Mom?”

Nadia took it so fast Shaw almost dropped it.

“Why didn’t you answer the phone?”

“Because Pavel made me turn off Wi-Fi.”

Nadia closed her eyes.

“Why?”

Pavel’s voice answered in the background.

“Because someone connected to his phone remotely.”

Nadia looked at Anton’s device in her hand.

The screen flashed once.

Then went black.

Laura whispered, “Clone.”

Nadia pressed the radio.

“Pavel, what did you see?”

“A remote management prompt. Same certificate family our office uses.”

“Could you tell whose?”

“No.”

“Can you move?”

“I thought I was medically excellent.”

“Can you move?”

“Yes.”

“Take the children into the rear service compartment. Lock both doors. No networked devices.”

Anton cut in.

“Mom, Clara’s tablet is already off.”

“Good.”

“And I pulled the battery from the service phone.”

Nadia looked at Laura.

Laura almost smiled.

Nadia said, “Good.”

Anton hesitated.

“Are you coming back?”

Nadia stared toward car nine.

“Yes.”

This time she refused to make it sound like a promise she could break.

She lowered the radio.

Shaw said, “If the override is in nine, we have maybe twelve minutes before the freight crossing.”

“Then stop counting aloud.”

They moved forward.

Car nine was dark.

The emergency lights had been smashed.

Nadia smelled hot plastic and brake dust.

A portable control unit had been bolted to the wall beside the service cabinet. Three cables disappeared into the train’s communication panel.

Laura whispered, “Can you disconnect it?”

Shaw shook his head.

“Not while we’re moving this fast. If it’s spoofing signal data, cutting it could lock the brakes or release them. I need to see the interface.”

Nadia crouched beside him.

The small screen required a passcode.

Fourteen characters.

Volkov corporate format.

Shaw looked at her.

“Can you open it?”

“Maybe.”

“Maybe is better than no.”

Nadia entered an emergency audit credential.

ACCESS DENIED.

She entered Sergei’s executive credential.

ACCESS DENIED.

Laura watched the corridor.

Nadia tried the legacy disaster-recovery key.

The screen opened.

Shaw exhaled.

“You keep old keys active?”

“No.”

Nadia stared at the display.

Someone had reactivated one.

A key Nadia had retired eleven years earlier.

A key created by her husband, Mikhail.

Her dead husband.

She felt the floor move beneath her even though the train had not changed speed.

Laura saw her face.

“What?”

Nadia pointed at the key identifier.

M.VOLKOV-PRIMARY.

“Mikhail,” she said.

“Your husband?”

“Yes.”

“I thought he was dead.”

“He is.”

Shaw glanced between them.

“How dead?”

Nadia looked at him.

“Funeral. Body. Autopsy. Very dead.”

“Understood.”

The screen showed remote routing commands originating from an external satellite relay and authenticated through Mikhail’s old credential.

Nadia scrolled.

There were also manual commands from inside the train.

Car nine.

Car six.

Engine.

Someone on board had repeatedly coordinated with the outside controller.

Shaw said, “Can we trace the internal device?”

Nadia opened the session log.

DEVICE ID: VLK-P3.

Her mouth went dry.

P3.

Pavel’s original executive phone.

The one he had used for almost a decade.

The one he claimed had been destroyed after a security breach two years earlier.

Laura read her expression again.

“Pavel?”

Nadia said nothing.

Shaw swore quietly.

The connecting door behind them opened.

All three spun.

Sergei stood there.

His coat was torn. Blood ran from a cut across his forehead. He carried no visible weapon.

Nadia raised hers anyway.

“Hands.”

Sergei stopped.

“Sister.”

“Hands.”

He lifted them.

Laura moved behind a seat.

Shaw kept his pistol aimed.

Sergei looked at the control unit.

“You found it.”

“You said you were in the engine.”

“I was.”

“That is four cars away.”

“I walked.”

“Through armed men?”

“Some were occupied.”

“With what?”

“Bleeding.”

Nadia almost smiled.

Almost.

Then she pointed at the device ID.

“Explain that.”

Sergei leaned closer without lowering his hands.

His face changed.

“Pavel’s old phone.”

“Yes.”

“He destroyed it.”

“He said he did.”

Sergei looked toward the rear cars.

“Anton.”

“Is alive.”

“For now.”

Nadia’s eyes hardened.

“Be careful.”

Sergei met her gaze.

“I meant Pavel may not be the person using the device.”

“Why?”

“Because I was there when he destroyed it.”

Nadia paused.

Sergei continued.

“We were at the Newark warehouse after the breach. He smashed it, drilled the storage module, and threw the pieces into the furnace.”

