PART 2

Knock.

Knock.

Knock.

The sound was soft.

Almost polite.

That made it worse.

I stared at the library wall while Mia stood beside my desk with one hand resting protectively against the sleeping baby on her back.

For years, I’d made a living noticing what other people missed.

A hesitation before a signature.

A glance exchanged across a conference table.

The subtle change in someone’s voice when money stopped being theoretical and became personal.

Yet I had lived in this house for eleven years and had never noticed anything unusual about that wall.

“Does it always come from there?” I asked.

Mia nodded.

“Usually when the house is quiet.”

“How often?”

She considered the question seriously.

“Three nights this week.”

I turned toward her.

“You’ve been here three nights this week?”

Her expression immediately closed.

I realized too late what my question sounded like.

“Mia.”

“Please don’t be mad at Mama.”

“I’m not angry with your mother.”

“You look angry.”

Apparently six-year-olds were less intimidated by my reputation than corporate boards.

I exhaled.

“That’s just my face.”

She studied me.

“Do you always have that face?”

Despite myself, I almost smiled.

“Frequently.”

Another faint sound came from the wall.

Not knocking this time.

A scrape.

Mia moved closer to the desk.

I looked at her and then at the baby.

Whatever was behind that bookcase could wait.

A six-year-old cleaning a house at two in the morning could not.

“Where is your mother now?”

“Home.”

“Alone?”

“She’s sleeping.”

“And she knows you’re here?”

Mia looked at the floor.

That answered the question.

I pulled my phone from my coat.

Her head snapped up.

“Who are you calling?”

“Someone who can help.”

“Are you calling the police?”

“No.”

“My mama didn’t do anything.”

“I know.”

She didn’t look convinced.

I called Elena Russo.

Elena had managed my household for twelve years, which meant she knew where everything was, remembered everything I forgot and possessed the unusual ability to tell me I was wrong without ever raising her voice.

She answered on the fourth ring.

“Dominic?”

“I need you at the house.”

A pause.

“It’s two in the morning.”

“I am aware.”

“Is something wrong?”

I looked at Mia.

“Yes. But not the kind you’re thinking.”

Elena arrived twenty-three minutes later wearing a long wool coat over pajamas and carrying the expression of a woman preparing to discover that I’d somehow set fire to my own kitchen.

Instead, she found Mia sitting at the breakfast table wrapped in a blanket, drinking warm milk while Lily slept in a portable bassinet I’d discovered in a storage closet.

Elena stopped.

“Oh.”

Mia immediately said, “Mama didn’t send me.”

Elena’s face softened.

“I know, sweetheart.”

“You won’t tell him to fire her?”

Elena looked at me.

“No one is being fired.”

Mia’s shoulders dropped slightly.

I leaned against the kitchen counter.

“Grace is ill. Mia left home and came here because she thought the work needed to be done.”

Elena looked horrified.

“By herself?”

Mia shook her head.

“I brought Lily.”

Elena closed her eyes for a moment.

Apparently that distinction did not improve matters.

“How did you get inside?” I asked.

Mia produced a brass key from her sweater pocket.

“Mama’s.”

Of course.

Grace had worked in the house long enough to have a service entrance key.

“Does your mother know you took it?”

Another examination of the floor.

“No.”

Elena sat beside her.

“Mia, your mother is going to be frightened when she wakes up and doesn’t find you.”

“I left her a note.”

“What did it say?”

Mia thought.

“‘Don’t worry. I’m doing your work. Lily is with me.'”

Elena looked at me again.

I reached for my coat.

“We’re taking them home.”

Mia’s face changed.

“But I didn’t finish.”

“The dust will survive until morning.”

“But—”

“Mia.”

She fell silent.

I softened my voice.

“Your mother’s job doesn’t depend on whether my desk is polished tonight.”

She watched me cautiously.

“Promise?”

I couldn’t remember the last time someone had asked me for a promise and expected the word itself to mean something.

“I promise.”

She nodded.

Then she glanced toward the ceiling.

“Are you going to see who’s knocking?”

“Tomorrow.”

“What if they’re lonely?”

I looked at her.

That question followed me all the way to Grace Harper’s apartment.

Grace lived in Dorchester, in a narrow brick building above a laundromat.

The stairwell smelled faintly of detergent and somebody’s late-night cooking.

