"Did you hear it again?"

I did not look up from the table. The wood was cold. My hands were shaking. I poured the tea. The water was still hot. It hissed. A small sound. Like a sigh.

"Yes," I said.

My brother, Thomas, sat across from me. He was pale. His eyes were wide. He looked at the wall. I looked at my cup.

"Where?" I asked.

"Inside," he whispered. "In the walls."

I laughed. It was a dry sound. No humor in it. "It is the house, Thomas. It is old. The pipes. The wood."

"No." His voice was sharp. "It is not the pipes. It is knocking. Three times. Always three."

I drank the tea. It burned my tongue. I did not care. I needed the heat. I needed something solid.

"Go to bed," I said. "You are tired. You have been walking all day."

He did not move. He stared at me. There was fear in his face. A raw, ugly fear. I hated it. It made me angry. I wanted to strike him. I wanted to make it stop.

"Thomas," I said. My voice was low. "Stop it."

"What if it is real?" he asked.

I put the cup down. The ceramic clinked against the saucer. A sharp, final sound.

"Nothing is real here but us," I said. "We are alone. The world is gone. Or changed. Or dead. We do not know. But we are here. That is all that matters."

He nodded. Slowly. He stood up. His knees cracked. He walked to the door. He did not look back.

The door closed. The latch clicked. A small, metal sound.

I sat alone. The room was dim. The candles were low. Shadows stretched across the floor. They looked like fingers. Reaching for me.

I looked at my hands. They were trembling. I flexed my fingers. They were stiff. The joints ached. I was forty years old. My hands looked like an old man’s hands. They were the hands of a woman who had scrubbed floors. Who had buried children. Who had watched her country burn.

I thought of the war. It was years ago. Ten years. Maybe more. Time was strange now. We had no clocks. We had no newspapers. We had no one to tell us the year. We lived in the present. A long, gray present.

I had come to this house because it was empty. It was on the edge of the town. The town was a skeleton. The shops were boarded up. The streets were silent. We were the last ones. Or so we thought.

Thomas had followed me. He always followed me. He was younger. Three years younger. He was strong. But his mind was weak. It broke under the weight of the silence.

I tried to ignore the knocking. I focused on my hands. I massaged the knuckles. The pain was good. It was real. I needed the pain. It kept the other things away. The whispering. The scratching.

The scratching came again.

It was not loud. It was soft. Like a mouse in the plaster. But it was rhythmic. Tap. Tap. Tap.

I closed my eyes. I breathed in. I breathed out.

"It is the wind," I whispered to myself.

I opened my eyes. The room was still. The shadows were still.

I went to the window. I pulled the curtain aside. The night was dark. There were no stars. The sky was a black blanket. It covered everything. It smothered the earth.

I saw a light in the distance. A small, yellow dot. It was far away. Maybe a mile. Maybe two.

Who was there?

I gripped the curtain. The fabric was rough. It tore my skin. I did not feel it.

I needed to see. I needed to know if I was alone.

I put on my coat. It was heavy. Wool. It smelled of dust and mothballs. I put on my boots. They were wet. I did not care.

I walked to the door. I opened it. The cold hit me. It was a physical blow. It bit into my cheeks. It froze my breath.

I stepped out. The air was still. There was no wind. The trees were black shapes. They stood like sentinels. They watched me.

I walked toward the light. My boots crunched on the gravel. Each step was loud. Too loud. I felt exposed. I felt small.

The light grew larger. It was a window. A house. It was not far. It was closer than I thought.

I stopped. I looked at the house. It was old. Like mine. The paint was peeling. The windows were dark, except for one. The one with the light.

Who lived there?

I knocked on the door.

Knock. Knock. Knock.

No answer.

I knocked again. Harder.

Knock. Knock. Knock.

The door opened. A man stood there. He was tall. He wore a gray coat. His face was hidden in the shadows.

"Who are you?" I asked.

He did not speak. He stepped aside.

I hesitated. I should go back. This was not safe. This was a trap.

But I stepped inside.

The room was warm. A fire burned in the hearth. It crackled. It popped. The light was orange. It was soft.

