The iron gate did not rust. That was the first thing I noticed, and the last thing I wanted to see. It stood at the edge of the fog, a jagged tooth in the jaw of the night, holding the line between the living and the waiting. I held the key in my palm. It was warm. It had been warm for three days. I had stopped sleeping. Sleep was a luxury for those who did not hear the breathing in the walls.

Thomas sat by the hearth. He did not look up. He was polishing a silver spoon. The sound was a dry rasp, like a mouse dragging itself across floorboards.

It is cold, I said.

The fire is out, Thomas said.

Then why do you polish the spoon?

Because the silver tarnishes in the dark. He turned the spoon. The metal was dull. It was not silver. It was lead. I knew it. We both knew it. But the lie was the only thing keeping the roof from collapsing.

You are lying to me, I said.

I am lying to myself, Thomas corrected. There is a difference.

I walked to the window. The glass was thick, clouded with the breath of the house. Outside, the garden was a black void. The roses were gone. They had withered in the summer, turned to black lace, then to dust. Only the thorns remained. They stood like the ribs of a beast picked clean by time. I pressed my forehead against the cold pane. My breath fogged the glass. I watched my own face. It looked old. The eyes were hollow. The skin was tight over the bones. I looked like a man who had been buried alive for a century and had just remembered how to breathe.

We have to leave, I said.

Thomas stopped polishing. The spoon clattered into the bowl. The sound was too loud. It echoed in the empty hall. The dust motes danced in the air, suspended in the grey light.

Leaving is not an option, Thomas said.

Why?

Because the gate is closed.

I have the key.

The key is not a key. It is a promise. And promises are heavy. They do not open doors. They hold them shut.

I turned back to him. He was small. He had always been small. He sat in the high-backed chair, his legs not reaching the floor. He was my friend. He was the only person who had not looked at me with fear. Or pity. Or hunger. He had looked at me with recognition. He knew what I was. He knew what I had done. Or what I would do.

What did I do? I asked.

You are here, Thomas said. That is enough.

I wanted to shout. I wanted to break the window. I wanted to tear the skin from my face. But I was calm. A deep, terrible calm had settled into my bones. It was the calm of the deep ocean, where the pressure crushes all thought. I felt it in my teeth. I felt it in the soles of my feet.

Thomas, I said. Tell me the truth.

He looked at me. His eyes were wet. They were not crying. They were just wet. Like the air before a storm.

The truth is that you are not the first to hold that key, he said.

I shook my head. No. I am the first.

No. You are the ninth.

The number hung in the air. Nine. I counted the steps I had taken since entering the house. One. Two. Three. Four. Five. Six. Seven. Eight. Nine. I was standing on the ninth step of the staircase. The spiral staircase that led to the attic. The attic where the air was thin and the shadows were long.

Who were they? I asked.

They were like you. Good men. Men who loved. Men who wanted to save. They came to the gate. They held the key. They believed they could open it. They believed they could walk through and change the world.

And what happened?

They opened the gate.

And?

And they found nothing. No world. No change. Only the same fog. The same garden. The same house. They walked out, and the gate closed behind them. And they came back.

I felt a chill. It was not from the cold. It was from the knowledge. It was a physical blow. I gripped the edge of the table. The wood bit into my fingers.

You are saying I am trapped, I said.

I am saying you are bound, Thomas said. By love. By duty. By the promise you made to the dead.

I made no promise.

You did. To her.

Her. I did not know the name. I had forgotten it. Names are the first things to go. They slip away like water through fingers. I tried to grasp it. I reached into the dark of my mind. I felt the shape of it. A mouth. A smile. A hand reaching out.

I remember, I whispered.

No, you do not, Thomas said. You remember the feeling. Not the fact. That is the curse. You remember the weight. Not the cause.

I looked at the key. It was still in my hand. It was getting heavier. It was burning my palm. The metal was hot, then cold, then hot again. It was pulsing. Like a heart.

I will not go back, I said. I will not walk through the gate. I will break it.

Thomas smiled. It was a sad smile. A tired smile.

You cannot break it, Thomas said. It is not made of iron. It is made of memory. You can only break your own mind.

I dropped the key. It hit the floor with a ring that lasted for eternity. It lay there, gleaming in the dust. I stared at it. It was just a piece of metal. Cold. Dead. Useless.

I am tired, I said.

I know, Thomas said.

I will not fight it anymore.

Thomas nodded. He reached into his pocket. He pulled out a small vial. It was glass. It was empty.

Drink, he said.

I looked at the vial. I looked at Thomas. I did not trust him. I had never trusted him. But I was so tired. The effort of resistance was too great. The walls were closing in. The fog was outside, and it was inside. It was in my lungs. It was in my blood.

I took the vial. I uncorked it. There was nothing in it. No liquid. No poison. No mercy. Just air.

I drank the air. I swallowed the emptiness.

And then I felt it. The release. The letting go. It was not a death. It was a surrender. The knot in my chest untied. The weight on my shoulders lifted. I was not a prisoner. I was a guest. And the host had finally shown me the way out.

The way out was in.

I looked at the gate. It was no longer a barrier. It was a mirror. I saw my own face in it. Not the old face. Not the hollow face. The young face. The face of the man who had first held the key. He was smiling. He was happy. He did not know what was coming. He did not know the pain. He did not know the repetition.

I walked to the gate. My feet did not touch the floor. I floated. The fog parted. It was not white. It was black. It was the black of the universe. The black before the first light.

I passed through the gate.

I expected to fall. I expected to wake up in the garden. In the black roses. In the dust.

I did not fall. I did not wake up. I was still there. I was still holding the key. But the key was gone. My hand was empty.

Thomas was still by the hearth. He was polishing the spoon. The sound was the same. The dry rasp. The mouse in the wall.

It is cold, I said.

The fire is out, Thomas said.

Then why do you polish the spoon?

Because the silver tarnishes in the dark.

I looked at the gate. It was rusted. It was old. It was falling apart. The iron was flaking. The paint was peeling. It was not a boundary. It was a wound. It had been there for a long time. It would be there for a long time.

I sat down. I sat in the chair opposite Thomas. I did not speak. I did not move. I listened to the breathing in the walls. I listened to the scratch of the spoon. I listened to the silence.

The cycle was not a circle. It was a spiral. It was tightening. It was getting smaller. It was getting tighter.

But I was not afraid.

I was ready.

I was waiting.

The fog came in. It covered the floor. It covered the table. It covered Thomas. It covered me.

I closed my eyes.

I opened them.

I was holding the key.

It was warm.
