Chapter 4 - The Mechanic in the Walls

I pulled Hunter and Leo behind me.
The vent cover crashed to the floor.
Caleb Mercer dropped from the opening and landed hard on one knee.
He looked thinner than the photograph in his employee record. His beard was uneven, his jacket torn, and dried blood darkened one sleeve.
Three of my guards aimed weapons at him.
Caleb raised both hands.
“If you shoot me, Sophia’s killer walks free.”
Hunter stepped around me.
“You said Lily’s name.”
“Hunter—”
She struck him across the face.
No one stopped her.
Caleb absorbed the blow without defending himself.
“You don’t get to say her name,” she whispered.
“I know.”
“You left me bleeding on those stairs.”
“I panicked.”
“You stepped over me.”
His eyes dropped.
“Yes.”
Hunter would have hit him again, but Leo began crying against her shoulder.
She turned away.
I ordered the guards to search Caleb.
They found a storage key, a disposable phone, and a memory card sealed inside a plastic bag.
“What is on this?” I asked.
“Not enough,” Caleb said. “The rest is in a locker at Penn Station.”
“Start talking.”
He looked toward Vincent’s private guards at the far end of the corridor.
“Not here.”
I dismissed everyone except two men who had served me before Vincent entered the family business.
Inside the clinic office, Caleb told us what happened on the night Sophia died.
Vincent had hired him to install a tracking device beneath our car.
Caleb claimed he had not known about the bomb.
“He said you believed someone was following Sophia,” Caleb explained. “I thought it was security work.”
“You accepted fifty thousand dollars to attach an unregistered device without telling me.”
“I knew it was wrong. I didn’t know she would die.”
“What did you see?”
“Two men entered the garage after I finished. One carried a metal case. I got suspicious and left my diagnostic camera running beneath the dashboard.”
“Why?”
“Insurance.”
Cowards often called evidence insurance when what they meant was leverage.
“The camera transmitted to a storage module,” Caleb continued. “After the explosion, Vincent’s people started looking for me. I stole the module and ran.”
Hunter stared at him.
“You came home.”
“I needed money.”
“You came home and found me packing.”
Caleb closed his eyes.
Hunter had discovered the cash and a newspaper report about Sophia’s death. She threatened to call the police.
Caleb grabbed her phone.
She fought back.
He pushed her.
“I didn’t know she was so close to the stairs,” he said.
“You knew I was pregnant.”
His voice broke.
“Yes.”
No apology could carry the weight of that answer.
I wanted him dead.
Not later.
Not after a trial.
In that moment, I understood exactly how easy it would be to order his body removed and forget he had ever entered my house.
Hunter saw the decision on my face.
“If you kill him, you become useful to Vincent,” she said.
I looked at her.
“He deserves justice,” she continued. “Not disappearance.”
The word cut through me.
Sophia had once used the same argument.
She had spent years trying to pull me away from the violent instincts my father taught me. After her death, I returned to them completely.
Perhaps that was what her killer expected.
I lowered my weapon.
Caleb gave us the locker key.
We left the mansion through an old wine-cellar tunnel built during Prohibition. Hunter refused to remain behind, and Leo could not be separated from her without distress, so Dr. Keller accompanied them in an armored vehicle.
Penn Station was crowded enough to make an ambush difficult and private enough to make one inevitable.
The locker contained a black case.
Inside were the dashboard storage module, payment records from North Harbor Medical Services, and copies of messages between Caleb and a contact identified only as V.
One message had been sent an hour before Sophia’s death.
Tracker active. She leaves gala at 11:10.
Another arrived afterward.
The younger brother survived. Fix the hospital problem before he remembers.
I read it twice.
“What hospital problem?”
Caleb looked at Hunter.
“When you fell, I called Vincent.”
Her face twisted with disgust.
“I was afraid you would wake up and tell the police,” he said. “Vincent sent Dr. Halloran to the hospital.”
Hunter stopped breathing.
“What did he do?”
“I don’t know. He said he would keep you quiet.”
Dr. Keller took the medical papers from the case.
“These are Lily’s records.”
Hunter nearly dropped Leo.
The report claimed she arrived at the hospital more than two hours after the emergency call.
“That’s false,” she said. “The ambulance came immediately.”
Another document showed that surgery had been delayed because an outside physician advised staff that Hunter was unstable and may have caused her own injuries.
The physician was Julian Halloran.
Dr. Keller’s voice became quiet.
“An emergency delivery might have saved Lily.”
Hunter bent over as though someone had struck her.
Caleb reached toward her.
I caught his wrist.
“Do not touch her.”
A man in a maintenance uniform appeared near the end of the corridor.
He raised a gun.
Caleb saw him first.
He shoved Hunter and Leo behind the lockers.
The shot struck Caleb in the chest.
My guards returned fire as commuters screamed and scattered.
The attacker disappeared into the crowd.
Caleb slid down the wall.
Hunter stared at him, shock replacing anger.
He pressed the memory card into my hand.
“The camera caught their voices,” he whispered. “Sophia knew.”
“Knew what?”
Caleb coughed.
“She knew Vincent was stealing from the foundation. She confronted him at the gala.”
His eyes moved toward Hunter.
“I’m sorry about Lily.”
She said nothing.
There was nothing left to say.
Caleb died before the paramedics reached us.
Back at the estate, my technicians restored the dashboard recording.
Most of the video showed darkness and the underside of the car.
The audio was clear.
Sophia’s voice came first.
She was speaking to someone in the garage before joining me at the gala entrance.
“I found the transfers, Vincent. Children’s hospitals, maternity clinics, pension funds—you used all of them.”
Vincent answered calmly.
“You do not understand what keeps this family alive.”
“I understand theft.”
“You married a man who built his life on blood.”
“And I am trying to save him from becoming you.”
There was a pause.
Then Sophia said the words that changed everything.
“Tomorrow, I’m giving Lorenzo the audit. And I’ve changed Leo’s trust. If anything happens to me, you lose control of every Rossi company.”
Vincent’s voice became very soft.
“Then nothing can happen to you.”
The recording ended thirteen minutes before the explosion.
I looked toward the library door.
Vincent stood there with six armed men.
He slowly applauded.

“You were always stubborn, little brother,” he said. “Sophia made you sentimental.”
Then every light in the mansion went out.
