The door slammed open with a dry creak.

A cloud of snow and wood chips invaded the room.

Carmen screamed. The little girl began to cry. Don Ramiro covered his wife with his body as the wind rushed into the house like a rabid animal, knocking over a chair, extinguishing a candle, and hurling the cold at everyone.

“Move!” Elena shouted with a strength she didn’t even know she possessed. “Now!”

He didn’t wait for anyone to react.

She scooped Carmen’s granddaughter up in her arms and ran toward the kitchen. She pushed open the back door with all her weight. Outside, the yard was a white mess. The snow was almost knee-deep, and the wind cut her face like tiny knives.

Behind her came the others, stumbling, panting, dragging the older ones along, carrying what little they had managed to bring.

The small wooden cabin was barely visible in the storm.

For months it had looked like a ridiculous shed.

That night was the only hope.

Elena arrived first. She moved aside the shovel and an old crate she used to disguise the entrance. She lifted the trapdoor hidden under the floor of the shed, revealing the sloping ladder that descended into the darkness.

—One by one! Quickly!

Carmen went downstairs with the girl.

Then Ramiro’s wife.

Then an old man who could barely stand.

The wind roared louder. A few meters away, a huge pine tree bent almost to the ground and finally uprooted itself with a terrifying crash.

Elena was telling the story.

One.

Two.

Three.

Nine.

Two were missing.

Ramiro was pushing Tomás, the blacksmith, who had frozen, staring towards the village.

“My son!” cried Thomas. “My son isn’t here! He went out to close the stable!”

Elena felt something pierce her chest.

—How long ago?

—I don’t know! Ten minutes! Maybe more!

Ten minutes in that storm could feel like an eternity.

“Get down,” Elena ordered.

—Not without him!

Another crash echoed through the mountain. This time closer. Much closer.

The ground shook again.

Elena looked at the shelter.

He looked at the hillside.

He looked at Tomás.

And he saw in their eyes the same despair that he had seen in his own the day they found Mateo’s body among the trees.

He had no choice.

He handed the flashlight to Ramiro.

—Put them all in and close up when I get back.

“You can’t come out now!” Carmen shouted from downstairs.

But Elena was already running.

The snow pounded against her face so hard she could barely open her eyes. The village had almost vanished behind a white curtain. Only blurry shadows, covered rooftops, fallen posts, and branches whipped by the wind were visible.

“Ivan!” shouted Tomas from behind her. “Ivan!”

There was no response.

Only the howl of the storm.

They arrived at Thomas’s old stable, a low stone building at the side of the road. The door was ajar, one of the hinges having given way. Inside, two goats were bleating in terror. A broken lantern swung in the air.

And there, on the ground, was the boy.

Ivan.

He would be seventeen years old.

One of his legs was trapped under a fallen beam and his face was covered in blood.

“Dad…” he murmured when he saw them. “I tried to let go…”

Thomas fell to his knees.

—Help me!

Between the two of them, they lifted the beam just enough to pull the boy out. Ivan screamed in pain. Elena knew from the impossible angle of his leg that it was broken.

And in that same second he heard a sound that didn’t come from the wind.

A deep roar.

Continuous.

Deep.

The mountain going down.

—Now! —Elena shouted.

Tomás hoisted his son onto his shoulders and they staggered out. They had barely crossed half the yard when the avalanche of snow, mud, and logs swept the barn away as if it were made of paper.

The impact threw them to the ground.

Elena tumbled several meters downhill. The world turned white, then black, then white again. She felt snow in her mouth, inside her coat, in her eyes. She didn’t know where she was up or down.

Gesticulation.

He touched wood.

Then air.

Then nothing.

Until a huge hand grabbed her wrist.

It was Ramiro.

I hadn’t gone down to the shelter.

I had gone out to look for them.

“Get up!” he roared, pulling her along. “The houses are being buried!”

Tomas was still standing, miraculously, with Ivan hanging off his back.

They ran.

It was neither an elegant nor a heroic race.

It was a clumsy, desperate, brutal escape.

They were stumbling.

They were falling.

They were getting up.

When they reached the shed, half the roof was already covered with snow. Ramiro opened the trapdoor and practically threw Iván down, where several hands caught him.

Thomas came down next.

Elena was about to get off last when she instinctively turned her head.

And then he saw it.

The house.

His house.

The house where she had lived with Mateo.

The house where they had planned to grow old together.

The house where she had cried alone for three winters.

He saw it creak.

Lean.

And disappear under a dirty wave of snow, mud, and logs.

She didn’t have time to cry.

