33 "The Midnight Return: How a Mafia Boss Unmasked His Fiancée’s Treachery and Saved His Family's Legacy"

The basement archives of the Mercer estate were rarely visited by sunlight. Built deep into the rocky Newport coastline over a century ago, the subterranean rooms were lined with floor-to-ceiling mahogany bookshelves filled with ledgers, maritime shipping logs, land grants, and private family trusts dating back to the Gilded Age.

The air down here always smelled of old paper, cedar, and damp stone. Tonight, however, it smelled of impending war.

Emma hurried down the winding stone staircase carrying a heavy thermos of black coffee and two ceramic mugs. Her footsteps echoed off the vaulted brick ceiling. When she reached the central vault room, she found Dominic seated at the massive oak partner’s desk, the green-shaded banker’s lamp casting a harsh, theatrical glow over his chiseled face.

He had shed his damp coat, leaving him in a charcoal dress shirt with the sleeves rolled up to his elbows, revealing the corded muscle of his forearms and the faint, jagged scar running across his left wrist—a souvenir from a hostile dockyard dispute in his twenties.

“Set it down anywhere,” Dominic said without looking up from the laptop screen glowing brightly before him. A cascade of green code and financial spreadsheets reflected off his dark eyes.

Emma quietly placed the tray on the edge of the desk, pouring a cup of coffee and sliding it toward him. “The guest wing is locked, Mr. Mercer. I checked the interior sensors. Brooke went back to her suite on the third floor ten minutes ago. She hasn't tried to use the landline, but her cell phone has been connecting to an outside tower every forty seconds.”

Dominic took the coffee mug, his fingers brushing against the ceramic. He finally leaned back in his leather chair, rubbing the bridge of his nose with a look of profound exhaustion. “She’s calling her father. Arthur Harrington doesn't sleep when he smells blood in the water. He thinks because he helped finance my shipping fleet five years ago, he owns a controlling stake in my personal life.”

“Is he a threat to the estate?” Emma asked softly, standing respectfully near the edge of the desk.

Dominic let out a dark, dry chuckle. “Arthur is a shark in a pond full of goldfish. But he forgets who owns the ocean.” He tapped the side of the laptop. “What concerns me isn't Arthur. It’s what Brooke managed to sign off on while I was in London dealing with the European syndicate.”

Emma stepped a little closer, her eyes scanning the open files on the screen. “You think she had help inside the estate?”

“People don't steal a trust deed with just a pen and a dream, Emma,” Dominic said, his voice dropping into a dangerous, analytical register. “To execute a probate transfer in Rhode Island without my signature, she needed a notary with clearance, a compromised family lawyer, and an internal proxy to bypass the estate’s digital security firewall.” He looked up at her, his dark eyes piercing. “And according to the server logs, the proxy access code used to download my mother’s original will at 3:14 AM on Tuesday… came from the secondary terminal in the east wing library.”

Emma’s breath caught. “The east wing library? But nobody goes in there except—except for Natalie when she’s looking for children’s books with Noah, or…” She trailed off, her eyes widening.

“Or my personal legal secretary, Marcus Vance,” Dominic finished for her.

The name hung in the damp air like a thunderclap. Marcus had been with the Mercer family for eight years. He had managed Dominic’s personal accounts, attended family dinners, and even played catch with Noah on the lawn. If Marcus had flipped—if Brooke’s family had bought him off with promises of a partnership in Boston—then the betrayal wasn't just at the perimeter; it was rotting from the core.

“Where is Marcus right now?” Emma asked, her voice dropping to a whisper.

“Asleep in his quarters above the carriage house,” Dominic replied smoothly, standing up from the desk. He reached into his shoulder holster, pulled out a matte-black Sig Sauer P226, and checked the magazine with a sharp, metallic click that echoed off the stone walls. He slid the weapon back into its leather housing beneath his arm. “Not for much longer, though.”

“Dominic, wait,” Emma said, stepping in front of him before he could march toward the basement exit. “If you confront Marcus now without proof, he’ll lawyers up, and Brooke will claim you’re harassing her guests before the wedding. You need more than server logs. You need a trap.”

Dominic paused. He looked down at Emma, studying her face in the dim amber light. For three years, Emma had managed the chaotic, high-pressure household of a billionaire mafia boss with the poise of a diplomat and the instincts of a survivor. She knew every secret, every buried grudge, and every skeleton rattling inside the Mercer family closet.

“A trap?” Dominic’s lips curved into a faint, dangerous smile. “And what do you suggest, Emma?”

“Brooke thinks you’re still suspicious, but she doesn't know you found the quitclaim deed in her folder tonight,” Emma explained quickly, her mind racing. “She thinks you just stumbled on a minor dispute. If you leave the estate again at dawn—make a loud, public departure pretending you have an emergency meeting in Boston—she and Marcus will think the coast is clear to finalize the digital transfer of the trust before the weekend.”

Dominic crossed his arms over his chest. “And when they try to execute the transfer…”

“The secondary terminal will lock automatically,” Emma finished, her eyes gleaming with determination. “We route the terminal through a secure sandbox server that mirrors the probate court’s database. The moment Marcus hits ‘Submit’ on the fraudulent transfer, it triggers an un-deletable digital signature straight to the FBI’s financial crimes division and federal district court.”

Dominic stared at her for a long, silent moment. Then, slowly, a low laugh rumbled in his chest—a genuine, dark sound that hadn't escaped him in months.

“You’re a terrifying woman, Emma Collins,” Dominic said softly, stepping past her toward the stairs. “Remind me never to get on your bad side.”
