Three Days After My Divorce, My Ex-Husband’s Mistress Mocked Me for Finding a Rich Old Man—Then He Stood Up and Called Me His Daughter

My father insisted that Camila come with us.

She resisted at first, saying she had already caused enough trouble and didn't want to be dragged into another family confrontation.

But when she tried to walk toward the street alone, a black sedan rolled slowly past the hotel entrance.

She stopped.

So did I.

The driver wore sunglasses. The windows were dark enough to conceal the passenger compartment, but I recognized the vehicle from the photograph of Beatriz at the airport.

Camila gripped my sleeve.

“That's him.””

“The man in the charcoal suit?””

She nodded.

“He followed me the night I found the letter. I thought I lost him.””

My father signaled to our driver.

“Get everyone into the car.””

We left the hotel through the side entrance and moved quickly toward the waiting vehicles. Security followed in a second car.

The black sedan remained at the curb.

Nobody approached us.

But as our car pulled away, I saw the rear window lower slightly.

A hand appeared.

Holding a photograph.

The same photograph of the original construction site.

The window rose again.

I watched the sedan disappear into traffic.

Camila sat beside me, pale and silent.

My father was in the front passenger seat, speaking quietly with security. He had not answered my question about the message.

I waited until the driver turned onto a quieter road.

“Dad, who ordered Isabel's disappearance?””

He turned around.

“I don't know.””

“Someone claims the person is sitting in your office.””

“Someone is trying to make us distrust everyone around us.””

“That doesn't answer the question.””

He looked at Camila.

“Your mother disappeared twenty years ago. I have no proof that she was murdered, abducted, or forced to leave Mexico. We cannot treat an anonymous message as evidence.””

Camila's voice was small.

“She wouldn't have abandoned me.””

My father softened.

“I understand.””

“No, you don't.””

She wiped her face with the sleeve of her jacket.

“My grandmother raised me. She told me my mother had gone away because she couldn't handle being a parent. Whenever I asked for photographs, she said there were none. Whenever I asked about my father, she said he had never wanted to know me.””

She looked down at the envelope.

“Then, after my grandmother died, I found letters hidden behind a drawer. My mother had written to her every few months. She kept asking whether it was safe to come home.””

My chest tightened.

“Did your grandmother answer?””

“Sometimes. The last letter was dated when I was six. My mother wrote that she had found a way to prove what happened to the money, but she couldn't risk contacting me until she was certain I was safe.””

Camila's voice broke.

“After that, there was nothing.””

I looked at her.

For the first time, I saw something beyond the woman who had taken my husband.

I saw a child who had grown up believing her mother had abandoned her, then discovered that someone might have deliberately erased her mother's life.

It didn't excuse what she had done to me.

But it made her pain real.

“Why did you become involved with Alejandro?”” I asked.

She stared out the window.

“I met him at a business reception. He was charming, and he listened when I talked about my mother's disappearance. I told myself he might help me find the old records.””

“And then you fell in love with him?””

She closed her eyes.

“I thought I did.””

“That isn't the same as answering.””

“No,” she whispered.

“It isn't.””

I waited.

She turned toward me.

“I wanted to win. I wanted to prove I could get close enough to the De la Vegas to find out what they had hidden. Then Alejandro made me feel important, and I let myself believe that what we had was more than an arrangement.””

“Did you know he was married?””

“Yes.””

The honesty hurt more than another excuse would have.

“And you continued anyway.””

“Yes.””

She looked down.

“I knew about you. I knew he came home to you. I knew you weren't some distant wife who had stopped caring. I saw your photographs on his desk.””

I remembered the wedding picture.

“You knew he kept our photograph?””

She nodded.

“He never threw it away. He said it reminded him of the man he had wanted to become.””

I stared at her.

That was a sentence I had never heard from Alejandro.

“What happened to that man?”” I asked.

Camila looked away.

“I don't know.””

Neither did I.

We reached my father's residence twenty minutes later. Security escorted us inside, and Elena was already waiting in the study with a fresh report.

She looked at Camila.

