At two in the morning, a six-year-old girl pushed a vacuum twice her size across a mafia boss's private study, her baby sister asleep against her back in a knotted shawl. She wasn't scared of him.

Claire Vancura was the younger sister of Dominic Vancura—the ruthless head of the North End syndicate, Roman’s bitterest rival, and the man who had tried to take Roman's life four separate times over the last decade.

Seven years ago, Claire had vanished. Word on the street was that Roman's crew had eliminated her during the warehouse war of 2019. It was the lie Dominic Vancura had used to unify the northern families against Roman, fueling a bloody turf war that had cost dozens of lives.

Now, she was sitting inside the wall of Roman's private home, thin as a ghost, her eyes sunken, holding a military listening device.

"How long have you been in here, Claire?" Roman asked, his voice dead calm as Silas stepped inside the narrow shaft and secured her hands with tactical zip-ties.

"Eight... eight months," Claire wept silently, her thin body trembling as Silas lifted her off the iron stool. "Dominic... he put me in here. He didn't kill me... he kept me in the tunnel system beneath the old docks... then he found the access shaft from the storm drains under Beacon Hill..."

Roman felt a cold fury igniting in his gut.

The historic mansions of Beacon Hill were famous for their underground networks—smuggling tunnels constructed in the 18th century that connected the old cellars directly to the Charles River waterfront. Roman had sealed his basement doors with three inches of reinforced steel, but he had never surveyed the abandoned brick air-shafts running between the double-plaster walls of the upper floors.

Dominic Vancura hadn't just been guessing Roman’s moves. He had been sitting inside Roman’s house, listening to every phone call, every meeting, every strategy session Roman had held in his private study for nearly a year.

"Why were you scratching the wood?" Roman demanded, kneeling beside her on the cold brick floor.

"Because... because I wanted someone to hear me," Claire sobbed, pressing her bleeding fingers against her coat. "Dominic comes through the lower drainage hatch every three days to bring water and collect the audio drives. He told me if I made a noise... he’d kill my daughter. But I couldn't take it anymore. The dark... the cold... I knew if I scratched near the desk at three, whoever was cleaning might hear..."

Roman stared at her.

Mia.

A six-year-old girl with a baby strapped to her back had heard what fifteen elite security guards and two million dollars of electronics had missed.

"Silas," Roman snapped.

"Yeah, Boss?"

"Get her down to the private medical wing in the basement. Put two men on her door. Don't touch her, don't let her speak to anyone, and treat those hands."

"What about the tunnel?" Silas asked, pointing his flashlight down into the deep, vertical drop where rusted iron ladder rungs disappeared into the darkness below.

"Call Dante and the heavy team," Roman ordered, his eyes turning to flint. "We’re going down."

Before Roman could step out of the passage, a faint sound echoed up through the vertical brick shaft from fifty feet below.

A metallic click. The sound of an iron grate being unlatched.

Dominic Vancura’s pickup team was early.

Roman drew his Kimber .45, looking back at the clock in his study.

It was 3:05 AM.

"Silas, take Claire out now," Roman whispered, pressing himself against the damp brick wall of the hidden passage. "Tell Dante to bring the heavy gear to the basement drainage vault. Tonight, we end the Vancuras."

As Silas led the weeping woman into the study, Roman reached down, grabbed the tactical radio Claire had dropped, and slipped it into his pocket. He took a deep breath of the stale, cold air, listening to the muffled footsteps climbing the iron ladder from the dark depth below.
