PART 1
In the prettiest house in the Narvarte neighborhood, Iker’s screams no longer surprised anyone.
For six nights, he had woken everyone up, banging his cast against the bed frame, his face flushed with fever and his eyes wide open as if he were seeing something that others could not.
—Get it off me! —he shrieked—. They’re moving! They’re stinging me from the inside!
He was nine years old and had his right arm immobilized for three weeks after falling on the schoolyard during a soccer game.
At first, his dad, Andrés, thought it was just fear.
Then he thought it was a tantrum.
And later, because of Sofía, his new wife, he started to believe his son was using the cast to ruin his marriage.
—Here we go again —Sofía said from the door, wearing her pristine white robe with her hair tied up—. Andrés, this is no longer pain. It’s manipulation.
Iker glared at her with hate, but also with panic.
—You know! You know what happened!
Sofía let out a sad little laugh, the kind that made anyone seem guilty except her.
—See? Now he’s accusing me. Poor thing, but he needs help. You can’t keep allowing this.
Andrés entered the bedroom exhausted, his tie loose and his patience shattered. Ever since Mariana, Iker’s mom, had died, he had tried to keep everything together: private school, therapy, work, meals, meetings, birthdays, everything.
When Sofía appeared, sweet and calm, he thought there would finally be peace.
But that night, his son screamed as if he were being burned alive.
—Enough, Iker —Andrés said, grabbing him by the shoulders—. You’re going to hurt yourself worse.
—Dad, seriously, it burns! Something’s crawling inside!
—There’s nothing inside.
—Yes, there is!
Doña Chole, the nanny who had been with the family for 16 years, stood at the entrance with a cup of tea that had gone cold in her hands.
She had raised Iker since he was a baby. She had seen him cry over shots, nightmares, and the death of his mother. She knew his cries.
And this was not a cry of a spoiled child.
It was a cry of someone trapped.
—Mr. Andrés —she murmured—, the boy is burning up.
Sofía cut her off immediately.
—Chole, please. Don’t add more drama. You spoil him too much.
The nanny approached and changed the sweat-soaked pillow. Then she felt it.
A strange smell.
Sweet. Sour. Like rotten fruit mixed with an old wound.
Iker tried to stick a popsicle stick into the edge of the cast and scraped it until it bled.
—My boy, no —Chole said, taking it away from him.
—Nana, help me. She did something to me.
Andrés closed his eyes in anger.
—Don’t say that again.
Sofía put a hand on her chest.
—This has crossed a line, Andrés. Tomorrow, you’re calling the clinic. We can’t live hostage to his outbursts.
Iker shook his head, trembling.
—I’m not crazy...
Chole adjusted the blanket and then saw something moving on the fabric.
A red ant was walking straight toward the cast, crawling up the stained bandage and disappearing into a dark crack next to the inflamed skin.
Chole's mouth went dry.
—Sir... an ant just crawled into the cast.
Andrés looked at her, fed up.
—Then clean it better. I’m sure he left sweets everywhere.
—The boy has hardly eaten since the day before yesterday.
Sofía smiled slightly from the hallway.
Another ant emerged from under the cast and disappeared among the blankets before Andrés could catch a glimpse.
That night, while Iker begged not to be locked away, Doña Chole understood something that chilled her blood.
The boy wasn’t imagining monsters.
The monster lived inside that house.
PART 2
The next morning, Andrés came down with his cellphone glued to his ear and a blue folder under his arm.
He had barely slept for two hours. His face looked like that of a defeated man before the day even began.
—Yes, doctor, I understand —he said—. I’ll bring him today. Emotional assessment, yes. Urgent.
Iker listened from the stairs.
He came down slowly, hugging his cast against his chest. His lips were chapped and his skin pale, as if the fever had drained the life out of him.
—Dad, please —he whispered—. Don’t take me to that place.
Andrés hung up and tried to sound firm.
—It’s for your own good, son.
—I’m not crazy!
Sofía appeared behind Andrés and adjusted his collar.
—Honey, don’t get into his game. The more you explain, the more he gets hooked. You’ve seen how he’s breaking us.
Doña Chole slammed a pitcher of water on the table so hard that the glass jumped.
—Before you put him in a clinic, take him to the emergency room.
Sofía turned to her with fake patience.
