The Hollow Crown
The server room on the fortieth floor smelled of ozone and decades-old dust. Racks of decommissioned hard drives lined the walls like tombstones, their indicator lights long dead. Marcus pressed Jace into the corner farthest from the door, behind a bulkhead that might stop a stray round if Grant’s men found them.
Sofia knelt beside their son, hands moving with a precision that belied her terror. She had unzipped the emergency kit from Victor’s belt—a thin medical pouch Marcus hadn’t known the man carried. Inside: a syringe, a vial of clear liquid, and a small adhesive patch.
“This is the null sequence,” she said, her voice steady in a way that made Marcus love her more than he thought possible. “Your father designed it. It mimics the receptor pattern the Blackthorn system uses to authenticate your genetic marker. When it’s in your bloodstream, the network will see you as unregistered. Invisible.”
Jace looked at the syringe. Then at Marcus. “Will it hurt?”
“For a second,” Marcus said. “Then you’ll be the most invisible boy in the world.”
Sofia swabbed the inside of Jace’s forearm. The boy flinched as the needle went in, but he didn’t cry. Marcus counted the seconds—seven until the plunger emptied, three more until Sofia withdrew and pressed a cotton ball to the site.
“Tape,” she said. Marcus handed her the roll from the kit. She wound it around his arm twice, securing the micro-injector flush against the skin. “The system scans every thirty minutes. When it does, it will find the null sequence and overwrite your profile. You’ll be a ghost.”
Jace touched the tape. “Like in the games Daddy plays?”
“Exactly like that,” Marcus said. He pulled his son into a rough hug, feeling the small ribs through the thin shirt. “You’re going to be fine. You just have to do exactly what Mama says.”
A crackle of static from the ceiling speakers made all three of them freeze.
Then Silas Blackthorn’s voice filled the room.
It was not the voice of a man who had lost control of his building. It was the voice of a patriarch addressing his congregation—warm, measured, absolute.
“Citizens of New Alexandria. I speak to you not as a CEO, but as a father.”
Marcus moved to the server room’s single window. The glass was frosted with age, but through the grime he could see the city below. Every public screen along the boulevard had flickered to the Blackthorn logo. The golden crown on a field of black.
“For seventy years, my family has protected this city. We have built its towers. We have kept its lights on. We have ensured that every child born under our banner has a future.”
Sofia rose and came to stand beside him. Her hand found his. He squeezed.
“Tonight, that future is threatened by a coward. A man who once called himself my ally—who now hides in my home, using his own son as a shield.”
Jace’s voice was small. “He’s talking about us.”
Marcus didn’t answer. He was watching the screens. On every one, Silas’s face had been replaced by a photograph. A security still from the lobby, three hours ago. Sofia, holding Jace’s hand. Marcus, a step behind. The angle was perfect—it made Jace’s face unmistakable.
“I have no quarrel with the child,” Silas continued. “He is innocent. But his father is not. Marcus Blackwood has stolen from this city. He has betrayed the trust this family placed in him. And he has chosen to run, rather than face the consequences of his actions.”
Sofia’s grip tightened. “He’s going to turn the city against us.”
“He already has,” Marcus said. “That’s not the play.”
On the screens, the photograph dissolved into a live feed of the executive bridge. Marcus knew it well—the glass-enclosed walkway that connected the main tower to the central server core, suspended forty stories above the atrium floor. It was the only route to the system core. It was also a shooting gallery.
“I am offering a reward,” Silas said. “Five million dollars to any citizen who delivers Marcus Blackwood to the main entrance of Blackthorn Tower. Alive. The child and the woman are to be unharmed.”
Marcus turned from the window. “That’s the play. He’s making this personal. Every security guard, every off-duty cop, every desperate idiot with a gun is going to be looking for us.”
“What about the executive bridge?” Sofia asked. “It’s the fastest route to the core.”
“It’s also the most exposed. Glass walls, no cover, motion sensors every ten feet. Security will have drones on it in minutes once we step out.”
“Then we don’t give them minutes.”
Marcus looked at his son. Jace had taken the tape off his arm and was pressing it back on, watching the bubble of the micro-injector shift under the skin. A seven-year-old being braver than most soldiers Marcus had known.
“I have an idea,” he said. “But you’re not going to like it.”
He explained it in thirty seconds. The plan was simple: the server room had a maintenance locker with three EMP grenades—leftover hardware from a decade-old security upgrade that Victor had mentioned in passing. Marcus would take them to the east wing, set them off in sequence. The electromagnetic pulse would fry every drone in a hundred-meter radius, blind the motion sensors, and scramble the camera feeds. It would also cripple the building’s internal network for exactly ninety seconds.
In that window, Sofia would lead Jace across the executive bridge.
