PART 1

If my daughters don’t eat in the next 48 hours, they will die of malnutrition, and I will be the father who let them die. Eduardo Mendoza’s words echoed throughout the mansion in Lomas de Chapultepec like an inescapable sentence. It was 2:30 p.m. on Tuesday. Sofía and Isabela, his 18-month-old twins, had gone six whole days without a bite to eat.

At 34, Eduardo was a successful real estate businessman with a fortune of over 180 million pesos, but at that moment, all his money was worthless. He seemed to have aged 10 years in just 3 months. His hair was disheveled, and his eyes reflected utter despair. The girls had been born after a perfect pregnancy, but his wife Mariana died from complications a week after giving birth. For 15 months, the babies grew healthy, until, exactly on the anniversary of Mariana’s death, they stopped eating.

Eduardo had spent over two million pesos on the best specialists in Mexico and Latin America. They all reached the same conclusion: the girls were physically healthy. There were no allergies or digestive problems. Desperate, Eduardo hired Dr. Valeria Montenegro, the most prestigious and exclusive pediatric nutritionist in Mexico City, who charged 5,000 pesos per consultation. The doctor had issued a cruel ultimatum: if they didn’t eat within 48 hours, the girls would be hospitalized, isolated from their father, and fed through a gastric tube.

That same morning, Mercedes, the 52-year-old housekeeper, brought Citlali, a 26-year-old Zapotec woman recently arrived from the mountains of Oaxaca. Citlali had no medical degrees, but she carried a satchel full of herbs, pure cacao, and the wisdom of four generations. Upon entering the immense marble dining room, Citlali didn’t see a single clinical problem in the sunken faces of the twins; she saw two small souls broken by the absence of their mother.

Ignoring the house protocols, Citlali went to the kitchen. She prepared a traditional cacao atole with honey and cinnamon, using a wooden whisk while singing an ancient Zapotec melody. The sweet aroma filled the mansion. When she brought the clay bowl closer to the girls, the first miracle in six days occurred: Sofía opened her eyes wide, took the spoon, and sipped. Isabela imitated her two seconds later. Eduardo fell to his knees, weeping with relief.

But the peace lasted exactly 1 minute.

The dining room doors burst open. Dr. Valeria Montenegro stormed in, furious. Without a word, she slammed her hand down on the clay bowl, smashing it on the floor. “You’re poisoning my patients, you ignorant servant!” Valeria shouted. Then she glared coldly at Eduardo: “You’re an incompetent father. I’m calling the authorities right now to have you removed from my care.”

While Eduardo stood frozen with terror, Citlali, crouching down to gather the pieces of mud, noticed something shiny in the doctor’s half-open briefcase. No one in that mansion could have imagined the chilling truth that was about to be revealed…

PART 2

Valeria’s words rang out like gunshots. Absolute panic gripped Eduardo. The mere mention of the government taking his twin daughters away left him completely vulnerable and devastated. Accustomed to managing corporations with thousands of employees, he was now just one terrified man who felt he was failing his late wife.

“Don’t call the authorities, Valeria, I beg you!” Eduardo pleaded, stepping between the doctor and her cell phone. “I’ll do whatever you ask. I’ll pay whatever it takes.”

Dr. Valeria offered a barely perceptible smile, a calculating gesture that only Citlali managed to notice from the floor. “Very well,” Valeria declared, adjusting her expensive coat. “From this moment on, I assume absolute control of the food in this house. This indigenous woman is fired immediately. The girls will consume only the special synthetic formula that I will prepare personally. It costs 8,000 pesos per bottle, but it is the only way to save them. If there is even one deviation from my rules, the authorities will be here in 10 minutes.”

Feeling cornered and without options, Eduardo lowered his gaze. Heartbroken, he asked Mercedes to pay Citlali a month’s salary for the trouble and to ask her to leave. But the young woman from Oaxaca, her blood boiling with anger at the injustice, wasn’t about to abandon those two little ones. Citlali knew the cacao atole had reconnected them with life. She had seen the sparkle in Sofía and Isabela’s eyes. Instead of leaving through the mansion’s front door, Citlali took advantage of a moment of inattention from Mercedes and hid in the maid’s quarters, behind the laundry area.

For the next 12 hours, the mansion became a clinical hell. Valeria installed measuring equipment in the kitchen and forbade Eduardo from approaching the girls while she tried to force them to take her “special formula.” The twins’ cries echoed through the stone hallways. They rejected the grayish liquid with all their might, spitting it out and coughing. Eduardo remained locked in his office, drinking one glass of tequila after another, weeping in front of a photograph of Mariana.

At 2:00 a.m., silence finally enveloped the house. Citlali emerged from her hiding place, walking barefoot so as not to make a sound on the marble floor. Her intuition told her the answer lay in the Italian leather briefcase the doctor had left on the kitchen island. With trembling hands, but resolute in her purpose, Citlali opened the briefcase. Inside were files on other wealthy families from Polanco and Santa Fe, and a black case.

Upon opening the case, Citlali found three small, unlabeled bottles filled with a clear liquid, and a dosing syringe. Next to them was the infamous 8,000-peso formula. At that moment, Valeria entered the kitchen in a silk robe to pour herself a glass of water. Citlali quickly ducked behind the enormous industrial stove, holding her breath.

From her hiding place, Citlali pulled out her modest cell phone and activated the video camera. She watched as Valeria took one of the unlabeled bottles, extracted exactly 5 drops with the syringe, and injected them into the formula bottle she would use the next day.

“Poor girls,” Valeria whispered to herself, with a chilling hint of mockery. “They only need five more drops of this gastric suppressant to keep vomiting everything except my IV fluids. One more month of this charade, and Eduardo will be so desperate he’ll beg me to marry him so I can be his family’s savior. 180 million pesos is worth a little bit of childhood suffering.”

Citlali’s heart skipped a beat. The doctor was slowly poisoning the twins! She was chemically inducing aversion to food with a medication that caused severe nausea and suppressed their appetite, all to create absolute dependence and manipulate Eduardo into marriage.

Citlali saved the video, but as she tried to back up, she bumped into a metal pot. The metallic clang echoed through the kitchen. Valeria turned on the main lights and discovered the young woman from Oaxaca.

“You!” Valeria shouted, grabbing a chef’s knife from the table. “What are you doing here, you damned maid? I told you to get out!”

“I know what you’re doing to the girls,” Citlali replied, standing up bravely, without looking away. “You’re not a doctor, you’re a monster.”
