Clara didn't remember how she opened the door.
One moment she was pulling—locked, unmovable. The next, she was stumbling into the corridor beyond it, the air thinner, colder. The humming behind her still pulsed faintly, but distant now, muffled like a machine shutting its eyes.
The stairwell up was longer than she remembered.
By the time she reached the first floor, her hands were shaking, and her blouse clung to her back. She gripped the stair rail and breathed through her teeth, listening.
The Bell building above her was silent.
Too silent.
Not just empty—paused.
The front desk was unattended. The breakroom lights were on, but no one inside. Her watch read 6:14 a.m., but the wall clock by the reception said 6:03. The switchboard panel's clock? 6:26.
She checked her own pocket watch.
6:14. Still ticking.
She moved through the floor slowly, checking each corner like a ghost retracing the steps of its own death.
Everything looked… fine.
But nothing felt real.
She returned to her desk and sat down. Her headset was still there. Her ledger open.
But her notebook—
It had been moved.
She had left it tucked inside her drawer.
Now it sat on her desk, open to a page she hadn't turned.
She stared at it.
A new entry was written at the top—in her handwriting:
> "Stairwell exit unlocked. No sound above."
Beneath it, the time: 6:14 a.m.
Her exact moment of return.
She hadn't written it.
But it was in her hand.
And it was true.
She didn't tell anyone.
Not about the notebook. Not about the door. Not about the voice on the HAL.R0 line that had spoken in two tones—hers and not hers.
Instead, she slipped back into routine.
Or tried.
The morning shift filled in like clockwork—Betty with her tepid coffee, Ruth humming off-key as she settled into her seat. The world resumed its shape.
But Clara didn't feel inside it anymore.
At 9:11 a.m., a call lit up on Line 2. She patched in, voice steady.
"Operator," she said. "How may I assist you?"
A man's voice answered—calm, distracted, mid-yawn. "Yes, I'd like to place a call to—"
> "—Oakland 551, apartment four," Clara said, automatically.
There was a pause.
Then: "...Yes. How did you—?"
She stared straight ahead, grip tightening on the receiver.
"I—I must have seen the card," she said quickly. "It's on your file."
He chuckled. "Efficient. Thanks."
The call connected.
Clara unplugged, heart ticking faster.
She had not seen the card.
She didn't know his name. She didn't know his number. But she had heard it in her own voice—in her mind—a second before he said it.
At 10:23 a.m., it happened again.
A woman requested to speak to her brother.
Clara answered:
> "He's not in. He'll call from Milwaukee at 3:14."
There was silence on the line.
Then: "How could you know that?"
Clara didn't respond.
She simply logged the call.
And under her breath, whispered:
> "Because you already told me."
But she hadn't.
Not yet.
The black notebook had started to feel heavier.
Not in weight—but in content. Pages she hadn't turned suddenly sat open. Entries she hadn't written in her waking mind appeared in her unmistakable handwriting.
She opened it during her second break—alone in the breakroom, sipping cold coffee from a paper cup she didn't remember pouring.
The latest page had no date.
Only this:
> "At 11:17, Betty will spill her coffee. She'll swear. Then she'll laugh. Ruth will say: 'You always talk too fast when you're nervous.'"
Clara stared at it.
She checked her watch.
11:15.
She turned her head toward the glass panel in the breakroom door. Betty was approaching, fast-paced and animated as always, coffee cup in hand, talking with Ruth as they made their way down the hall.
Clara didn't breathe.
She watched the seconds tick.
11:17.
From the hallway:
> "Damn it—Betty!"
A burst of laughter.
Then: "You always talk too fast when you're nervous."
Exactly. Word for word.
Clara closed the notebook slowly, fingers trembling.
She wasn't hearing the future.
She was recording it—before it happened.
She flipped to an earlier page. Another entry she hadn't noticed before:
> "Line 5: The umbrella is open."
"Red 12."
"Echo aligned."
That had been yesterday.
She turned forward.
More entries were appearing. Half a page filled with fragmented phrases she couldn't place—yet.
As if her memory wasn't just leaking anymore…
It was being overwritten.
It started with a whisper.
A single phrase, drifting through her thoughts as she walked to her console after lunch. Not alarming. Not even unusual at first.
Just… oddly familiar.
> "The pattern stabilizes when no one's listening."
She paused mid-step.
She hadn't thought that. Not really. It had arrived in her mind like a dropped sentence from another conversation—fully formed, voiced in her own tone, but not hers.
She sat down.
Plugged in.
The switchboard greeted her with silence.
But the whisper stayed.
That afternoon, as she filed paperwork, she found herself mouthing a sentence aloud—without realizing it:
> "Phase one closes. Phase two awaits."
She dropped the folder.
It was a line from Line 4, three nights ago.
The words had been spoken by a male voice—cool, anonymous. Now they were coming out of her mouth. Involuntarily. Like a cough or a twitch.
At 4:11 p.m., it happened again.
She was helping Ruth reroute a botched transfer when Ruth asked, "Do you have the fallback number?"
Clara opened her mouth to answer—
And instead said:
> "Operator latency: below threshold."
Ruth blinked. "What?"
Clara shook her head. "Sorry—I meant… fallback's 777. My mistake."
She laughed it off.
But inside, her stomach had turned cold.
The phrases were repeating themselves inside her. Her own inner voice was now playing recordings. Things she had heard. Things she hadn't said.
Or hadn't meant to.
The black notebook now lay on her desk, always open.
She flipped to the back.
A new line had been added:
> "Clara. Root memory achieved."
She hadn't written it.
But the handwriting was hers.
Clara didn't sleep that night.
She sat at her kitchen table, the lamp dimmed low, the black notebook in front of her like a relic or a threat.
It had filled itself.
Not completely—but enough. Pages she hadn't written. Entries she hadn't remembered making. Phrases she could no longer trust as her own.
> "Operator 14 silent."
"Pattern loop verified."
"Root-line memory complete."
"You are now Echo."
Her hands hovered over the page.
She tried to write something new.
Something undeniably hers.
> "My name is Clara Varnell."
She paused.
Then wrote beneath it:
> "Today is March—"
But she stopped.
Because she didn't know the date.
Not for certain.
She checked her wall calendar. It said March 12.
But the clock on the wall said 6:14 a.m.
Her wristwatch said 6:07.
Her phone said nothing.
And her notebook…
…already had an entry for 6:14.
> "Entry begins: March 12 – 6:14 a.m. Clara acknowledges memory breach."
She stared at it, heart pounding.
The words weren't hers.
But they described her.
Exactly.
As if the moment she noticed something… had already been written.
She closed the notebook. Slowly. Carefully.
The air around her felt charged.
Her mind no longer felt like hers.
It felt like part of a system.
Not hearing.
Not recording.
Storing.
Repeating.
Forwarding.
She whispered, "What are you using me for?"
The silence answered:
> "Please hold."
