THE MERCER TWINS PART 3 — THE HIDDEN ROOM

At 11:47 that night, my dead wife’s voice came through my phone.

“Lawson, listen carefully. The children were never supposed to become part of this.”

Then the line went dead.

I stood motionless in my office.

Two years.

For two years, I had visited Genevieve’s grave every Sunday.

For two years, I had carried the guilt of our last argument.

And now someone was using her voice to reach me.

I called the number back.

Disconnected.

Prescott entered with three armed men.

“We found Odette.”

“Where?”

“At the old greenhouse.”

“Bring her here.”

He hesitated.

“Boss, she’s unconscious. Someone attacked her.”

We found Odette lying beside the greenhouse door, her forehead bruised, her breathing shallow.

A small leather notebook had been shoved beneath her coat.

Inside were dates, medication batch numbers, and photographs of the children’s treatment records.

At the bottom of the final page, she had written:

YATES KNOWS ABOUT ROOM SEVEN.

I looked at Prescott.

“Find Dr. Yates.”

“He’s gone.”

“What do you mean, gone?”

“His car left the estate forty minutes ago. His phone is off.”

I wanted to tear the city apart.

Instead, I went to the hospital.

Jonah and Blythe had been admitted to a secure pediatric unit.

Their new doctors were reviewing their treatment history and repeating essential tests.

The specialist in charge, Dr. Miriam Chen, met me outside their room.

“Mr. Mercer, your children are critically ill,” she said. “But there are discrepancies in the records we’ve received. We need to determine exactly what treatments they were given and when.”

“Can you save them?”

“We’re doing everything medically appropriate. I won’t promise you something I can’t guarantee.”

It was the first honest answer I felt I had heard in months.

Inside the room, Evelyn sat between the children’s beds.

She was making two stuffed animals argue over who deserved the last imaginary pancake.

Blythe was smiling.

Jonah was laughing weakly.

For a moment, I forgot how to breathe.

Evelyn noticed me.

“Your son wants to tell you something.”

Jonah raised his hand.

“Daddy, Miss Evie says brave people can be scared.”

“She’s right.”

“Are you scared?”

I sat beside him.

“More than I’ve ever been.”

He touched my cheek.

“Then you can hold my hand.”

I nearly broke.

That night, after the children fell asleep, Evelyn finally told me part of her story.

She had once worked as a live-in caregiver for a private medical charity.

Genevieve had volunteered there under another name.

The two women became friends.

“Your wife was frightened before the accident,” Evelyn said.

“Of whom?”

“Someone who knew too much about the Mercer family.”

I stared at her.

“Why didn’t she tell me?”

“She tried.”

Evelyn reached into her coat and removed a brass key.

“She told me that if she disappeared, I should find the room beneath the winter garden.”

My estate had a winter garden.

A glass-roofed conservatory built by my grandfather.

But there was no room beneath it.

At least, none that I knew about.

We returned to the mansion just after midnight.

Prescott accompanied us.

Behind a wall of climbing ivy, Evelyn found an old brass lock concealed inside the stonework.

The key fit.

A section of the wall shifted inward.

Behind it was a narrow staircase.

Cold air rose from below.

We descended with flashlights.

At the bottom stood a steel door.

A small brass plate read:

ROOM SEVEN.

Prescott looked at me.

“Boss, this isn’t on the architectural plans.”

I pushed the door open.

Inside was a hidden office.

Medical files covered one wall.

There were photographs of Genevieve, Jonah, Blythe, Dr. Yates, and several people I didn’t recognize.

A large whiteboard contained dates stretching back almost three years.

And in the center of the room sat a locked cabinet marked MERCER FAMILY TRUST.

Evelyn went pale.

“Genevieve found it.”

“Found what?”

“The reason someone wanted your family destroyed.”

Prescott forced the cabinet open.

Inside were financial documents, encrypted storage drives, and a sealed envelope addressed to me.

I opened the envelope.

The first page contained a transfer authorization for forty million dollars.

The second showed a series of payments to a private medical contractor.

The third carried a signature.

Mine.

Except I had never signed it.

I turned the page.

A second signature appeared.

Crosby Vane.

My oldest enemy.

And beneath his name was a third signature that made my stomach drop.

Prescott Hale.

I slowly looked up.

Prescott stood in the doorway.

His gun was pointed at my chest.

“I’m sorry, Lawson.”

Evelyn stepped backward.

Prescott’s face was strangely calm.

“I spent fifteen years keeping you alive. But there are things about your empire you were never supposed to discover.”

“Did you hurt my children?”

His jaw tightened.

“I didn’t know how far Yates would go.”

I took one step toward him.

“Answer me.”

Prescott raised the gun.

“Don’t.”

Behind him, a familiar voice echoed from the staircase.

“Put it down, Prescott.”

Every muscle in my body froze.

A woman stepped into the light.

Dark hair.

Gray eyes.

The same small scar above her left eyebrow.

Genevieve.

My wife.

Alive.

She looked at me, tears running down her face.

“Lawson, I can explain.”

But before she could take another step, Prescott turned his weapon toward her.

And the lights went out.
