“If you’ve discovered the hidden room, then you’ve already seen the tunnels. This estate wasn’t originally constructed only as a mansion. The first owner used it as a transfer house.”

“Transfer house?” Marco murmured.

“For money?” Elena asked.

I shook my head.

Luca answered.

“Not for money.”

A long pause.

“For people.”

I stared at the speaker.

“During the 1920s and 30s, influential families used this estate to move witnesses, informants, defectors, and sometimes entire families without attracting attention. The tunnels connected to old service roads and a railway spur that no longer exists.”

Marco looked around the room.

“That explains the construction.”

“After the war,” Luca continued, “the network changed hands. Eventually, our grandfather acquired part of it.”

My grandfather had never explained where his earliest fortune came from.

Neither had my father.

Perhaps I had never asked because I assumed I already understood.

That was the arrogance of inherited power.

You convinced yourself history began the moment you entered the room.

Luca’s recording continued.

“But the network carried something else too. Records. Names. Agreements. Debts. Information powerful people would destroy careers to keep hidden.”

Marco’s expression sharpened.

“An archive.”

“Yes,” I said.

The house had been built to protect something.

Isabella’s note.

My children must never know what this house was built to protect.

Luca continued.

“Our father inherited access to part of the archive. Before he died, he moved it.”

I frowned.

My father had died six years earlier from a heart attack.

At least, that was what I had always believed.

“Nobody knows where he moved it,” Luca said.

“Except one person.”

The recording clicked.

Then stopped.

I stared at the screen.

“That’s all?” Marco asked.

I opened the file again.

The same ending.

“One person,” Elena whispered.

“Who?”

A soft mechanical sound came from behind us.

The grandfather clock began to chime.

Once.

Twice.

Three times.

It was not three o’clock.

Marco spun around.

All thirty clocks had started moving.

Not together.

Backward.

Their hands rotated in different directions.

Digital displays flickered.

Numbers shifted.

Then every clock stopped.

11:17.

Every one of them.

Analog.

Digital.

Even the kitchen timers.

11:17.

Elena whispered, “What happened at eleven seventeen?”

I knew.

A cold sensation moved through me.

“The boat accident.”

Marco looked at me.

“Time?”

“The Coast Guard report estimated the distress signal was sent at 11:17 p.m.”

The room lights went dark.

Elena gasped.

Emergency lighting immediately activated along the floor.

Marco reached beneath his jacket.

“Stay behind me.”

One computer screen flickered to life.

A live camera feed appeared.

The nursery.

Theo.

Miles.

Nora.

All sleeping.

Sophie sitting in the rocking chair.

Two security officers stationed outside the door.

Then the image changed.

Kitchen.

Empty.

Garage.

Empty.

Library.

Empty.

Front hall.

Empty.

The camera views began changing faster.

One room after another.

Then stopped.

My office.

Someone stood beside my desk.

A woman.

Dark hair.

Her back facing the camera.

My heart seemed to stop.

“Isabella.”

I ran.

“Adrien!” Marco shouted.

But I was already through the steel door.

Up the staircase.

Past the hidden bookcase.

Across the nursery.

Sophie looked up as I passed.

“She came back.”

I barely heard her.

I ran through the hallway.

Down the main staircase.

Across the marble foyer.

Marco and Elena followed behind me.

Security officers converged from three directions.

I reached my office.

The door stood open.

I entered.

Empty.

“Isabella?”

Nothing.

My desk lamp was glowing.

The French doors leading to the terrace were locked from the inside.

Windows closed.

Fireplace cold.

No one.

Marco arrived behind me.