“Ms. Serrano, we need to verify your identity and document everything you have provided. You'll be treated as a witness unless the evidence establishes otherwise.””

Camila nodded.

“I understand.””

My father placed the anonymous messages on the desk.

“Have we identified the sender?””

“Not yet,” Elena replied.

“The number appears to have been routed through a service that masks the original source.””

“And Rafael?””

“We still haven't located him. His assistant confirmed that he left his office before noon, but no one can verify where he went afterward.””

My father looked toward me.

“Valeria, you and Camila should stay here until we know who is following her.””

I didn't argue.

Elena began photographing the letter and recording Camila's statement. She asked about the bracelet, the consulting contract, the financing file, and the man in the charcoal suit.

Camila answered each question.

When Elena asked whether she had any evidence that the consulting payments were connected to the old missing funds, Camila reached into her bag.

“I have this.””

She placed a small flash drive on the desk.

“I copied the files from a computer in Alejandro's office. I shouldn't have done it without authorization, but I found a folder containing archived documents. Some were from the original project.””

Elena did not touch the drive.

“Did you access the files using your own credentials?””

“No.””

“Whose credentials did you use?””

Camila looked at me.

Then at my father.

“Rafael Ortega's.””

The room fell silent.

My father leaned forward.

“How did you obtain his credentials?””

“I found them in a document stored on Alejandro's office computer. I don't know whether he gave them to someone or whether they were saved there by mistake.””

“Did you download anything else?””

“Only the files related to Isabel Serrano and Varela Holdings.””

Elena put on gloves and placed the drive in an evidence bag.

“We'll create a forensic copy and preserve the original.””

Camila nodded.

“There's something else you need to know.””

She looked at me.

“The man in the charcoal suit isn't Gabriel Varela. His name is Nicolás Varela. He's Gabriel's son.””

My father stiffened.

“Gabriel had a son?””

“Yes. Nicolás took over several of his father's companies after he died. He's been managing Varela Holdings for years.””

“Then why was Beatriz meeting him at the airport?”” I asked.

Camila hesitated.

“Because they have a business arrangement.””

“What kind?””

“I don't know exactly. But I've seen documents showing payments from Varela Holdings to companies associated with Beatriz. Some of the payments continued long after Gabriel's death.””

My father looked at Elena.

“Add those entities to the review.””

She nodded.

Camila reached into her bag again and removed a folded page.

“This was in the archive.””

It was a copy of a ledger, yellowed around the edges. Several entries had been marked in red ink. Each entry listed a payment, a company, and a set of initials.

I scanned the page.

One entry was dated twenty years earlier.

Another was dated six months ago.

The same intermediary company appeared in both.

The newest entry showed a payment from Varela Holdings to Serrano Strategic Consulting.

Beside it were the initials C.S.

I looked at Camila.

“Did you receive this money?””

She nodded.

“Some of it. I thought it was payment for research.””

“Did you know the source?””

“No. I didn't have access to the original accounts.””

“Did you spend it?””

“Some. I paid for travel and document retrieval. The rest is still in the company's account.””

My father looked at Elena.

“Can the funds be traced?””

“Yes, if the account records are preserved.””

I turned back to Camila.

“Why didn't you tell me this earlier?””

“Because I was afraid you'd assume I had planned the entire affair to steal from your family.””

“Had you?””

“No.””

She swallowed.

“But I did use Alejandro. I told myself the information mattered more than the damage I caused. I was wrong.””

For a moment, I didn't know what to say.

Then I asked the question that had been bothering me since the hotel.

“What happened to your mother?””

Camila looked at the old ledger.

“I don't know. But I think the records can tell us where she went.””

Elena connected a secure workstation to the forensic process and began examining the copied files.

A few minutes later, she called my father over.

“Mr. Mendoza, there's a document here that requires your attention.””

He stood beside her.

I followed.

The file was a scanned letter dated twenty years earlier. Its metadata showed that it had been stored in an archive associated with the original development project.

The recipient was Arturo Mendoza.

The sender was Isabel Serrano.

My father read the first paragraph.

