The Lighthouse.

The lighthouse stood alone on Blackstone Reef, a narrow spear of rock rising from the gray Atlantic. Waves hammered its base day and night, throwing white spray against stone that had endured more than a century of storms.

For Elias Mercer, it was home.

Every morning followed the same pattern.

He climbed to the lantern room. Checked the light. Checked the generator. Recorded weather and sea conditions in a leather logbook.

Then he sat beside the radio.

The radio filled the hours.

Fishing captains complaining about weather. Cargo ships confirming routes. Harbor operators exchanging routine messages.

Among those voices was Mara Vance. Port Harrington Radio.

Elias had never met her.

He knew only the sound of her voice.

Steady. Precise. Never hurried.

Most evenings, somewhere near sunset, she checked the lighthouse frequency.

"Blackstone Reef, radio check."

"Loud and clear."

"Good. I'd hate to think the ocean finally swallowed you."

"It'll have to chew harder."

The exchange rarely lasted more than a minute.

Yet it became part of the rhythm of his days.

Some evenings she mentioned fog moving in from the north.

Other evenings she complained about paperwork.

Once she admitted she hated seagulls.

Elias laughed so hard he nearly spilled coffee across the radio console.

After that she occasionally asked whether the gulls were bothering him.

Small things. Meaningless things.

The sort of things people say when they expect to speak again tomorrow.

The first strange transmission arrived on a Tuesday.

A woman's voice broke through static.

"Coast Guard Station Hampton requesting emergency medical assistance. Multiple casualties reported. Repeat, multiple casualties reported."

Elias frowned and made a note in the logbook.

An hour later another transmission followed.

Then another. Different locations. Similar confusion.

"...subjects displaying extreme aggression..."

"...need immediate containment..."

The reports multiplied throughout the day.

By evening, emergency channels were crowded with overlapping voices.

Arguments. Shouting. Fear.

When darkness arrived, Elias studied the distant shoreline through binoculars.

Everything appeared normal.

Traffic moved.

Town lights glowed.

Ferries crossed the bay.

The world looked unchanged.

The radio insisted otherwise.

Over the next several days, the situation worsened.

Authorities declared emergencies.

Hospitals reached capacity.

Roads closed.

No explanation remained consistent for long.

What unsettled Elias most was not what people said.

It was what stopped being said.

Shipping traffic vanished.

Fishing vessels disappeared from routine frequencies.

Entire channels fell silent.

The ocean around Blackstone Reef became strangely empty.

Each evening Mara still checked in.

Her voice grew more strained.

Not dramatically.

Just enough for someone who listened carefully.
