Ashlee walked into the main briefing room. The air conditioning blasted cold air from the vents.

She pulled off her wet tactical gloves. She threw them onto the center of the holographic projection table. The heavy, wet fabric hit the glass surface with a loud smack.

Zane Carrick stood on the other side of the table. He was the chief intelligence officer. He wore a gray sweater. He looked exhausted.

He tapped a few keys on his console. The holographic table lit up.

Grainy security footage appeared in the air. It was full of static and snow.

"This is all we recovered from the vault cameras," Zane said. He pointed at the screen. "The intruder used a highly specific frequency jammer. It completely fried our local feeds."

Ashlee stared at the static. "Who uses that frequency?"

"The Defense Intelligence Agency," Zane said. "It's a proprietary DIA counter-surveillance band. It's not available on the black market."

Ashlee's eyes narrowed. She looked at the still image of the shadow falling off the cliff. A cold, predatory focus settled in her stomach.

Zane typed another command. The screen changed. A digital folder appeared. A red warning label flashed across the front: RESTRICTED ACCESS.

"File 531," Zane said. He rubbed the back of his neck. "You know what this means, Ashlee. The 531 explosion involves high-level government officials across three countries. If this leaks, the fallout will be catastrophic."

Ashlee let out a short, harsh laugh. "I know exactly what the fallout looks like, Zane. I was there."

She turned away from the table. She walked over to the floor-to-ceiling windows. The storm outside was finally slowing down. The rain tapped lightly against the glass.

Her chest tightened. The physical pressure squeezed her lungs.

She remembered the rain in Boston four years ago. She remembered the cold hands grabbing her arms. She remembered being shoved into the back of a black SUV. That night had ripped her life apart. It had turned her into the weapon standing in this room.

She pushed the memory down. She turned back to Zane.

"Initiate a global kill order," Ashlee said. Her voice carried no emotion. "Level one."

Zane shook his head. He pulled up a satellite map of the Atlantic coast.

"I tracked the thermal signature in the water after you shot him," Zane said. "A submarine picked him up. No transponder. Stealth coating. It vanished off the grid ten minutes later."

"Where was it heading?" Ashlee asked.

Zane traced a line on the map. "The trajectory points straight to the East Coast of the United States. Specifically, the waters off Massachusetts."

Ashlee walked back to the table. She placed her index finger hard on the map. She pressed down on the city of Boston.

"I am going to Boston," Ashlee said. "I will retrieve the file. I will kill the ghost who took it."

Zane frowned. "You can't just walk into the US. If you enter as Black Mamba, Homeland Security will flag you before your plane lands. The DIA will be waiting for you."

Ashlee's lips curved into a cold smile. "I don't need to enter as Black Mamba. I have a perfectly legal civilian identity."

"You haven't used that name in four years," Zane said.

"Pull up the Maddox family file," Ashlee ordered.

Zane sighed. He typed on his keyboard. A picture of Finley Maddox appeared on the screen. He wore a tailored suit and a fake smile. He was a prominent Boston billionaire.

"It's time I paid my biological parents a visit," Ashlee said. Her voice was like crushed ice.

"They've been trying to contact you for weeks," Zane noted.

"I know," Ashlee said.

"I'll prepare your cover," Zane said. He started typing rapidly. "I'll create a flawless high school transcript. Ivy League standard. It will explain your absence and justify your return."

Ashlee nodded. She walked out of the briefing room.

She went to her private quarters. She stripped off the wet tactical vest and the heavy boots. The smell of rain and sweat washed down the drain in a three-minute cold shower.

She walked into her closet. She bypassed the tactical gear.

She pulled out a black silk shirt. It was expensive. It felt soft and fragile against her skin. She put on a pair of dark designer jeans.

She sat on the edge of her bed. She picked up a pair of black Chelsea boots. She reached into her drawer and pulled out a custom-made ceramic folding knife. The blade was matte black. It would not trigger airport metal detectors.

She slid the knife into a hidden compartment in the heel of the right boot. She put the boots on.

