I’m A Deep Sea Welder Working 500 Feet Underwater. Someone Just Knocked On The Hatch.
At this depth, the pressure is enough to crush a tank. We are the only living souls for miles. So when I heard the rhythmic banging on the metal hull, I knew we were already dead.

I’m A Deep Sea Welder Working 500 Feet Underwater. Someone Just Knocked On The Hatch.
There are jobs that are dangerous, and then there is saturation diving. I live in a pressurized metal tube, barely the size of a minivan, suspended 500 feet below the surface of the North Sea. For 28 days, this capsule is my entire world. Outside, the water is pitch black, near freezing, and the pressure is so immense that if the hull breached, my body would turn to jelly in a fraction of a second.
It’s just me and my partner, Miller. We take turns. One sleeps, one monitors the comms. It’s a quiet, claustrophobic existence.
Or it was, until 04:00 hours last night.
Miller was asleep in his bunk, snoring softly. I was reading a book, trying to ignore the constant hum of the life-support scrubbers. The ocean outside was silent. Down here, sunlight never reaches. It is a world of eternal night.
Then, I heard it.
CLANG. CLANG. CLANG.
Three distinct, metallic strikes against the outer hull of the diving bell.
I froze. My first thought was mechanical failure. A loose cable? A piece of debris falling from the support ship above?
I waited.
CLANG. CLANG. CLANG.
It was rhythmic. Intentional. Someone—or something—was hitting the outside of the bell.
I felt a cold sweat break out inside my suit. "Miller," I hissed, shaking him awake. "Wake up."
Miller grunted, rubbing his eyes. "What? Pressure drop?"
"No. Listen."
We both sat in silence. A minute passed. Then, it happened again, louder this time, right next to the reinforced glass porthole.
KNOCK. KNOCK. KNOCK.
Miller’s face went pale. "Is there another diver down here? Did the topside send a rescue team?"
"Topside would have radioed us," I whispered. I grabbed the comms mic. "Topside, this is Bell 2. Do we have company down here? Over."
Static crackled. Then the voice of the supervisor came through, clear and calm. "Negative, Bell 2. You are the only objects on the sonar. Why?"
I looked at Miller. "Topside, we are hearing... knocking. On the exterior hull."
There was a long pause. "Bell 2, sonar is clear. It’s probably just the umbilical cable hitting the side in the current."
It wasn't the cable. The cable makes a scraping sound. This was knuckles on metal.
I moved toward the small, circular porthole. It was the only window to the outside world. I turned off the internal cabin light so I could see out into the darkness. I pressed my face against the thick glass, peering into the abyss.
At first, I saw nothing but the black void. Then, I turned on the external floodlights.
The beam of light cut through the murky water, illuminating the silt and particles floating like dust. And then, I saw it.
It was floating about five feet away from the glass.
It looked human, but it was wrong. It was naked, its skin pale white like a dead fish's belly. It had no scuba gear. No breathing apparatus. No tank. At this depth, a human body should be crushed instantly. The lungs would collapse.
But this thing was swimming.
It had long, drifting hair that floated around its head like a halo. It turned slowly to face the light. It had no eyes, just smooth skin where sockets should be. And its mouth was a vertical slit, like a gash in its face.
It drifted closer to the glass. I wanted to scream, but my voice was stuck in my throat. Miller was looking over my shoulder, gripping my arm so hard it hurt.
The thing reached out a hand. Its fingers were long, with extra joints. It tapped gently on the glass, right in front of my face.
Tap.
Then, a voice came over the comms speaker. But it wasn't the supervisor. It was a wet, gurgling sound, broadcasting on our private frequency.
"Open... the... door. It's... cold."
I scrambled back from the window. "Topside! Pull us up! Emergency ascent! NOW!" I screamed into the mic.
"Bell 2, calm down. We can't pull you up that fast, you'll get the bends and die. What is happening?"
I looked back at the porthole. The thing was pressed against the glass now. Its vertical mouth opened, revealing rows of translucent, needle-like teeth. It wasn't knocking anymore. It was latching on.
We are currently being winched up. It takes hours to decompress safely. But the banging hasn't stopped. It’s getting louder. It sounds like the metal is starting to dent.
I don't think we’re going to make it to the surface.
