The billionaire's six-year-old daughter hadn't spoken in a year, and every expensive specialist had failed her. But when I walked into that mansion wearing shoes held together with glue, I noticed something nobody else had. And the moment I raised my hands toward that little girl, her father froze.

"Back stairs," Marcus whispered immediately. He didn't hesitate. He pulled Lily into his arms, but she reached out, grabbing my wrist with a desperate strength.

"I'm with you, sweetheart," I told her softly, keeping my voice level, refusing to let her hear the terror clawing at my throat. "I'm not leaving you."

The mansion had transformed into a labyrinth of shadows. Without power, the third-floor corridor was illuminated only by the faint silver haze of the winter fog pressing against the high arched windows. The temperature seemed to plummet by degrees as the central heating died.

We hurried down the narrow service hallway toward the back stairs—the ones the maids used, uncarpeted and steep.

Suddenly, a door flew open ahead of us.

Marcus stepped forward, ready to strike, but the moonlight revealed a silk dressing gown and a shock of silver-blonde hair. Vivian stood in the threshold of her bedroom, holding an antique brass candlestick like a weapon.

"Marcus!" she hissed, her eyes darting between him, the child, and me. "The alarms just went dead, and there are two men in tactical gear in the front courtyard. What is going on?"

"Richard Vance," Marcus said bluntly, his voice cutting through her panic. "He killed Clara, Vivian. He bugged the house, he hired the security team you vetted, and he’s down in the foyer right now."

Vivian’s jaw dropped. The haughty, untouchable mask she wore crumpled into sheer horror. "Richard? No... I spoke to him this afternoon about the perimeter upgrades. He promised..." She looked at Lily, who shrank against Marcus’s neck, and the realization hit Vivian like a physical blow. Her hand flew to her mouth. "My God. The cameras. I thought they were for her protection."

"We don't have time for regret," I said, stepping forward and touching Vivian’s arm. "They're coming up the main staircase. Where does the basement archive lead?"

Vivian pulled herself together with astonishing speed. The aristocratic severity snapped back into her spine, but this time it was tempered with fierce protective fury. "The old wine cellar connects to the boiler room beneath the east wing. There's an exterior storm hatch that leads out into the rose garden near the carriage house."

"That's our way out," Marcus said. "Vivian, take the back stairs to the ground floor pantry. Grab the master keys from the hook behind the flour bin. Nora, stay behind me."

We moved in absolute silence. My father had taught me years ago how to walk without making a sound—rolling the weight from the outside edge of the heel to the ball of the foot, keeping the knees slightly bent. I took Lily's small, clammy hand in mine, guiding her footsteps along the baseboard where the floorboards were reinforced and didn't creak.

Lily looked up at me in the darkness. Even without light, her fingers moved against my palm, tapping out letters: *H-U-R-T?*

I tapped back against her tiny knuckles: *N-O. P-R-O-M-I-S-E.*

As we reached the landing of the second floor, heavy, measured footsteps echoed from the grand foyer below.

"Check the nursery first," a rough voice barked from the darkness below. "Mr. Vance wants the girl alive until we have the safe code. The nanny and the sister are collateral. Ellery goes down."

Marcus's jaw tightened. He gestured for us to press flat against the wall beneath an oil portrait of his grandfather.

Through the balusters of the upper gallery, I looked down into the grand foyer.

Standing beneath the unlit chandelier was Richard Vance. He wore an expensive wool overcoat, but in his right hand, gleamed the dull matte black of a silenced handgun. Beside him were two broad-shouldered men in dark tactical jackets, sweeping the corners with high-intensity flashlights.

"Marcus!" Vance called out, his voice echoing off the limestone walls with mocking familiarity. "Don't make this messy in front of the child. Just hand over the key to the archive, and I'll make sure Lily goes to a very nice, very quiet boarding school in Switzerland. She already knows how to keep her mouth shut."

Behind me, I felt Lily stiffen.
