The window hung in the air, waiting for you to approach. There was no wall around it. No house. No frame of stone or brick. Only a window suspended in the darkness of the abandoned courtyard, its wooden frame weathered gray, its glass reflecting a sky that did not exist.
You stopped ten paces away. The rain had ended nearly an hour ago, yet drops continued to fall from the window's sill. They struck the ground one by one. Plink. Plink. Plink. Each drop disappeared before touching the mud.
You had come to this place because of a letter. A letter written in your sister's handwriting. A letter that should not have existed. She had been missing for eleven years. The police had eventually closed the case. Your mother had stopped speaking about her. Your father had destroyed every photograph in which she appeared, except one.
And three days ago, that photograph had arrived beneath your apartment door.
On its back were seven words:
COME TO THE OLD MILL AT MIDNIGHT. COME ALONE.
You had almost burned it. Instead, you came.
Now you stood before the impossible window. You could see your reflection in the glass. But there was something wrong with it.
Your reflection was not looking at you.
It was looking over your shoulder.
Slowly, you turned.
Nothing.
The courtyard was empty. The old mill stood behind you, black against the moonless sky. Its windows were broken, its roof partially collapsed. The weeds had swallowed the path that once led to the entrance.
You looked back at the window.
Your reflection was still staring behind you.
Then it raised one finger to its lips.
You stepped backward.
The reflection smiled.
You did not.
A soft tapping came from the glass.
Three taps.
You remembered something your sister used to tell you when you were children.
Never answer a knock after midnight.
You had laughed at her then.
She had not.
Another three taps.
You approached the window. The glass was cold enough to burn your fingertips.
“Are you there?” you whispered.
Your reflection shook its head.
Then it mouthed a word.
Run.
The courtyard lights came on.
All of them.
You had not noticed lights before. There were four iron lamps surrounding the mill, each one glowing with a weak yellow flame.
And beneath the nearest lamp stood a man.
He was wearing a dark suit. His face was turned away.
You took a step toward him.
He raised one hand.
Not waving.
Pointing.
At the window.
You turned.
Your reflection had disappeared.
The glass now showed a room.
A small room with yellow wallpaper and a wooden desk.
Your sister was sitting at the desk.
She looked exactly as she had the last time you saw her.
Twenty-two years old. Long dark hair. A small scar above her left eyebrow.
She was writing something.
You pressed both hands against the glass.
“Mara!”
She looked up.
Her eyes widened.
She stood so quickly that the chair fell backward.
She ran toward the window.
You expected her to crash into the glass.
Instead, she stopped on the other side.
Her palm met yours.
The surface between you was impossibly thin.
Her eyes filled with tears.
“You shouldn't have come,” she said.
Her voice sounded distant, as though traveling through a long tunnel.
“You sent the letter.”
She shook her head.
“No.”
“You sent me the photograph.”
“No.”
“Then who did?”
She glanced toward the doorway behind her.
Fear crossed her face.
“Listen carefully.”
You nodded.
“There are two rules.”
Her voice dropped to a whisper.
“First, don't open the window.”
You looked at the frame.
“What is the second?”
Mara swallowed.
“Don't believe anyone who tells you they are me.”
You stared at her.
“That doesn't make sense.”
“It will.”
Behind her, the door to the yellow room began to open.
Mara looked over her shoulder.
Her expression changed.
She grabbed a piece of paper from the desk and held it against the glass.
Written across it were four words:
THE MILL HAS NO BASEMENT.
You frowned.
Everyone in town knew the old mill had a basement.
Your father had taken you there once.
You remembered the stairs. You remembered the rusted machinery. You remembered Mara hiding behind a support beam while your father searched for her.
But there was something else.
Something you had forgotten.
You remembered your father telling you never to go downstairs.
Not because it was dangerous.
Because, he had said, “There is nothing down there.”
Mara tapped the paper.
Then she pointed toward the mill.
You turned.
The suited man was gone.
The nearest lamp flickered.
Once.
Twice.
Then darkness.
You heard footsteps behind you.
You spun around.
The man stood only a few feet away.
His face was pale and strangely familiar.
For several seconds you couldn't understand why.
Then you recognized him.
Your father.
Older than you remembered.
Much older.
His hair was white, his face lined, but there was no mistaking him.
You stepped backward.
“Dad?”
He smiled.
“You shouldn't have come.”
You looked at the window.
Mara was pounding against the glass.
“Don't listen to him!”
Your father raised an eyebrow.
“She always was good at lying.”
Mara screamed something you couldn't hear.
Your father stepped closer.
“I've been looking for you for eleven years.”
“You're dead.”
His smile disappeared.