—Chole, you’re not a doctor.
—I’m not a doctor, but I know when a child is sick. Smell his arm. Look into his eyes. That cast is bad.
Andrés hesitated.
And Sofía noticed immediately.
—What if you take him to the hospital and they see that the cast is injured? —she said in a low voice—. They’re going to think you neglected him. They’re going to call Child Protective Services. They can take Iker away from you, Andrés. Is that what you want?
The word Child Protective Services fell over the living room like a bucket of cold water.
Andrés stood still.
Fear did the trick that Sofía needed.
Iker approached Chole and squeezed her hand with his swollen fingers.
—Nana —he murmured—, bring me the big knife.
Chole felt her heart break.
—For what, my love?
—Cut off my arm. I don’t want it anymore. I swear I can hold it.
The nanny had to hold onto the railing.
A boy who once cried because he didn’t want cough syrup now preferred to lose an arm rather than stay in that hell.
—Don’t say that, sweetheart.
—Then believe me —Iker pleaded—. She put something in me.
Chole lifted her gaze.
Sofía was not scared.
She was watching.
That afternoon, while Andrés filled out forms for the clinic, Chole went up under the pretext of changing the sheets.
The bedroom smelled worse.
It wasn’t just sweat. It was something fermented, sticky, sick. The odor was coming from the cast as if a rotten fruit were hiding underneath.
Iker was no longer screaming.
That frightened her even more.
He lay there with his eyes half-open, breathing shallowly. His forehead burned. The skin around the cast looked red, damp, with black specks moving among the gauze.
—Nana... —he mumbled—. Are they gone?
—Who, my child?
—The ones who walk.
Chole swallowed hard, and she didn’t cry because there was no time.
She went down to the service patio and began to sift through the garbage. She wasn’t looking for food. She was looking for an explanation.
At the bottom of a black bag, she found hardened napkins, a nearly empty bottle of agave honey, and a jar of corn syrup for baking.
Everything was hidden beneath scraps of food.
Chole remembered that Iker hadn’t eaten anything sweet in days.
She tucked a sticky napkin into her apron pocket.
Then she heard Sofía’s voice behind her.
—Are you checking my trash now?
Chole straightened up calmly.
—I’m cleaning.
Sofía approached. Her expensive perfume barely masked her fury.
—Look, Chole, you’re getting old. It would be a shame for you to lose your job over making up stories. That child isn’t yours.
The nanny held her gaze.
—He doesn’t need to be mine for me to care.
Sofía’s smile vanished.
—Don’t get involved where you weren’t called.
Chole walked away without answering.
But from that moment, she knew she couldn’t wait to convince Andrés.
At midnight, the rain hit the windows again. The house fell silent, except for the clock in the living room and Sofía’s soft footsteps as she packed a suitcase.
The clinic would pick Iker up at 8 in the morning.
—You’ll see that in a few days he’ll be calmer —Sofía told Andrés, folding a pair of the boy’s pajamas—. This will help us all.
Andrés didn’t reply.
Something in his chest was beginning to feel wrong, but guilt, exhaustion, and fear wouldn’t let him think.
At 2:23, Doña Chole heard a dry thud.
Then another.
She ran to Iker’s room and found him convulsing on the bed.
The cast thudded against his chest. His eyes were rolled back. His mouth let out a small whimper, like a wounded animal.
—Holy Virgin! —the nanny shouted.
Andrés came out of his room.
—What’s happening?
But Chole was no longer going to ask for permission.
She went down to the garage, opened the toolbox, and took some heavy, rusty cutting pliers.
She ran back upstairs, entered the bedroom, and locked the door.
On the other side, Andrés banged on the door.
—Chole! Open up!
Sofía screamed:
—She’s crazy! She’s going to destroy his arm!
Chole knelt beside Iker and brushed the sweat-drenched hair from his forehead.
—Hold on, my boy. Your nanny is going to get you out of here.
She placed the pliers at the edge of the cast.
She squeezed with all the strength she had left.
Crack.
The first piece opened.
A brutal odor burst out all at once, so sweet and rotten that even Andrés stopped banging for a second.
Chole squeezed again.
Crack.
The line opened all the way to his elbow.
Iker groaned with purple lips.
—Do you see them, nana?
