The house smelled the same.
That was the first thing, and it nearly undid her. Thirty years, and the entryway still smelled exactly the same: of old-wall dampness, of the furniture wax, of something sweet that Marta had never been able to name and that was, simply, the smell of her mother.
She had come back to help empty it.
Her mother was moving to a smaller apartment, more comfortable, closer to everything. The house was being sold. Forty years had to be packed into boxes, decisions made about what to keep and what to throw away, and fond arguments had to be had about dishes no one had used since a wedding in the seventies.
Marta had a good memory.
She always had. It was almost a point of pride. She remembered the crack in the bathroom ceiling shaped like a river. The third stair that creaked. The pattern of the kitchen tiles, which she had counted so many times as a child that she still knew exactly how many there were. People would recount episodes from their own lives and she would correct them, and she was almost always right.
So when they moved the wardrobe, she didn't understand.
It was the wardrobe from her old room. A huge piece of furniture, in oak, that had been there since before she was born. The two of them pulled it away from the wall, panting, to wrap it in blankets.
And behind it there was a door.
Small. White. At a child's height. With a simple latch, the kind you open with two fingers.
Marta stood staring at it.
She had slept in that room until she was eighteen. The wardrobe had always been pressed against that wall. She would have seen it. A thousand times. Ten thousand times. A door doesn't hide itself for an entire childhood.
There was no door.
There had never been a door.
—That was always there —her mother said.
She said it from the hallway, without coming closer, without alarm, in the easy voice of someone commenting on the weather.
—Mamá, there was no door here.
—Of course there was. —Her mother kept wrapping a plate in newspaper, without looking up. —That's where you used to play. You'd spend hours in there, don't you remember? Writing on the wall with your pencil. There was no getting you out.
She said it tenderly.
Like a fond memory.
Marta let out a laugh that didn't come out right.
Her mother shrugged and went back to her plates, without insisting, without defending herself. She wasn't lying. She wasn't arguing. She simply remembered a different childhood from Marta's, one in which there was a door, and a little room, and a happy girl who wrote on walls.
Marta knelt down.
She pushed the latch open with two fingers.
And she opened it.
Inside, the air was dry and old, the air of many years sealed away, and it touched her face like a breath.
It was a small room.
No windows.
About the size of a built-in closet, perhaps a bit larger. Bare walls, bare floor. There was nothing.
Nothing except the writing.
All four walls, as far as the little light coming through the door reached, were covered in words written in pencil. Hundreds of times. Thousands. Two words, repeated until they filled every centimeter.
DON'T OPEN.
DON'T OPEN.
DON'T OPEN.
Marta entered on her hands and knees, because she couldn't stand upright, and followed the lines with her eyes.
Up near the ceiling, the letters were large, round, careful. The handwriting of a girl who is making an effort, who respects the line even when there is no line.
Further down they became quick. Crooked. The same hand, but in a hurry, as if writing slowly was no longer enough.
At the baseboard, in the corners, the last ones were made by a hand so small and so rushed they could barely be read. Nervous marks, cramped, layered one over another.
And all of them, every one, was her handwriting.
Not similar.
Hers.
That odd way of closing the letter A, the one her teacher had tried without success to correct. The R that always came out lopsided. It was her hand. The one from then and the one from now. She recognized it the way you recognize your own face in an old photograph.
Without realizing it, she did what she used to do as a child when she was frightened.
She put the pencil in her mouth.
And only then, with the soft wood between her teeth, did it occur to her.
She didn't remember having brought a pencil.
Marta went very still, on her hands and knees, in that airless room.
And she began to understand.
Because at first she had read it the way anyone would. A frightened girl writing to herself. A strange game played by a lonely child. The easy question, the one that almost brought tenderness: what kind of child writes that, to herself, a thousand times?
But the warning wasn't in the past.
It didn't say "I didn't open." It didn't say "don't you open it, you who will come to play later."
It said DON'T OPEN. Now. Imperative. Directed at someone who would be standing, or on her hands and knees, in front of the wall, with a hand on a latch.
Directed at an adult woman.
At her.
The girl wasn't playing. The girl knew. She knew that one day, many years later, she would come back transformed into something else, into someone grown who would no longer remember her, and that this someone would find the door and open it. And she had spent hours. Hundreds of hours. Thousands of repetitions, until her fingers gave out, trying to reach across all those years to stop this exact moment.
This one.
The one happening now.
And she had already opened it.
She was inside. Reading the warning. Too late.
It was then that she saw it.
Down near the floor, among the hundreds of strokes faded by time, there was a different line.
Darker.
Fresh.
The graphite still gleamed a little, the way pencil looks when it's been written recently, days ago, weeks at most.
And this was not a child's handwriting.
It was adult handwriting.
Firm. Large. With the odd A and the lopsided R, but the steadiness of an adult hand.
It was her handwriting from today.
DON'T OPEN.
Marta didn't remember having written it.
She backed out, not standing, scraping her knees, not daring to turn her back on the wall.
In the kitchen, her mother was humming.
—Did you find anything good in there? —she asked, without turning around.
Marta didn't answer.
She picked up her bag. She said she'd lost track of time, that she'd come back another day to continue with the boxes. Her mother kissed her and told her to drive carefully, as she always did, as if nothing at all had just happened.
She drove the two hours back without turning on the radio.
And along the way she told herself things.
That her mother was getting old. That old people's memories invent things, fill in gaps, soften edges. That as a child one forgets entire rooms, entire houses. That the fresh graphite was nothing, a trick of the light, a smudge. That she had a good memory, the best, and if she didn't remember that room it was simply because it hadn't been important.
By the time she arrived home, she almost believed it.
Almost.
A few days passed.
Her apartment. Her life. Her things in their places. Her name, Marta, on the mailbox, on the bills, on the mug someone had given her that she used every morning.
She was in the kitchen, making the shopping list. Milk. Bread. Something for dinner. A pencil in her hand, a piece of paper stuck to the fridge.
She glanced up for a moment toward the window.
When she looked back down, her hand had carried on by itself.
Below the milk and the bread, in round, careful, deliberate letters, a girl's handwriting making an effort, the paper said:
DON'T OPEN.
DON'T OPEN.
DON'T OPEN.
Marta didn't remember having written that.
She didn't remember lowering the pencil.
And then, slowly, the way cold water rises up your legs, she understood about the fresh line.
The one in adult handwriting, down on the wall, near the floor.
She had written it herself.
Not as a child.
Recently. Weeks ago. On a visit to that house that she was no longer able to remember having made.
She had been inside the room before, already as an adult. She had read the warning. She had added to it one more time, with her adult hand. And she had left. And she had forgotten everything, the door, the room, the entire trip, the way she couldn't remember right now having written on the paper on the fridge.
Each return erased the one before it.
The wall was the only thing keeping count.
The only thing that knew how many times she had already entered that room, and come back out with a little less of herself.
She looked at the paper on the fridge.
She looked at her own hand, which was still holding the pencil, and which seemed to her, for an instant, smaller than it should be.
She tried to let go of the pencil.
Her hand didn't let go of the pencil.
And Marta, standing in her kitchen, two hours from her mother's house, knew she was already on her way. That she would go back. That she always went back. That somewhere in that wall there was still a small empty space, low to the ground, at floor level.
And that the space was waiting for her for one more line.