“That's what they told you.”
“Who?”
He glanced toward the window.
“The people who built it.”
You looked between them.
“What is this place?”
Neither answered.
Your father reached inside his coat.
You tensed.
He removed an old brass key.
You recognized it immediately.
It had belonged to Mara.
She had worn it around her neck when you were children.
Your father held it out.
“She left this behind.”
Mara shook her head violently.
“No.”
Your father frowned.
“You see?”
He looked at you.
“She wants you to believe she has been trapped in there all these years.”
“Hasn't she?”
“No.”
He took another step.
“The person behind that glass isn't your sister.”
Mara's face went white.
Your father whispered:
“She is what your sister became.”
The words seemed to drain the warmth from the courtyard.
“What does that mean?”
“Your sister disappeared because she discovered the window.”
He looked at the glass.
“She thought it showed another world.”
Mara pressed her hand against the window.
Your father continued.
“It doesn't.”
The glass rippled.
Like water.
“She discovered something much worse.”
You stared at him.
“What?”
He looked directly into your eyes.
“It shows the moments that were removed from our lives.”
You felt a chill.
“What moments?”
“The ones someone wanted us to forget.”
The window suddenly brightened.
The yellow room vanished.
In its place appeared a scene from your childhood.
You were eight years old.
Mara was twelve.
Your father stood between you.
And beside him was a woman.
Your mother.
But she was crying.
You watched the memory unfold.
Your father was holding the brass key.
Your mother was begging him not to open the window.
Mara was shouting.
You were standing silently beside them.
Then your younger self turned toward the window.
And smiled.
You recoiled.
“I don't remember this.”
“You weren't supposed to.”
The image changed.
You saw your father open the window.
Your mother screamed.
Mara grabbed your hand.
Something moved behind the glass.
Something tall.
Something wearing your face.
Then the memory ended.
You looked at your father.
“What happened?”
He looked exhausted.
“You opened it.”
“No.”
“You did.”
“I was eight.”
“Yes.”
“Why would I do that?”
He didn't answer.
Mara did.
Because suddenly she was no longer frightened.
She was crying.
“You asked it to take you away.”
Your throat tightened.
“Why?”
“Because you had already seen what was in the basement.”
You stared at her.
The old mill seemed to shift behind you.
A door creaked open somewhere inside.
Your father closed his eyes.
“We thought you had forgotten.”
“What was in the basement?”
He looked at Mara.
She nodded.
Then your father said:
“Your mother.”
Silence.
You shook your head.
“She died.”
“No,” Mara said.
“She never died.”
Your father looked at the window.
“She went down there eleven years before Mara disappeared.”
A realization began to form.
The missing people. The strange photographs. The impossible window. The forgotten memories. The letters. The basement that supposedly did not exist.
All of them connected.
You turned toward the mill.
For the first time, you noticed something you had overlooked.
A thin line in the earth.
A rectangular outline beneath the weeds.
A trapdoor.
Your father grabbed your arm.
“Don't.”
You pulled away.
“Why?”
“Because if you go down there, you will remember everything.”
You looked at the window.
Mara was no longer there.
The yellow room was empty.
Then, from behind the glass, someone else appeared.
Your mother.
She looked exactly as she had the night she disappeared.
She placed both hands against the window.
And smiled.
Not sadly.
Not lovingly.
Almost triumphantly.
Her lips moved.
You could not hear her words.
But you could read them.
You left me here.
The window cracked.
A thin line spread across the glass.
Then another.
Then dozens.
Your father stepped backward.
“No.”
The crack formed a perfect circle.
Inside it, darkness began to leak through.
And from somewhere beneath the old mill came a sound you had heard only once before.
On the night your sister disappeared.
Three knocks.
From below.
Your father whispered the truth at last.
“The window isn't a door.”
You stared at him.
“Then what is it?”
He looked toward the trapdoor in the earth.
“A witness.”
Another crack split the glass.
Your mother's smile widened.
And suddenly you remembered.
You remembered opening the window.
You remembered what came through.
You remembered why you had asked it to take you away.
And most horrifying of all—
you remembered that you had never been eight years old.
Not really.
The child in the memories had your face.
Your voice.
Your memories.
But it had never been human.
You looked at your father.
He was crying now.
“I'm sorry,” he said.
Behind him, the trapdoor began to open.
Something climbed out.
It was small.
Barefoot.
Eight years old.
And wearing your face.
It looked at you.
Then it smiled.
“It's your turn,” it said.
The impossible window shattered.
Every piece of glass fell upward.
And for the first time, you understood why it had been waiting for you.
It had not been showing you the past.
It had been waiting to show you who you were.
