Chapter 7 - WHERE THEY BURIED THE BEGINNING

The abandoned San Gabriel mine sat beyond a dry valley where cell service faded and the road narrowed into pale gravel. By the time Aranda’s convoy reached the old property, evening had turned the mountains purple. Rusted equipment stood like skeletons against the horizon. The mine entrance had been sealed decades earlier, but satellite photographs showed recent tire tracks leading toward a maintenance building half a mile east. Natalia insisted on going. Lucía objected. “You are a witness, not an investigator.” Natalia answered quietly, “I am also the only person here who knows how my mother hides things.” In the end, she remained in the command vehicle while officers searched.
Sebastián stayed with her. Valeria and Mateo were safe at a protected medical apartment in Monterrey with Elena Morales and two officers. Leaving them, even for a few hours, had felt wrong, but Valeria had surprised him. “Go,” she said. “Not because your family deserves saving. Because the other women deserve evidence.” It was the first time since Mateo’s birth that she had entrusted him with something rather than merely accepted his presence. Sebastián understood the difference. He kissed her forehead, asked whether she was sure, and waited for the answer. “I’m sure,” she said. “And come back alive. I am still angry with you.”
The maintenance building looked empty. Then officers found a reinforced door beneath a trapdoor covered by mining dust. A narrow staircase descended into a climate-controlled chamber lined with metal cabinets. Archive B was not a metaphor. It was a blackmail library. Investigators found original medical forms, secret recordings, photographs, property transfers, letters from politicians and business executives, and signed agreements involving families far beyond the Alcázars. Some documents appeared to show legitimate settlements. Others suggested coercion. Lucía immediately ordered the room sealed and warned everyone against drawing conclusions before authentication. The significance, however, was obvious: Rebeca and Octavio had not survived through wealth alone. They had survived through leverage.
One cabinet was labeled NATALIA. Inside were years of reports, including records of every failed attempt she had made to contact the outside world. There were letters she had written to Sebastián that were never mailed. There were copies of forged responses supposedly from him, telling her to stop making accusations and accept treatment. Natalia stared at the pages through an evidence bag. “I thought you had abandoned me,” she said. Sebastián felt tears rise before he could stop them. “I thought you were dead.” Between them lay eleven years manufactured by other people, built letter by letter. Natalia looked away toward the dark mountains. “We lost the same years from opposite sides.”
A second cabinet carried Valeria’s name. Sebastián found surveillance photos taken outside their home, prenatal clinic notes, copies of private messages, and a psychological profile prepared by a consultant who had never met her. One line described Valeria as “socially isolatable due to limited integration with legacy family networks.” The phrase was monstrous in its simplicity. It meant she had fewer powerful relatives. It meant they believed she could be erased more easily. Another document proposed that after delivery, Sebastián should be told Valeria had experienced a psychotic episode and requested temporary separation. If he resisted, selected recordings could be edited to show her shouting during previous arguments.
Sebastián remembered those arguments. Valeria had accused Rebeca of entering their home without permission. She had accused nurses of following her. She had demanded that they change doctors. He had become frustrated, frightened by how certain she sounded. Rebeca had encouraged him to record “episodes for medical reasons.” He had done it twice. Now he saw transcripts of those private moments in the archive. Shame moved through him slowly, more painful than panic. He had not planned the trap, but he had handed them pieces of it. When he called Valeria from outside the mine, he told her the truth. There was a long silence. “Thank you for telling me,” she said. “We deal with it when you come home.”
The search also produced evidence that Octavio had been at the mine less than two hours earlier. A portable safe stood open. Several drives were missing. Fresh coffee remained in a thermos. Tire tracks led toward an old service road crossing the mountains into rural Coahuila. Then Aranda’s team found something stranger: Rebeca’s pearl earring on the floor near the safe, spotted with dried blood. Sebastián stared at it. His mother had been in custody after the Luz de Cuna fire. How could her earring be here? Aranda called Monterrey and learned that Rebeca had been transferred earlier that day for a court-ordered medical evaluation after complaining of chest pain. The transport vehicle had never reached the clinic.
Security footage showed a collision staged at an intersection. Two masked men forced open the rear door and removed Rebeca. The officers escorting her survived but were injured. The obvious assumption was that Octavio had arranged the escape. Yet the blood on the earring and the disorder inside the archive suggested the reunion had not been friendly. Natalia considered it. “Octavio has spent his life cleaning up my mother’s problems. If he thinks she is now the problem, he won’t protect her.” Sebastián felt no sympathy for Rebeca, but the thought of Octavio controlling her frightened him for another reason: desperate people exposed systems. Desperate people also destroyed them.
A hidden audio file from the mine computers provided the next clue. Recorded years earlier, it captured Octavio telling Álvaro that the maternal program had become “too valuable to remain a family tool.” He spoke about expanding services through private clinics in multiple countries. Álvaro objected. Rebeca’s voice interrupted, warning Octavio that he worked for the Alcázars, not himself. The recording ended with Octavio saying, “One day the name will need me more than I need the name.” Natalia leaned back in the command vehicle. “This was never just Mother.” The discovery complicated everything. Rebeca had been architect, participant, and enforcer—but Octavio had built his own empire inside hers.
Near midnight, Aranda received a trace from a burner phone linked to Sanz. It had connected briefly to a tower near an airstrip outside Parras. The same property housed a private hangar owned by a logistics firm tied to Octavio’s associates. Flight records showed a jet fueled for departure but not yet cleared. Police units converged from two directions. Sebastián was ordered to stay behind. This time he obeyed, not from fear but because Valeria’s words were still in his mind. Coming back alive mattered more than being present at every dramatic moment.

From a hill above the airstrip, they watched blue lights move across the darkness. A helicopter swept the runway with a white beam. Two vehicles attempted to flee through a rear gate. One stopped. The other crashed through a barrier and disappeared onto a dirt road. Minutes later Aranda received confirmation: Rebeca had been found inside the hangar, wrists bound, alive. Octavio was not there. In her coat pocket officers found a small drive she had apparently taken from Archive B. When asked why Octavio had abducted her, Rebeca gave no answer. She asked only one question. “Did Natalia open the letter from her father?”
Natalia heard the question over speakerphone and went still. “Why does she care?” Sebastián asked. Natalia looked toward the mine entrance where evidence teams continued carrying boxes into the night. “Because Father said not to trust the first archive.” She took out Álvaro’s note again. The final line suddenly seemed different. If Rebeca is cornered, she will go where we buried the beginning. Not where we buried the evidence. The beginning. Natalia looked at Sebastián. “The mine is not the beginning. Something happened before this program had a name.” And whatever it was, Rebeca feared Natalia discovering it more than she feared prison.
