The Kaufman estate in the Hamptons wasn't a home; it was a fortress of grey stone and cold ambition. High walls, cameras every ten feet, and a gate that looked like it could stop a tank.

The convoy swept through the entrance. Rain lashed against the windows.

As the SUV stopped, the front doors of the manor burst open. The head butler, a man who usually looked like he was carved from granite, ran out into the rain.

"Dr. Sterling!" he shouted. "It's Alistair! He's crashing! Hematemesis!"

Sterling's face went white. She grabbed her bag and sprinted toward the house, leaving Barron and the security team behind.

Two bodyguards hauled Barron into a wheelchair. He slumped over, drool glistening at the corner of his mouth, playing the part perfectly. But under his lashes, his eyes were sharp, scanning the perimeter.

Kaela stepped out of the car. No one looked at her. She was the luggage.

She stood in the rain, listening. Hematemesis. Vomiting blood.

She remembered the file Onyx had sent her. Alistair Kaufman. Suspected poisoning. The only thing holding the family trust together.

If the old man died tonight, Barron-the "invalid"-would be declared incompetent by the board tomorrow. The assets would be stripped. Her marriage contract would be worthless.

No deal.

Kaela tightened her grip on her bag and followed the commotion inside.

She slipped through the grand foyer, unnoticed in the chaos, trailing the medical team up the marble staircase.

The master bedroom smelled of death. Copper and rot. Kaela noted the room was designed as a Faraday cage; no signals in or out. No cameras. A true dead zone.

Alistair Kaufman, the lion of Wall Street, lay on a massive four-poster bed. His skin was the color of old parchment. Dark blood stained the silk sheets.

Sterling was frantic. "BP is dropping! 60 over 40! Get the crash cart! Prep for intubation!"

Kaela stood in the doorway. She saw the black veins tracking up the old man's neck.

"Intubation will kill him," she said. Her voice cut through the panic like a scalpel. "His lungs are full of necrotic fluid. The pressure will burst the alveoli."

The room went silent. Sterling spun around.

"Who let her in?" she screamed. "Get out! Security!"

Two guards moved toward Kaela.

Kaela didn't back down. She looked past them, straight at Barron, who had been wheeled into the corner of the room.

She locked eyes with him. Do you want him dead?

Barron's face remained slack, but his right index finger tapped the armrest of his wheelchair. Twice.

The head of security, a man named Graves who had served Barron for ten years, saw the signal. He stepped in front of the other guards.

"Wait," Graves said. "Let her speak."

"Are you insane?" Sterling shrieked. "She's a hillbilly! She's high on meth for all we know!"

Kaela walked to the bed. She pulled back Alistair's eyelids. "Pinpoint pupils. Black gum line. This isn't heart failure. It's 'Black Mamba' neurotoxin cocktail."

She reached into her boot and pulled out a folding knife. The blade was silver, dull-looking, but razor sharp.

"She's got a weapon!" Sterling yelled. "Call the police!"

Kaela ignored her. She grabbed Alistair's foot. "I need to drain the pressure from the meridian points before the heart stops."

Sterling lunged at her.

CRASH.

A Ming vase shattered against the wall.

Everyone jumped.

Barron was thrashing in his chair, making guttural, animalistic noises. He swung his arms wildy, knocking over a table.

"Out!" he roared, the word slurred but intelligible. "Get... OUT!"

Graves moved instantly. "Mr. Kaufman is having an episode! Clear the room! Everyone out!"

He grabbed Sterling by the arm. "But the patient-"

"Out!" Graves shoved the doctor and the nurses into the hall. He looked at Kaela, then at Barron, and closed the heavy oak doors, sealing them inside.

The room fell silent, save for the beep of the monitor.

Kaela looked at Barron. He stopped thrashing. He sat up straight, wiped his mouth, and looked at her with terrifying intensity.

"Save him," Barron said. His voice was deep, clear, and commanded absolute obedience.

Kaela didn't blink. "Pass me a towel."

Barron grabbed a clean towel from the cart and threw it to her.

Kaela caught it one-handed. She didn't waste time asking questions about his miraculous recovery. They were co-conspirators now.

She knelt at the foot of the bed. She used the silver knife to make a small, precise incision on the sole of Alistair's foot, right at the kidney point.

A dark, viscous blood oozed out. It wasn't black, but a deep, unhealthy crimson that carried a faint, acrid chemical smell.

"Hold his leg," Kaela ordered.

Barron left the wheelchair. He walked-steady, powerful strides-to the bed and clamped his hands around his grandfather's calf.

Kaela reached into her canvas bag and pulled out a small glass jar. Inside, two translucent, gelatinous creatures swam in water.

Leeches.

Barron raised an eyebrow. "This is your plan? Medieval witchcraft?"

"It works," Kaela said, using tweezers to place a leech on the incision. "Unlike your Dr. Sterling, who treats the symptoms, these eat the poison."

The leech latched on. Its body began to swell, though its color remained largely unchanged.

