I was the only grandchild who made the trek to see Gran, bringing a casserole or a box of her favorite lemon cookies. Her house smelled of mothballs and dried lavender, and the old radio in the kitchen always hummed a tune just below hearing. We’d sit on the porch swing, the chains groaning in a rhythm like a heartbeat, and I’d beg her for the stories she’d told a hundred times. But my favorite was about the house with the impossible room.
Gran was born in the breadbasket of the Midwest, in a town that the railroad had forgotten. Her father, a stern, silent man, worked the grain elevator, and her mother kept a spotless home that seemed to swallow all sound. Gran and her sister, Beth, shared a narrow room at the top of the stairs, with wallpaper that blistered in the summer heat. When they moved to that house, her mother was pleased to find a round rug in the front hallway, perfectly placed under the single, bare bulb. But Gran always said that the rug lay at the center of the strange house’s quietness.
The first thing she noticed was that the house had no square rooms. Every wall slanted or curved, and doorways were shaped like an arch that narrowed at the top, just enough to make you duck even though you didn’t need to. The stairs were the worst: each step was a slightly different height, so she learned to climb without looking down, her fingers brushing the worn banister that felt warm to the touch, even in winter. Beth refused to go upstairs after the first night, claiming she heard something breathing in the walls, but Gran was the bolder one, and she liked the house’s secret shape.
One afternoon, while her parents were in the root cellar, Gran wandered into the parlor where they kept the piano that no one could play. There was a small door behind a velvet curtain, a door she had never noticed before, painted to match the wall. She pulled it open to reveal a narrow staircase leading down, the steps smelling of old earth and something sweet, like rotting apples. She called for Beth, but Beth wouldn’t come, so Gran went alone.
The staircase twisted like a corkscrew, and she counted twelve steps before she reached a small room that was perfectly round, with a stone floor and a single, framed picture on the wall. The picture was of a girl her own age, with braids and a pinafore, staring straight at the viewer. It was the only object in the room, but as Gran stood there, she heard a sound like a distant voice, muffled, as if from behind the walls. She pressed her ear to the cool stone and heard it more clearly: a soft, rhythmic thumping, like a heartbeat. Then the voice, high and thin, spoke her name. ‘Mae.’ Gran’s heart jumped. Only her grandmother called her that, and she was far away. The voice came again, ‘Mae, stay a while.’ The room grew warmer, and the air thickened. Gran felt a pull, a deep urge to sit down on the floor, to stay until the thumping lulled her to sleep. But she was a sensible girl, and she fled.
She told her parents, but they dismissed it as imagination. Her mother said the cellar had a draft, her father said the old house was full of drafts, and they had more important things to do than listen to tall tales. Beth, however, believed her, and that night Beth moved her cot into Gran’s room, even though it was against their mother’s rules. They whispered under the covers, and Gran confessed that she heard the voice again before falling asleep, this time from the pillow, as if the girl had crawled under her ear. She said she felt a cold hand on her cheek, but she was too afraid to open her eyes.
The next day, Gran was determined to solve the mystery. She waited until her parents had gone to town, leaving her and Beth with a list of chores. As soon as the wagon turned the corner, Gran took Beth by the hand and led her to the room. But when they pulled back the curtain, the door was gone. The wall was smooth, and where the door had been, there was only a faint outline, like the mark of a frame that had been removed. Beth started crying, and Gran felt a cold dread in her stomach. She ran her fingers over the seam, and a splintered piece of wood came loose, revealing a small, brass keyhole. It was then that she understood: the room was not always there. It appeared only when she was alone, or when she called it.
For the next few weeks, Gran returned to that wall every day, pressing her cheek against it and whispering, ‘I’m here.’ She never told Beth, but she began to feel that the girl was her friend, someone who knew her better than anyone. The thumping voice grew clearer, and she could almost make out words: ‘Let me in.’ On the last evening before they moved again, Gran’s father announced they were leaving for the coast, where work was better. Gran felt a pang, not sadness, but a strange sense of loss. That night, she snuck onto the landing and saw that the door was open, a warm light spilling out. A small, pale hand was reaching out of the darkness, and a voice said, ‘Take my hand, Mae. We’ll be together.’ Gran pulled back, her heart pounding, and she ran to her room, burying her face in her pillow.
They moved the next dawn, and Gran never saw the house again. But in her new home, she would often wake to find her bed covered in a fine layer of dust, arranged in the shape of a circle. And whenever she stood in a doorway, she felt a tug on her sleeve, as if someone was trying to lead her somewhere. She never told anyone, because she knew no one would believe her, and she feared that if she acknowledged it, the girl would come back.
Gran fell silent, and the porch swing creaked. I noticed the summer dusk had turned to twilight, and the fireflies were beginning to blink. I asked, ‘What happened to the girl in the picture?’ Gran sipped her iced tea, and the glass clinked against her teeth. ‘I never saw her again. But sometimes, when I look in a mirror, I catch a glimpse of her behind me, just for a moment, and she’s smiling. She’s waiting for me to come back and stay.’ I laughed, a little uneasy, and said, ‘That’s just your reflection, Gran.’ She set her glass down and looked at me with those sharp old eyes. ‘The mirror shows you what’s real. That’s what I’m afraid of.’
Years later, when Gran passed away in her sleep, I inherited her house, the one with the porch glider. During the cellar cleanup, I found a locked box in the crawlspace. Inside was an old photograph of a girl with braids, and a note in Gran’s handwriting: ‘If you’re reading this, you’ve found the door. I’m sorry I couldn’t take you with me. But she’s still there, waiting. And she knows your name.’