Elena carried Lily.

I carried Mia because she’d fallen asleep in the car despite insisting she wasn’t tired.

She weighed almost nothing.

That bothered me more than it should have.

We reached the third floor.

Mia woke enough to point.

“That one.”

The apartment door was unlocked.

Inside, a lamp burned beside a worn sofa.

Grace Harper was asleep beneath a blanket.

Or unconscious.

For one terrible second, I couldn’t tell.

Elena hurried to her.

“Grace?”

Grace stirred.

Her eyes opened slowly.

Then she saw me.

Confusion crossed her face.

Then Elena.

Then Mia in my arms.

She sat up so quickly she became dizzy.

“Mia?”

“I’m okay, Mama.”

Grace stared at her daughter.

Then at Lily.

Her face went pale.

“What happened?”

“Mama—”

“What happened?”

“Mia came to my house,” I said.

Grace froze.

The silence that followed was different from the silence in my study.

This one was filled with shame.

She tried to stand.

Her knees nearly gave way.

Elena caught her.

“You have a fever.”

“I’m fine.”

“You are obviously not fine.”

Grace looked at me.

“Mr. Duca, I can explain.”

“No explanation tonight.”

“I should have called.”

“Yes.”

Her face tightened.

“I know.”

“I didn’t mean—”

“Grace.”

She stopped.

“You are sick. Your children are exhausted. Whatever conversation you think we’re going to have can happen tomorrow.”

She looked almost frightened by that.

“Am I still employed?”

I thought about Mia pushing the vacuum.

“Yes.”

Grace closed her eyes.

Relief moved through her so visibly that I had to look away.

Elena began organizing the room as if she’d lived there for years.

Water.

Medicine.

Clean blankets.

She called an overnight medical service and arranged for someone to check Grace’s fever.

I stood uselessly near the door.

There were photographs everywhere.

Mia missing two front teeth.

Grace holding newborn Lily.

A man with kind eyes standing beside Grace in front of a small Christmas tree.

In another photograph, he wore a carpenter’s belt.

I looked more closely.

Something about him seemed familiar.

Grace noticed.

“That’s my husband.”

“Where is he?”

Her eyes dropped.

“He died four years ago.”

“I’m sorry.”

She nodded.

“His name was Daniel.”

I looked at the photograph again.

Daniel Harper.

The name meant nothing.

Yet the face did.

I couldn’t place it.

I left twenty minutes later after the doctor arrived.

Before I stepped through the door, Grace called my name.

“Mr. Duca?”

I turned.

She was sitting on the sofa, Mia curled beside her.

“Thank you for bringing them home.”

I nodded.

Then Mia opened one sleepy eye.

“Don’t forget the knocking.”

Grace went completely still.

I noticed.

“You’ve heard it too,” I said.

“No.”

Her answer came too quickly.

Mia frowned.

“But Mama—”

“Go to sleep, sweetheart.”

I watched Grace.

She wouldn’t meet my eyes.

For the first time that night, the mystery in my library became more than an architectural curiosity.

Grace Harper knew something.

I returned to Beacon Hill shortly after three.

Elena insisted on coming back with me.

“You should sleep,” she said.

“So should you.”

“I would be sleeping if someone hadn’t called me.”

“Send me an invoice.”

“I already do.”

We entered the study.

The abandoned cloth remained on the desk.

The vacuum stood crookedly beside the rug.

Elena looked around.

“Where did Mia hear it?”

I pointed.

“The library.”

The bookcase occupied nearly the entire north wall, built from dark walnut and reaching almost twelve feet to the ceiling.

I’d bought the house furnished.

The previous owner, an elderly attorney named Walter Pembroke, had told me the shelves were original to the 1890 renovation.

I’d never questioned it.

Elena ran her hand along the wood.

“What exactly did you hear?”

“Three knocks.”

“From inside?”

“It sounded like it.”

She tapped one panel.

Solid.

Another.

Solid.

Then a third.

Hollow.

We looked at each other.

Elena tapped again.

Hollow.

I moved several books.

Behind them was a narrow seam I had always assumed was decorative.

It wasn’t.

The bookcase wasn’t entirely a bookcase.

Part of it was a door.

We searched for a latch.

Nothing.

