THE BILLIONAIRE'S DAUGHTER WAS CALLED A MONSTER—UNTIL HER NEW NANNY DISCOVERED WHAT WAS HIDDEN BEHIND THE BLUE DOOR

I was frightened.

Of course I was.

But fear had become easier to manage once I understood what I was fighting for.

At the service elevator, I remembered the injured woman I'd passed on my first morning.

Four bloody scratches.

A soaked blouse.

A warning.

Don't go up there.

I turned toward Gabriel, who had accompanied me.

"Can you find the nanny who left yesterday?"

He glanced at me.

"What do you know about her?"

"Almost nothing."

"Why?"

"Because she was scared enough to warn a complete stranger."

Gabriel considered that.

"Her name is Evelyn Park. She was hired through the same staffing agency."

"Can we contact her?"

"I can ask whether she'd be willing to speak with us."

I nodded.

"Please."

Upstairs, Matteo was waiting beside the living room windows.

He looked as though he hadn't slept.

His shirt collar was open, and dark shadows lay beneath his eyes.

Leah sat on the rug several feet away, lining up toy animals.

When she saw me, she froze.

Then she ran across the room.

"Maya!"

I crouched.

She stopped just short of my arms.

For one moment, she looked uncertain.

Then she leaned forward.

I hugged her gently.

"Good morning, sweetheart."

Her little shoulders relaxed.

"You came."

"I did."

She stepped back and examined me as though checking for hidden injuries.

"Train hurt?"

I touched my shoulder.

"A little."

Her eyes filled.

"Sorry."

The word nearly broke me.

I shook my head gently.

"Thank you for saying that. We can practice safer ways to show big feelings."

She nodded.

Then she picked up one of the toy animals and handed it to me.

It was a small wooden elephant.

"Elephant brave," she announced.

I smiled.

"Is he?"

She nodded seriously.

"Scared. Still brave."

I looked up at Matteo.

He was watching us.

And for the first time, I saw something softer than guilt in his expression.

Hope.

Later that morning, Dr. Price called to discuss the next steps following Leah's evaluation.

She recommended working with a qualified child-trauma clinician, maintaining consistent routines, and letting Leah regain a sense of control over ordinary choices.

Matteo listened carefully.

He asked questions.

He took notes.

He didn't interrupt.

When the call ended, he turned toward me.

"I used to think being a good father meant providing everything she could ever need."

I glanced at Leah.

"She needs you, too."

His eyes lowered.

"I know that now."

Around noon, Gabriel received a return call from Evelyn Park.

She agreed to meet us in a quiet conference room downstairs, with a lawyer present.

I was surprised to recognize how young she looked.

Maybe twenty-four.

Her cheek carried four thin red scratches beneath a protective dressing.

She kept twisting the strap of her purse.

When she saw me, her face changed.

"You're the woman I warned."

I nodded.

"I'm Maya."

She looked toward Matteo.

Then she stood abruptly.

"I shouldn't be here."

Matteo raised both hands.

"You can leave whenever you want."

She looked at the door.

I moved away from it.

"Nobody's stopping you."

For a moment, I thought she would run.

Instead, she sat down again.

"I'm sorry," she whispered.

Matteo frowned.

"For what?"

"For what I did to your daughter."

The room fell silent.

Evelyn looked at me.

"She wasn't always violent."

I pulled out a chair.

"Tell us what happened."

Her voice shook.

"When I started, Leah was quiet. She didn't want me to touch her, but she followed me around the apartment. She liked when I read to her."

She wiped her eyes.

"Then Celeste started giving me instructions."

"What kind?" Matteo asked.

"She told me to remove toys if Leah refused to follow directions. She said that when Leah cried, I shouldn't comfort her because I would reinforce the behavior."

Matteo closed his eyes.

Evelyn continued.

"Then she introduced the blue room."

Her hands began trembling.

"Celeste said Leah needed to spend short periods alone until she could regulate herself."

"Did you know the door locked?" I asked.

Evelyn nodded.

"I did."

She began crying.

"I should have refused. I should have reported it."

I stayed silent.

She deserved room to tell the truth.

"Yesterday, Celeste ordered me to take Leah inside after lunch. Leah started screaming before we reached the hallway."

"What happened next?"

"She grabbed my sleeve. I tried to lift her, and she scratched my face."

Evelyn touched her cheek.

"I dropped her."

Matteo sat forward.

"Did she fall?"

"Onto the carpet. She wasn't badly hurt, but she cried. Then Celeste told me to leave."

"Where was Leah?" I asked.

"In the hallway."

"Did Celeste lock her inside?"

"I don't know."

Evelyn swallowed.

"I couldn't stay. I went to the bathroom, washed my face, and told the agency I was quitting."

She looked at Matteo.

"I'm sorry."

His jaw worked.

Finally, he spoke.

"Did you ever tell anyone what was happening?"

"I tried."

"Who?"

"Marianne Duca."

Matteo went still.

Evelyn opened her purse.

She removed her phone.

"I sent her a message three weeks ago. I told her the room was frightening Leah and that Celeste wasn't listening."

She turned the screen toward us.

The response appeared beneath her message.

Marianne Duca: Follow the approved program. You are not qualified to challenge the treatment team.

Matteo looked away.

Evelyn scrolled.

"Then she called me."

"What did she say?"

"That if I quit, the agency would consider me unreliable. She said she'd make sure I never worked for another wealthy family in New York."

I felt sick.

Evelyn wiped her face.

"I have student loans. My mother helps pay my rent. I was scared."

I understood more than she knew.

Matteo looked at her.

"Would you be willing to give that information to the investigators?"

She hesitated.

Then nodded.

"Yes."

Gabriel spoke for the first time.

"Did you sign an incident report about Leah?"

Evelyn's expression changed.

"No."

Matteo frowned.

"Your name appears on one."

She stared at him.

"What?"

He opened a folder.

He showed her a document describing Leah as dangerously aggressive.

At the bottom was Evelyn's name.

And a signature.

She stared at it.

"That's not mine."

The room became completely silent.

Evelyn shook her head.

"I never signed that."

Gabriel photographed the page.

Then Evelyn said something that changed the entire direction of our investigation.

"There's another thing."

We all looked at her.

"Celeste had a red notebook."

Matteo leaned forward.

"What notebook?"

"She kept it in the cabinet beside the blue room. Every time Leah had an outburst, she wrote down what happened."

"That sounds like a treatment log," Gabriel said.

Evelyn shook her head.

"No."

She looked directly at me.

"She wrote down what she did before Leah became upset."

My pulse quickened.

"What do you mean?"

Evelyn swallowed.

"Sometimes she took away Leah's favorite blanket. Sometimes she made her watch videos of her mother. Once she played a recording of Matteo saying goodbye."

Matteo stopped breathing.

Evelyn's eyes filled again.

"Then she waited for Leah to cry."

I felt cold.

She whispered the sentence I would never forget.

"The tantrums weren't what Celeste was studying."

Matteo looked at her.

"Then what was she studying?"

Evelyn lowered her voice.
