Mara's ceiling warmed before the sun did. Heat rose from the bakery downstairs in buttery sighs, as if the whole building were a croissant inflating. She lay there for a breath, hearing trays slide and thump, metal on metal, then swung her legs out of bed and into air that smelled faintly of cinnamon and yeast. There was a note on her kettle, in her own handwriting, reminding her to call the electric company. It was ordinary as a cloud, which was another way of saying it worried her only as much as the weather. She peeled the note off and stuck it to her laptop instead. The kettle clicked, a small, patient sound, and began to hum. Down in the street, a bus exhaled at the corner. Someone laughed the bright, sleep-starved laugh of a baker just off shift. In the hallway, under the mural of tulips painted by a tenant before Mara had moved in, something thudded against the mailboxes. She went to the door at the same moment the letter slid through the slot and kissed the floor. The envelope was thick, the paper good, her name hand-lettered like the start of a fairy tale: Ms. Mara Ada Finch. The return address was a law firm she didn't recognise. When she tore it open, a tin clattered out—an old cigar tin, corners dented, pale blue rubbed to silver along the edges. Inside, nestled in tissue that smelled faintly of cedar and old newspapers, was a brass key with a battered white tag. The tag said, simply, LATER. There was a card tucked under the key, the handwriting sharp and slanted. “For Mara,” it read. “Use carefully; later has sharp edges. —Sela” Aunt Sela, who wore silk caftans in winter and varnished her nails in the window so they'd catch the light, had been the family's argument with gravity. She had died in March with a laugh still in the room, like a ribbon someone forgot to pick up. The last time Mara visited her, the apartment smelled of orange peels and tea lights, and Sela made her a toast with honey and salt, insisting that some things needed both. Mara turned the key over in her palm. It wasn't large, just long enough to sit diagonally across her hand, warm from the tin already, its teeth notched like a skyline. “Later,” she said, and set it gently on the counter as if it might startle. The kettle sighed. She brewed the tea and drank half before the clock above the sink insisted she was late, and then she slid the key into her pocket without making a decision about it and hurried to the bus. At the café, an hour later, she made foam as soft as the inside of a seashell and coaxed espresso into curls for regulars who wanted to be seen precisely as tired as they felt. Her coworker Kiko was trying to teach a fern not to resent fluorescent light. Mr. Alvarez from 3B came in with paint on his knuckles and bought two cinnamon rolls. The violinist who played outside on Fridays came in just to stand by the pastry case and breathe. “You look like you brought a thought with you,” Kiko said, watching the cups stack and unstack under Mara's hands. “I got a thing from my aunt,” Mara said. “A key. It says ‘later.’” Kiko blinked, delighted. “A drama key! The kind of key that only opens something when the lighting is good.” “More like the kind you throw in a junk drawer,” Mara said, but she touched it through the denim anyway, feeling its weight prove itself. By closing, her hair smelled faintly like espresso grounds and sugar. The sky over their block was the particular grey of an unwashed spoon. She took home two end-of-day croissants, warm in a paper bag, and climbed the stairs past the tulips. In her kitchen—sink with a scar, stove that tilted by a whisper, a table rescued from a curb and made honest with sandpaper—she set the croissants down, turned on the lamp with the crooked shade, and placed the brass key on the table. She remembered Aunt Sela's hands. How they always seemed to be building something even when empty. She reached for the key, then set it down, then reached again. “All right,” she told the empty room. “Let's see what you are.” Her first thought was the front door. It had a proper keyhole for the deadbolt, old enough to mutter in winter. When she eased the brass teeth in, they slid as if the lock had been waiting. Click. Nothing dramatic happened. No trumpet of wind, no crack in the floor. There was only a soft tightening behind her ears, like the pause between inhaling and exhaling. She leaned toward the peephole out of habit. The hallway beyond was—ordinary. Tulips. The scuffed grey runner. Nobody there. Then, just as she was about to let her breath go, she heard the breath-on-wood sound of a knuckle meeting the door. Not from now but from later—like an echo that arrived before the sound. Three knocks, then a beat, then one: a patient rhythm. Her heart tried to both rise and sit at once. She kept her eye to the peephole. The air in the hallway seemed to pool and thicken, the way heat does before a summer storm. A shape gathered outside her door—not a ghost, not a blur, just a thinning of distance. She saw the idea of a bag of fruit in a hand, a paper bag dark at the bottom where juice had seeped. She saw Mr. Alvarez's hat. The sensation released. The hallway returned to a hallway. Mara let go of a laugh because it had nowhere else to go. She twisted the lock back. Later, she thought. Maybe the lock had shown her the next time it would be used. Her hand found the tin again. The key lay there like punctuation, waiting to end or save a sentence. Next: the kettle. She felt ridiculous pressing a key against a kettle, but the world had been ridiculous all day and had not fallen apart yet. She found a tiny seam where the handle met the body and turned the key there. The kettle answered by singing half a note of steam, a note she knew came right before a boil. She looked at the clock: 7:03. The kettle would boil at 7:04. She lifted it and found the water just about to flip into bubbles, tension shimmering on its surface like impatience. Not earth-shattering, but true. She turned the key in the hinge of her planner's ring. This time the click came with a spill of feeling, as if someone in the next room had whispered her name. The paper cool under her fingertips warmed. She thumbed to tomorrow. Her handwriting had already been there—hers and not hers: a slant she recognised, a pressure she didn't. Buy lemons. Call Dad. Leave early; the bus will be late. And, in a margin, boxed and underlined twice: 9:17 tonight—do not open the left-hand drawer. She stared at the line until the letters swam. She didn't keep secrets