The Silent Ward

Groote Schuur Hospital – 03:12 AM

The fluorescent light above the nurse's station buzzed like an insect trapped in glass. Nurse Talia Jacobs blinked at it, unsure whether the flickering was real or if her eyes were just playing tricks on her. She rubbed her temples. It had been a long shift, much longer than usual and the night refused to end.

Groote Schuur had always been quiet at this hour, but tonight was different.

It wasn't silence, it was the absence of sound, a pressure in the air, almost as if the building was holding its breath.

She checked the monitors again, and everything looked normal, all except for ward C3. The heart monitor had flatlined.

Talia frowned. That wasn't possible.

She reached for the intercom to call the night doctor, but something, instinct perhaps, made her stop. Instead she stood up, pulled her cardigan tighter around her, and started down the hallway. The polished tiles squeaked under her shoes.

Ward C3 had been empty for weeks. It wasn't even on her ward roster.

But the monitor had registered a patient. A heartbeat. Then a flatline.

She reached the door and paused. The window was dark. The small square of reinforced glass showed nothing but a shadow inside.

She reached for the handle. It turned too easily.

The door creaked open.

The first thing that hit her was the smell. Not blood, not antiseptic, but the sour, metallic tang of something old and rotting, like meat left in the sun.

Talia stepped in, hand groping for the light switch.

The lights flickered once. Then held. The room was empty. There was no patient, not even a bed. Just a cold gurney pushed to the corner, yet the heart monitor was on and it was still printing.

She walked closer. Paper rolled out slowly from the machine, drawing a flatline across the strip, but something was off.

The line wasn't flat anymore, it was jagged, and erratic, as if someone was trying to write with it.

Talia leaned ib and between the blips she saw it, it wasn't a random noise, but words. A name scrawled over the paper, written over and over again, in ragged black spikes across the ECG strip: Asanda.

She stepped back, and that's when she heard it, a whisper, behind her, no breath, no voice, just the idea of a voice, a syllable in her spine.

"Don't turn around."

Her blood ran cold, but she ignored it and turned anyway, only to find that the room was empty, and yet, the light dimmed, and her breath fogged in the air as if something was drawing heat from her lungs.

A second heartbeat appeared on the monitor, and again no body, just the sound, the sound of steady beating, like something waking up.

03:29 AM – 17 minutes later

By the time security arrived, Nurse Talia Jacobs was sitting in the corner of Ward C3, rocking back and forth, face streaked with tears. She wouldn't speak or blink, she just kept writing the same word on the floor with her finger, over and over in invisible ink: Listen.

Cape Town Central Police Station – 09:44 AM

Detective Siya Ndlovu sipped cold coffee and stared at the file in front of her like it was a snake waiting to strike.

Another body. Another hospital. Another face frozen in an expression no living person could wear.

She closed the file and exhaled.

Three deaths in one month. All in Groote Schuur. All after midnight. All under surveillance, and yet the tapes showed nothing but static during the exact time of death.

Her partner, Detective Nathan Marks, leaned over her desk.

"You look like hell," he said.

"Thanks," she muttered.

He dropped a brown file on top of hers.

"Got a call this morning. Another incident. Not a death this time, a nurse was found in shock, mumbling some nonsense about a locked room that shouldn't have been open."

Siya opened the new file and froze. Ward C3.

She remembered it. Not the ward, but the number. It gnawed at the edge of her memory.

"Groote Schuur again?" she asked.

Marks nodded. "Same floor. Psychiatric wing. What's left of it."

Siya stood. "Let's go."

They arrived at Groote Schuur Hospital at 10:37 AM. The hospital loomed like a mausoleum under the grey Cape Town sky. Siya hated hospitals in general, but now in particular she was hating this place, not because of the deaths, or the smell, or the endless white corridors, but because of what it held and what it refused to let go.

They parked in the visitor's lot, flashed their badges at the front desk, and took the elevator to the third floor.

The psychiatric wing had been partially shut down after budget cuts and "incident reports" that never made it into public record. Half of it was still operational, outpatient therapy, trauma support, and a few secure rooms, but the far corridor had been cordoned off for over a decade, rxcept now, it wasn't.

A young doctor with trembling hands met them at the nurse's station.

"Dr. Visser," he said, adjusting his glasses nervously.

"You're here about Nurse Jacobs?"

Siya nodded. "Where is she?"

"In isolation. She's not coherent. Keeps repeating the same word. 'Listen.' Sometimes 'Asanda.' Does that name mean anything to either of you?"

Siya went still.

Marks glanced at her but said nothing.

