BOUND TO THE BILLIONAIRE'S VOW

THE WHISPER IN THE DARK

The sound was unmistakable.

A quiet, steady inhale, followed by an even slower exhale—like someone deliberately controlling their breathing to avoid detection.

Adrain didn’t move at first. He stood frozen, his head tilted just slightly, every nerve in his body listening. Bella could feel his grip on her tighten until her fingers ached. He didn’t need to say it; she understood. They were not alone.

The underground corridor suddenly felt smaller, the shadows heavier. The pipes above them hissed with escaping steam, masking subtle sounds but also making every creak of the floor under their feet more obvious.

Adrain shifted one foot forward, barely lifting it before placing it down soundlessly. Bella followed, mimicking his movements, afraid even her heartbeat would betray them. Her ears strained, trying to locate the source of that faint breath.

It came again—closer this time.

And then, a whisper.

Low. Hoarse. Almost like it was brushing against her ear despite the fact she saw no one nearby.

“Bella…”

She froze. Her mind scrambled to understand how anyone here could know her name. Her pulse quickened, sending a rush of heat through her chest.

Adrain’s voice was razor-sharp but controlled. “Don’t respond.”

They moved forward, his gun raised, his other hand steadying her behind him. The corridor ahead was darker now, the last functioning light flickering weakly before dying out completely, leaving them in near pitch blackness.

Bella’s vision blurred in the sudden darkness, and she instinctively gripped Damien’s jacket. She could still hear the whisper—soft, like it was moving along the walls themselves.

“You can’t hide…”

Her breath caught. “Adrain , they—”

A loud clang! erupted behind them. Bella spun around to see a heavy pipe swinging like a pendulum, striking the wall hard enough to send echoes racing down the tunnel.

It was a distraction.

Before Adrain could react, a shadow detached itself from the wall ahead and surged toward them. A flash of metal caught what little light remained.

Adrain fired once—sharp, controlled—but the figure ducked low, rolling to the side. Bella stumbled backward as the intruder’s boots splashed in a shallow puddle, the water rippling outward in silver rings.

For a moment, it was chaos: the hiss of steam, the slam of footsteps, and the faint whisper still curling through the air like a taunt.

Adrain stepped forward, putting himself between Bella and the shadow. His voice was cold now. “You have one chance to walk away.”

A laugh echoed, low and mocking. “Walk away? Adrain… you should know by now—I came here for her.”

Bella’s blood ran cold. The whisper hadn’t been random. They weren’t here for Adrain at all.

They were here for her.
