The night was too quiet. The kind of quiet that makes every sound feel deliberate — the hum of the refrigerator, the sigh of pipes, the faint buzz of electricity in the walls.
Aria sat cross-legged on her living room floor, surrounded by a scatter of old cassette tapes. The floor around her was a mosaic of past lives — cracked cases, faded handwriting, a smell of dust and magnetic tape.

A single lamp glowed beside her, its light cutting a small circle into the darkness. The clock on her wall blinked 1:52 a.m.

She was supposed to be sleeping. But she couldn’t. Not after what she and Rylan had found — a voice on the USB drive that shouldn’t have existed, words that seemed to rewrite themselves every time they replayed the audio.

So here she was, rummaging through her own past, trying to remember where the first distortion began.

Each tape label was like a breadcrumb:
“Broadcast Practice — Year 1.”
“Dr Hale — Lecture Notes: Resonance.”
“Mirror Study – Session 2.”

She lined them up in neat little rows, her fingers trembling slightly as she brushed dust off one by one. But when she reached for the next, her hand froze.

Tape 04. Missing.

The one that should have been labelled “Mirror Study – Session 1.”
The one she remembered vividly. The one where Hale’s voice first told her:

“If you listen long enough, the echo starts listening back.”

Aria’s chest tightened. She looked around, half-expecting it to appear somewhere — behind the stack, under the shelf, in some forgotten drawer. But the more she searched, the colder the room felt.

Outside, the city lights flickered through her blinds — rhythmically, like a pulse.

And faintly, beneath the hum of her equipment, she heard something she couldn’t quite name.
Not static.
Not silence.
Something in between.

At the precinct, the night shift was thin and exhausted. Rylan sat in the tech lab, sleeves rolled up, eyes burning from the screen’s harsh glow.

He was listening to Aria’s old broadcast recordings — again. Over and over.

At first, he thought the glitches were random. A failing transmitter. Cross-frequency interference. Something easy. Something logical.

But the deeper he looked, the less sense it made.

He leaned closer, studying the waveform on the monitor — zooming into the smallest blip of distortion in her voice. When he isolated it, the sound played faintly through the speakers.

A whisper. Not static.
An echo of her own voice — but out of sync.

Two Arias, one just milliseconds apart.
One human. One not.

Rylan replayed the clip, then layered the two frequencies together. The overlap produced a strange pulse — rhythmic, deliberate. Almost like Morse code.

He exhaled sharply. “Someone’s embedding a pattern.”

He rubbed his temple, trying to process the implications. Either this was a deeply advanced hack, or… something far stranger. Something personal.

When Aria arrived at the lab later that morning, she still looked like she hadn’t slept. Her hair was pulled into a loose braid, her coat thrown on over mismatched clothes.

“What did you find?” she asked, voice low.

Rylan hesitated, then pressed play.

Her voice filled the lab — calm, smooth, professional. “This is Aria Vale, and you’re listening to The Silent Hour.”

Then, faintly, just beneath it:

“This is Aria Vale…”
“…can you hear me?”

Aria’s face went pale. “That’s—no. That’s not possible. I’ve never said that.”

Rylan studied her expression, his voice measured. “Have you ever done any sound experiments with Dr Hale? Anything that might’ve involved layering your own voice?”

She shook her head slowly, her hands gripping the table. “He had projects—things he said were about emotional acoustics. He called it the Mirror Sound. Said sound could reflect human emotion, not just capture it. But I never—” she stopped, eyes narrowing in memory— “I never participated. Not directly.”

The detective’s jaw tightened. “You’re sure?”

“I thought it was just theory.”

They sat in silence for a long moment. The only sound was the low buzz of the monitor. Then Rylan rewound the audio file.

And this time — the whisper changed.

Where there had been nothing before, now a new phrase emerged, almost beneath the threshold of hearing:

“He’s listening too.”

Aria ripped the headphones off, her voice shaking. “It changed… Rylan, it changed!”

He stared at the monitor. “That’s impossible.”

But deep down, both of them knew — impossible had stopped meaning anything the moment The Voice had spoken the first confession.

That night, Aria couldn’t stay in her apartment. Every sound made her flinch — the elevator’s groan, the pipes sighing, her own breathing.

She finally sat on the couch, knees pulled up, radio off. And still… faintly, she heard it. A whisper just at the edge of hearing, as if the walls were replaying something she’d said long ago.

Then a voice — familiar, calm, gentle.

“You remember the mirror, don’t you?”

She froze. It was Hale. Her mentor’s voice. The same tone he used during her earliest days in training.

“The mirror doesn’t reflect what’s real, Aria. It reflects what you fear.”

Her hands shook violently. She turned the radio on, desperate for noise, for static — for anything to drown it out.

But what came through wasn’t static. It was a breath. Then a whisper:

“Aria…”

And then a knock at the door.

She nearly screamed.

But when she looked through the peephole, she saw Rylan. Standing there in jeans and a hoodie, his expression unreadable — but softer than usual.

“I couldn’t sleep,” he admitted, voice low. “You weren’t answering your phone.”

“I unplugged it,” she murmured. “It started… talking back.”

He frowned, but didn’t argue. Instead, he stepped inside, scanning the equipment scattered across her living room. “You’ve been listening again.”

“I keep hearing things. Hale’s voice. My own. I don’t know what’s real anymore.”

Rylan paused. Then, quietly: “You’re not losing your mind, Aria. Whatever this is, we’ll find it. Together.”

It was the first time he’d said we without hesitation.

For a brief moment, the tension between them softened — two people caught in the same strange current, both haunted by voices of the dead.

Hours later, just before dawn, the ON AIR sign glowed red again in the studio. Aria’s hands shook as she adjusted the mic. She tried to sound calm — as if her world wasn’t fracturing around her.

“This is The Silent Hour,” she said softly. “And you’re not alone tonight.”

For a while, everything was quiet. The lines stayed dead. Just her and the hum of the console.

Then — click.

The line connected.

Her pulse spiked.

The Voice had returned.

“You shouldn’t have looked, Aria,” it said.
“You’ve changed the frequency.”

She swallowed hard. “Who are you?”

“I told you. I’m the echo.”

Her blood ran cold.

“And the detective—” the Voice paused, almost amused—
“—he’s next.”

Then, clearly, through the static:

“Detective Rylan Cross.”

The line went dead.

Aria sat frozen, the studio silent around her — except for one faint sound through the headphones.

A heartbeat. Not hers.
