The Lantern’s Debt

The last ferry from the mainland docked at ten, but I missed it. I’d been at a pub in town, nursing a single pint of porter, fighting a headache that had been gnawing at my temples since morning. My friends had left earlier, their laughter fading into the night, leaving me stranded on this rain-slicked island. I could have called a cab, but the thought of my empty apartment, with its creaking pipes and the faint smell of mildew, was worse than the walk home. So I started down the old coast road, a narrow strip of asphalt that hugged the cliffs, with the sea growling somewhere below.

The moon was hidden behind a thick blanket of clouds, and the only light came from the occasional flash of the lighthouse, far out on the point. Its beam swept across the water like a searchlight, catching the whitecaps in stark, momentary relief. I’d walked this road a hundred times, but tonight it felt different. The air was thick with salt and something else, something metallic, like the smell of a copper penny left in the rain. I tried to shrug it off, blaming my headache and the lingering effects of the porter.

About halfway home, I saw the lantern. It was a small, old-fashioned oil lantern, sitting on a rocky outcrop just off the road, its flame burning steady and bright, casting a warm pool of light that seemed to defy the wind. It wasn’t lit by anyone I could see. I slowed, my footsteps crunching on the gravel. A lantern on an empty cliffside, at night, with no one around—it was odd, but not terrifying. I figured a hiker had left it, or maybe a fisherman. I almost passed it by.

But then I saw the note. It was tucked under the lantern, a piece of yellowed paper, folded in half, weighted down by a small, smooth stone. Against my better judgment, I picked it up. The handwriting was spidery, the ink faded, but the message was clear: ‘Do not light the third wick.’ Beneath it, a crude drawing of an eye, surrounded by concentric circles.

I looked inside the lantern. There were three wicks, arranged in a triangle. Two were blackened, as if used, but the third was pristine, new. A shiver ran down my spine. The wind seemed to pick up, and the flame flickered, casting dancing shadows on the rocks. I told myself it was a prank, a stupid island game, but I couldn’t shake the feeling that something was watching me from the dark water below. I left the lantern there, but I couldn’t stop thinking about it. The warning felt less like a warning and more like a dare.

I didn’t intend to light it. But that night, as I lay in bed, the headache pounding, I couldn’t sleep. I kept seeing the lantern, the three wicks, the eye. I imagined what would happen if I lit the third one. What could possibly be so dangerous? I reasoned with myself: it’s just a lantern, just a piece of paper, just a local myth. But the island had its share of stories, stories my grandmother used to tell me, about the old lightkeepers who went mad, about ships lured onto the rocks by false lights, about things that swam up from the depths to answer a call.

The next night, I went back. The lantern was still there, the flame still burning steadily, as if it had never gone out. I brought a match. My hands were shaking. I lit the third wick. For a moment, nothing happened. The flame simply rose, taller and brighter, turning from a warm yellow to a cold, pale blue. The air around me dropped in temperature, and a low humming began, like a swarm of bees, but deeper, more resonant. The lighthouse beam swept across me, and in that brief light, I saw something in the water below—a shape, vast and dark, gliding just beneath the surface. It wasn’t a seal. It wasn’t a whale. It was too long, too angular, and it seemed to move with a purpose.

I stumbled backward, dropping the match, but it was too late. The humming stopped, and a voice, soft and sibilant, whispered in my ear, ‘Thank you. I’ve been waiting.’ I spun around, but there was no one there. The lantern’s flame was back to yellow, but the third wick was now blackened, like the others. I felt a cold hand close around my ankle, and I looked down to see nothing, but the feeling was unmistakable. I ran all the way home, not daring to look back.

Since that night, I’ve changed. I sleep with all the lights on. I avoid the coast road. But something has followed me home. Last night, I found a thin layer of seaweed on my doorstep, arranged in a perfect circle. Tonight, the kitchen faucet drips in a rhythm that sounds like a heartbeat. And in the mirror, when I look into my own eyes, I see the faint, watery reflection of something else, something smiling, waiting for me to make another mistake. The lantern is still out there, on the cliff, its flame eternal. But I know now that it’s not a warning. It’s a promise. And I have already accepted the debt.
