“If you keep screaming like this, Mateo, I’m going to sign the papers to have you committed today.”
That was what Carlos said with a broken voice, standing in the doorway of his son’s bedroom while the ten-year-old boy slammed the cast on his arm against the wall as if he wanted to tear his life away along with that white thing.
It was nearly two in the morning in a large house in Coyoacán, and the dry sound of plaster hitting the wall echoed through the hallways like an alarm.
Thud. Thud. Thud.
Mateo’s face was soaked with sweat, his eyes wide with terror, and his lips cracked from crying so much.
Carlos rushed toward him, not with tenderness, but with the furious exhaustion of a man who had gone nights without sleep. He grabbed Mateo by the shoulders and shoved him onto the bed.
Mateo was trying to shove a pen under the edge of the cast. He scratched desperately, as if there were fire underneath. The skin around the bandage looked irritated and stained, but Carlos refused to look too closely anymore. He no longer knew what to believe.
Lorena, his wife, appeared leaning against the doorframe. She wore an elegant robe, her hair flawless, her face cold.
“I told you, Carlos,” she murmured. “This isn’t pain. It’s manipulation. Ever since you married me, Mateo hasn’t been able to stand sharing you.”
“Liar!” the boy screamed. “You know what you did!”
Lorena widened her eyes with fake sadness.
“You see? Now he’s accusing me. That’s paranoia. He needs psychiatric help before he really hurts himself.”
Carlos breathed heavily. He looked at his son, then at Lorena. Ever since the accident at school, everything had become unbearable. The doctor had said the cast would only cause a little discomfort, nothing more. But Mateo wouldn’t eat, wouldn’t sleep, trembled, sweated, and talked about “little legs” moving beneath his skin.
Rosa, the nanny who had worked in the house for years, watched from the hallway with a tightness in her chest. She had noticed something different. A strange smell in the room. It wasn’t sweat. It wasn’t old plaster. It was a sweet, heavy odor mixed with something rotten.
When she leaned over to change the sheets, she saw a tiny red ant crossing the pillow. It wasn’t heading toward the floor. It walked straight toward the opening in the cast and disappeared inside.
“Mr. Carlos…” Rosa said, pale. “There’s something inside.”
Carlos let out a bitter laugh.
“He’s probably hiding candy in there. Clean properly and stop putting ideas in his head.”
Mateo looked at her with tears in his eyes.
That same night, Carlos took a belt and tied his son’s healthy wrist to the bed so he would stop hitting himself.
And Lorena smiled faintly, as if everything were unfolding exactly the way she had planned.
PART 2
The next morning, Mateo no longer had the strength to scream. That was what frightened Rosa the most.
She found him staring at the ceiling, his lips dry and his forehead burning with fever. His casted arm rested on the bedsheet, but his fingers were swollen and trembling. The boy looked smaller than ever.
“Nana…” he whispered. “Go get the big bread knife.”
Rosa leaned closer, thinking she had heard him wrong.
“What did you say, sweetheart?”
Mateo looked at her with a clarity that froze her blood.
“Cut my arm off. I don’t want it anymore. I promise I won’t scream.”
Rosa had to cover her mouth to stop herself from crying. No child asked for something like that out of a tantrum. No child would rather lose an arm than keep wearing a cast unless something terrible was happening underneath.
She walked into the hallway and confronted Carlos.
“Sir, he has a fever. It smells bad. This isn’t psychological. Take him to the emergency room.”
Carlos held his phone in his hand. On the table were admission papers for a private psychiatric clinic in Santa Fe. Lorena stood beside him, stroking his shoulder.
“Rosa, you don’t understand,” Carlos said, shattered. “Last night he almost broke his arm against the wall. He says imaginary things are biting him.”
“They’re not imaginary,” Rosa insisted. “I saw an ant crawl into the cast.”
Lorena let out a tired sigh.
“For God’s sake, Rosa. One ant doesn’t cause a breakdown like this. Besides, if they take him to a hospital and see those wounds, they’ll accuse Carlos of negligence. Do you want him arrested?”
Carlos lowered his gaze. That sentence paralyzed him.
Lorena knew exactly where to strike. For days she had repeated that Mateo could destroy his reputation, his job, his life. She told him the boy was jealous, that he was hurting himself to blame her, that he needed confinement and sedation.
But Rosa began remembering details that didn’t fit.
Three days earlier, when Carlos had traveled to Monterrey for work, Lorena asked Rosa not to enter Mateo’s room because “the boy needed discipline.” That same afternoon, Rosa found a large syringe in the kitchen—the kind used to inject marinade into meat—half washed. She also noticed a nearly empty jar of honey and sugar scattered across the counter.
At the time, she thought nothing of it. Now it all felt like a warning.
By afternoon, Mateo got worse. He started convulsing from pain. He no longer begged, insulted, or defended himself. He only clenched his teeth while silent tears ran down his temples.
