"My three-year-old maid’s daughter secretly led me upstairs and showed me the woman I planned to marry threatening her mother and implying she could make the little girl disappear. Vivien thought no one important was listening, but she had made one mistake: the child knew exactly which man in that house everyone feared.

By dawn, the private chapel at the northern edge of the Duca grounds smelled of damp stone, frankincense, and freshly turned mortar.

Under the hollow marble pedestal of Saint Teresa, Rocco pulled back a lead-lined lockbox. Inside lay the red leather-bound diary of Isabella Duca, alongside three small amber glass vials wrapped in velvet.

Dr. Mercer, a sixty-year-old physician whose entire medical career had been funded and protected by the Duca family, adjusted his glasses under the glow of a portable halogen lamp. He used a micro-pipette to draw a residue sample from the rubber stopper of the smallest vial.

Five minutes passed in absolute silence. Only the sound of rain beginning to patter against the stained glass windows broke the gloom.

Mercer looked up, his face ghostly white.

"Thallium acetate," he breathed, his voice trembling. "Tasteless. Odorless. Soluble in water. It mimics chronic systemic neuropathy and progressive organ failure. In tiny micro-doses, it takes three to four months to shut down the heart. It wouldn't show up in a standard post-mortem panel unless someone specifically requested heavy metal chromatography."

Rocco cursed under his breath, his hand dropping instinctively to the heavy sidearm holstered beneath his leather jacket. "That witch killed Donna Isabella."

"She didn't act alone," I said, flipping through the delicate, yellowed pages of my mother's journal.

My mother’s handwriting, usually sharp and aristocratic, had deteriorated into erratic scrawls in the final entries. But her mind had remained tragically, heroically clear until the end.

*October 14th:*

*Vivien brought the chamomile again. She speaks of her father's firm, but her phone displays the crest of the Croft Syndicate. She thinks I am sleeping. I heard her speaking to Julian. They want the northern ports. If Lorenzo marries her, the Croft family gains immunity and maritime clearance.*

*November 2nd:*

*My legs will not hold me today. The girl watches me with dead eyes while she strokes my hair. She told me Lorenzo would be so lonely without me, but she would 'comfort' him. God preserve my son. He sees the world through honor, but these vipers see only blood.*

*November 20th:*

*Elena knows. I saw her hide the child behind the pantry when Vivien threatened to have them cast onto the streets. Vivien believes I gave Elena the master safe combinations. If she hurts that child, Lord strike her down. I leave the truth in the hands of Saint Teresa. Lorenzo will find it. My son never forgets a debt.*

I closed the book. The leather groaned softly in the quiet chapel.

Julian Croft.

The Croft family had been our rivals for thirty years—a faction built on human trafficking, illicit arms, and predatory debt. Three years ago, I had driven them out of the eastern seaboard, cutting their revenue by seventy percent. Croft had vowed vengeance, but I had expected car bombs, snipers, or boardroom coups.

Instead, he had sent a Trojan horse. A refined, polished sociopath trained to infiltrate my bedroom and poison my mother.

Rocco stepped forward, handing me a thick manila folder. "Our financial team spent the last three hours tearing into Vivien’s offshore entities. It's just like Isabella wrote. Vivien isn't an heiress. Her family went bankrupt five years ago. Julian Croft bought her father’s debt. In exchange, Vivien became Croft’s personal asset. If she secured your marriage, Croft was set to receive forty-nine percent of Duca Logistics through a pre-nuptial clause her lawyers drafted."

"The clause that gives her surviving power of attorney in the event of my 'incapacity'?" I asked coldly.

"Exactly," Rocco said. "She was going to poison you next, Lorenzo."

I looked at the altar, where the carved face of Saint Teresa looked down in silent sorrow.

"She thinks she's untouchable because she holds Elena and Mia hostage with fear," I said, my voice dangerously steady. "She thinks Elena will leave quietly today, taking the last potential witness with her."

"What do we do?" Rocco asked. "Take Croft down now? Throw Vivien into the harbor?"

"No," I replied, slipping the red diary into my coat. "That is too quick. That is too merciful. Vivien wants a wedding. She wants power. She wants to see Elena humiliated and crushed."

I turned toward the chapel doors as the gray morning light broke across the grounds.
