Javier said goodbye as always: impeccable, confident, with that serenity that made me feel protected. He said it was a work trip to Barcelona, just three days. It wasn’t the first time I’d traveled on business, so I didn’t suspect anything.

Before leaving, he closed the gate from the outside with a thick chain and a heavy padlock.

“The copy of the key is in my office,” he explained, “but the lock is a little stuck. It is better not to use it unless emergency. That way I am calmer.

I nodded without arguing.

On the terrace, Leo, my ten-year-old stepson, stood motionless in his wheelchair. The head bowed, the gaze lost, the fragile body. The doctors had been clear: irreversible brain damage, total paralysis, no speech.

Javier looked at him with that sadness that I always thought was sincere.

“Take good care of him,” he said. It’s the only thing I have left of her.

Then he got into the car and drove off.

Silence fell on the house like a slab.

The routine and the first smell

At ten in the morning the usual routine began: diaper, food, cleaning, stories. Javier did not allow caregivers or visitors. She said it was for privacy, that she didn’t want strangers watching her son’s “misfortune.”

While I was reading him a story, a strange smell came to my nose. At first slight, almost imperceptible. Then he came back, stronger.

I checked Leo’s diaper by reflex. It was clean.

I went to the kitchen. Everything seemed normal: the ceramic hob off, the controls off. I told myself that it was my imagination. Javier used to say, laughing, that I was distracted, paranoid, unable to notice the important details.

But the smell returned.

And this time it was unmistakable.

Gas

The dizziness came suddenly. A pressure on the head, a heavy, unnatural sleep. I staggered to the cupboard where the gas bottle was.

As soon as I opened the door, I heard the hiss.

The regulator was crooked.

I tried to adjust it, but my hands were shaking. My legs stopped responding to me. I fell to the kitchen floor, my heart pounding and my eyes darkening.

I thought of Leo.

I thought I wasn’t going to be able to save him.

Leo Rises

Then I heard wheels.

Then steps.

Firm steps.

Someone leaned over the cylinder. Fast, safe hands. The regulator was torn off and the hiss stopped.

I strained my eyes.

It was Leo.

Standing.

No saliva. No twisted neck. With a clear, alert, adult gaze.

“Don’t scream,” he whispered. Hold your breath. Dad wanted to kill us today.

The air returned to my lungs like a brutal blow. I coughed, cried, clung to the ground.

And reality was broken.

The truth is starting to fit

Leo opened the windows, turned on the fans, and calmly gave me water.

“It wasn’t an oversight,” the regulator said, pointing to it. Look at the scratches. They used a screwdriver. The rubber gasket is missing.

I denied, still stunned.

“Dad would never forget something like that. He is meticulous to the point of obsession.

Then he listed everything with unsettling precision: the gate locked from the outside, the windows sealed before leaving, the order not to go out, the recently renewed life insurance.
