PART 1
When Alejandro Villalobos stepped through the grand double-height door of his mansion in Las Lomas de Chapultepec, the first sound to break the afternoon quiet was the piercing scream of his children.

Seconds later, the scene froze him in place: in the center of the vast marble hall, Lupita the nanny stood with her hands cuffed behind her back. The six-year-old twins were sobbing hysterically, clutching tightly to the pockets of her apron.
And a meter away, Paulina, his wife, stood beside two police officers. She looked flawless, her hair styled to perfection and her posture proud, as if she had just claimed victory in a country club event.
“He stole Grandma’s jewelry,” Paulina said, her voice trembling too much, an act that Alejandro thought was rehearsed. “I found the rings and necklace inside his backpack.”
Lupita, who had worked with the family for four years, looked at Alejandro with red, watery eyes, but she didn’t beg for mercy. Her only defense was a constant, choked repetition:
“I didn’t do that, Mr. Alejandro. I swear to God I didn’t. I was watching the children in the garden.”
Mateo, the more reserved and quieter of the twins, was trembling so violently that his teeth were chattering. Santiago, who had always been the more impulsive, tried to hit the officer’s belt with his small hands.
“Don’t take Lupi! She’s good, she didn’t do anything!”
Alejandro owned a network of private clinics in Mexico City. He was a man used to resolving business crises with one call to his lawyer, checkbooks, and connections. But that afternoon, inside his own home, surrounded by the scent of freshly brewed coffee and the cool drone of the central air conditioning, he felt completely powerless and trapped.
Paulina approached him, her hand brushing against his arm, and whispered coldly in his ear:
“Don’t make a scene in front of the children. This woman abused our trust and she has to pay.”
His wife’s words would have made sense if Alejandro hadn’t caught sight of Mateo’s face. In his son’s eyes, there wasn’t just fear of the police. There was a kind of deep panic, a dark resignation, as if the boy knew the real terror was only just beginning.
When the officers finally led Lupita out of the house, Santiago ran to the massive iron gate, shouting himself hoarse. Mateo, on the other hand, stood frozen in the middle of the living room, his fists clenched, staring at his mother.
Later, while Paulina was on the phone on the terrace with a friend, complaining about the “ungrateful servants,” Alejandro took the children into the kitchen. He tried to serve them some sweet pastries and chocolate milk, hoping to bring back some sense of normalcy.
“Dad,” Mateo murmured suddenly, his gaze fixed on the granite table. “My mom locks us up when she gets really angry.”
Alejandro felt the glass of milk slip from his hands, spilling onto the counter.
“Where are they locking them up, my love?”
Santiago answered before his brother, his voice breaking:
“In the dark cleaning storeroom. And Lupi always sneaks us out of there when my mom goes to her breakfasts.”
That confession tore a hole in Alejandro’s chest. Without another word, he ran up to his office, turned on his computer monitor, and accessed the recordings from the security cameras he had installed months earlier after an attempted robbery in the neighborhood.
On the screen, the recording from that same morning appeared. He saw Paulina enter her dressing room, take out the velvet case with the jewelry, walk stealthily to the laundry room, and put everything in Lupita’s worn backpack. Then, he saw her take her latest-model cell phone, dial emergency services, and start sobbing uncontrollably, like the best soap opera actress.
Alejandro watched the betrayal without blinking, feeling nauseous.
But then the system switched to another video from the previous afternoon. In the footage, Mateo accidentally spilled a glass of hibiscus tea on the Persian rug. Paulina appeared furious, grabbing the boy’s arm with brutal force and dragging him down the hallway. The door to the cleaning closet opened and slammed shut, swallowing the boy into the darkness.
The timer in the corner of the screen started ticking. It was absolutely impossible to believe what was about to happen…