"Why the act?" Kaela asked, her eyes focused on the wound. "You could run this empire in your sleep."

"To see the rats," Barron said, watching the color slowly return to his grandfather's face. "Someone in this house is dosing him. And me."

"Sterling?"

"She's a pawn. I need the king."

The monitor beeped faster. Stronger. Alistair took a deep, rattling breath. The dark lines on his neck began to fade.

"Toxin load is down 80%," Kaela said. She plucked the gorged leech off and dropped it back into the jar. "He needs herbal chelation to get the rest."

BANG. BANG. BANG.

"Open up! Police!"

Sterling's voice came through the wood. "She's murdering him! Break it down!"

Kaela wiped her hands on the towel. She looked at Barron. "Showtime."

Barron nodded. In a split second, the powerful CEO vanished. He slumped back into the wheelchair, head lolling to the side, eyes rolling back.

Kaela unlocked the door.

Three police officers burst in, guns drawn, with Sterling right behind them.

"Hands in the air!"

Sterling pointed at the blood on the floor. "See! She cut him! She killed him!"

An officer grabbed Kaela, spinning her around. He slapped cuffs on one wrist.

"You're under arrest for..."

"Sterling..."

The voice was weak, raspy, but undeniable.

The officer froze. Sterling froze.

On the bed, Alistair Kaufman opened his eyes. He blinked, focusing on the ceiling, then turned his head slowly.

"Shut... up," Alistair croaked.

Sterling gasped. "Mr. Kaufman? But... the monitor said..."

She looked at the screen. Vitals were stable. Better than they had been in months.

"Impossible," she whispered.

Kaela twisted her wrist, slipping out of the officer's grip before he could lock the second cuff.

"Attempted murder?" Kaela asked, rubbing her wrist. "Looks like a life-saving procedure to me."

Alistair looked at Kaela. His eyes were old, tired, but sharp. He saw the blood on her hands, the jar in her bag.

"You..." he wheezed. "Who are you?"

"The new asset," Kaela said coolly. "And don't forget to pay the bill."

From the wheelchair, hidden by the bulk of his body, Barron's hand hung limp. But his thumb gave a small, subtle twitch. A thumbs up.

An hour later, the house was quiet. Alistair was sleeping-real sleep this time.

Graves knocked on the door of the guest room where Kaela was washing the blood off her hands.

"The younger Mr. Kaufman wants to see you," Graves said. "In the study. It's secure."

Kaela followed him down a hidden corridor to a room lined with books. There were no windows.

Barron was standing by the fireplace, pouring a glass of amber liquid. He wore a fresh suit, tailored to perfection. He looked nothing like the invalid in the wheelchair.

He didn't turn around when she entered. He just held out a folder.

"Sign it."

Kaela took the folder. It was a Prenuptial Agreement. But the terms...

Clause 4: Upon completion of one year of marriage, the Spouse shall receive title to the penthouse suite at 440 Park Avenue.

A palace in the sky.

"Hush money?" Kaela asked, tossing the folder onto the desk.

Barron turned. He took a sip of his drink, his eyes tracking her every move. "A dowry. I need a shield. You need a weapon. The Moon family threw you away. I'm offering you the means to bury them."

Kaela walked up to him. She stepped into his personal space. She inhaled. The sandalwood was stronger now, mixed with the whiskey.

"You need me because I'm your Ambien," she said softly. "I'm the only thing that quiets the noise."

Barron's jaw tightened. She was sharp.

"Mutual benefit," he said, his voice dropping an octave. "You get the money. I get the sleep. And we both get revenge."

Kaela picked up a pen. "Deal. But I have a condition."

"Name it."

"Tonight. The Moon Family Gala. I want you to go with me."

Barron frowned. "I'm supposed to be a vegetable."

"Exactly," Kaela smiled. It was a cruel, beautiful smile. "I want you to roll in there and make them look at us. I want my father to see that even a 'cripple' can destroy him."

Barron looked at the fire in her eyes. He felt a stir of something he hadn't felt in years. Excitement.

"As you wish," he said.

Kaela's phone buzzed. She pulled it out.

It was a live stream link. Jenna Moon, standing on a stage in a red dress, fake tears streaming down her face.

"My sister... she's missing. We fear she's back on drugs... it's heartbreaking..."

Kaela laughed. "She's good."

Barron glanced at the screen. "That's the sister?"

"The one who ordered the hit."

Barron pressed a button on his desk intercom.

"Graves. Prep the helicopter. And get the S-76. The black one."

"Helicopter?" Kaela asked.

Barron buttoned his jacket. His face went slack, his body language shifting back into the broken man. But his eyes remained lethal.

"If we're going to crash a party," he mumbled, "we should make an entrance."

They walked out of the study. Barron slumped in the chair, Kaela pushing him.

They passed Dr. Sterling in the hall. Sterling glared at them.

Kaela smiled sweetly. "We're going to a party, Doctor. Don't wait up."