Rosa realized that if she waited for permission, the boy might die.
When the storm hit the city, she went down to the garage. She searched through Carlos’s tools until she found a pair of heavy industrial pliers. She hid them beneath her shawl, entered Mateo’s room, and locked the door behind her.
Carlos heard the lock click.
“Rosa? What are you doing?”
Lorena shouted from behind him:
“She’s gone crazy! She’s going to hurt him!”
Rosa took a deep breath. Mateo looked at her without fear, only hope.
“Hold on, my love,” she whispered. “I’m going to take out whatever is killing you.”
She placed the pliers against the edge of the cast.
Crack.
The first break sounded as if the entire house had split apart.
And then, through the opening, came a smell so sweet and rotten that Rosa realized the truth was far worse than she had imagined.
PART 3
Carlos kicked the door open just as the cast finally split apart.
He stormed in, furious and ready to pull Rosa away from his son, but he froze halfway across the room. The smell hit him first. Then he saw Mateo’s arm.
It wasn’t a simple irritation. Beneath the cast was a dark, sticky mixture with traces of honey, inflamed skin, and tiny red ants crawling through the inner bandages. Some white larvae twisted in the worst area of the wound. Mateo had not imagined anything. He wasn’t crazy. He had been slowly devoured beneath a white prison everyone had called “treatment.”
Carlos covered his mouth with one hand and dropped to his knees.
“No… no, son… forgive me…”
Rosa, crying with rage, kicked the broken piece of cast toward him.
“Look at it, sir! That’s what was driving him insane! And you were going to send him to a mental institution!”
Carlos could not answer. He picked Mateo up as carefully as he could and rushed to the bathroom. Under warm running water, he gently cleaned the boy’s arm while repeating over and over:
“Forgive me, champ. Forgive me. Dad was an idiot.”
Mateo barely sobbed. He was too exhausted to speak.
Lorena tried to back away into the hallway. She wanted to disappear quietly, but Rosa saw her.
“Check the medicine drawer,” the nanny said with a trembling voice. “The bottom one.”
Carlos returned with a towel and opened the drawer. There was the culinary syringe. Crystallized traces of honey and sugar still clung to the tip.
The silence that followed was horrifying.
Lorena raised her hands.
“Carlos, it’s not what it looks like. It was a home remedy. My grandmother used to say honey helped—”
Carlos grabbed her by the arm.
“You injected honey into my son’s cast?”
“I just wanted him to stop acting like a victim.”
“He’s ten years old!”
Carlos’s voice exploded through the entire house. For the first time, Lorena had no prepared answer. The mask of the patient, elegant woman fell away completely. Her eyes hardened with resentment.
“Ever since I arrived, that boy hated me. Always looking at me like I was an intruder. Always reminding you of your dead wife.”
Carlos let go of her as if she burned him.
“You weren’t jealous. You wanted to destroy him.”
That night, an ambulance took Mateo to the hospital. Doctors confirmed he had a severe infection and that if they had waited one more day, the damage could have been irreversible. He needed surgery, deep cleaning, and weeks of recovery.
Lorena was arrested after Carlos handed over the syringe, the cast, and Rosa’s testimony. She tried to claim everything was exaggerated, that Mateo was disturbed, that Rosa had staged the scene. But the hospital, the evidence, and the child himself told a different story.
Months later, Mateo returned home. His arm carried scars, but also strength. Carlos sold the house filled with terrible memories and moved with him to a smaller home in Querétaro. Rosa went with them, no longer as an employee, but as family.
One afternoon, Mateo hugged his nanny with his healed arm.
“You believed me,” he told her.
Rosa stroked his hair.
“Sometimes, my child, saving someone begins with listening to what everyone else would rather ignore.”
Carlos watched them from the doorway, tears in his eyes. He knew the guilt would never completely disappear. But he also knew justice had begun the day a humble woman dared to break open a cast…
“If you keep screaming like this, Mateo, I’m going to sign the papers to have you committed today.”
That was what Carlos said with a broken voice, standing in the doorway of his son’s bedroom while the ten-year-old boy slammed the cast on his arm against the wall as if he wanted to tear his life away along with that white thing.

Thud. Thud. Thud.
Mateo’s face was soaked with sweat, his eyes wide with terror, and his lips cracked from crying so much.
“Take it off! Dad, please! They’re getting inside! They’re biting me!”
Carlos rushed toward him, not with tenderness, but with the furious exhaustion of a man who had gone nights without sleep. He grabbed Mateo by the shoulders and shoved him onto the bed.
“Enough! You’re going to break your arm again!”
Mateo was trying to shove a pen under the edge of the cast. He scratched desperately, as if there were fire underneath. The skin around the bandage looked irritated and stained, but Carlos refused to look too closely anymore. He no longer knew what to believe.
Lorena, his wife, appeared leaning against the doorframe. She wore an elegant robe, her hair flawless, her face cold.