"She found something in Ward C3?" Siya asked, voice tight.

Visser hesitated, then gestured down the dim corridor. "That room shouldn't even have been open. It's not on the active system. No keycard access. No patient assignment. Yet someone logged in under a ghost profile and the monitors started recording, motion sensors triggered, but-"

"No footage," Marks finished.

"Right," Visser said, relieved and unnerved at the same time.

Siya started walking. Her boots echoed down the tiled floor, every step louder than it should've been. The corridor had that strange hospital sterility, clean, but haunted and far too quiet.

Ward C3 looked like any other door, until you looked at it for too long.

The numberplate was scratched. Not vandalized, worn, as though time itself had tried to erase it.

Siya touched the handle, it was cold. She opened the door. The air was still, dense, like breathing underwater. The walls were clean, the floor freshly mopped, and the equipment silent, but the heart monitor was still running, and paper was still spooling out.

Siya walked over, reading the strip. Flatline. Flatline. Then a spike. Then another.

The spikes didn't follow a rhythm, they followed a pattern, like a Morse Code, or writing.

She reached into her coat and pulled out her phone, snapping a photo of the strip.

Marks stood in the doorway. "Looks like a prank. Or faulty wiring."

"No," Siya murmured. "This is deliberate."

She held up the ECG printout.

The spikes spelled something, Asanda, the name again and again, malformed but unmistakable.

"She's calling out," Siya said.

"Who is?" Marks asked.

"My sister."

Backstory Flash – 13 Years Earlier

Groote Schuur. Student wing. Siya and Asanda.

They were two halves of a whole, one was brilliant and analytical, whike the other was intuitive and sensitive.

Asanda had volunteered for a student internship at the hospital. She'd wanted to study abnormal psychology. She wanted to help the patients no one else could reach, but one night, she never came home.

There was no trace of her, no note either, and the CCTV went dark, then the case went cold.

Siya never believed it was just a disappearance.

She believed the hospital swallowed her sister. Now, she had proof. Or at least a beginning.

Groote Schuur Hospital – Sublevel Archives – 11:41 AM

"You sure we're allowed down here?" Marks asked, glancing around the dim stairwell as they descended past the Authorised Personnel Only sign.

"Nope," Siya said, pushing the door open.

The archives were cold. The kind of cold that didn't come from bad insulation but from being forgotten by the world.

Fluorescent lights flickered on as they entered. Endless metal shelves stretched into the gloom. Folders, tapes, handwritten logs, records that never made it into digital storage.

Marks pulled on gloves. "You're looking for Asanda's file?"

"No, I already tried that. Her file was wiped two weeks after her disappearance. Not redacted, but erased."

"So what, then?"

"I want to know what Ward C3 was before it was closed, and why."

They searched in silence. The kind of focused, tense silence that only came from people who knew something was watching, just not from where.

After twenty minutes, Siya stopped.

A thin folder, perhaps misfiled, was stuck between Cardiology 1983 and Neurology 1984.

"Threnody – Internal Use Only."

She opened it.

There were typed reports, graphs, and psychological profiles, but there were no patient name, just a codename: Echo-3.

Under notes: "Subject demonstrates auditory sensitivity to sub-threshold frequencies."

"In prolonged exposure, reports 'voices beneath the noise.' Mentions a song. Repeated term: The Choir Beneath."

"Memory fragmentation increased after Session 4. Claims to see her own reflection 'whispering back.'"

Siya's hands trembled slightly.

Marks read over her shoulder. "Project Threnody?"

"Sounds like an MKUltra knockoff."

Siya flipped the page. There was a photo stapled to the last entry, it was grainy, and shadowy, but unmistakable.

Diya had to believe it was her sister Asanda. Her hair was longer, her eyes were hollow and she was strapped to a hospital chair in a soundproof room.

The date on the record was October 28, 2011.

"This was Three weeks after her disappearance." Siya thought.

Marks looked at Siya, his expression unreadable.

"You were right," he said quietly.

"She never left," Siya replied.

Above Ground – 12:15 PM

When they went back up, Dr. Visser was gone and so was the nurse at the station. In fact, the entire hallway was empty. Not just understaffed, but abandoned. No phones were ringing, there was no movement. It eas an ear-deafening silence.

Then came the sound, itvwas a low hum, just at the edge of hearing, like someone humming through walls made of bone and the ECG printer in Ward C3 started up again.

Siya and Marks turned to look. They saw the door was open, but no one had opened it and from inside came a voice, it was not loud, nor was it spoken, just a vibration in the spine.

"You heard her. Now hear us."