Ramiro pushed it down and closed the trapdoor just as something heavy hit the shed from outside.

Darkness enveloped them.

For a second, only gasps, cries, and the distant drum of the storm beating on the earth could be heard.

Then Carmen lit an oil lamp.

The flickering light illuminated the shelter.

It was small, but solid.

The reinforced wooden walls held up.

The shelves were still standing.

There were blankets, water, jars of preserves, sacks of potatoes, a box of candles, dry coal, and the old iron stove in a corner.

Everything that the people had ridiculed.

Everything that now kept them alive.

Nobody said anything for a long time.

Ramiro’s wife began to cry silently.

Thomas hugged his son, who was trembling with pain and fever.

Carmen squeezed Elena’s hand so hard it almost hurt.

“You saved us…” she whispered.

Elena did not respond.

Her gaze had been fixed on something that stood out next to the stove.

A metal box.

I didn’t remember her there.

He frowned.

She approached slowly and pulled back an old blanket covering it. The box had Mateo’s initials engraved on one side. MV

His mouth went dry.

She knew that box.

Mateo kept it in the workshop and never opened it in front of anyone.

“What’s wrong?” Ramiro asked.

Elena bent down.

The lock was broken, as if someone had forced it before.

He lifted the lid.

Inside were forest maps. A pocket watch. A rusty knife. Several papers wrapped in waxed cloth.

And, at the bottom, an envelope with his name on it.

“Elena”.

Her fingers began to tremble.

“Is it Mateo’s?” Carmen asked in a low voice.

Elena nodded.

He carefully opened the envelope.

Inside there were several folded sheets of paper and a photograph.

When he saw the image, he felt the air disappear from the shelter.

It was Matthew.

But he was not alone.

Beside him was a boy of about eight or nine years old, with a red scarf around his neck and a serious, almost frightened expression.

Behind them was a mountain cabin that Elena did not recognize.

He turned the photo over.

On the back, in Mateo’s handwriting, there was a phrase that left her frozen:

“If anything happens to me, find the child before they find him.”

Ramiro took a step closer.

—What does that mean?

Elena swallowed and turned to the letter.

Mateo’s handwriting was hurried, irregular, as if written under pressure.

“Elena,

If you’re reading this, it’s because I couldn’t explain it to you myself. What happened in the forest wasn’t an accident. For months I’ve been following tracks that don’t belong to animals or hunters. People are coming in from the north side of the mountain at night. They’re not coming to cut firewood. They’re not coming to hunt.

They’re looking for something.

And I think they’ve already found it.

Two weeks ago I found a boy hiding near the old stream. He was alone, freezing, and terrified. He wouldn’t tell me where he came from, but he kept repeating the same word: ‘basement’.

I hid him in the winter cabin to protect him. I promised to come back for him.

If I don’t come back, don’t trust anyone in town until you know who works for them.

Because someone here has been warning them.”

The entire shelter fell silent.

Even their breathing seemed slower.

Thomas was the first to speak.

—That can’t be true.

“It’s Mateo’s handwriting,” Elena said without taking her eyes off the paper.

Ramiro turned pale.

—’They’? Who are ‘they’?

Elena continued reading.

“The cabin is marked on the big map. If winter comes early, the shelter will be safer than the house. I left supplies there, and this too. Don’t open the box in front of anyone. If anyone asks about me, tell them you didn’t find anything.”

Elena stopped.

The last line was written with such pressure that it almost tore the paper.

“And if Don Ramiro insists on entering the workshop, don’t give him the key.”

They all turned towards Ramiro.

Nobody breathed.

The man took a step back, as if he had been hit.

-That…?

Carmen let out a muffled murmur.

Tomás stood up abruptly.

—What did you do?

“Nothing!” Ramiro raised his hands, pale. “I didn’t do anything!”

—Mateo mentioned you— Elena said.

“Because we argued, yes. The whole town knew it! He accused me of wanting to buy his land for next to nothing after he died. That was all.”

But Elena stared at him.

He remembered something.

Two weeks after the funeral, Ramiro had gone home.

He had asked her if Mateo had left her papers from the forest.

She, broken by grief, didn’t even understand why he wanted to know.

He said no.

And he had insisted.

At that moment, Ramiro saw in her face that she had remembered.

“It wasn’t because of me,” he said quickly, almost desperately. “Listen. Yes, I went to ask. But it was because Mateo arrived at the store one night, terrified. He asked me for batteries, rope, and canned food. He said that if anyone asked for him, he hadn’t been there.”

Tomás took another step forward.

—And why didn’t you say so before?

Ramiro lowered his gaze.

