Don't Let the Building Go Dark

Two seconds before the blackout, I smelled ozone.

That smell was like the air before a thunderstorm, but there was no rain outside. It was the distinctive burnt smell of a high-voltage arc punching through insulation—a danger signal that only someone who’d worked as an electrician for over a decade could recognize instantly.

My name is Maya Chen. Thirty-four years old. Single. The resident electrician at Hawthorne Apartments.

This job was my father’s legacy.

He worked in this building for twenty-seven years, until that winter three years ago when he had a heart attack in the basement electrical room, collapsing in front of those old Schneider distribution panels. By the time I reached the hospital, he was already gone.

He only said one thing before he died. The nurse’s expression was strange when she relayed it to me.

“The red light,” he said. “Don’t let the red light go out.”

I thought it was just delirium. People say all kinds of strange things when they’re oxygen-deprived.

But I still took over his job. Partly because I needed the money, and partly because... I wanted to know what he’d seen in this building.

Three years. I hadn’t seen anything.

Until tonight.

I set down my beer—a can of Budweiser that had gone warm—and looked out the window.

Hawthorne Apartments was an old building from 1973. Fourteen floors, brick and concrete construction, with most of the exterior plaster already peeling off. It sat on the edge of the city in an old industrial district, surrounded by abandoned warehouses and a nearly dry canal.

This building had plenty of problems. Aging pipes, elevator breakdowns, water seeping through the walls. But the biggest problem was its electrical system.

The 1973 design standards were a joke by today’s standards. The main feed was only 150 amps, nowhere near enough to handle modern household loads. Every summer during air conditioning season, breakers tripped like clockwork.

But what really unsettled me was the basement.

Level B1 had a separate electrical room containing equipment I’d never seen before. It wasn’t a standard municipal power interface, but a black metal cabinet that looked like 1950s military equipment. A yellowed label was stuck to the cabinet:

HOLD CIRCUIT — DO NOT DISCONNECT

KEEP ALIVE

My father never explained what it was. Every time I asked, he changed the subject.

“Don’t touch that,” was all he’d say. “It’s old equipment. Just keep it lit.”

That cabinet had a red light. On twenty-four hours a day. In the three years I’d had this job, that light had never gone out.

Until tonight.

The transformer box below the building let out an ear-piercing electrical screech.

Zzzzzt—*

That wasn’t the normal sound of an overload. It was a tearing sound, like someone had ripped a thick power cable apart with their bare hands.

Then came a silence like death.

Not ordinary quiet. The kind of silence where all background noise—the refrigerator compressor, the AC unit outside, the distant highway, even my own heartbeat—was cut off in an instant.

The lights in my apartment didn’t flicker. They just went out.

My body reacted faster than my brain. I was already on my feet, flashlight somehow in my hand from the coffee table.

I felt my way to the breaker panel in the dark.

The backup power indicator light was on. A tiny red dot, painfully bright in the pitch-black living room.

Normally, this red light meant the backup batteries could last four hours. At least enough to keep the emergency hallway lights and elevator communication system running.

But as I stared at it, that red light suddenly flickered.

Click.*

It went out.

My stomach clenched.

That wasn’t normal battery depletion. The backup batteries were replaced just last month—I installed them myself. They couldn’t go from full to zero in two seconds.

Unless something had drained their energy all at once.

I heard a dull impact from the equipment room downstairs.

Thud.*

The sound was heavy, with an aftertaste of twisting metal. Like someone had flipped over the several-hundred-kilogram backup generator.

The ozone smell grew stronger. Strong enough that I could taste it—a metallic bitterness like licking a battery.

I felt the hair on my arms stand up, one by one.

This wasn’t an electrical fault.

I’d worked in this building for three years, seen every kind of malfunction. Short circuits, overloads, ground faults, arc discharges. But no malfunction could simultaneously cut the main power and backup power, and drain a brand-new battery bank in two seconds.

This was deliberate.

Or... not human.

I remembered what my father said before he died.

The red light. Don’t let the red light go out.*

I rushed toward the door.

But just as my hand touched the doorknob, I stopped.

There was a sound outside the door.

Not footsteps. Not voices.

A wet, heavy scraping sound. Like someone dragging a waterlogged thick blanket slowly across the hallway carpet.

Shhhh—shhhh—*

The sound was getting closer.

My hand hovered above the doorknob, motionless.

I didn’t know what was outside the door. But my body knew.

Every cell was screaming: Don’t open it.

Something had awakened in the basement. It had just cut this building’s throat.

And now, it was climbing up.
