The old observatory perched on the hill had been converted into a lecture hall, its domed ceiling still scarred with the tracks of a former telescope. Dr. Aris, a man as gray and creaking as the building itself, delivered his lectures on celestial mechanics to a sparse audience of twenty-three. I always chose the last row, where the curved wooden benches met the wall and the light from the projector cast my shadow long and distorted. It was there, on a rain-slicked Tuesday, that I first saw her.
She was not a student. She was not a ghost in the traditional sense. She was more like a sketch that had been left on the board, but she was three-dimensional. She sat cross-legged atop the whiteboard, her knees tucked under her chin, and she watched Dr. Aris with an unnerving stillness. Her skin was the color of chalk dust, and her dress was a faded blue, like old ink. Her hair was the only thing with any life—a curtain of black that swayed slightly, though there was no draft. I assumed she was a projection, a trick of the light, but when I blinked, she remained.
For three weeks, she appeared only in that class. She never moved, never blinked, never acknowledged me or anyone else. Her gaze was fixed solely on the professor, but not on his face—on his hand, the one that scribbled equations across the board. I began to sit closer, not to see the board better, but to see her. I told no one. I feared the laughter, the pity. But I also feared her.
One Thursday, I stayed after class to ask Dr. Aris a question. As I approached the podium, I saw her still perched on the board, but now she was looking at me. Her head was tilted, and her lips moved silently, as if she were mouthing a word. I tried to ignore her and asked Dr. Aris about the orbital mechanics of binary stars. He answered in his monotone, but I couldn’t focus. Her lips moved again, and I realized she was saying my name—the name I had never shared with anyone in that room. I turned to leave, but as I reached the door, a high-pitched giggle echoed behind me. I spun around; the board was empty.
That night, I couldn’t sleep. I kept seeing her face, her silent mouthing. By morning, I convinced myself it was a stress-induced hallucination. But when I entered the lecture hall for the next session, she was waiting for me. This time, she wasn’t on the board. She was sitting on Dr. Aris’s shoulder, her legs dangling over his chest. The professor seemed oblivious, but as he turned to write on the board, she reached out and touched his ear. He paused, rubbed his ear, then continued.
I began to take notes as a distraction, but when I looked down, my notebook was filled with the same word, over and over: “Mine.” I had no memory of writing it. I looked up, and the girl was staring at me, her mouth stretched into a smile that was too wide. “Mine,” she whispered, and I felt a cold hand on my shoulder.
I fled the lecture hall, my heart pounding. I ran to the campus clinic, but the nurse found nothing wrong. I told her about the girl, and she gave me a referral to a psychologist. But I didn’t go. Instead, I returned to the observatory that night, determined to confront her.
The building was locked, but the side door was ajar. I slipped inside, the silence heavy. The projector was off, but the board glowed faintly as if covered in luminous chalk. And there she was, standing on the floor, her dress pooling like liquid shadow. “You came,” she said, and her voice was like the scratching of a pen.
“What are you?” I asked, my voice trembling.
She tilted her head, and for a moment, she looked almost sad. “I am the one who watched him. I was his student, many years ago. I loved him from afar, but he never saw me. I died alone in this building, and my love turned to something else. Now I watch over him, so no one else can take my place.”
I realized then that Dr. Aris’s lectures had been the only constant in her lonely existence. She didn’t need him to see her; she needed him to never see anyone else. And she had chosen me as the next threat.
“I don’t love him,” I stammered. “I just wanted to learn.”
“It’s too late,” she said, and her form began to blur, the chalk-white skin cracking like dry paint. “You’ve seen me. You’ve heard me. You are part of this now.”
I turned to run, but the door had vanished. The walls of the observatory seemed to close in, and the girl began to recite the equations I had seen on the board, but in a singsong voice that made my blood curdle. The numbers and symbols peeled off the walls and swirled around me, sharp as glass.
When I woke, I was outside, lying on the wet grass. The sun was rising. I never returned to the university. I transferred to a community college in another state, but sometimes, in the corner of my eye, I catch that same painted child, sitting atop a whiteboard, her lips moving silently. She always finds me. And she always whispers the same word: “Mine.”
