The Billionaire Hired Me as a Nanny to Save His Sick Heirs, But My Unborn Baby Whispered the Brutal Secret That Shook His Dynasty

The rain returned by late afternoon, beating against the nursery’s leaded windows like frantic fingertips. Ava sat on the floor beside the play mat where the quintuplets lay kicking their tiny legs in soft cotton sleepsuits. She checked their reflexes one by one, recording their progress in her leather-bound journal. They were healing rapidly; their lungs were clear, their skin supple and free of inflammation.

Mommy, Mason likes the music box, her baby whispered, warm and delighted. Turn the little gold key.

Ava smiled softly, winding the small Swiss music box resting on the low shelf. A gentle, cascading lullaby filled the quiet room. Mason immediately gurgled happily, his chubby fists waving in the air. Ava leaned forward, pressing her hands against her lower abdomen. The warmth radiating from within her was intoxicating—a psychic connection that defied every law of modern medicine she had spent seven years studying.

“Who are you?” Ava whispered softly to her unborn child. “How can you know these things?”

I am half of you, Mommy. And half of him. I hear the truth people try to hide in the dark.

A soft knock interrupted her thoughts. The door swung open, and Adrian walked into the nursery. He had discarded his suit jacket and tie, rolling up the sleeves of his white dress shirt to reveal strong, corded forearms. In the soft golden lamplight of the nursery, he looked less like an untouchable corporate titan and more like a weary guardian carrying the weight of a crumbling empire.

“The lab confirmed it,” Adrian said quietly, walking over to sit on the plush armchair beside the cribs. “Thallium sulfate. Enough in that bowl to induce total organ failure within forty-eight hours.”

Ava looked up from the floor, her heart aching for him despite his formidable exterior. “Did Beatrice confess?”

“She doesn't have to,” Adrian replied, his voice laced with bitter exhaustion. “Our security team found three vials of the compound in her vanity table, along with forged transfer documents assigning power of attorney over Sophia’s trust funds to Beatrice’s offshore shell company in the Cayman Islands.”

“Where is she now?”

“Under house arrest in the carriage house, guarded by four former federal marshals,” Adrian said. “Her passport has been seized. She won’t leave this property until the district attorney’s office finalizes the indictment.”

He paused, his gaze drifting over the five sleeping infants. A look of profound, aching sorrow passed over his chiseled features.

“Sophia’s late husband, David, was my closest friend,” Adrian murmured, staring at his hands. “When he died in that plane crash eight months ago, I promised him I would protect his legacy and his children. But my own family tried to slaughter them for an inheritance. My father married a viper, and I let her live under our roof.”

“You couldn't have known, Adrian,” Ava said gently, using his first name without thinking.

Adrian looked down at her, his gray eyes locking onto hers with a sudden, electric heat that made the room feel entirely devoid of oxygen. He slid out of the chair, dropping to one knee on the plush carpet right beside her.

“You called me Adrian,” he said softly.

Ava blushed furiously, looking down at the nursery floor. “I apologize, Mr. Foster. It was unprofessional.”

“Don't apologize,” he said, his voice dropping to a gravelly, intimate register. He reached out, his warm, strong fingers gently catching her chin and tilting her face upward until she had no choice but to meet his gaze. “Do you really think I didn't recognize you, Ava?”

Ava’s breath hitched. Her heart hammered against her ribs like a trapped bird. “What?”

“The Skyline Grand,” Adrian whispered, his eyes searching hers with breathtaking tenderness. “Suite 4402. You ran through my door like a wounded animal, trembling with fear, running from monsters in the hallway. I held you all night while the storm raged over the city. I woke up at dawn, and you were gone. No name. No phone number. Just the scent of jasmine and rain on my pillow.”

Tears welled in Ava’s eyes, spilling over her dark lashes. “You... you knew from the start?”

“The second you walked into that NICU at St. Catherine’s,” Adrian confessed, his thumb wiping away a tear from her cheek. “I wanted to pull you into my arms right there. But I saw the terror in your eyes, and I knew someone was still hunting you. I offered you this contract to bring you behind my walls, where I could keep you safe.”

Mommy, tell him, the baby urged, the voice vibrating with overwhelming emotion. Touch his hand to us. He needs to know he isn't broken.

Trembling, Ava took Adrian’s large, warm hand from her face and slowly guided it down, pressing his palm flat against her lower belly.

Adrian stiffened, his breath catching in his throat. Beneath his palm, a tiny, unmistakable pulse fluttered back—strong, steady, and alive with miraculous energy.
