Chapter 1 - The First Rule of the House

The heavy oak door of the service entrance clicked shut with a muffled, expensive thud, sealing off the soft Monterrey drizzle. I stood in the immaculate, sterile utility hallway of the Cárdenas mansion, clutching the strap of my canvas bag so tightly my knuckles turned white. The air here didn’t smell like the reheated coffee and eucalyptus vapor of our tiny apartment in Independencia; it smelled faintly of lemon oil, beeswax, and absolute, crushing isolation.
Mrs. Herrera stood before me, her posture as rigid as the iron-pressed creases of her charcoal skirt. For ten minutes, she had subjected me to a tour that felt less like an orientation and more like an inspection of a military installation. Every surface in the mansion gleamed with a cold, intimidating perfection. The floors were black granite polished to a mirror finish; the windows looked out over gray balconies that melted into the morning fog creeping down from the Chipinque mountains.
"Rule number one," Mrs. Herrera said, her voice dropping into a dry, authoritative register that brooked no argument. She pointed a manicured finger toward a set of heavy double doors at the far end of the grand landing. "Mr. Cárdenas’s study. You do not enter unless summoned. You do not touch his desk, you do not move his books, and you certainly do not look at his private papers."
"I understand," I replied quietly, keeping my eyes respectfully lowered, exactly as Grandma Carmen had advised. Don’t smile too much at first.
"Rule number two," Mrs. Herrera continued, turning down a darker, narrower corridor on the second floor. She stopped dead in front of a heavy, brass-fitted door that lacked any visible keyhole. A cold draft seemed to emanate from beneath its threshold. "This room remains locked. Always. Under no circumstances are you to attempt to open it, clean it, or even linger near it. If Mr. Cárdenas finds so much as a speck of dust on that handle, you will be out on the street before you can blink."
I swallowed hard, feeling an uninvited chill crawl up the back of my neck. "Why is it locked?"
Mrs. Herrera’s sharp gaze flashed, her thin lips pressing into a hard line. "Because Mr. Cárdenas ordered it. Some doors in this house are sealed for a reason, Elena. Leave them that way."
She dismissed me with a wave of her hand, assigning me a stack of fresh linens and a checklist of minor chores on the ground floor. For the next three hours, I moved through the sprawling kitchen and formal dining room like a ghost, scrubbing surfaces that were already spotless, dusting mahogany tables that had no dust, and listening to the low, melancholic ticking of a grandfather clock in the hall.
My mind kept drifting back to Grandma Carmen. Back in Independencia, she would right now be sitting by the small living room window, her swollen fingers gripping her rosary beads while the oxygen machine pumped a steady, rhythmic breath into the quiet apartment. She needed a new tank by Friday. The prescription refill cost more than half of my weekly advance. If I messed this up—if I let the cold, unforgiving aura of this mansion break my resolve—everything we had built would collapse.
Around noon, the heavy front doors swung open.
I was wiping down the baseboards near the grand staircase when I heard the sharp, decisive click of leather shoes hitting the granite floor.
Rodrigo Cárdenas.
He didn't look down. He walked with the heavy, unyielding momentum of a man carrying the weight of an industrial empire on his broad shoulders. His custom-tailored charcoal suit was unbuttoned, his silk tie loosened slightly at the throat, and his dark hair fell in damp waves across his forehead from the morning rain. But it was his face that caught me off guard. It wasn't just stern; it was hollow. He looked like a man who had not slept a deep, dreamless sleep in years—a walking monument to grief wrapped in expensive fabric.

He paused for a fraction of a second near the bottom of the stairs. His dark eyes flicked downward, briefly catching mine where I knelt by the baseboard. There was no warmth in his gaze, only a heavy, exhausting indifference.
Then, without a word, he turned and strode up the stairs toward his forbidden study, leaving a trail of cold air in his wake.
