The Locked Door in the Attic

The Locked Door in the Attic

Maya Chen had been in the house for exactly six hours and forty-three minutes when she decided the attic was lying to her.

Not in any way that mattered to the real estate agent, of course. The agent had chirped about "charming original features" and "a touch of vintage character," which was the same way grown-ups said *this place is haunted and we are not responsible*. The wallpaper in the upstairs hallway was peeling in long, sad curls. The kitchen smelled like a previous owner's life choices. And the stairs to the attic — narrow, steep, carpeted in something the color of old mustard — made a sound like a small animal clearing its throat every time you stepped on them.

But Maya wasn't thinking about the wallpaper or the kitchen. She was thinking about the door at the top of the attic stairs.

There were two doors. The first one opened onto a triangular crawl space full of cardboard boxes labeled in her grandmother's slanted handwriting: *Christmas Ornaments (FRAGILE)*, *Grandfather's Pipes (DO NOT OPEN — ASK MOM)*, *Photos — Unsorted*. The second one, set into the slanted wall at the back of the attic, was different. It was painted the same off-white as the surrounding wall. It had no knob — just a small, circular hole where a knob should have been, like a face missing an eye. And the wood around the hole was darker, as if a hand had been reaching for it over and over for years.

Maya had a habit, which her old friends back in Portland would have confirmed without hesitation, of being precisely the kind of person who would put her eye up to a hole in a door. She did not think of herself as a rule-breaker. She thought of herself as a *question-asker*. There was a difference. Rules said *don't*. Questions said *why not, and what's behind it, and what would happen if I—*

She pressed her eye to the hole.

It was dark. Then her eyes adjusted, and it was not dark. It was the soft, blue-green glow of a screen on standby.

Maya pulled back so fast that she knocked her shoulder into a cardboard box. *Photos — Unsorted* tumbled to the floor in a soft avalanche of dust and memory. She didn't pick it up. She was staring at the door.

A door with no knob, in a house that belonged to her grandmother, who had died three months ago. Her grandmother, who had never in fifteen years of Maya's life mentioned an attic, a blue-green light, or a second door.

Maya's mother, somewhere downstairs, was on the phone with an insurance company. Maya could hear her voice rising and falling in the patient, exhausted rhythm of a person who has been in charge of things for too long. Maya's father had died when she was nine. Her grandmother had been the second adult in her life who knew how to listen. Now she was gone, and her house — her secret, lying, beautiful house — was Maya's inheritance.

Maya thought: *I'm going to open that door.*

Then she thought: *I don't have anything to open it with.*

Then she thought: *What if I don't need anything to open it with?*

She put her eye back to the hole. The blue-green light pulsed, very slightly, as if breathing.

She was still standing there five minutes later, when her phone buzzed in her back pocket. A notification from a chat app she had only just installed that morning, on the long drive from Portland to this nowhere town. The app was called BioBuilder, and it had been recommended by a stranger on a forum about DNA — or, more accurately, by a stranger who had called DNA a "text file written in a four-letter alphabet," which had made Maya laugh for the first time since the moving truck pulled out of her old driveway.

The notification read:

> Welcome to BioBuilder, Maya! You haven't introduced yourself yet. Tell the community what got you curious.

Maya looked at the door. She looked at her phone. She looked at the door.

She typed, very slowly, with one thumb: *Hi. I just moved into my grandmother's house. There's a door in the attic that doesn't have a knob and something behind it is glowing.*

She hit send. She immediately felt foolish.

Then three dots appeared, almost instantly, as if someone had been waiting for her.

> DrChenLab: Hello, Maya. I think I know whose house you're in. Are you sitting down? You're going to want to be sitting down.

The Box That Wasn't a Box

It took Maya another hour to find the right box. She didn't go back to the door right away. She couldn't. Her hands were shaking in a way she didn't like, and her mother was still on the phone, and the house was so quiet that the sound of her own breathing felt rude.

So she did what she always did when she was nervous: she organized. She went through *Photos — Unsorted* carefully, sliding the prints into the empty box from *Grandfather's Pipes (DO NOT OPEN — ASK MOM)*. There were pictures of her mother as a child, of her grandmother as a young woman with a haircut that should not have worked but somehow did, and of a man Maya didn't recognize — tall, smiling, holding up a small glass vial in one hand and a notebook in the other. The vial was glowing faintly.

Maya stared at the photo for a long time.

Then she opened *Christmas Ornaments (FRAGILE)*. It was not, as it turned out, full of Christmas ornaments. It was full of notebooks. Fifteen of them, exactly, each one bound in a different color, each one labeled in her grandmother's slanted hand: *Volume 1: Beginnings*, *Volume 2: Reading*, *Volume 3: Writing*, and so on, up to *Volume 15: ?*. The last one had a question mark instead of a title, and the question mark had been drawn with a slightly unsteady hand, as if her grandmother had wondered about it too.

Maya pulled out *Volume 1: Beginnings* and opened it on the floor of the attic, cross-legged, with the door to the secret room at her back and the light from a single bare bulb casting long shadows across the pages.

The first page read, in handwriting that was young and certain:

> *If you're reading this, I'm gone, and you've found my room. Good. I was hoping you would. I was hoping it would be you.* > > *My name is Lin Chen. I am your grandmother. I was also, for forty years, a synthetic biologist.* > > *You are about to read the first of fifteen notebooks. They are not in any particular order except the order in which I learned things, and the order in which I want you to learn them. I have tried to write them the way I wish someone had written them for me, when I was your age and full of questions I didn't know how to ask.* > > *Before you read further, go into the room. The door will open. It knows your hand. I'll explain that in a moment, because it requires a short lesson in biology.* > > *For now: the room is not a room. It is a small laboratory, the kind I used to dream about when I was a girl. I have left you my journals, my equipment, my bacteria, and one rather large problem I could not solve. I am leaving them to you because I think you are the only person in our family stubborn enough to try.* > > *Welcome to the quest, my dear.* > > *— Grandma Lin* > > *P.S. The note on the bench is from a friend. Please watch the video before you do anything else.*

Maya's hands were still shaking, but in a different way now. She read the letter three times. Then she turned around and looked at the door.

It was still there. Still missing a knob. Still glowing faintly around the edges, as if the wood itself was embarrassed to be hiding.

She stood up. She walked to the door. She put her hand on the wood, flat, in the place where a knob would have been.

The door clicked — a soft, mechanical sound, like the closing of a small book — and swung inward on hinges that made no sound at all.

Maya stepped inside.

The room was small, maybe ten feet by twelve, with a slanted ceiling that followed the line of the roof. It smelled faintly of something clean and chemical, like a swimming pool in winter. There was a long bench against one wall, covered in glassware, notebooks, and a microscope that looked o
