The black Range Rover screeched to a halt outside a rusting, dilapidated auto factory in Queens. Dust kicked up into the night air.

Heidi reached under the driver's seat. She pulled out a Glock 19. She screwed the black suppressor onto the barrel with practiced, deadly efficiency and shoved the gun into her trench coat pocket.

She kicked the rusted side door open. The smell of old motor oil and damp concrete hit her face.

In the center of the massive, empty warehouse, a single yellow bulb swung from the ceiling.

Caleb and Seraphina were tied to metal chairs under the light. Caleb sat perfectly straight, his eyes cold and calculating. Seraphina's face was stained with tears, but she bit her lip to stay quiet. When she saw Heidi step out of the shadows, her eyes lit up.

Sitting on a stack of tires a few feet away was Bobbie Weeks. He was a heavy man with cheap tattoos covering his forearms. He took a drag from a cheap cigarette and laughed.

"You got guts, lady. Coming alone," Bobbie sneered.

Heidi stopped ten paces away. She looked at him like he was already a corpse. "Let them go."

Bobbie stood up. He pulled a switchblade from his pocket and flicked it open. He held the blade inches from Caleb's cheek.

"Fifty million in Bitcoin," Bobbie demanded, tapping a tablet on the barrel next to him. "Send it to this wallet, or the boy loses an eye."

Heidi didn't blink. A cruel, mocking smile touched her lips. "Do you really think you're smart?"

Bobbie frowned.

"You're a low-level thug from downtown," Heidi said, her voice echoing in the empty room. "Does your daughter, Brigette, know you're doing this? Or is she too busy playing a high-society whore at the Page estate?"

Bobbie's face went pale. His eyes darted around in panic. He didn't expect this rich doctor to know his true relationship with Brigette—a scandalous secret that could destroy her fake high-society persona.

Anger flushed his face red. "Shut your mouth!" he roared. He pressed the knife closer to Caleb. "I'm counting to three! One! Two-"

Heidi drew the Glock.

Pfft.

The suppressed gunshot was a dull thud.

The bullet tore straight through Bobbie's right wrist. Blood exploded into the air.

Bobbie screamed like a slaughtered pig. The switchblade clattered to the concrete. He fell to his knees, clutching his shattered wrist.

Heidi closed the distance in three strides. She kicked his uninjured hand away and slammed the sharp heel of her stiletto down onto the back of his bleeding hand, pinning it to the concrete floor.

Bobbie shrieked in agony, thrashing on the floor.

Heidi pressed the hot muzzle of the Glock directly between his eyes. "Do you still want the Bitcoin?" she whispered.

Behind her, Caleb's sharp eyes darted around, landing on a jagged shard of rusted metal near the leg of his chair. He subtly shuffled his feet, using the sharp edge to saw relentlessly at the worn rope binding his ankles until it snapped. He quickly freed his sister, and pulled her behind a concrete pillar.

Bobbie sobbed, his face twisting in terror. "Please! I was just hired! I just wanted the money!"

Heidi ground her heel harder into his bone. "Who hired you? Give me a name!"

The pain broke Bobbie's mind. Desperate to find leverage, he screamed the one thing he thought would stop her.

"I'll tell you everything!" Bobbie gasped, spitting blood as his voice dropped to a desperate, raspy whisper that only she could hear. "It was Brigette! She saw how Christian looked at you today! She was terrified you'd take her place! But there's more! I know her biggest secret! She answers to a man she calls The General! They are the ones who arranged the warehouse fire four years ago! I set the blaze! I can testify against them!"

The words echoed off the metal walls.

Heidi froze. Her pupils dilated violently. Her finger tightened on the trigger.

The confession hung in the damp air, instantly chilling the blood in Heidi's veins. The warehouse fire. Four years ago.

Heidi didn't panic. Her eyes went completely dead. She pressed the barrel of the Glock harder into Bobbie's eyeball, forcing his head back against the concrete.

"Who is The General?" she asked, her voice dropping to a terrifying, icy whisper.

Bobbie trembled violently. "I don't know his real name! I swear! I just poured the gasoline that night! Brigette wanted the original wife dead so she could steal the Page heirs! Please, if you want to ruin Brigette, I'm your best weapon!"

Heidi's stomach twisted. The General. Brigette wasn't working alone four years ago. There was a deeper rot.