Chole looked inside and felt her legs buckle.
—Yes, my love. Yes, I see them.
And although it was a horrific scene, those words gave Iker peace.
Finally, someone believed him.
Chole inserted her fingers into the opening and pulled. The cast crumbled like old shell and fell to the floor.
Underneath, there was not just an infection.
There was living cruelty.
Iker’s arm was swollen, red, covered in wet wounds. There were dark patches, open skin, dried blood, and a shiny substance stuck to the gauze.
Among the folds crawled red ants.
There were also white larvae stuck to the sweet remains.
Chole screamed, not in disgust, but in rage.
In that instant, Andrés managed to break down the door.
He stormed in furious, ready to snatch the pliers away, but froze.
First, the smell hit him.
Then he saw the broken cast.
Next, he saw the ants escaping across the carpet.
And finally, he saw his son’s arm.
All his world collapsed around him.
—No... —he murmured.
Chole threw a piece of cast at his feet.
—Look closely, Mr. Andrés. Your son wasn’t making things up. He wasn’t crazy. They were eating him alive while you told him he was being dramatic.
Andrés covered his mouth.
He recalled every scream. Every threat. Every time he told him not to make a fuss. Every time he believed Sofía because it was easier than accepting his son’s terror.
He doubled over and vomited by the door.
Iker, half-conscious, let out a thread of voice.
—Dad... it was true.
Andrés fell to his knees.
—I’m sorry, son. I’m so sorry.
Chole didn’t let him sink.
—Call 911! And bring warm water. Now.
Andrés obeyed like a scolded child.
He carried Iker with trembling hands and took him to the bathroom. As warm water washed over his arm, every insect that fell into the drain felt like a sentence.
—I’m sorry, my boy —Andrés kept repeating—. Dad should have listened to you.
Chole called emergency services.
While she spoke, she saw Sofía standing in the doorway.
The woman was pale, but she wasn’t looking at Iker.
She was looking at the nightstand.
Chole followed that gaze.
She opened the drawer and found bandages, gauze, pills, little scissors, and at the bottom, a thick pastry syringe, the kind used for filling cakes.
The tip was sticky.
It had crystallized golden remnants.
Chole lifted it with a towel.
—Mr. Andrés.
He came out of the bathroom with Iker wrapped in a white towel.
Upon seeing the syringe, he stopped breathing.
—What is that?
Sofía stepped back.
—I don’t know. It must be from the kitchen.
—It was in the child’s medicine drawer —Chole said.
Andrés walked toward her slowly.
—What did you do to him?
Sofía tried to maintain her mask.
—Nothing. They’re making a show. Iker must have put sweets in there. You know how he is.
Iker opened his eyes slightly.
—She came in when you went to Querétaro —he murmured—. She told me that if I spoke, you’d send me away. She grabbed my arm. I felt cold. Then sticky. Then the ants came.
Andrés felt the blood drain from his face.
The trip to Querétaro.
Two weeks prior.
A work meeting.
Chole had gone to the doctor.
Sofía had been left alone with Iker.
Everything fit together with monstrous precision.
—You put honey inside the cast —Andrés said, almost voiceless.
Sofía clenched her jaw.
—It wasn’t that serious.
Chole stepped forward.
—It wasn’t that serious?
Sofía exploded.
—Since I married you, it’s all been Iker! Iker and his school, Iker and his grief, Iker and the picture of his mom, Iker and his therapies! I’m your wife too, Andrés. I wanted a family as well.
The silence was louder than the rain.
Andrés raised his hand, but stopped.
He wasn’t going to become another monster in front of his son.
He took the phone.
—I need an ambulance and a police unit —he said—. My son was assaulted inside my house.
Sofía tried to snatch the phone away, but Chole stood in the way.
—Don’t you dare.
—You’re nobody —Sofía spat.
Chole straightened up.
—I’m the woman who believed the boy.
The sirens arrived 11 minutes later.
The paramedics rushed upstairs and, upon seeing Iker’s arm, their expressions changed. They administered IV fluids, checked his fever, and covered the area with sterile gauze.
Andrés wanted to get into the ambulance.
Iker reached out his healthy hand toward Chole.
—Let my nanny come.
It hurt Andrés, but he nodded.
—Of course, son. She’s going with you. I’ll follow behind.
