Housemaid Sarah Miller was pouring wine at the banquet table when her eight-year-old son appeared beside her, clutching his blue lunchbox.

The narrow service hallway was bathed in the harsh, fluorescent light of the kitchen.

I froze, the heavy assault rifle slipping slightly in my sweaty hands. My heart hammered against my ribs like a trapped bird.

Rosalind stood at the far end of the corridor, her red silk gown torn at the hem, her makeup ruined, but the gun in her hand was perfectly steady. The suppressor made the weapon look unnaturally long and lethal.

The black barrel was pointed squarely at my eight-year-old son’s chest.

“Mommy,” Toby whimpered, burying his face into my apron, trembling violently.

“I said, drop the guns,” Rosalind repeated, her voice echoing coldly against the tile walls. “Or I paint this hallway with his blood.”

Vincent didn't hesitate. He slowly bent his knees, placing his assault rifle carefully onto the linoleum floor. He kicked it away.

“Drop it, Sarah,” Vincent ordered quietly, not taking his eyes off Rosalind.

I swallowed the bile rising in my throat and let the heavy weapon clatter to the floor. I held my hands up, stepping slightly in front of Toby to shield him with my body.

“Good,” Rosalind sneered, taking a slow step forward. “Now kick them over to me.”

Vincent kicked both rifles down the hall. They skidded to a halt at Rosalind’s feet.

The pounding on the kitchen doors behind us grew louder, the wood beginning to splinter. We were trapped between Rosalind and a heavily armed death squad.

“You think you’ve won, Rosa?” Vincent asked, using her real name, his voice a low, vibrating growl of suppressed violence. “You think your father can hold this city? My men will burn the Falcone syndicate to the ground for this.”

Rosalind laughed, a brittle, manic sound.

“Your men are currently being slaughtered in the west wing, Vincent,” Rosalind smiled. “My father’s strike team breached the perimeter five minutes ago. By the time the sun rises, the Hale syndicate will be a footnote in Chicago’s history.”

She raised the pistol slightly, shifting her aim from Toby to Vincent’s chest.

“And it all starts with cutting off the head of the snake.”

“If you kill him, you have nothing to bargain with!” I shouted desperately, trying to buy us seconds. “The police will respond to the gunfire! You’ll never make it out of the estate!”

Rosalind’s eyes flicked to me, filled with absolute disdain.

“You really are a stupid maid,” Rosalind mocked. “The police in this district belong to my father. They won't respond for at least an hour. We have plenty of time to clean up this mess.”

She turned her attention back to Vincent.

“Before you die, Vincent, I want something from you,” Rosalind demanded, her tone hardening.

“I have nothing to give you,” Vincent said coldly.

“You have the watch,” Rosalind snapped. “The silver pocket watch the brat brought to dinner.”

Vincent frowned, feigning ignorance. “It’s a broken family heirloom. It means nothing to you.”

“Don't play dumb with me!” Rosalind shrieked, her composure cracking. “I know what’s inside it! I know Thomas didn't just hide a train ticket!”

My breath caught.

Vincent remained perfectly still, but his eyes narrowed imperceptibly.

“What else is in the watch, Rosa?” Vincent asked softly.

“The offshore routing numbers!” Rosalind yelled, desperation leaking into her voice. “Thomas was the only one besides you who knew the access codes to the Hale syndicate’s untraceable accounts. When I confronted him in the alley three years ago, he laughed in my face. He told me he had engraved the routing numbers into the casing of that watch, and that my father would never see a dime of it!”

I stared at the back of Vincent’s head, my mind racing. Thomas had engraved the bank codes into the watch? The watch Toby had been playing with for three years?

“I searched his body for an hour after I had him shot,” Rosalind wept furiously. “I tore his apartment apart. I couldn't find it. I thought he was bluffing. Until tonight. When that little rat pulled it out of his lunchbox.”

She pointed the gun at me.

“Give me the watch, Sarah. Hand it over, and I’ll let you and the boy walk out the back door. I swear it.”

I looked at Vincent. I looked at Rosalind.

I reached into the deep pocket of my maid’s apron. My fingers closed around the cold, heavy silver of the shattered pocket watch. I had snatched it off the table when the shooting started.

