The Ultraviolet Guest

My earliest memory of the house on Balsam Fir Lane is the smell of ozone and burnt dust. That was the year I turned nine, and my mother, a night-shift nurse, kept the master bedroom sealed like a mausoleum. She had filled it with her own quiet rituals: a lavender sachet under the pillow, a stack of unsent letters in the top drawer, and a black light that she left on even during the day, turning the room into a strange, violet twilight. The door was always locked, and we knew better than to touch the brass knob that was always slightly warm, even in winter.

One evening, at the end of October, Mom came home early. The sky was a bruised plum, and the wind keened through the pines that circled our lot. She walked in, kicked off her shoes, and in a voice tight as a wire, she said, ‘Who was in my room?’ My sister Maya, my brother Sam, and I were sprawled on the couch, a bowl of popcorn between us, a sitcom flickering. We all shook our heads. Sam said, ‘No one, Ma. We’ve been here all night.’ But her face was grey, and she wasn’t looking at us. She was looking at the ceiling, at the corner above the staircase, as if she could see through to where her bedroom sat. ‘There’s a shape,’ she said, ‘a dark shape, moving in the glow. I saw it through the gap under the door.’ She had dropped her keys, and they lay at her feet like fallen stars.

We all went up together. The door was still locked, but the keyhole was large, and through it, we could see a sliver of the black light’s glow. The room was silent. Mom unlocked the door with trembling hands, and we crowded in. The room was exactly as she had left it: the bed made, the sachet on the pillow, the black light humming on the nightstand. But on the wall opposite the window, in the faint ultraviolet wash, there was a smudge. It looked like a handprint, but it was too large, and it was only visible where the light hit it, a faint purple against the white wallpaper. Mom let out a slow breath. ‘It’s that damn neighbor boy,’ she said, but her voice was unconvinced. We all went back downstairs, but I couldn’t shake the feeling that the room was still watching us.

That night, I woke from a dream of drowning in violet ink. I needed water, and I tiptoed toward the kitchen, past the staircase. The upstairs hallway was lit only by a nightlight, and I saw it: a shadow, like a column of smoke, sliding out from under Mom’s bedroom door. It moved with a terrible slowness, like a creature underwater, and it paused at the top of the stairs, as if tasting the air. My heart thrummed, but I did not scream. I watched as it drifted down the stairs, toward the living room, and then it simply folded into the dark. I didn’t tell anyone the next morning. I was afraid they’d think I was a liar.

A week later, Mom started leaving the black light on all night. She said it kept her company. But I would hear her pacing, and sometimes she would talk to the air, her voice a low murmur, as if she were negotiating. One night, I pressed my ear to her door and heard her say, ‘I know you’re here. I’ve always known. But you have to leave us alone.’ The sound of her voice was so raw, so broken, that I wanted to break the door down. But then I heard a voice that wasn’t hers. It was a whisper, but not a human whisper—it was like air escaping from a tire, sibilant and cold: ‘I am not leaving. I have waited so long for the light.’

I don’t know when the whispers started following me. Maybe it was the night I saw the shadow by the stairs, or maybe it was before, in the way Mom would sometimes stare at me in the kitchen, her eyes wide, as if she were looking through me. But that spring, I began to hear it in my own room. A soft, repeated syllable, like ‘ssss’ or ‘thhh’, always at the edge of sleep. I would sit up in bed, and my window would be open a crack, even though I knew I closed it. The curtain would stir, and I would see the black light’s faint purple seam from under my own door—because Mom had started keeping the master bedroom door open, just a couple of inches, and the black light bled out into the hallway.

On the night of my ninth birthday, Mom threw a small party. She had invited my reluctant friends, and she had placed a special black light bulb in the living room lamp, so that the whole room was awash in violet. She had cut a potato in half and was demonstrating how to make stamp prints on paper. As she pressed the potato onto a piece of cardstock, she said, ‘See? And you can use different colors.’ But when she lifted the potato, the stamp was not a crude design of a star—it was a handprint. Not mine, not hers. It was huge, spanning the entire paper, with fingers that were too long. My friends gasped, and Mom turned pale. She laughed, a tight sound. ‘That’s not what I carved.’ She threw the potato in the trash and made me open my present. It was a telescope on a tripod, but I never used it. That night, I aimed it out my window, past the pines, at the sky’s black light. And I saw, against the stars, a darkness that had no shape, just a void, and I knew it was looking back at me.

