PART 1

The night Lucia found her mother under the Viaduct, she couldn't scream.

She stood there, under the rain, with a bag of sweet bread in one hand and her heart stuck in her throat.

Doña Amparo was sleeping on wet newspapers, wrapped in a dark brown blanket that wasn't hers, with her shoes full of mud and a plastic bag tied to her arm as if it was the only thing she had left in the world.

Cars, trucks, and motorcycles passed by just a few meters away, but no one turned their head.

No one wanted to look at a 72-year-old woman trembling under a bridge in the middle of Mexico City.

"Mom..." Lucia whispered, bending down in front of her. "Mom, it's me."

Doña Amparo slowly opened her eyes.

At first, she seemed not to recognize her.

Then her mouth trembled.

"Little one, don't scold me."

Lucia felt something break inside her.

Her husband, Daniel, got out of the car without saying a word. He closed the door, looked around, and left the grocery bag on the trunk.

"What happened?" he asked, his calmness was frightening.

Lucia held her mother's cold face between her hands.

"Mom, why are you here? What happened to your 8-million-peso house?"

Doña Amparo looked down.

The rain dripped from her eyelashes.

"Your brother and his wife sold it while I was in the hospital."

Lucia froze.

She didn't understand at first. Or maybe she did, but her head refused to accept something so dirty.

Doña Amparo's house was in the Del Valle neighborhood. It was an old house with a blue facade, flowerpots at the entrance, and a lemon tree her late husband had planted 25 years ago.

It wasn't a mansion, but the land was worth gold.

That's where Lucia and her younger brother, Martin, grew up. That's where Doña Amparo sewed uniforms, sold gelatin, washed strangers' clothes, and endured years of exhaustion so her children could study.

And now her own daughter was finding her under a bridge.

"Martin told me it was insurance paperwork," Doña Amparo murmured. "Fabiola took the file to the hospital. I had just come out of intensive care. My chest hurt. I couldn't see clearly."

Lucia clenched her teeth.

Three months ago, Doña Amparo had been hospitalized for a heart valve operation. Martin and his wife, Fabiola, insisted on taking care of her.

"You have work, Lu," Martin said. "Don't be paranoid. It's my mom too."

Fabiola sent pictures of soups, medicines, and flowers. "Your mom is calm." "We bathed her." "We see everything, cuz."

Everything had been a show.

Doña Amparo told her that, when she got out of the hospital, Martin told her that their house had a serious gas leak and she had to stay in a pension near La Raza for a few days.

The pension stopped paying.

Then Martin's phone stopped ringing.

Later, Fabiola blocked her.

"I thought they were having trouble," Doña Amparo said, crying softly. "I didn't want to bother them."

Lucia hugged her tightly.

Daniel didn't shout.

That scared her the most.

He took off his jacket, covered Doña Amparo, and asked: "Does she have documents?"

Doña Amparo pulled out a hidden bag from under the newspapers.

Inside were prescriptions, hospital receipts, a blurry copy of a deed, a notary's paper in Tlalpan, bank statements, and an old INAPAM ID.

Daniel took a picture of everything.

Fabiola always mocked him.

She said he was a "little government accountant" because he worked in a federal unit of financial investigation.

She never understood that Daniel reviewed cases of financial fraud, elder abuse, and money laundering.

Daniel moved 3 steps back, dialed a number, and spoke under the rain.

"I need urgent protection of evidence. Possible simulated sale of property, notarized forgery, and abuse against a hospitalized elderly person."

Lucia looked at him without breathing.

In that moment, her phone vibrated.

It was a message from Fabiola. "We know you found the woman. Don't make a scene. That house has already been sold and there's no going back."
