The Ceiling’s Arithmetic

The day I moved into the third-floor walk-up on Maple Street, I met Mrs. Kowalski, the landlady, a woman with hands like dried apricots. She handed me a brass key and said, ‘Fourth floor, apartment 4B. You’re the first of the girls to arrive.’ I thanked her and hauled my boxes up the creaking stairs. The building was old, with a smell of mothballs and boiled cabbage. My apartment was small but had tall ceilings and large windows overlooking the street. That first night, as I unpacked, I heard it: a heavy dragging sound from above, as if someone were moving furniture. But there was no fifth floor. The building ended at the fourth. Stairs to the roof were behind a locked door in the hallway. Yet the dragging persisted, punctuated by a rhythmic thumping, like a heartbeat. I told myself it was the building settling, or maybe a raccoon in the walls. But as the week went on, the sounds grew more deliberate. One night, I heard what sounded like a woman’s voice, humming a lullaby I didn’t recognize.

When my roommates arrived — Lena, a nursing student; Priya, an art major; and June, a computer science whiz — I mentioned the noises. They laughed, said it was pipes or old timbers. But then things started happening. I’d leave my coffee cup on the kitchen counter, come back, and find it on the bookshelf. Lena came home from a weekend at her parents’ place to find her pillow flipped to the other side of the bed, and her quilt neatly folded at the foot, a pattern she never used. Priya found her sketchbook open to a page she hadn’t drawn, with a charcoal sketch of a woman with hollow eyes. June, ever the rational one, set up a webcam in the hallway to catch any movement. The footage showed nothing, but one clip had a strange static hiss that sounded like a word, repeated: ‘count’, ‘count’.

We nicknamed it ‘the tenant’, but we never imagined it was anything but our collective imagination. Then the notes started. Small, torn pieces of paper appearing in our shoes, on our desks, written in a shaky cursive: ‘Four of you, one of me. Always odd.’ ‘Three blades, two needles, one thread.’ We tried to dismiss them as pranks, but we all felt a growing unease. Once, I was alone in the apartment, reading in my room, and I heard footsteps in the kitchen. I tiptoed out, but no one was there. The cabinets were open. In the pantry, on the top shelf, a single plate was balanced on its edge, spinning slowly. When I reached for it, it stopped and fell, shattering on the floor. The shards formed a pattern that looked like a door.

One evening, June came running in from the hall, pale. She said she saw a shadowy figure at the top of the stairs, peering down, but the stairs to the roof were locked. We all went out to check, and the padlock was secure. But as we turned to go back in, we heard a key turn in the lock behind us. The lock clicked open. We froze. Then the door to the roof creaked open, and a gust of cold air blew down the stairs, carrying a faint smell of old flowers. We exchanged looks, and without word, we climbed the narrow, dusty stairs to the roof. There was nothing but a few dead leaves and a broken chimney. But etched into the concrete floor was a grid of numbers, like a calendar, with certain dates circled in red. The latest circled date was today.

We ran back downstairs, and that night we heard a loud crash from above, like something heavy had been thrown. Then silence. In the morning, we found that all the pillows in our beds were arranged in a circle on the living room floor, with a single index card in the center, reading: ‘You have three days.’ Lena quit and moved out that afternoon. But Priya, June, and I stayed, thinking it was a final scare. That night, I woke to a pressure on my chest. A figure sat on me, a woman with long black hair covering her face, her weight cold and heavy. She leaned in and breathed into my ear: ‘Your turn to be the odd one.’ I couldn’t scream. I passed out.

When I came to, I was on the roof, lying in the center of that etched grid. The moon was high, and the numbers were glowing faintly. I saw a circle around my own date, three days from now. I stumbled to the edge, looked down at the street, and saw all three of my remaining roommates looking up at me, their faces blank. They waved, and then each turned and walked back inside. I realized then that the sounds, the movements, the notes, were not from a ghost, but from the building itself, trying to balance a ledger. There were four of us, but there should be three. One of us had to become part of the structure. I knew then that I was the one. My name is Alice. I live in 4B, on the fourth floor, but I don’t live there anymore. I live above, in the space between the ceiling and the sky, and I count the days until the next occupant arrives. There were four of us. Now there are three. And I am the ceiling’s arithmetic.