On the sidewalk, two police officers spoke with Sofía. She was crying, saying it was all a misunderstanding, that the nanny hated her, and that Iker had always been problematic.
But Andrés handed over the syringe, the sticky napkin, the jars, and the pieces of the cast.
—I also want a restraining order —he said—. And I’m going to report everything.
Sofía looked at him with hatred.
—Without me, you can’t handle that child.
Andrés looked at her in the rain.
For the first time, he didn’t see the elegant woman he thought he loved.
He saw someone capable of smiling while a child rotted beneath a cast.
—Without you, I almost lost him —he replied.
In the pediatric hospital, the doctors confirmed the nightmare.
Iker had a severe infection under the cast. The sweet mixture had kept moisture, attracted insects, and opened more wounds.
—If you had waited 24 more hours —the doctor said—, we would be talking about bone infection, amputation, or septic shock.
Andrés sat in the hallway and covered his face.
He didn’t seek comfort.
He didn’t deserve it.
Chole stood in front of the operating room, hands clasped, praying quietly.
The cleaning lasted over two hours.
When the doctor came out, Andrés nearly fell over as he stood up.
—Is my son okay?
—He’s stable. His arm is saved. He’ll need antibiotics, dressings, and therapy, but we got to him in time.
Chole closed her eyes.
—Thank God.
When Iker woke up, the first thing he saw was his nanny.
Then he saw his dad, sitting in a corner, destroyed by guilt.
—Is she gone? —he asked.
Chole stroked his hair.
—Yes, my boy. She’s gone.
Andrés approached slowly.
—Iker... I don’t know if you’ll ever be able to forgive me. But I’m going to spend my entire life listening to you. I failed you.
The boy looked at him for a long time.
He didn’t say “I forgive you.”
Not yet.
He only asked:
—Is she never coming back?
—Never —Andrés said—. I swear to you.
Iker closed his eyes.
—Then stay.
Andrés sat beside him and took his healthy hand. He cried without becoming a victim, without talking about his exhaustion, without justifying his blindness.
For the first time, he understood that being a father wasn’t paying for an expensive school, living in a nice neighborhood, or having a spotless house.
Being a father was believing a child when he said “it hurts,” even if that truth destroyed the perfect family.
Sofía was arrested days later. The investigation gathered purchases, messages, syrup remnants in the syringe, Chole’s testimonies, and the medical report.
In the building, everyone talked.
Some judged Andrés for not listening. Others said Chole was an angel. Many wondered how many children had told the truth while adults called them dramatic.
Weeks later, Iker returned home.
The bedroom was completely cleaned. Andrés threw out the bed, the carpet, the sheets, and everything that smelled of that night.
But he couldn’t throw away the guilt.
That he would have to carry.
Iker came back with his arm bandaged, without a cast, filled with marks that would take a long time to heal. He walked slowly but alive.
Chole was waiting for him with chicken broth, lemon gelatin, and a soft blanket.
When he saw her, he smiled for the first time in weeks.
—Nana, can I sit with you?
—As long as you want, my love.
Iker snuggled next to her.
Andrés watched them from the entrance.
Before, it would have hurt him that his son sought Chole first.
Now he understood.
Trust is not demanded.
It’s earned.
And he had lost it when it mattered most.
That night, the house fell silent.
But it was no longer a silence of fear.
It was a clean silence, with open doors, fresh water by the bed, and calm breathing.
Days later, Andrés asked Chole to stop calling him “sir.”
—You saved my son —he told her—. This house is also yours. Not as an invisible employee. As family.
Chole looked at Iker, who was playing with some toy cars, carefully using the hand he almost lost.
—I don’t need to own anything —she replied—. I just need that when a child says he’s hurting, someone believes him.
Andrés lowered his gaze.
—I’m going to remember that every day.
Iker raised his eyes.
—Me too.
The marks on his arm didn’t disappear completely.
But each one told a truth stronger than any lie.
Sometimes the monster doesn’t live in a child’s imagination.
Sometimes it lives in the comfort of adults who prefer not to look.
And that’s why, when a small person says “something is happening to me,” don’t silence them, don’t ridicule them, don’t send them to silence.
Because maybe their life depends on a single brave person who dares to break the cast of appearances.