She grabbed a black Hermes Birkin bag from the top shelf. It looked like a standard luxury item. Inside, the lining was woven with military-grade anti-surveillance mesh. It held a frequency scanner, an encrypted phone, and three fake passports.

She walked out to the secret runway behind the base.

A Gulfstream G650 waited on the tarmac. It had no tail number. The engines whined loudly in the damp air.

Ashlee climbed the stairs. She stepped into the luxurious cabin. The smell of rich leather filled the space.

She sat down in the wide leather seat. She reached for the crystal decanter on the side table. She poured two fingers of bourbon into a glass. She drank it straight. The alcohol burned a hot path down her throat.

The plane accelerated and lifted off the ground. The force pushed her back into the seat.

She pulled a tablet from her bag. She opened the recent financial reports for the Maddox Corporation.

She scrolled through the data. Red numbers filled the screen. The company's stock was plummeting. They were bleeding cash.

Ashlee stared at the numbers. Her jaw tightened.

She understood instantly. Her parents didn't want her back because they missed her. They wanted her back because she was turning eighteen. They wanted the massive trust fund her grandfather had left exclusively in her name.

She tossed the tablet onto the empty seat next to her.

She closed her eyes. She forced her breathing into a slow, rhythmic pattern. She needed tactical sleep.

Three hours later, the plane touched down smoothly at Logan International Airport in Boston.

Ashlee opened her eyes. She reached into her bag and pulled out a pair of dark Tom Ford sunglasses. She slid them onto her face. They hid the cold, dead look in her eyes.

She stood up, grabbed her bag, and walked down the stairs.

The Boston air was crisp. She stepped onto the tarmac. She was ready to face the liars who called themselves her family.

The automatic doors of the VIP arrivals terminal slid open. A blast of cold Boston wind hit Ashlee's face.

She pushed a standard luggage cart. On it sat a heavy, black tactical duffel bag.

She looked through her dark sunglasses. She scanned the crowd waiting behind the velvet ropes. Her eyes locked onto two figures standing slightly apart from the rest.

Finley Maddox wore a charcoal gray Brioni suit. He checked his Patek Philippe watch. Next to him stood Averi Maddox.

Averi wore a pristine white Chanel tweed suit. Her blonde hair was perfectly styled. She looked like the ultimate innocent socialite.

Averi spotted Ashlee. Her face instantly transformed. A wide, bright smile stretched across her lips. She took quick, eager steps forward.

"Ashlee!" Averi cried out. Her voice was high-pitched and sweet.

Averi threw her arms open. She lunged forward to pull Ashlee into a tight, sisterly embrace.

Ashlee didn't blink. Her body reacted on pure instinct.

She shifted her weight to her right foot. She slid half a step to the left. The movement was smooth and completely effortless.

Averi's arms closed around empty air.

Her momentum carried her forward. Her high heel twisted on the polished floor. Averi let out a sharp gasp. She stumbled awkwardly, her arms flailing before she caught her balance. Her face flushed bright red.

From the corner of her eye, Ashlee saw a flash of light.

She turned her head slightly. Sixty feet away, half-hidden behind a concrete pillar, two men held long-lens cameras. They were snapping photos rapidly.

Finley saw Averi stumble. His brow furrowed in deep annoyance. He took long strides forward and grabbed Averi's arm to steady her.

He looked at Ashlee. His eyes were cold and critical.

"Is this how you behave after four years?" Finley hissed. He kept his voice low so the surrounding people couldn't hear. "You humiliate your sister in front of the press? Have you learned absolutely no manners?"

Ashlee reached up and pulled off her sunglasses.

She stared directly into Finley's eyes. Her gaze was completely dead. It was the look of a butcher staring at a piece of meat.

Finley's mouth opened slightly. He felt a sudden chill run down his spine.

"The guy on the left is using a Canon EOS-1D X," Ashlee said. Her voice was flat and bored. "The guy on the right has a Sony Alpha 1. You paid them to be here. You want a picture of the happy family reunion to boost your stock price."

