BANG! BANG! BANG!

Five-year-old Harper Collins pounded her tiny fists against the basement door.

Tears streamed down her cheeks.

"Daddy! Daddy, come here!"

Her father, Michael, hurried down the hallway.

"Harper? Sweetheart, what's wrong?"

The little girl grabbed his hand and pulled him toward the locked door.

"Daddy, Mommy's down there!"

Michael froze.

His wife, Rachel, had disappeared ten months earlier after her car was found near a flooded river. Everyone believed she'd died in the accident, although her body had never been recovered.

Four months ago, Michael had married Evelyn, a woman who had helped him care for Harper during those painful months.

"Harper, honey," he whispered, kneeling beside her. "Mommy isn't coming back."

But Harper shook her head desperately.

"No! Mommy's crying! I heard her!"

Before Michael could answer, a faint voice came from beneath the door.

"Michael..."

He stopped breathing.

The voice was weak and barely audible.

But he knew it.

"Rachel?"

Harper squeezed his hand.

"See, Daddy? I told you!"

Then the voice whispered again.

"Please... help me."

Michael stared at the locked basement door.

His wife was alive.

And someone had been hiding her beneath their home.

Chapter cliffhanger: Before Michael could open the door, Evelyn appeared behind them.