“Ninety seconds,” Sofia repeated. “That’s not enough time.”
“It is if you don’t stop moving. Don’t look down. Don’t look back. Just run.”
“What if the drones aren’t disabled?”
“Then you drop and cover Jace. I’ll be right behind you.”
She searched his face. “You’re not coming with us.”
“I’m setting off the EMPs. That means I’m on the other side of the building. But I’ll meet you at the core entrance. I’ll find a way.”
“The core entrance is guarded.”
“Then I’ll unguard it.”
Jace walked over and stood between them. “Daddy, you promised you wouldn’t lie.”
Marcus knelt so he was eye-level with his son. “I’m not lying. I’m going to get to that door. And when I do, you and Mama are going to be there, and we’re going to walk in together and stop that bad man from hurting anyone else. Okay?”
Jace studied him for a long moment. Then he nodded.
“Okay.”
Marcus stood and pulled Sofia into a kiss that tasted like goodbye. “When you get to the door, don’t wait. If I’m not there, you get Jace inside and you barricade.”
“Marcus—”
“I’ll find you. I always do.”
He grabbed the three EMP grenades from the maintenance locker, checked their charges—still green—and slipped out the service door. The corridor was dark, lit only by emergency strips. He moved east, counting doors, listening for footsteps.
At the junction with the main east wing, he heard the hum of rotors.
Two drones, hovering at the far end of the hall. Their red sensors swept left, right, left. He pressed himself into a recessed doorway, watching. The drones were stationary. Guarding the approach to the bridge.
He armed the first grenade, counted to three, and rolled it down the corridor.
The EMP detonated with a silent thump of compressed air. The drones dropped like stones, their rotors seizing. The lights flickered and died. The corridor went black.
Marcus ran.
At the second junction, he armed the next grenade and tossed it through an open office door. Another thump. More lights dying. In the distance, he heard the shriek of alarms—the building’s fail-safes kicking in, switching to hardline backup. That was good. Hardline meant no wireless. No wireless meant no drones.
He reached the third junction. The bridge was visible now—a glass tube thirty meters long, suspended in open air. The city lights glittered through its transparent walls like a thousand watching eyes.
He armed the last grenade and held it.
On the other side of the building, the service door opened. Sofia stepped out, holding Jace’s hand. She paused at the entrance to the bridge, looking across the void. The glass floor reflected the city below.
Marcus pressed the detonator. The third EMP went off at his feet, and every screen in his vicinity went dark.
Sofia ran.
She pulled Jace onto the bridge, her heels clicking against the glass. The boy kept pace, his small legs pumping, his free hand pressed over the tape on his arm. They were halfway across when the emergency lights flickered back on.
Seventy seconds left.
Marcus sprinted toward the bridge’s opposite entrance. He could see the door now—the heavy steel door that led to the central server core. It was closed. Sealed. And standing in front of it, arms crossed, was Grant Blackthorn.
Sofia saw him too. She slowed, pulling Jace behind her.
Grant smiled. It was a thin, cold thing—nothing like his father’s practiced warmth. He was younger, sharper, dressed in a tactical vest with a sidearm holstered at his hip. He looked like a man who had been waiting for this exact moment.
“Forty-three seconds,” he said. “Impressive. Father said you were resourceful.”
Marcus reached the bridge entrance. He was twenty meters away. Fifteen. Ten.
“She’s not going anywhere,” Grant said, drawing the pistol and aiming it at Sofia. “Neither is the boy.”
Marcus stopped. “Let them go. This is between me and Silas.”
“No,” Grant said. “This is between me and everyone who ever underestimated me.” He gestured with the barrel of the gun. “You come any closer, I put a round through her knee. You think I’m bluffing?”
Sofia’s eyes met Marcus’s. She shook her head once. A warning.
Grant laughed. “Look at you. Two professionals, brought low by a seven-year-old. Do you know how long we’ve waited for a genetic match like his? The system was designed for direct neural authentication. Every other method leaves a signature. But his signature is clean. Untraceable. He’s the key to the entire network.”
Marcus took another step.
Grant fired.
The shot went wide, shattering a panel of glass behind Sofia. She didn’t flinch. But Jace did. He cried out, a sharp, frightened sound.
“Next one goes through her,” Grant said.
Marcus stopped.
The timer in his head ticked past sixty seconds. The network would be coming back online. Drones would be redeploying. They were out of time.
“What do you want?” Marcus asked.
“I want you to watch.” Grant stepped forward, closing the distance between himself and Sofia. She backed up, shielding Jace with her body. “I want you to see exactly what happens when you try to steal from the Blackthorn family.”
Grant shoves Sofia aside and grabs Jace by the arm. “Hello, little key,” he sneers, pressing a gun to the boy’s temple as he turns to Marcus. “Watch. Your. World. End.”