Then he sat down.

“What is it?”” I asked.

He didn't answer.

I took the screen in.

The letter described a plan to transfer money out of the project accounts. Isabel wrote that she had discovered evidence that Beatriz and Gabriel Varela were preparing to move the remaining funds into a series of shell companies.

But the final paragraph changed everything.

I have learned that Ricardo de la Vega did not authorize the original transfers. He tried to stop them. When he discovered what Beatriz had done, he threatened to report her. Two days later, he was dead.

I stared at the screen.

Ricardo de la Vega had died in a car accident, according to the public account of his death.

I looked at my father.

“Did you know this?””

He shook his head slowly.

“No.””

The letter continued.

Arturo, if anything happens to me, please protect my daughter. She is the only innocent person left in this family, and Beatriz has made it clear that she will do whatever is necessary to keep the truth from coming out.

Camila covered her mouth.

“My mother knew.””

Elena scrolled to the bottom.

There was a final line, written in a different hand.

The child must never learn that her father is alive.

Camila went completely still.

“What does that mean?””

My father leaned closer to the screen.

The letter's original signature was visible at the bottom.

Isabel Serrano.

Below it, someone had added a note in black ink.

*Father's identity confirmed. Biological father: Gabriel Varela.*

Camila took a step backward.

“No.””

Nobody spoke.

She shook her head, repeating the word as though she could make the document disappear.

“No. My mother told my grandmother that my father had died before I was born.””

I looked at the page.

Gabriel Varela had apparently been alive when Camila was conceived. He had been involved in the original financial scandal. His son Nicolás now controlled Varela Holdings. And someone had spent years hiding the identity of Camila's father.

My father closed the file.

“We need to verify the document's authenticity before drawing conclusions.””

Camila sank into a chair.

“Then all these years, he was alive?””

“Possibly,” my father said gently.

“We don't yet know when he died or whether the record is accurate.””

She stared at him.

“You knew him.””

“Yes.””

“And you never told me.””

“I didn't know you existed.””

The room went quiet again.

I looked at the old ledger, the letters, and the transfer records. Every answer seemed to open another question.

Then Elena spoke.

“There's one more file.””

She opened a scanned property document.

It showed the ownership history of a small residential property outside Mexico City, purchased under a different name twenty years earlier.

The listed occupant was Isabel Serrano.

The most recent utility payment had been made three weeks ago.

I leaned toward the screen.

“She's alive.””

Elena nodded cautiously.

“The records suggest someone has been maintaining the property. They don't prove that Isabel currently lives there.””

Camila rose so quickly that her chair tipped backward.

“Where is it?””

My father stood.

“We'll send a team to verify the address.””

“I want to go.””

“Camila—”

“She may be my mother. I have spent my entire life wondering whether she was alive. I'm not waiting in another room while someone else decides what I deserve to know.””

I looked at her.

I understood that feeling better than I wanted to.

My father considered her request.

“Security will accompany us. No one goes alone.””

He turned to Elena.

“Contact the authorities and arrange a welfare check. We are not entering the property without the proper authorization.””

Elena began making calls.

Camila stood beside the table, trembling with anticipation and fear.

I took her hand.

She looked at me in surprise.

“Don't mistake this for forgiveness,” I said quietly.

“I haven't forgiven what you did to me.””

“I know.””

“But if your mother is alive, you deserve the chance to find out.””

Her eyes filled.

“Thank you.””

I released her hand.

Outside, the sky had darkened, and rain began to tap against the study windows.

Somewhere beyond the city, a woman who had been missing for twenty years might still be alive.

And if the documents were authentic, she might be the only person who could explain what had happened to Ricardo de la Vega, why the money had disappeared, and who had spent two decades protecting the truth.

My father picked up his coat.

“We leave in ten minutes.””

Camila stared at the address on the screen.

Then her phone rang.

An unknown number.

She answered before anyone could stop her.

“Hello?””

A woman's voice came through the speaker.

It was faint, trembling, and unmistakably frightened.

“Camila?””

Camila stopped breathing.

“Mom?””