Elena finally noticed a brass ornament hidden beneath the lowest shelf.

She pressed it.

A mechanism clicked.

The bookcase moved forward half an inch.

Neither of us spoke.

I pulled.

A narrow section swung outward.

Behind it was darkness.

Elena stared at me.

“Dominic.”

“I see it.”

“Perhaps we should wait until morning.”

“Why?”

“Because every intelligent decision begins with refusing to enter secret rooms at three-thirty in the morning.”

I took out my phone and switched on the flashlight.

“That’s disappointingly sensible.”

The opening revealed a narrow passage between the study and the neighboring bedroom.

Not a room.

At least not immediately.

Old plaster.

Exposed beams.

A steep set of wooden steps descended into darkness.

Dust covered everything.

Except one section of floor.

There, the dust had been disturbed.

Recently.

Elena saw it too.

“Someone has been in here.”

I crouched.

The marks weren’t footprints.

They looked more like something had been dragged.

A box, perhaps.

The passage continued downward toward the first floor.

We followed it carefully.

At the bottom was another door.

Locked.

Beside it sat a small wooden stool.

On the stool was a flashlight.

Modern.

I picked it up.

The batteries worked.

Elena folded her arms.

“That flashlight did not come with the house in 1890.”

“No.”

Someone else knew about the passage.

Someone had been using it.

The knocking suddenly seemed less mysterious.

And considerably more interesting.

I examined the door.

Old iron lock.

No obvious key.

“Tomorrow,” Elena said.

I looked at her.

“That sounded suspiciously like an order.”

“It was.”

For once, I listened.

By nine the next morning, I had slept ninety minutes.

Grace called.

Her fever had broken.

She apologized six times.

On the seventh, I interrupted.

“Stop apologizing.”

Silence.

“I need to ask you something.”

“Yes?”

“Why did you react when Mia mentioned the knocking?”

Another silence.

Longer.

“I didn’t.”

“You did.”

“Mr. Duca—”

“Grace, I’m not accusing you of anything.”

She exhaled.

“I heard it once.”

“When?”

“About a month ago.”

“Why didn’t you tell me?”

“I thought it was pipes.”

“And later?”

“I found the bookcase open.”

That got my attention.

“When?”

“Two weeks ago.”

“Was anyone inside?”

“No.”

“Did you go in?”

“No.”

“Why not?”

Her voice became quieter.

“Because Daniel told me never to.”

I stood.

“What?”

“My husband.”

“I know who Daniel was.”

“He worked in your house.”

The room seemed to change around me.

“When?”

“Before you bought it.”

I looked toward the library.

“Doing what?”

“He was a carpenter. Restoration work.”

That explained why his face had seemed familiar.

Perhaps I’d seen him in old photographs or contractor records.

Grace continued.

“When you bought the house, you kept some of the staff and hired others. Daniel recommended me for the housekeeping position.”

“Why did he tell you not to enter that passage?”

“I don’t know.”

“You never asked?”

“Of course I asked.”

“And?”

“He said the old owner kept private records down there. Daniel helped repair the hidden door, but Mr. Pembroke made him promise not to discuss it.”

Walter Pembroke.

The man who had sold me the house.

“He died six years ago,” I said.

“I know.”

“Did Daniel ever mention a locked door at the bottom of the stairs?”

Grace didn’t answer.

“Grace?”

“He had a key.”

I gripped the phone more tightly.

“Do you still have it?”

“I don’t know.”

A pause.

“Maybe.”

At noon, Grace arrived at Beacon Hill despite my telling her to remain home.

She brought a small metal box.

Mia came too, but Elena immediately claimed her for the kitchen, where they began making pancakes while Lily sat safely in a high chair banging a wooden spoon against the tray.

Grace stood in my study.

She looked smaller outside her work uniform.

Tired.

Embarrassed.

Determined.

“I found this in Daniel’s things.”

She opened the box.

Inside were photographs, receipts, old pencils, a carpenter’s folding ruler and three keys.

One was long and iron.

We went behind the bookcase.

The key fit.

The door opened.

On the other side was a small room.

Not frightening.

Not sinister.

Simply forgotten.

Shelves lined the walls.

A desk stood beneath a tiny window that had been sealed from outside.

Boxes filled the floor.

A copper heating pipe ran along one wall.

