The little girl hit Dean Mercer’s study door so hard that it bounced off the stopper.

The storm passed by two in the morning, leaving Savannah wrapped in a thick, eerie river mist that clung to the Spanish moss and muffled every sound along the marsh.

Dean had moved Grace and Lily into the master wing on the third floor—the most heavily fortified section of the mansion, featuring reinforced steel doors, independent power generators, and private surveillance monitors. Owen’s crib was placed directly beside Dean’s own bed.

For the first time in five months, Dean had fallen into an actual sleep.

It lasted exactly three hours.

At four-fifteen a.m., a faint, metallic vibration hummed through the bedside console.

Dean was awake before his eyes even opened. His hand cleared the drawer, fingers wrapping around the grip of his SIG Sauer.

The master bedroom door was locked. Owen was sleeping soundly, his breathing soft and steady. In the adjoining room, through the open double doors, Grace and Lily were fast asleep on the king-sized guest bed, Lily sprawled out like a starfish across the duvet.

Dean tapped the console screen.

The perimeter alert showed a breach at the old boathouse on the river edge.

*Camera 14: OFFLINE.*

*Camera 15: OFFLINE.*

Dean frowned. Marcus was running the night patrol with six elite operatives. If there was a glitch, Marcus would have radioed immediately.

Dean pressed the intercom button. "Marcus. Report."

Static.

Dean pressed it again. "Marcus. Status check."

A voice came over the speaker, but it wasn't Marcus.

It was a voice that sounded like gravel grinding against rusted iron.

"Marcus is currently taking a nap on the dock, Dean. You always did rely too much on military boys. They think in straight lines. They don't think like river rats."

Dean’s blood turned to ice water.

*Sal Moretti.*

The head of the Moretti crime family out of Charleston—Dean’s fiercest rival for control of the Southeastern container ports. Six months ago, Dean had seized two hundred million dollars worth of illicit pharmaceutical shipments off Moretti’s freighters, effectively cutting the Charleston family’s revenue in half.

"Sal," Dean said, his voice dropping into a razor-sharp whisper.

"Martha was a very expensive investment, Dean," Moretti rasped through the speaker. "Cost me nearly three million over two years to turn that old woman. She was supposed to deliver the baby to my boys at the south gate yesterday afternoon. We were going to trade Owen for the shipping manifests and your total withdrawal from the Savannah harbor."

Dean’s grip on his gun tightened until his knuckles went dead white.

"She botched it," Moretti continued casually. "Got sloppy. Let some maid's brat ruin an eighteen-month operation. So, I had to come down here myself to clean up the mess."

"You're inside the gates," Dean said.

"I’m in the foyer, Dean. With ten men. We have the lower floors locked down. You have your bedroom door, your gun, and about three minutes before we blow the hinges with thermite. Bring the baby down. Sign the port transfer deeds on your desk. And maybe... just maybe... I let you and your new housemaid walk out into the marsh alive."

The intercom clicked dead.

Dean didn't panic. He moved with the deadly, calculated efficiency of an apex predator backed into a corner.

He crossed into the adjoining bedroom.

Grace was already sitting up, alerted by the low rumble of his voice over the intercom. Her eyes were wide in the moonlight.

"Dean? What is it?"

"Get up, Grace," Dean said quietly, kneeling beside the bed. "Put Lily's shoes on."

"Who was that on the speaker?"

"Sal Moretti. He has men on the ground floor."

Grace’s breath caught in her throat, but she didn't scream. She didn't freeze. She immediately reached over, gently shaking Lily awake. "Lily, sweetie. Wake up. We have to play an undercover game."

Lily rubbed her eyes, blinking sleepily. "Is it doctor time?"

"Yes, baby. Emergency doctor time."

Dean walked to the massive oak wardrobe in the corner of the room. He reached inside, pushed aside three suits, and pressed his thumb against a concealed biometric scanner hidden in the cedar backing.

With a soft hydraulic hiss, the entire back panel swung open, revealing a narrow, vertical staircase lined with emergency lighting.

"This is Natalie’s panic route," Dean said, pulling Grace and Lily toward it. "It leads directly to a reinforced underground storm shelter beneath the carriage house, three hundred yards from the main mansion. The door at the bottom is three-inch ballistic steel. It can only be opened from the inside, or by my biometric code."

He scooped Owen from his crib, wrapped him in a heavy wool blanket, and placed him directly into Grace’s arms.

"Take Owen," Dean said. "Go down the stairs. When you reach the vault door, close it. Turn the manual wheel clockwise until the red pins engage. Do not open that door for anyone except me."

Grace looked at him, her eyes searching his face. "You're not coming with us."

"I have to draw them away from the carriage house," Dean said, checking the magazine of his sidearm and racking the slide. "If they see the bedroom is empty, they’ll search the perimeter. I need them focused on me."

"Dean, there are ten of them!" Grace grabbed his arm, her fingers sinking into his sweater. "You can't fight ten men alone!"

"This is my house, Grace," Dean said, and for a fleeting second, a dark, terrifying smile touched his lips. "They think they broke into a fortress. They don't realize they walked into an abattoir."

He looked down at Lily, who was holding her little doctor’s kit tightly against her chest.

"Doctor Lily," Dean said.

Lily looked up. "Yes?"

"Keep Owen safe. That’s your chief medical assignment. Can you do that?"

Lily puffed out her chest, nodding with immense gravity. "Chief Doctor Lily is on duty."

"Good girl." Dean looked at Grace, his hand reaching up to touch the side of her neck, his thumb brushing her cheekbone. "Go. Now."

Grace hesitated for half a second, then leaned up and pressed a fierce, desperate kiss against his cheek. "Come back to us, Dean Mercer. Don't you dare die tonight."

"Never again," Dean whispered.

He closed the heavy panel behind them, listened for the click of the internal lock, and then turned toward the heavy mahogany doors of the master bedroom.