“Don't do it, Sarah,” Vincent warned quietly, not looking back at me. “If you give it to her, she’ll shoot you the second it’s in her hand. She can’t leave witnesses.”

“He’s lying!” Rosalind panicked. “Give it to me, Sarah! I’ll let you live!”

I slowly pulled the silver watch from my pocket. It gleamed dully under the fluorescent lights.

“You want it?” I asked, my voice trembling, forcing myself to look terrified.

“Toss it to me,” Rosalind ordered, holding out her free hand, her eyes locked greedily on the silver heirloom.

I raised my arm, pretending to prepare a throw.

But I didn't look at Rosalind. I looked at the ceiling directly above her head.

As the head housekeeper, I knew every inch of this mansion. I knew every flaw, every repair, and every hidden system.

Directly above Rosalind’s head was the primary junction box for the industrial fire suppression system. It was designed to flood the kitchen with high-pressure, chemical foam in the event of a catastrophic grease fire.

I didn't throw the watch at Rosalind.

I threw it with all my strength directly at the red glass emergency trigger embedded in the wall next to her.

The heavy silver watch smashed into the glass.

CRASH.

The alarm shrieking was instantaneous and deafening.

Before Rosalind could even register what had happened, the ceiling nozzles above her exploded open.

A massive, violent torrent of thick, white, blinding chemical foam blasted downward with the force of a firehose, hitting Rosalind directly in the face and chest.

She screamed, blinded and suffocating in the thick foam. The suppressed pistol discharged wildly, the bullet ricocheting harmlessly off the tile floor.

“Now!” I screamed, grabbing Toby’s hand.

Vincent didn't need to be told twice. He sprinted forward, diving through the wall of white foam, and tackled the blinded, choking Rosalind to the ground. He wrenched the pistol from her grasp and delivered a brutal, precise strike to her temple.

Rosalind went limp, instantly unconscious in the growing puddle of chemicals.

Vincent stood up, wiping the stinging foam from his eyes, holding Rosalind’s suppressed pistol.

CRACK.

The heavy kitchen doors behind us finally gave way, splintering violently off their hinges. Four Falcone mercenaries poured into the kitchen, shouting orders.

“Run!” Vincent roared, grabbing my arm and practically dragging me down the service corridor.

We sprinted through the maze of back hallways, the sounds of shouting and gunfire echoing behind us. We reached the heavy, reinforced steel door of the master library.

Vincent punched a frantic code into the keypad. The light flashed green, and the heavy door hissed open.

We threw ourselves inside, and Vincent slammed the door shut, throwing the massive internal deadbolts.

The library was entirely soundproofed. The sudden, absolute silence in the room was jarring. Floor-to-ceiling bookshelves lined the mahogany-paneled walls, smelling of old paper and expensive leather.

I collapsed onto the Persian rug, pulling Toby into my lap, gasping for air as the adrenaline began to wear off, leaving my limbs trembling violently.

Vincent leaned against the steel door, his chest heaving, listening for sounds of pursuit outside.

“We’re safe here,” Vincent panted, wiping blood from a shallow graze on his cheek. “The door is rated to withstand C4 explosives. They can’t get in without the code.”

He walked over to a massive oak desk in the center of the room and picked up a secure, hardlined red telephone.

He dialed a number rapidly.

“Marco,” Vincent barked into the receiver. “The estate is compromised. Rosalind is a Falcone. I need every loyal man you have converging on the mansion right now. Bring the heavy artillery.”

Vincent slammed the phone down.

He turned to me, his dark eyes softening as he looked at me and Toby huddled on the floor.

“You saved my life again, Sarah,” Vincent said quietly. “You’re incredibly brave.”

“I’m just a mother,” I breathed, stroking Toby’s hair.

“Mom,” Toby whispered, looking up at me, his eyes wide.

“What is it, baby?” I asked gently.

Toby pointed a trembling finger toward the far wall of the library.

“The bookshelves,” Toby said, his voice quivering. “They’re moving.”

I whipped my head around.

Vincent drew his pistol instantly, aiming it at the wall.

Toby was right. The massive, floor-to-ceiling bookshelf on the far side of the room was silently, slowly swinging outward on hidden hinges.