Finley's face went rigid. His breath hitched in his throat.

He stared at her in shock. How could she possibly know the exact camera models from sixty feet away?

Averi's eyes filled with tears. She grabbed Finley's sleeve. Her lower lip trembled perfectly.

"Dad, don't be mad at her," Averi said softly. "She's been living in those horrible places in Eastern Europe. She just doesn't understand how things work in Boston."

Ashlee turned her head. She looked at Averi.

Ashlee took one step forward. She closed the distance between them. She stopped exactly ten centimeters from Averi's face.

Averi's breath caught. She looked up into Ashlee's eyes.

Ashlee leaned in. The scent of cold rain and mint washed over Averi.

"Say one more word," Ashlee whispered. Her voice was barely audible, but it carried the weight of a loaded gun. "And I will rip your tongue out of your mouth."

Averi's face drained of all color. Her stomach dropped. A wave of pure, physical terror crashed over her. Her hands started to shake. She took a frantic step backward, bumping into Finley.

A man in a black chauffeur uniform hurried over. He looked nervous.

"Miss Maddox, let me take your bag," the driver said.

He reached for the black tactical duffel on the cart. He grabbed the handles and pulled upward.

The bag didn't move.

The driver grunted. He planted his feet and pulled harder. His face turned red. The veins in his neck bulged. The bag barely lifted an inch before dropping back onto the cart with a heavy thud.

Ashlee sighed. She pushed the driver aside.

She grabbed the handles with one hand. The muscles in her arm tensed, and she lifted the heavy bag off the cart in one steady, controlled motion. There was no wasted energy, no trembling.

She walked to the waiting stretch Lincoln. She tossed the bag into the open trunk.

The heavy bag hit the floor of the trunk. A loud, metallic slam echoed in the parking garage. The entire rear end of the heavy Lincoln bounced on its suspension.

Finley's eye twitched. He stared at the trunk.

Ashlee didn't wait for the driver to open the door. She pulled the rear door open herself. She slid into the spacious cabin. She sat directly in the right-side passenger seat. It was the seat of power. It was Finley's seat.

Finley clenched his fists. He needed her signature on the trust fund documents. He forced himself to swallow his anger.

He guided the shaking Averi into the car. They sat on the rear-facing seats, directly opposite Ashlee.

The driver closed the door. The heavy thud sealed them inside.

The air in the car was suffocating. The smell of expensive leather and Averi's sweet perfume made Ashlee's stomach turn.

The car pulled out of the airport.

Finley forced a tight smile. "So, Ashlee. How were your years in Eastern Europe? Did you learn anything useful?"

Ashlee leaned her head back against the headrest. She closed her eyes. She ignored him completely.

Finley's face hardened. He looked out the window.

Averi sat quietly. She pulled out her phone. Her thumbs flew across the screen. She was texting her friends, complaining about the savage her parents had brought home.

The Lincoln drove through the wealthy suburbs of Boston. Hundred-year-old oak trees cast dark shadows over the road.

The car slowed down. It turned into a long driveway and stopped in front of massive wrought-iron gates. Beyond the gates stood a sprawling Victorian mansion.

Ashlee opened her eyes. The hunt was about to begin.

The heavy oak front doors of the Maddox estate swung open.

Ashlee stepped into the grand foyer. Her boots sank into the thick Persian rug. The air smelled of lemon polish and old money.

Johanna Maddox stood at the top of the sweeping staircase. She wore a silk robe. She held a crystal glass of sparkling water. She looked down at Ashlee.

Johanna's upper lip curled in disgust. She didn't try to hide it.

"Take her to the guest room at the end of the east wing," Johanna told the butler. Her voice was sharp and dismissive. "The one furthest from our rooms."

Ashlee didn't look up. She didn't acknowledge Johanna's presence. She grabbed her heavy duffel bag and walked straight up the stairs.

She passed Johanna on the landing.

A cold draft seemed to follow Ashlee. Johanna felt the sudden drop in temperature. She shivered and pulled her silk robe tighter around her shoulders.