It clicked softly as warm water moved through it.

Knock.

Knock.

Knock.

Grace stared at the pipe.

I almost laughed.

“Mia’s ghost.”

“Apparently.”

But then I noticed something.

The dust.

Some boxes were covered in it.

Others weren’t.

One had been opened recently.

Grace saw it.

“That wasn’t me.”

I approached the desk.

There were papers inside.

Most belonged to Walter Pembroke.

Old property records.

Architectural plans.

Letters.

Nothing remarkable.

Then Grace lifted a folder.

Her expression changed.

“What?”

She handed it to me.

On the front, written in faded ink, were two words.

DUCA HOUSE.

I opened it.

Inside was an architectural drawing of my house.

But the date was wrong.

The drawing was from 1978.

Long before I owned the property.

A handwritten note had been clipped to the first page.

I recognized Walter Pembroke’s handwriting from the closing documents.

Dominic should be told when the time is right.

Grace looked at me.

“Did he know you before you bought the house?”

“No.”

At least, that was what I had always believed.

I turned the page.

There was a photograph.

Two men stood outside the house.

One was Walter Pembroke, forty years younger.

The other man was my father.

My father had died when I was twenty-seven.

He had never mentioned Walter Pembroke.

He had never mentioned Beacon Hill.

And he had certainly never mentioned this house.

I sat at the hidden desk staring at the photograph.

Grace remained quiet.

“What was your father’s name?” she finally asked.

“Anthony Duca.”

She looked at the picture.

“They knew each other.”

“Apparently.”

Beneath the photograph was a letter.

Not addressed to me.

Addressed to Walter.

I unfolded it.

Walter,

I appreciate what you’ve offered, but I cannot accept it. Dominic needs to build a life that belongs to him, not inherit obligations he doesn’t understand. If someday he finds his way back to the house, tell him only what he needs to know.

Anthony

That was all.

I read it again.

Then again.

Grace sat across from me.

“What does it mean?”

“I don’t know.”

But another thought had already occurred to me.

I’d bought the house eleven years earlier.

Not because of family history.

Not because of a recommendation.

I’d seen it in a private listing after three other buyers had supposedly withdrawn.

The price had been unusually reasonable for Beacon Hill.

Walter Pembroke had accepted my offer within hours.

At the time, I’d considered it good fortune.

I had built my career believing luck was simply preparation meeting opportunity.

Now I wondered whether the opportunity had been arranged.

“There’s more,” Grace said.

She was looking inside the folder.

She pulled out another envelope.

My name was written across it.

DOMINIC DUCA.

The envelope was sealed.

I opened it.

Inside was a single sheet.

Dominic,

If you’re reading this, you’ve discovered the room.

Your father asked me to keep something for you.

I agreed because I owed him more than I could repay.

But before you decide what to do with it, you should know that it does not belong only to you.

Ask Daniel Harper.

He knows where the second key leads.

Walter

Grace read the final line over my shoulder.

Neither of us spoke.

Daniel Harper had been dead for four years.

Then Grace whispered, “There was another key.”

I turned.

“What?”

“In Daniel’s things.”

She looked at the three keys in the box.

“There were four.”

“Where is it?”

“I don’t know.”

A small voice came from behind us.

“I do.”

We turned.

Mia stood in the doorway holding a plate with two pancakes.

Elena was behind her, looking apologetic.

“She escaped.”

Mia pointed at the metal box.

“The shiny key?”

Grace stared at her.

“You’ve seen it?”

Mia nodded.

“Daddy’s special key.”

Grace went pale.

“Mia, you were two when your father died.”

“I know.”

“You remember it?”

She shook her head.

“No. You showed me.”

Grace frowned.

“When?”

“Last Christmas.”

Understanding slowly crossed her face.

She sat down.

“Oh.”

“What?” I asked.

Grace looked at me.

“I gave Mia one of Daniel’s old Christmas ornaments.”

“And?”

“It wasn’t really an ornament.”

She stood abruptly.

“It was a little wooden house he made.”

Mia smiled.

“It opens.”

Grace looked toward her daughter.

“And inside…”

Mia finished the sentence.

“There’s a key.”

The second key had never been lost.

Daniel Harper had hidden it inside a tiny wooden copy of my house.

And whatever it opened had been waiting for someone to remember.