Down in the Sublevel Morgue at 12:23 PM, Talia Jacobs was laying on the table, dead.

They found her on the slab, though no one had logged her in and no autopsy had been scheduled.

She lay there with her eyes open, her mouth stretched wide into an inhuman shape, like she had died in the middle of a scream she hadn't chosen, and on the wall above her body, the words "LISTEN" were written in dried blood:

Siya needed air. She burst through the stairwell door and stepped into the sunlight, on the roof top, but it didn't help. The city stretched out below, familiar and alien.

Devil's Peak loomed over the skyline like a watching god. Cape Town buzzed below as if the hospital weren't harboring something ancient and hungry.

Marks followed her up, holding the Threnody file. "This changes everything," he said.

"No," Siya replied, staring across the city. "This confirms everything I feared."

She closed her eyes and remembered her sister's laugh. The way Asanda used to hum when she was nervous. That hum was the same pattern she'd heard on the ECG strip.

It wasn't random, nor in broken signals. It was a song, a message, and a warning.

Marks moved beside her. "Whatever Project Threnody was, it didn't end."

"It's still running," Siya said. "Still feeding on people."

Then her phone rang. It was an unknown number. Siya answered the call, but there was no voice, just a crackling sound.After a short while there was a familiar word, drawn out in a distorted whisper that chilled her marrow. "Siya..." Then the line went dead.

Siya's hand shook. "It was her," she whispered. "I know it was."

Marks didn't argue.

They both stood in silence, the wind carrying with it the faintest sound, too faint to be real.

A low, discordant hum, like a thousand mouths singing from beneath the earth.

Elsewhere on the unknown Sublevel, the lights buzzed and the machines whirred. Behind a thick pane of observation glass, a young woman sat still in her chair, her eyes were closed and her breathing was shallow.

Her name was Asanda. She was alive and she was listening.

All around her, in the shadows of the room, something moved, something tall, faceless, and waiting. And somewhere, a voice whispered again, not to her, but through her: "Let them come."

It was around 1:09 PM Siya and Marks took the service elevator back to ward C3.

The elevator groaned as it descended, deeper than the building's plans suggested it could go.

Marks checked his phone again, there was no signal, not even a flicker of reception.

"This is a bad idea," he muttered.

Siya didn't respond. She stared at the glowing panel, watching the numbers descend past Sublevel 3. Then, past 4. Then...5

There was no Sublevel 5 in the hospital's blueprints.

She'd found the override panel behind a fire extinguisher mount near the morgue. A hidden lift control that didn't appear in any public schematic. When she entered the code scrawled on the back of the Threnody file-Δ53-ECHO-the panel lit up and opened this shaft.

The metal box shuddered. For a moment, Siya thought it would stop. Then it lurched again and continued.

When it finally came to a halt, the doors opened with a hiss !and they were surrounded by darkness. The only illumination came from an emergency light flickering above a sealed door labeled: ECHO WARD – RESTRICTED ACCESS

Siya stepped out first. Her breath misted in front of her.

Marks followed, flashlight sweeping side to side.

The hallway was tight and cramped. Pipes ran like veins along the ceiling. Everything was covered in a thin layer of condensation, making the walls seem to sweat.

"This place wasn't just hidden," Marks said. "It was buried."

Siya nodded. "And forgotten on purpose."

She reached the door.

It was locked with a biometric scanner long dead from lack of use, but someone had pried it open before, because the metal was warped slightly, and scratched at the edges.

Inside, the air was colder and still.

Insode ECHO ward , the room was lined with soundproof insulation, some of it peeled away to reveal thick concrete underneath.

Empty beds, restraints ans apeakers mounted in every corner, though not for music, but for broadcast.

There were no windows or security cameras, just wires, and the smell of old electricity and damp cloth.

Siya crouched by a terminal. Dust blanketed the monitor, but a blinking cursor told her something was still alive in the system.

She wiped the screen and tapped a few keys and the login prompt blinked.

"Worth a try," she muttered.

She typed in ECHO-3.

Password: asanda

Access was granted and files flooded the screen.

Audio logs, session transcripts, and neural scans, but ine file was newer than the rest, it was dated just five days ago.

Siya opened it. It was an audio recording. She hit play and at first there was silence, then a low, rhythmic pulse, and then, beneath it: a voice.

It was a female voice, it was weak and whispering. "They come through the silence. Through me. Through us all."

Then another voice, it was a male voice, it was distorted, and digital, like a scientist recording logs, saying, "Subject Echo-3 has begun transmitting on her own without stimulus. The signal is stable. We are recording now."