—Because he turned up dead the next day.

The impact of those words fell on everyone like a stone.

—And because I was the last one to see him alive.

Elena felt nauseous.

Ramiro continued speaking, faster now, as if he had been holding that in for years.

—The Civil Guard said it was an accident. A slip. A blow to the head. The end. But I didn’t believe it. He had the face of someone they’d been following. Then strange men started showing up, buying things at the store. They weren’t from around here. They were always asking about old roads, the northern part of town, the closed mines. I kept quiet because I have a family. Because I was scared.

Tomás clenched his fists.

-Coward.

—Yes —Ramiro replied, his voice breaking—. I was a coward.

Ivan groaned in pain and broke the tension for a moment.

Carmen ran to dampen a cloth.

Elena spread the map out on the makeshift table next to the stove.

There it was.

A red circle marked by Mateo, north of the old stream.

“The Winter Cabin.”

And further up, another place marked with a cross.

“Mine entrance”.

His pulse quickened.

“The mines…” murmured Tomás. “They closed forty years ago.”

“Not all of them,” Ramiro said in a low voice.

Elena looked up.

—What do you know?

Ramiro hesitated for only a second.

“My grandfather worked there. He said some tunnels were never registered. They were used to extract undeclared ore and hide merchandise after the war. If someone wanted to move things through the mountain without being seen…”

—I would use those mines—Elena finished.

The wind continued to roar above them, but now the real cold was inside the shelter.

It wasn’t the storm.

It was the idea that Mateo had discovered something much worse than a savage winter.

And perhaps that’s why he had died.

Carmen’s little girl, wrapped in blankets, suddenly pointed to the back wall.

-What’s that?

Everyone looked.

Behind a barely visible bookshelf, there was a rectangular slit in the wood.

Elena frowned.

I had never done that before.

He approached.

He pushed the bookshelf between Tomás and Ramiro.

A small recessed door appeared.

No more than half a meter wide.

Hidden.

No door handle on the outside.

His heart pounded so hard he had to lean against the wall.

“I didn’t build this,” he whispered.

—So, who? —Carmen asked.

Elena already knew.

Matthew.

He put his fingers in the slot and pulled.

The door opened with a dry groan.

An old, damp smell, locked away for years, came out of the darkness.

Inside there was a narrow compartment.

And on the floor, wrapped in a rotten blanket, there was something small.

At first Elena thought it was a box.

Until the lamp illuminated a hand.

A human hand.

Small.

As a child.

Carmen screamed.

Tomás suddenly stepped back.

Ramiro crossed himself, his face contorted with worry.

Elena fell to her knees, unable to breathe.

Next to the small body was another envelope.

With a single sentence written by Matthew:

“I arrived too late.”

For several seconds nobody said a word.

Outside, the mountain continued to roar.

Inside, the past had just opened up beneath their feet.

Elena took the envelope with icy hands and opened it crying without realizing it.

There was only one leaf.

“I hid him here so they wouldn’t find him until I could notify the correct authorities. If anything happens to me, I want the truth to come out. The boy said he wasn’t the only one. There are more down below.”

The entire shelter was filled with a monstrous silence.

Below.

Not in the village.

Not in the cabin.

Below.

In the mine.

Tomás was the first to react.

—When the storm subsides, we’ll go to the Civil Guard.

Ramiro closed his eyes.

—What if the person who warned us is still in town? What if it wasn’t just one person?

Elena got up slowly.

Her face was wet with tears, but her voice was firm.

She was no longer the woman everyone had seen digging alone behind her house.

Now she looked like a different person.

Harder.

Clearer.

More dangerous.

“Mateo didn’t die in an accident,” she said. “And neither did that child. My husband tried to save him alone. I’m not going to make the same mistake.”

He looked at the map.

Then the hidden compartment.

Then to the neighbors who had arrived at his door begging for refuge.

—When the sun comes out and we can move around, we’ll go together.

“To the cabin?” Carmen asked.

Elena denied it.

He pressed his finger on the cross marked in red.

The mine entrance.

—No. First we’ll go for the truth.

The stove crackled.

Ivan gritted his teeth to keep from screaming as Carmen splinted his leg.

Ramiro sat in a corner, defeated by years of silence.

Tomás looked at his son and then at Elena, as if he had just understood that this widow, whom they had taken for a crazy person, had been the only person in all of Valdemora who had been preparing for something real for months.

And outside, while the worst winter in decades buried the town under tons of snow, inside that secret refuge something much stronger than fear was born.

The decision to unearth a truth that had been waiting in the dark for years.
