Chapter 2 - The Silent Partner
Detective Fuentes met me at a quiet 24-hour diner near the district precinct. The artificial fluorescent lighting did nothing to soften the exhaustion on her face, but her eyes locked onto the contents of my father’s steel box with sharp, professional focus.
As I laid out the original Coyoacán land deeds, the legal correspondence, and the hospital records showing the subtle, elevated levels of digitalis found in my mother’s blood work, Fuentes took a long sip of black coffee.
"Digitalis poisoning causes symptoms that mimic late-stage heart failure," Fuentes said quietly, studying a land transfer document signed in 1978. "In an elderly woman with a history of hypertension, a doctor who isn't looking for foul play would simply sign the death certificate. It’s quiet. It’s calculated."
"And Karina has been controlling my mother's daily medication regimen for the last six months," I said, the words tasting like ash in my mouth. "She insisted on taking over her care, claiming she wanted to lighten my burden while I was working late."
"Your wife didn't just walk into your life by accident, Mateo," Fuentes noted, pulling out a notepad. "Jorge Mendoza didn't just wake up one day and remember a forty-year-old land dispute. This was a long game."
That night, I returned to the home I shared with Karina. The house was quiet. She was sitting in the living room, a half-empty glass of wine in her hand, looking at her phone. When the front door closed, she looked up, her expression a masterclass in performative concern.
"Mateo, my love," she whispered, stepping toward me. "How is your mother? I tried to come back to the hospital, but the doctors said she needed total rest."
Looking at her—the woman I had married two years ago in a small, beautiful ceremony in San Ángel—I felt a profound, chilling detachment. I saw the fine details now: the subtle, calculated way her father, Jorge Mendoza, had arranged our "random" meeting at an architectural gala; the way she had subtly steered me away from managing my mother's affairs; the gentle pressure she exerted every time financial planning came up.
"She’s stable," I replied, keeping my voice carefully devoid of emotion. "The doctors are running toxicology tests to find out why her heart gave out so suddenly."
I watched her face closely. For a fraction of a second, her posture stiffened. Her eyes flicked away from mine, a micro-expression of panicked calculation before her mask of grief snapped back into place.
"Toxicology?" she asked, her voice tight. "Why would they do that?"
"Routine protocol," I lied smoothly. "They suspect a faulty batch of her prescription meds. They’re impounding all her pill bottles from the house to run lab analyses."

Karina’s breath caught slightly. She forced a sympathetic smile, but her knuckles turned white as she squeezed her glass. "That’s... good, Mateo. We need to know what happened."
She thought she was playing me. But for the first time in two years, the board was reversed.
