“Because three weeks ago we detected a massive illegal transfer,” he said. “Millions of pesos moved through fake foundations. It all led to a single residential address.”

I swallowed.
“Whose?”

There was a long, heavy pause.

—From your sister.

I felt like I couldn’t breathe.
—That’s impossible. Mariana is a nurse

“That’s precisely why it worked,” he said. “They used her name and address without her knowing. Someone close to her was using her network and mailbox to move the money.”

My mind started putting pieces together.
—Her husband?

—Yes —Daniel replied—. Marco.

I thought about Marco’s forced smiles. His expensive watches. Those “consulting jobs” he could never quite explain.

“I discovered it last night,” he continued. “Marco wasn’t just laundering money. He’s linked to a criminal group under federal investigation. Arms trafficking. The money was the least of it.”

I felt nauseous.
—Then why the party?

“That’s when I panicked,” she said. “Marco didn’t know the operation was happening today, but he knew the net was closing in. When you told me you were there with Emma… I realized they might use you as hostages.”

My heart started racing.
—The police…?

“I moved up the operation,” he replied. “Because I activated an emergency alert.”

I slumped back against the seat.
—You saved us.

“No,” he said softly. “I put you in danger by not telling you the truth sooner.”

That night, Mariana called me crying. Marco had been arrested in front of everyone. They found weapons hidden in the basement. Money concealed within the walls. Fake IDs.

Mariana knew nothing.
Neither did Lucía.

For weeks, Emma had nightmares. So did I. Daniel took a leave of absence from work. Federal agents interviewed us again and again. Our lives were reviewed, dissected, and documented.

But little by little, everything calmed down.

Mariana filed for divorce.
Marco accepted a plea deal with the prosecution.

And I learned something terrifying:

The people closest to you can lead double lives… and you don’t realize it until it’s almost too late.

WHEN THE SIRENS GO OFF

Life was never the same again.
Not entirely.

She became quieter.
More careful.

Mariana moved into a small apartment with Lucía. She stopped trusting people easily. So did I. Loud noises made us jump. Sirens made my heart race.