The whispers grew louder. They began to form words, but they were in a language I had never heard, a language that felt like forgetting. Sometimes, when I brushed my teeth, I would see in the mirror shapes moving behind me, but when I turned, there was nothing. Mom started to sleep in the living room. She said the bedroom was too cold, but I knew the black light was making her see things she couldn’t explain. My older sister, Maya, began to have nightmares. She would wake up screaming, clutching her sheets, saying she saw a woman standing at the foot of her bed, but the woman had no face, just a blank, glowing head. The first night I heard her, I ran into her room and found her pointing at the corner, where the black light from the hallway cast a faint glow. ‘She was there,’ Maya sobbed. ‘She was there, and she was counting my fingers.’

I decided to confront the mystery. I saved my allowance and bought a small black light flashlight. One Friday, after school, when Mom was at work, I snuck into her bedroom. The lock was old, and I had learned how to jiggle it with a paperclip. The room was unchanged, but the black light on the nightstand was buzzing louder than I remembered. I pointed my flashlight at the walls, and I saw them: dozens of handprints, in all shades of faint purple, crawling up the wallpaper, along the ceiling, across the window. There was a pattern to them—they all seemed to converge on the spot where Mom’s bed used to be, where her pillow still lay. In the center of that convergence, there was a darker stain, like an old burn. I remembered, then, a story Mom had told me once, about the original owner of the house, a man who had died in a fire, but they never found his body. They had only found a pile of ashes, and a blackened handprint on the wall, as if he had tried to claw his way out.

I didn’t tell Mom what I saw. But I did something that night. I took my own black light flashlight, and I lay in the dark of my room, shining it at the ceiling. I waited. And after a while, I felt the air grow cold, and I heard the whisper, so close now that it was inside my head: ‘You see me.’ And I replied, in a voice that was not entirely my own, ‘Yes.’

Then I saw the shadow descending from the ceiling, slow, like a drop of ink in water. It reached out a long, purple-black hand, and it touched my forehead. The touch was like ice, and I felt my thoughts scatter like startled birds. Immediately, I knew everything: the house had been built on an old burial ground, and the man who had died in the fire had never really died—he had simply changed form, becoming a being that fed on the light of black lights, drinking in the ultraviolet to sustain his shadowy existence. And he had been waiting all these years for someone who could see him, someone whose mind was open to ‘the other spectrum,’ as he called it.

But I also knew how to stop him. The thing he hated was pure, untainted sunlight. I remembered that the black light in Mom’s room was just a normal UV bulb, but there was an old photo album in the hall closet, with a picture of my grandparents standing in a sun-drenched field. I ran to the closet, my heart hammering, and I pulled out the album. The shadow followed me, its whispers now a roar in my ears, but I held up the photo, and the shadow recoiled, shrieking. I ran outside into the cold October night, clutching the photo, and I stood under the moonless sky, bathed in the faint starlight. The shadow hovered at the porch, hissing, and then it retreated back into the house.

I never figured out how to banish it completely. We moved three months later, to a house without any black lights, but I carried the truth with me. I still see the shadows sometimes, when the nights are starless, and I always keep a tiny black light in my pocket—not to bring it forth, but to know where the thing is. And if you ever visit a house with a black light that is left on, and you see a handprint that is too large, do not turn it off. Run. Run and never look back at the violet glow, because the thing that lives there will have already seen you, and it will follow you, waiting for the moment when you too are ready to step beyond the light.

Now, I am gone from that place, but I can still feel the cold touch on my forehead. It is as if a door of perception has been opened, and it can never be closed. I have spent the rest of my life moving from town to town, but every time I see a black light in a store window, I freeze. And I hear that whisper: ‘I am still here.’ I know it is not the house that haunts me—it is the guest I invited in, the one that entered through my willing gaze, and I will never truly be free.