Ashlee walked down the long, silent hallway. She found the room at the very end.

She pushed the door open. She stepped inside and kicked the door shut behind her. She turned the deadbolt. She flipped the latch. She hung the "Do Not Disturb" sign on the outside handle before closing it.

She dropped her bag onto the hardwood floor.

She unzipped the top pocket. She pulled out a small device. It looked like a tube of black lipstick.

She pressed a button on the bottom. A tiny green light blinked to life. It was a military-grade frequency scanner.

Ashlee walked slowly around the room. She swept the device over the bedside lamps. She moved it along the baseboards.

Near the large oil painting of a horse, the scanner emitted a low, rapid buzzing sound.

Ashlee smiled coldly.

She reached behind the heavy gold frame. Her fingers felt the smooth surface of the wall. She found a small bump. She dug her fingernail under it and pulled.

She held a micro-transmitter in her palm. It was a cheap, civilian-grade bug.

She walked to the nightstand and found a second one taped under the drawer.

She didn't crush them. She carried both bugs into the massive marble bathroom. She dropped them into the dry bathtub.

She reached over and turned the brass faucet. Water gushed out, hitting the marble with a loud, continuous roar. The white noise would drown out any conversation in the room.

Ashlee walked back into the bedroom. She reached into her bag and pulled out her encrypted phone.

She typed in a thirty-digit dynamic passcode. The screen unlocked. She pressed the single contact listed.

The call connected instantly.

"Mamba," Zane's voice came through the speaker. Zane's voice was distorted by the encryption, and the background was completely silent.

"Report," Ashlee said.

"I'm at an underground surgical clinic in South Boston," Zane said. "I paid the doctor ten grand to talk. An hour ago, a man came in. He bought a massive amount of local anesthetics, surgical glue, and hemostats. He paid in cash and left."

"Did the doctor get a look at him?"

"No. The guy wore a hood and a mask," Zane said. "But the doctor noticed the smell. He said the guy smelled strongly of sea salt and burnt cordite."

Ashlee's eyes sharpened. Her pulse ticked slightly faster against her throat.

The ocean. The gunshot. It was him.

"I'm sending you a photo," Zane said. "I dug it out of the clinic's biohazard bin."

Ashlee's phone buzzed. She opened the encrypted image.

It was a picture of a bloody piece of gauze. Sitting in the center of the dark red stain was a small, mangled piece of metal.

Ashlee zoomed in on the metal.

The edges of the fragment were peeled back in a very specific, jagged pattern. It looked like a blooming metal flower.

Ashlee's jaw tightened. Her thumb traced the image on the screen.

It was the signature expansion pattern of the custom hollow-point rounds she used in her Barrett. The bullet had hit him, shattered against his body armor or bone, and he had dug this piece out himself.

"He's in Boston," Ashlee said. A dark thrill rushed through her veins.

"Mamba, listen to me," Zane said. His voice was tense. "If he took a hit from that round and still managed to escape, cross the ocean, and walk into a clinic... he is not a normal target. He is extremely dangerous."

Ashlee walked to the window. She pulled back the heavy velvet curtains. She looked out at the glittering skyline of Boston.

"The harder they fight, the better the hunt," Ashlee whispered.

"I'm sending the gauze to a black-market lab to extract DNA," Zane said. "It will take a few hours."

"Do it," Ashlee said. She hung up the phone.

She walked back to her duffel bag. She reached deep into the side compartment. Her fingers wrapped around the cold polymer grip of her Glock 19.

She pulled the gun out. She pressed the magazine release. The empty mag slid into her palm. She pulled the slide back, checking the chamber.

Click. Clack.

The sharp, metallic sounds echoed in the quiet room.

Downstairs, a piano started playing. It was a classical piece, played with exaggerated emotion. Averi was showing off for her parents.

Ashlee picked up a box of 9mm ammunition. She pressed the brass cartridges into the magazine, one by one.

She stared at the floorboards. She imagined the pathetic family sitting in the living room below. They had no idea a monster was sleeping in their guest room.
