Chapter 6 - The Girl Who Heard the KnocksAt first, the ringing sounded like coincidence.
A nurse’s phone. Then another. Then a police radio. Then Detective Duarte’s cell phone vibrating so violently against his palm it nearly slipped from his hand.
He answered. His face changed before he said a word.
Mateo had seen that look already that night.
It was the look people wore when horror moved faster than they could explain.
Duarte turned sharply toward the door. “Lock down this floor.”
Laura stood. “Why?”
Duarte spoke into the phone. “Where was he last seen?”
Mateo stepped closer. “Detective.”
Duarte held up one hand, listening.
Then he looked at Jimena.
Mateo moved instantly, placing himself between the detective’s gaze and his daughter.
“What happened?” Mateo demanded.
Duarte lowered the phone. “Santiago’s attorney arrived at the station twenty minutes ago.”
“So?”
“Santiago asked to make a statement. While being transferred to an interview room, he collapsed.”
Laura’s brow tightened. “Collapsed?”
“Poison,” Duarte said. “Or something meant to look like it. He’s in critical condition.”
Mateo felt no sympathy. “Why does that put my daughter in danger?”
“Because before he collapsed, he said two words.”
The room went still.
Duarte looked at Jimena again.
“Second child.”
Laura’s face twisted. “No.”
Emiliano began shaking his head on the pillow. “He said he would. He said he would.”
Mateo turned to Duarte. “Who else knew we were here?”
“Too many people. Police. Hospital staff. Neighbors. Your mother. Your wife’s sister. Anyone following the story online by now.”
Mateo stared. “Online?”
Duarte’s mouth hardened. “Someone leaked footage from outside Rebeca’s house. It’s spreading.”
Laura looked sick. “Our son was rescued hours ago.”
“And people are already turning it into entertainment,” Duarte said.
Mateo’s phone buzzed. Then Laura’s. Then another notification. Mateo did not look. He could not bear to see headlines, comments, theories. His child’s prison reduced to a post for strangers to react to with broken heart emojis.
Dr. Moya stepped toward Jimena. “We need to move both children somewhere secure.”
Duarte nodded. “Already arranged.”
But Jimena had gone strangely calm.
She slid off the chair and walked to Emiliano’s bed. “He can’t take me,” she said.
Mateo knelt in front of her. “No one is taking you.”
“He can’t,” she repeated. “Because I know where the other knocks came from.”
Duarte looked at her carefully. “Other knocks?”
Jimena glanced at Emiliano.
Her brother whispered, “Tell them.”
The little girl hugged herself. “When we were at Tía’s house today, Emi knocked from under the floor. But there was another sound too.”
Mateo felt cold again. “What sound?”
She pointed downward.
“Water.”
Duarte frowned. “Water pipes?”
“No,” Jimena said. “Like the fountain at Abuela’s house. Drip, drip, drip. Then one knock. Then water again.”
Laura looked confused. “Sweetheart, what does that mean?”
Jimena turned toward her mother. “At Abuela’s house, before Emi disappeared, I heard that sound behind the laundry room.”
The adults went silent.
Coyoacán.
The grandmother’s house.
The place where everything began.
Mateo stood slowly. “You heard knocking there?”
Jimena nodded. “I thought it was the pipes. Emi told me Tomás sang in Tía’s apartment. But at Abuela’s, someone knocked by the laundry sink.”
Laura whispered, “The sneakers.”
Mateo looked at her.
“When Emiliano disappeared,” she said, voice trembling, “his sneakers were found beside the laundry sink.”
Duarte moved fast. He stepped into the hallway and began issuing orders into his radio.
Mateo followed. “You think there’s another hidden room in my mother’s house?”
“I think Santiago did not choose your family randomly,” Duarte said. “And I think your mother’s house needs to be searched immediately.”
“My mother is seventy-two.”
“I’m not accusing her.”
Mateo said nothing.
Because the terrible truth was this: he no longer knew who could be trusted.
Within the hour, Mateo, Laura, Jimena, and Emiliano were moved under police protection to a private wing. Officers were posted at the elevators, stairwells, and doors. Emiliano cried when they wheeled him away from the room, so Mateo walked beside him the entire time, one hand visible, speaking softly.
“You’re going to a safer room.”
“Is it upstairs?” Emiliano asked.
“Yes.”
“No floor doors?”
“No floor doors.”
Jimena walked with Laura, but her eyes kept scanning the walls.
The girl who had been dismissed as frightened now seemed like the only person who had truly been paying attention.
At 9:40 a.m., Duarte called Mateo from outside the grandmother’s house in Coyoacán.
Mateo answered on speaker because Laura grabbed his wrist and would not let him hide anything.
“We’re inside,” Duarte said.
Mateo could hear voices behind him, footsteps, drawers opening.
“And?”
“There is a cellar beneath the laundry room.”
Mateo’s knees almost gave out.
Laura sat down hard on the edge of Emiliano’s bed.
“My mother doesn’t have a cellar,” Mateo said.
“She does,” Duarte replied. “Sealed behind a false cabinet.”
Jimena began to cry.
Emiliano shut his eyes.
Duarte continued. “No child inside. But there are signs someone was held here before. Recently.”
Mateo gripped the phone. “How recently?”
“A mattress. Rope. Water bottles. A child’s sock.”
Laura whispered, “Oh God.”
“And Mateo?”
“What?”
“We found a wall covered in names.”
Mateo could barely hear over the blood rushing in his ears.
“One of them is Emiliano,” Duarte said. “Written at child height.”
Emiliano opened his eyes.
“I wrote it,” he whispered.
Mateo looked at him.
His son’s voice was hollow. “Before Tía took me to the apartment. Santiago kept me there first.”
Laura stood, shaking. “Your mother said she searched every room.”
Mateo did not answer.
Because he remembered his mother that day, sitting in the patio while everyone screamed Emiliano’s name. He remembered her rosary wrapped around her fingers. Her face pale. Her voice saying, “Maybe he wandered outside.”
Maybe.
That word had held his family together for a year.
Now it began to rot.
Duarte’s voice came through again. “Your mother isn’t here.”
Mateo stiffened.
“What do you mean she isn’t there?”
“Neighbors say she left fifteen minutes before we arrived.”
Laura looked at him.
Mateo ended the call and dialed his mother.
It rang once.
Twice.
Then she answered.
“Mamá,” Mateo said carefully. “Where are you?”
There was wind on the other end. Traffic. A bus engine.
His mother’s voice shook. “I’m sorry, hijo.”
Mateo closed his eyes.
“What did you do?”
“I thought they would kill him,” she whispered. “I thought if I stayed quiet, they would give him back.”
Laura covered her mouth.
“Mamá,” Mateo said, “where are you?”
A pause.
Then his mother began to sob.
“He has my granddaughter.”
The room turned to ice.
Mateo looked across the bed.
Jimena stood beside Laura.
Safe.
Present.
Confused.
Mateo spoke slowly. “Jimena is here.”
His mother’s crying stopped.
On the other end, a child screamed.
Not Jimena.
Another girl.
Then an unfamiliar man took the phone and laughed softly.
May you like
“Wrong granddaughter, Mateo.”
The call ended.
