Chapter 2 - The Facade Crumbles
I barely slept that night. The brass key felt heavy in my pocket, a constant reminder of the burden my mother had carried alone for over twenty years. When morning came, I walked into our sunlit apartment in Condesa—the home I had shared with Karina for three years—and viewed every painting, every piece of designer furniture, and every soft smile through a completely different lens.
Karina was sitting at the marble kitchen island, holding a cup of artisan coffee. She looked effortlessly elegant, as she always did, wearing a cream cashmere sweater with her hair pinned back. A year ago, I would have walked over, kissed her forehead, and felt like the luckiest man in Mexico City. Today, looking at her made my blood run cold.
"Good morning, Mateo," she said, her voice dripping with soft sympathy. "How is your mother? I was so worried about her last night. I called the hospital, but they said she was in stable condition."
"She’s fighting," I said carefully, pouring myself a glass of water to keep my hands from shaking. "The doctors are running toxicology tests now."
I watched her face closely. For a fraction of a second, her micro-expression shifted—a slight tightening around her eyes, a minute freeze in her breath—before her practiced warmth returned.
"Toxicology?" she repeated, putting her cup down. "Mateo, darling, the doctors said it was an unexpected allergic reaction or a sudden decline due to her age. Why would they run toxicology tests? Are you implying something... sinister?"
"Detective Fuentes thinks it’s standard procedure when someone collapses so abruptly without prior symptoms," I lied smoothly. "Especially when poison or chemical contamination can't be ruled out."
Karina leaned forward, reaching out to touch my arm. Her hand was soft, but to me, it felt like a snake coiling around my wrist. "Mateo, you're exhausted. You're not thinking clearly. Grief and fear make us imagine monsters where there are only misfortunes. Come sit down. My father called earlier—he’s deeply concerned. He offered to fly in his private specialist from Monterrey to look at your mother."
Her father. Jorge Mendoza. The son of the man who threatened my father into an early grave. The man whose voice I had heard over Karina's speakerphone, demanding to know if "the signatures were secured."
"That won't be necessary," I replied, stepping back slightly to break her touch. "The police have locked down her medical records. No outside doctors without clearance."
A subtle chill entered the room. Karina withdrew her hand, her eyes narrowing just enough for me to see the predator beneath the socialite mask. "You're acting very strange, Mateo. Is there something you aren't telling me?"
"I could ask you the same thing, Karina," I said quietly, looking her straight in the eye. "Like why your father’s holding company suddenly filed an inquiry with the Coyoacán land registry last month."
She didn't flinch. She was too well-trained for that. "My father is a real estate developer, Mateo. He inquires about dozens of properties every week. What does that have to do with anything?"
"Nothing, I'm sure," I said, picking up my car keys. "I have to meet the police."
As I turned toward the door, her voice stopped me—no longer warm, but cold and measured. "Mateo. Don't ruin what we have over paranoid fantasies. My family has supported you. I have loved you. Remember who stands by you when things get difficult."
"I'm beginning to remember everything, Karina," I said, and walked out.
I drove straight to the precinct to meet Detective Marisol Fuentes. She was a sharp, no-nonsense woman in her late thirties with tired eyes and a mind like a steel trap. I laid out the contents of my father’s metal case across her desk: the original 1970s deed to the seventy-million-peso Coyoacán parcel, the corporate filings proving my father had sole title, and the threatening letter from Hector Mendoza.
Fuentes put on latex gloves and carefully examined the documents. "This establishes a clear motive for a land grab, Mateo. Seventy million pesos is more than enough to drive men like the Mendozas to violence. But legally proving that Jorge Mendoza poisoned your mother to secure the title through you is going to be a steep hill to climb."
"What about the poison?" I asked urgently. "Did the hospital find anything?"
Fuentes leaned back, sighing. "The preliminary lab results from your mother's blood show traces of a synthetic cardiac glycoside—a compound similar to digitalis, but harder to detect in standard screens. It mimics a heart attack or acute heart failure. If administered in small doses over several weeks, it would look like a natural, lingering illness."
A wave of intense anger flushed through me. "Karina visited my mother every Tuesday and Thursday. She always brought her homemade soup or herbal tea."
"We need physical evidence," Fuentes cautioned. "A empty vial, a syringe, or a witness. If we move too early, the Mendoza legal machine will destroy us before we even reach a judge. Jorge Mendoza practically owns half the judicial circuit in this city."
"Then what do I do?" I asked, my voice tight. "Go home and pretend I don't know my wife is trying to murder my mother?"
Fuentes looked at me with deep seriousness. "You play the grieving, confused husband. Let them think their plan is working. If they believe you are clueless, they will get sloppy. They need your signature on those power-of-attorney documents to bypass your mother’s title once she passes. As long as you don't sign, your mother is in danger—but so are you. You need to gather evidence from inside their house."

I walked out of the police station feeling like a man walking a tightrope over a canyon. I wasn't just fighting for justice for my dead father; I was fighting to keep my mother alive and to dismantle the trap my entire marriage had been built upon.
When I returned to the apartment that evening, Karina wasn't alone. Sitting on our leather sofa, drinking scotch from a crystal tumbler, was Jorge Mendoza himself.
