The boy banged his cast against the wall, screaming, “They’re biting me!” while his father called him crazy and his stepmother demanded he be committed. The nanny remained silent, grabbed a pair of pliers from the garage, and broke the cast in front of everyone… never imagining that a hidden syringe would explain the horror.
PART 1
“If you keep screaming like that, Mateo, I’m taking you to a psychiatric hospital tomorrow, and you’re never sleeping in this house again.”
Carlos Rivera’s voice struck the bedroom harder than the thunder rolling over the old house.
Outside, rain beat against the windows of the Coyoacán mansion, turning the garden into a black blur of leaves, stone statues, and flooded pathways. Inside, ten-year-old Mateo sat on the edge of his bed, pale as paper, shaking so badly his teeth clicked together.
Then he raised his broken arm and slammed the white cast against the wall.
Knock.
Knock.
Knock.
The sound made Rosa freeze in the hallway.
She had worked for the Rivera family for twenty-two years. She had cooked for Carlos when he was a teenager. She had held Mateo when he was born. She had buried his mother’s favorite blue dress in a cedar box after the funeral because Carlos could not bear to touch it.
She knew the difference between a child throwing a tantrum and a child begging for his life.
This was not anger.
This was terror.
“Take it off!” Mateo screamed. “Please! They’re moving again! They’re inside!”
His eyes were wild from sleeplessness. His lips were cracked. Sweat rolled down his temples and soaked the collar of his pajama shirt.
His right arm, trapped in the cast from wrist to elbow, was stained along the edges. The plaster looked dirty where it met his skin, darkened by dried blood and something yellowish that Rosa did not want to name.
Carlos stormed across the room and grabbed Mateo by both shoulders.
“Enough!” he shouted. “Do you hear yourself? You sound insane!”
Mateo kicked against the bed frame.
“I’m not lying, Dad! They’re biting me!”
“There is nothing inside your cast!”
“There is!”
Carlos shook him once, not hard enough to injure him, but hard enough to make Rosa’s heart stop.
“You fell at school. You broke your arm. The doctor put on a cast. That is all that happened.”
Mateo turned his head toward the doorway.
Lorena stood there in a cream silk robe, her hair perfectly brushed, her face calm in a way that did not belong in a room where a child was screaming.
She was Carlos’s new wife.
Beautiful. Soft-spoken. Always composed.
And ever since she had entered the house, Mateo had become thinner, quieter, and afraid of rooms where she stood too close.
“I warned you,” Lorena said gently. “This is no longer normal grief.”
Carlos looked back at her, exhausted.
Lorena sighed as if Mateo’s pain embarrassed her.
“First he said the cast burned. Then he said something was crawling under his skin. Now he says he’s being bitten by invisible things. Carlos, he needs help.”
“I need a doctor!” Mateo cried.
“You saw a doctor,” Lorena said.
“You know what you did!”
The room went still.
Rosa saw it.
For half a second, Lorena’s calm face cracked.
Then she lifted a hand to her chest, hurt and offended.
“Carlos, listen to him. Now he’s accusing me. A child who makes accusations like that can destroy a family.”
Mateo began clawing at the opening of the cast with his good hand. He tried to force his fingers underneath the plaster. When that failed, he reached for a plastic school ruler on the nightstand and jammed it into the narrow space between skin and cast.
Rosa rushed forward.
“No, niño, stop. You’ll hurt yourself.”
“They’re under there!” Mateo sobbed. “Nana, please. Please get them out.”
Carlos ripped the ruler from his hand.
Then, in a decision that would haunt him forever, he took a leather belt from the closet and tied Mateo’s good wrist to the bedpost.
Mateo screamed.
Rosa stepped back as if she had been slapped.
“Señor Carlos,” she whispered, “don’t do this.”
“He’s going to hurt himself,” Carlos snapped.
“He is trying to escape pain.”
“He is trying to manipulate me!”
Lorena moved closer.
“Tomorrow morning,” she said, “we call the clinic. No more delays.”
Mateo went quiet.
Not calm.
Defeated.
That was worse.