from herself in margins. She didn't underline. She didn't write warnings as if she were the kind of person who needed them. She flipped back to today. Her list was as spare as it had been that morning. Call electric company. Fold laundry. Eat something green. For a long moment she sat with both days open in front of her, feeling as if she had caught herself out of the corner of her eye. At 7:20, a knock came: three, pause, one. When she opened the door, Mr. Alvarez stood there, hat in hand, the paper bag darker where apricot juice had betrayed it. “My tree was generous,” he said. “Please rescue me from my own harvest.” She took the fruit and thanked him, feeling the hairs on her arms agree with the world that something had changed. After he left, she put two apricots on a plate and cut one open. The knife slid like the fruit had been thinking about being sliced all day and was relieved it could stop. She ate. It tasted like summer being precise. The key lay on the table as if it had always been part of it. She wanted to test it again, and not at all. She turned it idly in her fingers until her thumb found the smooth worn path of old handling. Who else had done this? Sela would have. Sela, who once brought Mara a paperweight full of dandelion seeds and said, “It's very important to know that some things are always blowing away and also absolutely trapped.” She tried the key in her phone where the charging cable went. She laughed at herself for it and did it anyway. The key was too wide and not truly meant for such a thing, and yet she felt the faintest consent through her fingertips, the way a card accepts a swipe. The screen flared, then settled. One new voicemail badge blinked and resolved into a transcription: Tomorrow, 10:10 a.m.: “It's me. Don't forget the lemons, and—” The voice tangled in static. Then: “Tonight, 9:17 p.m. Please don't open the left-hand drawer.” She froze, the prickling down her arms now a hum that lived in her ribs. It was her voice. Not exactly, but adjacent. The way you sound when you speak into a pillow or a winter scarf. Familiar and altered by weather. She checked the time. 8:03. She walked to the kitchenette. The left-hand drawer was nothing. It was takeout menus and rubber bands, a lighter that always chose not to work, a tape measure that pinched. The right-hand drawer held cutlery, which would have made for a more interesting curse. She rested her hand on the left-hand drawer's handle. The metal was cool. “I won't,” she said out loud, because it seemed like a promise needed to be made with breath to count. She needed to do something that would make the next hour pass without the hour clinging to her. She washed the plates. She called the electric company and waited on hold through three songs that were not as soothing as they wanted to be. She sorted the mail. She texted Kiko a picture of the apricots, and Kiko wrote back, “Summer's buttons.” She peeled a lemon very slowly and made tea again with the peel curled like a ribbon. At 8:49, the building hiccuped. The hallway lights flickered. The oven downstairs coughed, a deep metallic sound, then returned to its steady sigh. Rain started—the just-committed kind, fat drops pattering against the fire escape and the tulips that did not seem to know they were flowers painted on wood. Mara stood at the table with the key in her palm and tried to think of Sela's voice. It came like a scent. “Use carefully; later has sharp edges.” She turned the key in the tin again, wanting the comfort of the lid's drag and snap. She tried one more test—what couldn't possibly be a test: the strap on her old canvas bag. The key turned against the buckle, and she felt a tug as if the bag had shifted to make room for something not yet inside. When she looked, there was a lemon rolling against the seam, though she hadn't put one there. It was somehow worse when the magic stayed small. It made it fit into her ordinary life with no effort at all. 9:11. The rain picked up. Footsteps went by in the hall—running, then a laugh, then quiet. A bus gasped outside and moved on. Somewhere two floors down, a door thumped. She stood in the kitchen and watched the clock. Minutes go slower when you look at them directly. They apparently insist on their own pace when unobserved because 9:16 arrived in a rush, and she didn't remember how. The left-hand drawer sat as it had sat for years, its white paint nicked right where the handle met the front, a small half-moon of wood like a crescent fingernail. The seam where the drawer met the cabinet was a narrow dark. She imagined it as an eyelid. “Do not open,” she told herself, and then, because words are tricks, she said, “Do not be opened.” At 9:16:38, someone knocked. Not Mr. Alvarez. Not three, pause, one. This was a quick soft rapping, tentative and then firmer. A brewer's knock, she thought, someone used to signalling over steam. “Mara?” a voice called. “It's—sorry—it's late.” Her heart did that rising-and-sitting thing again. She stepped to the door and put her eye to the peephole. The light from the hallway was murky with rain and poorly lit tulips. A shape stood there, close enough that she could see the blur of a shoulder, the suggestion of a hand lifted towards the door. 9:16:51. She had promised herself. She had been warned by herself. Both were true and could be broken. She looked back at the drawer. The key in her palm warmed—not hot, not burning, but like someone had breathed on it. She did not turn it in the drawer. She did not touch the handle. 9:16:56. The seam of the drawer darkened, as if night had laid a finger there. She leaned in, breath held. A thread of air slipped out, the tiniest sigh, and with it the impossible scent of salt and sun on wood—the smell of a pier at high noon, of peeling paint and rope, of the ocean being busy. 9:16:59. The left-hand drawer slid open by its own confidence—just a thumb's width. Enough to show a slice of shadow within. Enough for the breath of that salt-wet air to find her and hang there between seconds. On the other side of the door, the voice spoke again, closer. “Mara? Please.” Her hand hovered over the key. It was warm as a living thing. The whole apartment seemed to be a held breath waiting to decide whether it was going to be let out. She glanced at the clock, at the drawer, at the door. The seconds went, bright and merciless. The knob turned—someone testing, not yet pushing, polite and desperate at once. Mara drew in a breath that felt like a line drawn on new paper, and—
