The Silent Arithmetic

My name is Danny, and I’m fifteen. About eight months ago, my family moved into a renovated farmhouse on the edge of the Dahlia wetlands. We left a cramped apartment in the city, where I used to hear scratching inside the walls, but Mom said it was just pipes. The farmhouse was supposed to be a fresh start, a place where Dad could breathe and Mom could finally paint. The first month was peaceful, filled with the smell of damp earth and the sound of crickets. Then the numbers began.

It started with Dad. He’s a high school math teacher, and he’d spend hours grading papers at the kitchen table. One night, he claimed his calculator kept changing digits on its own. ‘Seven point two becomes seven point two zero zero four,’ he muttered, shaking the device. I joked that maybe he needed new batteries. But then he started writing odd equations on the windowsill in chalk. ‘0 + ∞ = ∞’ and ‘3.14159… lies between us.’ Mom found them and scrubbed them off, but they reappeared every morning.

Mom’s turn came next. She’s a painter, and she set up her easel in the old sunroom. She began hearing a faint ticking, like a metronome, even though there was no clock in the room. She’d call me in to listen, but I heard nothing. Then she started seeing a pattern in her paint palette, a sequence of colors that seemed to spell out ‘COME HOME.’ She thought it was a hoax, but the paints were dry, and she hadn’t mixed them that way. She stopped painting and took to sleeping in the living room, away from the sunroom.

I started noticing things in the kitchen, which adjoined my room and my sister’s room. At night, I’d hear the silverware drawer slide open and then shut, as if someone were counting the forks. The refrigerator magnets would rearrange themselves into equations: ‘2 × 8 = 16’ but the 6 was always upside down. One night, I woke to find a string of numbers written in wet flour on the counter: ‘1 1 2 3 5 8 13 21 34 55 89 144…’ I recognized it as the Fibonacci sequence, but the last number was smeared, and next to it, in shaky digits, was ‘WHO IS NEXT?’

Two weeks ago, Mom left me and my little sister, Lily, alone for the afternoon to visit a friend in town. She was gone only three hours. Not long after her car disappeared down the dirt road, Lily, who was on the living room couch, said, ‘Danny, the kitchen door moved.’ I looked up from my phone, and we both saw it. A small figure stood in the doorway, a girl no older than seven. She had a pale, waxy face, short black hair that seemed to absorb light, and she wore a white dress, slightly too long, the hem brushing the floor. She stood perfectly still, as if calculating something. She stared at us, then slowly raised her hand and pointed at the ceiling. Lily screamed, and the girl vanished.

I didn’t tell Mom when she returned. I didn’t want to worry her. But that night, I had a dream. I was standing in the kitchen, and the girl was there, sitting at the table with a dusty chalkboard. She wrote on it: ‘There are 1000 steps between this world and the next. Show me the way.’ I woke up sweating, and my bedroom door was slightly ajar, even though I knew I’d closed it. I crept downstairs, and in the dim light, I saw the girl standing in the center of the living room, her back to me. She was counting softly, ‘One, two, three, four…’ I turned on the light, and she was gone. But on the wall, written in a jagged hand, were the words: ‘I have been counting your steps since the day you arrived.’

Last Saturday, Dad asked me to look at something on his computer. He was in his study, which used to be a pantry. As I sat down beside him, the screen flickered, and a document opened by itself. It was a spreadsheet, and rows of numbers were filling in rapidly. Dad’s face went pale. ‘What is this?’ he whispered. The numbers were our heartbeat rates, our sleep schedules, our GPS coordinates. Then, a new column appeared with the heading ‘DAYS REMAINING.’ Next to my name, it said ‘∞’ and next to Lily’s name, a finite number: ‘7.’ Dad stared at it, then slammed the laptop shut. ‘It’s a prank,’ he said, but his hands were shaking.

That night, I couldn’t sleep. I sat in the kitchen with a flashlight, listening to the house settle. The girl appeared in the corner, but this time she was holding a small wooden ruler. She walked toward me, her bare feet making no sound on the tile. She stopped right in front of me and held up the ruler. It was etched with strange symbols. She spoke, her voice a thin, dry whisper, ‘You have three days to solve the equation. If you fail, she will become one of us.’ I tried to ask what she meant, but she faded, leaving a faint smell of formaldehyde.

The next morning, Lily was gone. We searched the house, the barn, the edges of the wetlands. No trace. Mom was frantic, Dad called the sheriff, but I knew the girl had something to do with it. That evening, in desperation, I went into the study and opened the laptop. The spreadsheet was still there, and the numbers next to Lily’s name now read ‘0.’ I stared, and the cursor moved on its own, typing a message: ‘The answer is 42. You have until midnight.’ I looked up, and the girl was standing in the doorway, watching me. She tilted her head, and for the first time, she smiled. It was a slow, deliberate smile, as if she had just solved a problem I had been struggling with.

I think about that smile now, sitting in my room, as the clock ticks past midnight. Lily hasn’t come back. The girl’s reflection in the window shows not a child, but a shambling figure with hollow eyes, counting the seconds until I’m next. I realize now that we never left the old house. We just exchanged one haunting for another. The arithmetic of the dead is patient, and I am running out of numbers.

In the morning, I will go to the sheriff, but I already know what he’ll say: sometimes, children vanish in the wetlands, and the only sound is the crickets, and the only writing is on the windowsill: ‘Remember the 42.’ But I can’t remember. I can only hear Lily’s voice, from somewhere deep below, counting, counting, counting.
