PART 1

—Did you really think I wouldn’t find out that you gave my Mercedes to your lover?

Mariana Rivas didn’t scream when she said those words. That was what frightened Diego the most: the calm with which his wife looked at him from the entrance of the house, her suitcase still beside her and her face pale from the exhaustion of the trip. She had come from Monterrey after four days of meetings, delayed flights, and forced smiles for clients. She just wanted to kick off her heels, shower, and sleep. But when she opened the garage door of her house in Mexico City, she found the space empty.

The blue Mercedes that he had bought with years of work, saved bonuses and sleepless nights, was gone.

At first she thought Diego had taken it to be washed. Then she thought maybe he’d moved it because of an emergency. But something in the silence of the house tightened her chest. Everything was too tidy, as if someone had hastily cleaned away any trace of guilt.

He wrote to her.

“Where is my car?”

Diego left the message on read.

Mariana called once. Twice. Three times. Nothing.

Then a patrol car stopped in front of the house.

An officer got out with a notebook and asked:

—Are you Mariana Rivas?

She felt her legs go weak.

—Yes… what happened?

—A Mercedes vehicle registered in her name was involved in an accident on Revolución Avenue. The driver identified herself as Camila Duarte. She said her husband lent her the car.

For a few seconds Mariana didn’t understand anything. The words seemed disconnected: accident, driver, husband, Camila. Then they clicked together and hit her like an invisible slap.

“I didn’t authorize anyone to drive it,” she said, in a cold voice that even she didn’t recognize. “That car is mine. It’s only registered in my name. I was out of town.”

The officer nodded.

—Then you can file a report for unauthorized use of the vehicle.

Mariana looked at the empty garage. She remembered the day she bought that car. Diego had feigned pride, but ever since then, every time she drove it, he would throw out comments disguised as jokes.

“You look like a rich lady now.”

“It’s great that someone in this house can afford luxuries.”

“Just don’t forget that we’re still married.”

She had learned to lower her voice when she spoke of her promotions. To not celebrate her achievements so much. To pay more of the mortgage without saying anything so that he wouldn’t feel left out.

But that night something broke.

“I want to report it,” he said. “As stolen.”

The officer looked up.

Are you safe?

-Completely.

When Diego called, Mariana was already sitting in the bedroom, looking at her nightstand. There was an expensive watch he claimed to have bought “on sale,” a new shirt that wasn’t her style, and an elegant perfume she’d never seen before.

“Mariana, please don’t make a scene,” he said as soon as she answered. “I’ll explain when I get there.”

-Where are you?

Silence.

—At the hospital. Camila had a minor injury. Nothing serious.

Camila.

The familiarity with which he pronounced that name made her stomach churn.

—What a relief to know your lover is okay—Mariana replied.

—She’s not my lover. It’s complicated.

—No. It’s complicated to pay for a car for 6 years only for your husband to give it to another woman while you’re at work.

Diego breathed with suppressed anger.

—Don’t exaggerate. I only lent it to him.

Mariana let out a dry laugh.

“Don’t come back to this house tonight. If you set foot in the doorway, I’ll call the police.”

He hung up.

Then she called Lucia, her best friend.

—Diego gave my car to his lover… and she crashed it.

Lucia remained silent for 3 seconds.

—I’m on my way. And I’m taking my laptop. You don’t cry about this first, Mariana. You investigate first.

That morning, on the kitchen table, they found receipts from hotels, jewelry stores, restaurants, and a bedroom set delivered to an apartment in the Del Valle neighborhood. The recipient’s name: Camila Duarte.

Then a hidden folder appeared on Diego’s tablet: messages from 14 months ago, photos of Camila inside the Mercedes, emails with lawyers, and a sheet called “Options,” where Diego calculated how much he could take from Mariana if he got a divorce.

Mariana stopped breathing when she read a note written by him:

“Create emotional distance before moving money.”

Lucia looked at her in horror.

—I wasn’t confused. I was setting a trap for you.

At 2 a.m., Mariana printed everything. And before dawn, she received a message from Camila:

“Sorry about the car. Diego told me I could use it. I didn’t think you’d make such a fuss.”
