Chapter 1 - The Three KnocksThe Child Who Heard What No Adult Could Hear

At two in the morning, I discovered a six-year-old girl cleaning my private study with a baby strapped to her back.
She was terrified her mother would lose her job.
She was far more terrified of disappointing me.
But neither fear explained why she suddenly stopped pushing the vacuum, turned toward my library wall, and whispered the strangest question I had ever heard in my own home.
“Mr. Duca... why does someone keep knocking from inside there?”
I had spent the entire evening in a glass tower downtown, stopping three powerful men from making a decision that could cost my company eighty million dollars.
At 1:47 a.m., all I wanted was silence.
Instead, when I entered my Beacon Hill house, I heard a vacuum running upstairs.
Wrong hour.
Wrong floor.
I took the service stairs, following the uneven mechanical whine.
Start.
Stop.
Start again.
A narrow line of warm light escaped beneath the door of my private study.
I stopped.
Nobody entered that room without my permission.
I pushed the door open.
The vacuum stood crooked beside the bookshelves.
My desk lamp was on.
And a tiny girl was standing beside my desk, dragging a wet cloth over the leather blotter.
Her cheeks were pink from the cold.
Her small hands were red.
A sleeping baby was strapped securely across her back in a faded blue shawl.
I knew her.
Mia Harper.
Six years old.
Her mother, Grace, had worked for my household for eight years.
Eight years.
And I suddenly felt ashamed that I had known the exact number of rooms in my house but almost nothing about the woman who cleaned them.
Mia saw me.
She froze.
The cloth slipped from her hand.
For a second, neither of us moved.
Then she whispered, “Please don't be angry.”
“I think that's going to depend on why you're here.”
Her eyes immediately filled.
“My mama is sick.”
“Where is she?”
“She told me to finish.”
“You're cleaning my study at two in the morning?”
She nodded.
“Why?”
She looked down.
Then she glanced toward the sleeping baby.
“Because we need the money.”
My stomach tightened.
“What's the baby's name?”
“Lily.”
“She your sister?”
Mia nodded.
“She doesn't wake up much when I carry her.”
I stared at the child on her back.
The sight bothered me more than it should have.
“Take off the vacuum,” I said.
Mia's eyes widened.
“I'll finish first.”
“You don't have to finish.”
“But if I don't...”
She stopped.
“...what?”
“My mama said Mr. Duca might be angry if the work isn't done.”
Something inside me went cold.
I had never said that.
Not once.
“Who told your mother that?”
Mia hesitated.
“I don't know.”
“Where is Grace now?”
“At home.”
“She sent you here alone?”
“She was too sick to come.”
My anger rose.
Not at Mia.
At the absurdity of what I was seeing.
A six-year-old carrying an infant through a mansion at two in the morning because an employee was frightened of losing her job.
I stepped closer.
Mia instinctively moved backward.
“I'm not going to hurt you.”
She nodded.
But she didn't believe me yet.
Then she turned her head.
Her expression changed.
She was no longer watching me.
She was staring at the library wall.
“What?”
She whispered, “Listen.”
I listened.
Nothing.
The house seemed completely dead.
Then Mia pointed toward the shelves.
“That's where it happens.”
“What happens?”
“The knocking.”
I almost laughed.
Instead I heard myself ask, “What knocking?”
She moved closer to the wall.
“Mama says I'm imagining it.”
“Why would you imagine knocking?”
“I don't know.”
“How many times?”
She raised three fingers.
“Usually three.”
I looked at the wall.
It was an enormous floor-to-ceiling bookcase made from walnut, built into the room more than forty years ago.
Behind it should have been solid masonry.
I knew that because I'd once renovated the study.
“There is nothing behind that wall.”
Mia frowned.
“Then why does it answer?”
I stared at her.
“What do you mean, answer?”
She pointed toward the books.
“Sometimes I knock.”
I felt an involuntary chill.
“You knock?”
“When I'm scared.”
“And what happens?”
She swallowed.
“Someone knocks back.”
I stepped toward the bookcase.
Mia caught my sleeve.
“Don't.”
I looked down at her hand.
“Why?”
Her voice dropped to almost nothing.
“Because Mama told me never to knock back.”
Before I could ask anything else, a sound traveled through the wall.
Very faint.
Very slow.
Knock.
Knock.
Knock.
Mia pressed her face against my arm.
I didn't move.
Every instinct I had developed in twenty years of business told me to search the room, identify the source, find the mechanism.
But there was no mechanism.
No speaker.
No pipe.
No obvious access.
The sound came from behind the books.
I stepped closer.
Another three knocks.
This time louder.
Knock.
Knock.
Knock.
I reached toward the shelf.
Mia grabbed my wrist.
“Mr. Duca.”
“What?”
“Don't open it.”
“Why?”
She looked at me with the solemn certainty only a frightened child could possess.
“Because last time Mama heard it, someone disappeared.”
The words landed harder than any accusation.
“Who disappeared?”
Mia's eyes moved to the hallway.
She lowered her voice.
“My daddy.”
I stared at her.
Grace had told me years ago that her husband, Caleb Harper, had died in a construction accident.
A tragic accident.
That was all I knew.
But before I could ask another question, the baby on Mia's back stirred.
Lily whimpered.
Mia turned instantly.
“Shh. It's okay.”
I looked at the wall.
Another sound came from inside.
Not three knocks this time.
One.
Then two.
Then one.
Mia went completely pale.
“What does that mean?”
She whispered the answer.
“That's not the knocking.”
“What is it?”
She lifted her eyes to mine.
“That's the warning.”
And from somewhere deep inside my library wall, a man's voice whispered my name.
“Duca.”
I stopped breathing.
May you like
Mia screamed.
The lights went out.