Before she could interrogate him further, the piercing wail of police sirens shattered the night. The heavy thud of helicopter rotors shook the tin roof of the factory.

Blinding white searchlights swept through the broken windows, illuminating the dust in the air.

Heidi cursed under her breath. Christian's men had tracked her.

She couldn't let Christian find Bobbie. If Christian interrogated him, Brigette and The General would realize their past crimes were exposed, and her ultimate targets would scatter into the shadows before she could destroy them piece by piece.

Heidi flipped the gun. She slammed the heavy steel grip directly into Bobbie's temple. His eyes rolled back, and he slumped unconscious to the floor.

She turned and ran to the pillar. She grabbed Caleb and Seraphina. "Close your eyes. Don't look at the blood."

She dragged them toward a rusted iron grate she had spotted on the blueprints. She kicked it open and pulled the children down into the dark maintenance tunnels just as the front doors exploded inward.

A SWAT team flooded the factory, laser sights cutting through the dark.

A moment later, Christian walked through the shattered doors. He wore his black overcoat, flanked by his elite security detail.

His dark eyes scanned the room. He saw the empty metal chairs. He saw the massive pool of fresh blood on the concrete.

His assistant knelt next to Bobbie. "Sir. Suspect is unconscious. Gunshot wound to the wrist. Blunt force trauma to the head."

Christian walked closer. His expensive leather shoe crunched on something metallic.

He looked down. He picked up a 9mm brass casing. He rubbed his thumb over the scratches on the metal. Suppressor marks.

The Surgeon wasn't just a doctor. She was a trained killer. The violent contradiction didn't push him away; it ignited a dark, obsessive fire in his chest.

"Mr. Page," a bodyguard called out from the corner. "Found this."

The guard handed Christian a tiny, black metal device. It was Caleb's SOS transmitter. Engraved on the back was a microscopic letter C.

Christian stared at the device. The metal was cold in his palm.

Suddenly, a memory slammed into his brain like a freight train. The blurry ultrasound photo from four years ago. The way the woman in the garage felt in his arms. The way the little girl at the airport had looked at him.

His heart started to hammer against his ribs. A wild, impossible theory clawed its way up his throat.

What if she didn't die? Whose children were those?

Christian turned his head, staring at the open grate leading into the tunnels. He could almost feel her ghost slipping away in the dark.

He dropped the brass casing and the transmitter into a plastic evidence bag. He handed it to his head of intelligence.

"Extract the DNA and fingerprints from this device," Christian ordered. His voice was a lethal, vibrating hum. "Run them through every database we have access to. I want to know who this child is. And run a facial recognition scan on the mother against all global records, cross-reference with any known associates of the Page family from four to five years ago. If anyone leaks this, I will bury them."

The wind howled through the broken factory windows, whipping Christian's coat around his legs. He stood in the blood-soaked room, his eyes burning with absolute certainty.

The game of hide and seek was over.

The black Range Rover glided into the underground private garage of the Manhattan penthouse like a ghost. The heavy engine cut out, leaving a suffocating silence in the dark cabin.

Heidi shoved her door open. Her legs were shaking, but she forced her muscles to lock. She ripped open the back door and pulled Seraphina into her chest. She buried her face in her daughter's hair, breathing in the scent of her skin. Her heart hammered against her ribs so hard it physically hurt.

Caleb jumped down from the other side. He adjusted his heavy tactical backpack. His cold eyes scanned the concrete pillars, confirming they had not been followed.

They walked into the private elevator. The heavy bulletproof steel doors slid shut, locking with a loud, mechanical thud.

The elevator shot up to the top floor.

Inside the penthouse, Heidi set the children on the plush sofa. She poured two glasses of warm milk. When she handed the glass to Seraphina, the collar of the girl's dress slipped down.

A dark purple bruise wrapped around her small neck. The rope burn.

Heidi's stomach violently cramped. The air vanished from her lungs. She stared at the bruised skin, and a wave of pure, blinding murder flooded her veins. Her fingertips turned ice-cold.

As she stood up, the heavy front door of the penthouse unlocked with a soft click. Alex Stone, her private security contractor who had been pre-positioned at the residence, stepped out of the foyer's shadows and walked into the living room. He dropped to one knee on the hardwood floor.

"I failed to detect the ambush, Dr. Surgeon," Alex said, his voice tight. "Punish me."