His small chest rose and fell. His eyes found Rosa’s.
“Nana,” he whispered. “Don’t let them lock me away. I’m not crazy.”
Rosa felt something inside her break.
She leaned over him and placed a palm against his forehead.
Heat burned through her hand.
“He has a fever,” she said.
Carlos closed his eyes. “He has been screaming for three hours.”
“No. This is fever.”
Lorena gave a dry little laugh.
“Rosa, with respect, you are not a doctor.”
“No,” Rosa said, slowly turning toward her. “But I have cared for sick children longer than you have cared about this one.”
Lorena’s eyes hardened.
Carlos missed it.
Rosa did not.
Then the smell hit her again.
Not sweat.
Not rain.
Not damp plaster.
Something sweet, rotten, and infected.
Rosa pulled the sheet back and looked closely at the cast. The crack near Mateo’s elbow was darker than before. The skin around it was swollen and red.
Then something moved.
A tiny red ant crawled from the edge of the cast.
Rosa stopped breathing.
The ant crossed the sheet, turned, and disappeared back into the gap.
“Señor Carlos,” Rosa said carefully, “an ant just went into the cast.”
Carlos stared at her like she had betrayed him.
“What?”
“There are ants.”
Lorena’s voice sharpened. “Then the room is dirty.”
“Mateo has barely eaten in two days. There is no food in this bed.”
Another ant appeared.
Then another.
They came from the crack in the plaster, moving in and out as if the cast were not a medical dressing but a nest.
Carlos finally saw one.
His face changed.
Mateo began crying again.
“I told you,” he whispered. “I told you.”
Lorena stepped backward.
Only one step.
But Rosa saw that too.
For days, everyone had called the boy unstable. Dramatic. Difficult. Damaged by grief.
But three things now stood in front of the truth like witnesses.
The fever.
The smell.
The ants.
Rosa straightened.
She looked at Carlos.
“If you send this child to a psychiatric hospital without opening that cast, may God forgive you.”
Carlos looked uncertain for the first time.
Lorena recovered quickly.
“Absolutely not,” she said. “You cannot just break a cast open with household tools. You could injure him. We wait for a doctor.”
Rosa stared at her.
“Funny,” she said softly. “You were not this worried when he was begging for one.”
Then Rosa turned and left the room.
She walked through the dark service hallway, past the kitchen, past the pantry, and into the garage. Rain hammered the roof above her. The electricity flickered once, then came back weak and yellow.
She opened the old metal toolbox.
Her hand went straight to the pliers.
Heavy.
Cold.
Useful.
When Rosa returned, Carlos was standing beside the bed, pale and silent. Lorena held her phone in one hand, as if preparing to record evidence of Mateo’s “episode.”
Rosa stepped between them.
“Nana?” Mateo whispered.
“I’m here,” Rosa said.
Carlos raised a hand.
“Rosa, put that down.”
“No.”
“You have no authority to—”
“I had authority when I fed your son. I had authority when I taught him to tie his shoes. I had authority when I sat beside him the night his mother died because you were too broken to enter the room.”
Carlos flinched.
Rosa placed the pliers against the cast.
Lorena’s voice trembled.
“Stop.”
Everyone looked at her.
For the first time all night, she sounded afraid.
Rosa pressed harder.
The first crack split the room like thunder.
Mateo screamed, but not from fear.
“Break it!” he sobbed. “Please, Nana, break it!”
Carlos moved forward.
Rosa glared at him.
“Touch me, and you will have to explain to God why your son died while you protected your wife’s feelings.”
Carlos stopped.
The plaster cracked again.
A foul smell burst into the room.
Carlos staggered backward, gagging.
Lorena covered her mouth.
Rosa broke away a larger piece.
Red ants poured from the opening.
Mateo cried out as Rosa gently pulled back the blackened gauze beneath.
And there, wedged against Mateo’s swollen skin, hidden inside the cast where no child could have placed it himself, was the thin plastic barrel of a syringe.
Lorena whispered again.
“Stop.”
May you like
This time, Carlos heard her.
And everyone in that room slowly turned to look at her.