“You remember that clearly?”

“I helped.”

“Why didn’t I know?”

“Because you were in the hospital with Anton.”

The memory hit her.

Anton had been ten.

Appendicitis.

Three days of Nadia sleeping in a chair beside his bed and pretending the Volkov organization could run without her.

Pavel had called the breach routine.

Sergei had agreed.

They had protected her from business for seventy-two hours.

At the time she had been grateful.

Now she hated them for it.

Shaw said, “Device IDs can be cloned.”

“Yes,” Nadia said.

Laura looked at Sergei.

“Can old credentials be cloned too?”

Sergei glanced at Mikhail’s identifier.

His face lost color.

“No.”

Nadia watched him carefully.

“Why not?”

“Mikhail’s primary key was hardware bound.”

Shaw frowned.

“Meaning?”

“Meaning the original cryptographic token had to exist somewhere.”

Nadia shook her head.

“It was destroyed after his death.”

“By who?” Laura asked.

Nadia answered automatically.

“Irina.”

Silence.

Sergei lowered his hands slightly.

“Irina Markov.”

Nadia looked at him.

Their chief accountant.

The fourth person with access to current keys.

The woman supposedly in Moscow.

The woman who had handled the shutdown of Mikhail’s credentials eleven years earlier.

Laura said, “So she could have kept the token.”

“Yes,” Nadia said.

Sergei’s jaw tightened.

“And she could have created the current key copy too.”

Nadia looked back at the log.

The betrayal had a shape now.

Not certainty.

But shape.

“Where is Irina?” she asked.

Sergei stared at her.

“Moscow.”

“No. Where is she?”

He hesitated.

Nadia’s voice dropped.

“Sergei.”

He looked away.

“New York.”

Laura whispered, “Of course.”

Nadia felt anger arrive with almost physical heat.

“You knew she came back.”

“She called me yesterday.”

“And you did not tell me.”

“She said she found irregularities in the port accounts.”

“The human cargo?”

“She did not say that.”

“What did she say?”

“That our father’s old government routes were active again.”

Nadia stared.

Their father had died fourteen years earlier.

Mikhail had inherited the organization.

After Mikhail’s death, Nadia had inherited what remained.

She had spent eleven years rewriting rules, closing routes, cutting off men who enjoyed violence too much.

And all that time, someone had been using the dead infrastructure beneath her living empire.

Shaw tapped the control screen.

“We have eight minutes.”

Nadia forced herself back to the train.

“What can you do?”

“If I can authenticate a local reset, I can return brake control to the engineer.”

“Do it.”

“I need a valid current Volkov credential because the malicious system is blocking standard rail authorization.”

Sergei reached inside his coat.

Nadia raised the gun.

“Slowly.”

He pulled out a metal key fob.

“My executive token.”

Nadia stared at it.

“You still carry that?”

“You taught me paranoia.”

“I taught you competence.”

“Same thing with better tailoring.”

Shaw took the token.

The screen accepted it.

RESET AVAILABLE.

Then a second prompt appeared.

DUAL AUTHORIZATION REQUIRED.

Nadia laughed once without humor.

“Mikhail built that.”

Sergei looked at her.

“Two executives for critical routing changes.”

Nadia removed a thin silver pendant from beneath her blouse.

Laura blinked.

“That is your second token?”

“It is ugly jewelry.”

She pressed it to the reader.

AUTHORIZATION ACCEPTED.

Shaw reached for RESET.

The screen changed.

REMOTE LOCKOUT ACTIVE.

A countdown appeared.

06:32.

Sergei swore.

Shaw said, “The external controller has final authority.”

Nadia asked, “Can we kill the satellite link?”

“Not from here.”

Sergei looked toward the roof.

“The train antenna.”

Shaw nodded slowly.

“Roof access is in car seven.”

Laura said, “We are in nine.”

Nadia holstered her weapon.

“Then we walk.”

The radio crackled again.

Kessler’s voice.

“Nadia, you’re making this unnecessarily difficult.”

She took the radio from Shaw.

“No. Difficult was when I thought I had one traitor.”

Silence.

Nadia continued.

“Tell Irina I found Mikhail’s key.”

For the first time, Kessler did not answer immediately.

Sergei looked at Nadia.

Laura smiled faintly.

There it was.

Not proof.

But fear.

Kessler finally said, “You should have left the dead alone.”

Nadia looked at the countdown.

05:58.

She pressed transmit.

“You first.”

Then she handed the radio back to Shaw and moved toward car eight.

Behind her, Sergei asked, “Was that the plan?”

“No.”

“What is the plan?”

May you like

Nadia opened the door.

“To survive long enough to make one.”
