THE UNFINISHED VOWS

The black sedan tore through the streets of Madrid, the city lights blurring outside the window.

I sat in the back seat, my fingers tracing the tiny engraving on the diamond bracelet. Calle de los Olivos, 14.

My mind was racing faster than the car. David was locked in a bank vault, Julian was in police custody, and Sofía’s cruel betrayal had been exposed. The people who had tried to destroy Mateo were finally caught.

But the fear hadn't left my chest.

If David was the true mastermind, why did Mateo hide the final piece of evidence at this specific address?

Twenty minutes later, the car pulled into a quiet, tree-lined suburban street. The houses here were small, unassuming, and covered in climbing ivy. It was a world away from the lavish Montenegro estates.

The driver parked in front of number 14.

"Wait here," I told him, stepping out of the car.

The night air was cool. I walked up the cracked concrete path, my ruined wedding dress dragging leaves and dirt behind me. The house was dark. There were no lights on inside, but the front door was painted a bright, cheerful yellow.

I knocked.

Silence.

I knocked harder, my knuckles aching.

"Please," I whispered. "Someone be here."

I heard a soft shuffle behind the door. The deadbolt clicked, and the door opened just an inch, held back by a brass security chain.

An older woman with silver hair and kind, tired eyes peered out at me. She looked at my white dress, my messy hair, and the desperate expression on my face.

"Can I help you?" she asked softly.

"My name is Lucía," I said, holding up the diamond bracelet. "Mateo Montenegro sent me."

The woman's eyes widened. She quickly undid the chain and pulled the door wide open.

"Come in, child. Quickly."

I stepped into a small, warm living room that smelled of cinnamon and old books. The walls were covered in framed photographs. But they weren't pictures of landscapes or art.

They were pictures of a little boy.

A little boy with Mateo’s dark eyes and messy brown hair.

"You're Leo's nanny," I breathed, looking at a photo of the woman pushing a swing.

"I am Rosa," the woman smiled gently, closing the door behind me. "I was Leo’s foster mother before Sofía took him. Mateo pays me to look after him when Sofía is... unavailable. Which is most of the time."

"Is Leo here?" I asked, looking toward the hallway.

"No, he is on a school trip to Toledo until tomorrow," Rosa said. She looked at my dress again, her expression turning sorrowful. "Mateo told me you were getting married today. I am so terribly sorry."

"How much do you know?" I asked.

"I know Mateo was terrified," Rosa walked over to a small wooden desk in the corner. "He came here two nights ago, in the middle of the rain. He said he found something in the company archives. Something David the lawyer had hidden. He said if anything happened to him, he would leave a clue for you to find this house."

She opened the desk drawer and pulled out a thick, sealed manila envelope.

She handed it to me.

"He said this would destroy the Montenegro company. But it would keep Leo safe forever."

I took the envelope. It was heavy.

"Thank you, Rosa," I whispered.

"Mateo loves you very much, Lucía," she said, touching my arm. "He wanted a family with you. A real one. With Leo."

I smiled through my tears. "We’re going to have it."

I left the house and got back into the sedan.

"Take me back to the hospital," I told the driver.

As we sped back toward the city center, I tore open the envelope.

Inside were bank records. Decades old. Transfers showing millions of euros being moved from the Montenegro corporate accounts into a shell company owned by David Vargas. It was proof of massive, systemic fraud. It was enough to put the lawyer away for the rest of his life.

But there was something else at the bottom of the envelope.

A small, rectangular piece of paper.

I pulled it out.

It was an old, faded airplane ticket stub.

The name on the passenger list was Elena Montenegro. Mateo’s mother.

The destination was Buenos Aires, Argentina. The date was exactly ten years ago. The day she supposedly died in a tragic boating accident off the coast of Ibiza.

I stared at the ticket, my blood running cold.

Attached to the ticket was a handwritten note from Mateo.

Lucía, my mother didn't die ten years ago. She faked her death to escape my father's abuse. David helped her do it. In exchange, she let him steal from the company. But she came back. She is in Madrid. And she is the one who cut my brakes.

My phone rang violently in my hand, making me jump.

It was Álvaro.

I answered it, my hands shaking uncontrollably. "Álvaro, I found the evidence. But you have to listen to me—"

"Lucía," Álvaro interrupted, his voice trembling with sheer terror. "You need to get back here. Right now."

"What’s wrong? Is Mateo okay?"

"He's awake," Álvaro whispered. "He woke up. But he won't let the doctors touch him. He won't let me near him."