Heidi slowly stood up. She raised her hand, cutting off his apology. Her eyes were completely dead.

"Go to NewYork-Presbyterian Hospital," Heidi ordered, her voice devoid of any human emotion, slipping effortlessly into the cold, flawless British accent she had meticulously cultivated for her new identity. "Bobbie Weeks is there. Handle him."

Caleb suddenly unzipped his backpack. He pulled out a sleek black tablet and tapped the screen. A map with a blinking red dot appeared.

"Mommy," Caleb said, his brow furrowing as he looked up. "My tracker's signal just vanished. The map shows its last location was a big building with the Page company name on it... there were a lot of little test tube icons on the building's blueprint. The pin had my blood on it from when I pricked my finger."

Heidi's chest froze. Her mind raced through the implications at lightning speed. If Christian ran that DNA against the national database, he would find out Caleb was his biological son. Her entire four-year cover would be blown to pieces.

She didn't hesitate. She pulled her encrypted satellite phone from her pocket and dialed her brother's secure line.

"Iain," Heidi commanded, her voice a low, urgent hiss. "Christian has Caleb's DNA. He's running it at the Page Consortium bio-lab right now. I need your team to breach their network. Plant a Trojan, overwrite the results with a randomized negative string, whatever it takes. It has to be done before their sequencer finishes the run."

She watched the progress bar on her own mobile terminal as her brother's team synced with her. A moment later, it hit one hundred percent.

Heidi let out a sharp breath. The crushing weight on her chest lifted slightly. She looked at the confirmation screen, then turned her icy glare back to Alex.

"Go," she commanded.

Across the city, inside the ICU of NewYork-Presbyterian Hospital, Bobbie Weeks groaned. He was handcuffed to the metal bed rail. His shattered wrist throbbed with agonizing pain.

Outside the door, the two NYPD officers suddenly slumped to the floor without a sound.

The door pushed open. Alex Stone walked in. He wore a white doctor's coat and a blue surgical mask.

Bobbie's eyes widened. He opened his mouth to scream for help.

Alex lunged forward. He grabbed Bobbie's shattered wrist and twisted it violently.

Bobbie's jaw unhinged in a silent scream. The pain paralyzed his vocal cords. Sweat exploded across his forehead.

Alex pulled a glass syringe filled with clear liquid from his pocket. He pressed the sharp needle directly against Bobbie's throbbing carotid artery.

"If you breathe a single word about Heidi Mcdaniel to Christian Page," Alex whispered, his voice like grinding stones, "this neurotoxin will stop your heart in three seconds. You will suffocate while fully conscious."

Bobbie felt warm urine spread across the hospital sheets. He nodded frantically, his eyes bulging with absolute terror.

Alex sneered. He pulled a micro-listening capsule from his pocket. He forced Bobbie's jaw open and shoved the metal pill deep down his throat.

"Swallow," Alex ordered.

Bobbie gagged and swallowed. Alex turned and vanished into the hallway.

Ten minutes later, the door slammed open again.

Quinn Doyle, Christian's executive assistant, marched into the room with two massive bodyguards. His face was red with stress.

"Who hired you?" Quinn barked, grabbing Bobbie by the collar of his hospital gown. "Tell me everything about the woman in the factory!"

Bobbie shook violently. He looked at Quinn, but he felt the metal capsule sitting in his stomach.

"I don't know!" Bobbie cried out. "It was a random kidnapping! I just wanted the ransom! I swear to God!"

Quinn shoved him back onto the mattress in disgust. He pulled out his phone, his hands shaking. "Mr. Page. The suspect knows nothing. It's a dead end."

Inside the Manhattan penthouse, Heidi stood by the floor-to-ceiling window. She listened to Quinn's frustrated voice through the earpiece in her ear.

She pulled the earpiece out and crushed it under the heel of her stiletto.

Brigette dared to touch her children. The slow, methodical revenge plan was over. Heidi was going to burn her world to the ground right now.

She picked up her encrypted satellite phone. She dialed her brother, Iain Mcdaniel.

"Liquidate one billion dollars from the offshore trust," Heidi ordered. "Prepare to short the Page family's peripheral assets."

Her other phone lit up on the glass table. It was an email from Vanguard Academy. The admission applications for Caleb and Seraphina were approved.

Heidi gripped the edge of the table. Her knuckles turned white. The war for blood and power had officially begun.