The man turned. He was old. His face was lined. His eyes were blue. They were kind. But they were sad.

"Sit," he said. His voice was rough.

I sat. I did not take off my coat. I kept my guard up.

"You followed the sound," he said.

"I heard knocking," I said. "In my house."

He nodded. "It is not in the house. It is in you."

I looked at him. "What do you mean?"

He pointed to my hand. It was resting on my knee. It was trembling.

"You are afraid," he said. "The fear makes the sound. The sound makes the fear. It is a circle."

"I am not afraid," I said. My voice was hard. "I am brave. I survived the war. I survived the famine. I am not afraid of a ghost."

The man smiled. It was a sad smile. "We are all ghosts, my dear. We are just the ones who remember how to walk."

He poured me tea. It was the same tea. Same color. Same smell.

"Drink," he said.

I drank. It was hot. It burned me.

"Who are you?" I asked.

"My name is Elias," he said. "I live here. Alone."

"Alone?"

"Yes. The others are gone. Like everyone else."

I thought of Thomas. He was in my house. He was waiting. He was afraid.

"I have a brother," I said. "He is... unwell. He hears things."

Elias nodded. "We all hear things. When the world goes quiet, the mind fills the space. With noise. With fear. With ghosts."

"How do I stop it?" I asked.

"You cannot stop it," he said. "You can only understand it. The knocking is not an attack. It is a cry. It is the part of you that is dying. It wants to be heard."

I looked at my hands. The trembling had stopped. My heart was beating. Thump. Thump. Thump.

It matched the knocking.

I thought of Thomas. I had always protected him. I had pushed him away. I had told him to be quiet. I had told him to be strong.

I had been wrong.

I had been cruel.

The realization hit me. It was a physical pain. A twist in the gut.

I stood up. "Thank you," I said.

I walked to the door. I opened it. The cold rushed in.

I walked back to my house. The gravel crunched under my feet. It sounded like bones breaking.

I reached my door. I opened it.

Thomas was sitting at the table. He was not moving. He was staring at the wall.

"Thomas," I said.

He turned. His eyes were red. He had been crying.

"I heard it," he said. "It was in my head. I tried to fight it. I tried to break it. But it was me. It was my own heart."

I walked to him. I sat down. I took his hands. They were cold.

"I am sorry," I said.

He looked at me. Confusion in his eyes.

"For what?" he asked.

"For being afraid," I said. "For telling you to stop. For pretending it wasn't real."

He squeezed my hands. His grip was tight.

"It is real," he said.

"Yes," I said. "It is real. But it is not a monster. It is us. It is our pain. It is our life."

The knocking started again. Tap. Tap. Tap.

It was louder. It was faster. It was inside the walls. It was inside the floor. It was inside my chest.

I did not try to stop it. I let it happen. I let it beat.

I looked at Thomas. I saw myself in his face. The fear. The loss. The love.

We were not alone. We were together. In the noise. In the silence.

The light from the candles flickered. The shadows danced.

I held Thomas’s hands. I held on.

The knocking continued. It was the sound of us, still alive. Still here. Still breathing.

I closed my eyes. I listened.

It was not a threat. It was a song.

A song of endurance.

I wept. The tears were hot. They fell on my hands. They fell on Thomas’s hands.

We sat there. In the dark. In the quiet. In the noise.

We were not saved. We were not free.

But we were together.

And that was enough.

The morning came. The light was gray. The sun was hidden.

I made breakfast. Porridge. It was thin. It tasted of water.

Thomas ate. He did not speak. I did not speak.

We ate in silence.

When we were done, I washed the bowls. The water was cold.

I looked at my hands. They were still. The tremor was gone.

Or maybe it was just slower.

I dried my hands. I put on my coat.

I went to the door. I opened it.

The town was quiet. The streets were empty.

I walked out. I walked toward the light in the distance.

I did not know who I was. I did not know what was real.

But I knew the sound.

I knew the rhythm.

I walked on.

The knocking followed me.

It was in my feet.

It was in my heart.

It was in the air.

I was the machine.

I was the noise.

I was alive.
