He Hired a Curvy Security Expert to Test His Mansion—By Noon, She Had Broken Into the Mafia Boss’s Home

The command room was no longer a place of corporate security audits. It had become a war room.

Marco had stripped off his suit jacket, rolling his crisp white sleeves up his muscular forearms, revealing the intricate black ink of dragons and thorns that wound their way up to his wrists. He leaned over the primary terminal, his face illuminated by the cold blue light of the digital schematics.

"The transponder was planted within the last thirty-six hours," Cal reported, pulling up the power draw logs. "Whoever put it there knew our auxiliary circuit had a blind spot during the scheduled Tuesday backup cycle."

"An insider," Marco said, his voice quiet, flat, and absolute.

Tessa stood beside him, her arms crossed over her chest. She had pulled her hair into a tighter, no-nonsense ponytail, and she was studying the network topology with the intensity of a surgeon.

"Not necessarily an insider on your personal payroll," Tessa corrected, pointing a well-manicured finger at a junction node on the screen. "Look at the installation technique. See the crimp on that fiber splice? That’s not a hurried job done by a traitor sneaking around in the dark. That’s utility contractor work."

Marco turned to look at her. "Explain."

"Three days ago, you had the municipal fiber line repaired outside the south perimeter gate after a city water main break," Tessa said, her voice crisp and authoritative. "Your men checked the contractor's credentials. They checked the van. They probably ran background checks on the two technicians."

Cal blinked. "We did. Both clean. Union guys, thirty years in the city."

"The guys were clean, but their equipment wasn't," Tessa said, tapping the glass. "Someone intercepted their supply depot, replaced the standardized junction box with an altered unit pre-loaded with this transponder, and waited for your city contractors to do the dirty work for them. They didn't need to break in. You invited them to the curb."

Cal stared at the screen, then slowly cursed under his breath. "That’s surgical."

Marco didn't curse. He looked at Tessa, his eyes narrowing in cold calculation. "You recognized that splice instantly."

"I consult for government defense infrastructure when I'm not babysitting arrogant billionaires," she replied without missing a beat. "The Moretti family didn't design this. They bought it. And whoever sold it to them gave them a backdoor that bypasses your entire early warning array."

Marco reached for his tactical radio on the console. "Cal. Lock down the estate. Move the external patrols to defensive perimeter delta. Nobody leaves. Nobody enters."

"Understood," Cal said, turning toward the door.

"Wait," Tessa said sharply.

Marco froze, his hand still on the radio. He looked down at her, towering over her with all the coiled menace of a predator interrupted. "I don't pause during tactical emergencies, Ms. Morgan."

"If you lock down the estate right now, you tell them you found the beacon," Tessa said, not yielding an inch. She stepped right into his space, her eyes flashing fiercely. "The beacon pings every ninety seconds. If the host circuit cuts out, the signal dies. The Morettis will know their window is closing, and they won't wait for nightfall. They’ll hit you while your guards are still shifting positions."

Marco held her gaze. The silence between them was suffocating.

"You're advising me on tactical operations now?" he asked softly.

"I'm advising you on how not to get us killed," she countered, her chin lifted high. "You paid for an audit. Well, congratulations, Mr. Duca: you have an active hostile penetration in progress. Do you want to play tough guy, or do you want to catch the bastards who did it?"

Cal cleared his throat quietly from the doorway. "She has a point, boss."

Marco stared down at Tessa for three long, agonizing seconds.

He was used to people cowering before his anger. He was used to captains twice her size stuttering when his tone dropped to a whisper. But this woman—with her curves, her sharp tongue, and her brilliant, relentless mind—stood right in front of him, challenging him like an equal.

A slow, dangerous spark lit behind Marco’s dark eyes.

"Cal," Marco commanded, never breaking eye contact with Tessa. "Leave the circuit live. Feed the transponder a loop. Fake the telemetry so it looks like the estate is operating on normal low-alert status."

"On it," Cal said, his fingers immediately flying across the keyboard.

Marco stepped closer to Tessa, his voice dropping to a gravelly murmur. "You're off the clock, Ms. Morgan. My driver will take you through the north service gate. You’ll be in a safehouse across state lines within two hours."

Tessa’s eyebrows arched in absolute disbelief. "Excuse me?"

"You're a civilian."

"I am the security consultant who just diagnosed the weapon pointed at your head."

"And your contract is concluded," Marco said, his jaw tightening. "This is no longer a simulation. Lorenzo Moretti doesn't leave witnesses. When his men come through that perimeter, it won't be with clipboards and yellow folders. It will be with suppressed carbines and incendiary charges."

"Then you'll need someone who can override their electronic jammer when they blow your main grid," Tessa shot back, crossing her arms stubbornly. "Because that’s what this beacon does, Marco. It’s not just a tracker. It’s an EMP capacitor. When they trigger it, your entire automated defense grid goes dark for forty-five seconds."

Marco paused, his gaze sharpening. "Forty-five seconds."

"Forty-five seconds is a lifetime in a firefight," she said coolly. "I can isolate the capacitor and reverse the surge into their receiver. But I need ten minutes at the junction box on the south wall."

Marco studied her face. He saw no terror. He saw no trembling hands. What he saw was raw, unadulterated competence wrapped in a woman who was rapidly becoming the most dangerous thing in his life.

"If you stay," Marco murmured, leaning down so his lips were inches from her ear, "you take orders from me. No detours. No jokes. No stolen fruit."

Tessa felt a shiver run down her spine at the heat of his breath against her skin. Her pulse hammered against her ribs, but she held her ground, looking straight into his dark, lethal eyes.

"I only take orders when they make sense, Duca."

A ghost of a smirk touched Marco’s lips. "We'll see about that."

He reached into his shoulder holster, pulled out a compact, matte-black Glock 43X, and checked the chamber with a smooth, practiced flick of his wrist. He turned it around and held it out to her, grip first.

"Do you know how to use this?"

Tessa took the weapon. Her grip was flawless; her index finger rested instantly along the frame, well clear of the trigger guard. She dropped the magazine, checked the brass casing of the top round, snapped it back into place, and racked the slide with effortless muscle memory.

"Trained by Israeli private defense contractors in Tel Aviv," she said mildly. "Center-mass groupings at twenty-five yards."

Marco watched her handle the firearm, and for the first time in forty-eight hours, an authentic, dangerous smile spread across his face.