The audio was cut abruptly, then there was static and after a while laughter, but this laughter wasn't human.

Marks backed away from the terminal.

"That wasn't just a patient," he said. "That was a conduit."

Siya's pulse quickened.

"They weren't treating her," she said. "They were using her."

Echo Ward – Observation Room – 1:27 PM

The hallway opened into what had once been a monitoring station. Thick one-way glass that overlooked a sealed chamber beyond, like an aquarium, but what had been inside was no fish.

On the glass, someone had written a message in red grease pencil: Do not listen to the song.

The message had been smeared, as if someone tried to erase it and gave up halfway.

Inside the room beyond, a single restraint chair sat in the center of a soundproof cell. Thick leather straps hung loose, speakers were embedded in the walls and the floor was scuffed, dented, like someone had fought to get out.

Siya stared through the glass, and something stared back.

For just a heartbeat, she saw a shape sitting in the chair, tall, wrong, faceless. Then it was gone.

Marks cursed softly. "Tell me you saw that."

Siya nodded once, jaw tight. "We're not alone down here."

Echo Ward – Patient Records Room – 1:39 PM

They moved fast now, adrenaline setting a rhythm. The hospital above felt miles away. Down here, time felt old and wounded.

Siya sifted through rusted file drawers. Most folders were faded beyond recognition, but one was still crisp, recent.

She opened it.

Patient: A. Ndlovu (Echo-3)

Date of Transfer: Unknown

Status: ACTIVE

Location: Redacted

Under treatment notes: Increased resistance to auditory stimuli. Subject no longer sedated. Responds directly to unspoken inquiries. Shared hallucinations reported among staff.

Protocol BETA-LISTEN engaged. Staff instructed to monitor their own thoughts post-interaction. 'Echo contamination' risk remains high.

Marks skimmed the page and whistled under his breath. "What the hell is Beta-Listen?"

Siya didn't answer. She was focused on a torn Polaroid clipped to the file.

It showed a group of patients standing in the hallway. All staring directly at the camera.

All except one. At the far edge, a girl with her back turned. Her hair was short, with the back of her gown was labeled E-3.

Siya flipped the photo over and in thick black ink were written the words: She's still singing.

Echo Ward – Security Hallway – 1:58 PM

They were almost ready to leave when the humming began again.

At first it came from the speakers, then from the walls and then from inside them.

A low, dissonant harmony, like an orchestra tuning before a funeral.

Marks clutched his ears. "Make it stop."

Siya gritted her teeth and focused. The hum wasn't random, it was a pattern, the same signal from the ECG. It was Asanda.

Siya ran back to the terminal, fingers flying across the keyboard. She activated the most recent session file and a real-time audio feed opened.

Someone was still hooked to the system and still transmitting, but it was not Asanda, it was someone else.

A raspy, terrified male voice filtered through the speakers. "It's watching me. It wears her face. It sings through her mouth. You can't stop it. You can't-"

A wet, static crunch cut off the recording, the sudden silence, but not for long. There was something new, a whisper, clear and directed. "Hello, Siya."

The voice had come from nowhere, and everywhere.

Marks was already backing toward the elevator. "We need to go. Now."

But Siya wasn't done.

She pushed through another door, deeper into the abandoned wing, drawn by something more than curiosity. The further in they went, the colder it became. Not just temperature but presence. Like the hallway was holding its breath.

The walls were covered in soundproofing foam, but sections had been clawed through. Padded doors bore gouges. One door at the end was still locked tight, its observation slit stained with something dark.

Siya approached slowly. Inside, something moved.

"Marks," she said.

He came up behind her, weapon drawn now.

She opened the observation hatch. At first, they saw nothing, then - eyes.

In the far corner a male figure sat with his knees pulled up to his chest.

He looked up as if hearing her approach through layers of concrete.

His face was gaunt. Eyes bloodshot. A patient bracelet clung to a bone-thin wrist.

Name: D. Beukes

Marks whispered, "He's alive?"

The man suddenly jolted upright, pressing his face to the slot.

"You're not real," he hissed. "You're not her."

Siya leaned closer. "Who are you?"

His voice was ragged, frayed like broken wire. "I was an intern. Before the silence. Before she sang."

"Before who sang?" Siya asked, her heart pounding.

Beukes's lips quivered. "She sings from the inside now. Through the walls. Through us. We opened something, and it won't shut."

"Who opened it?" Marks asked.

But the man didn't hear him. He was staring past them now, into the hallway, eyes wide.

"They're coming," he whispered. "You listened too long. You heard her voice."

Siya turned and the speakers above them popped and then that tone again, with a steady, rising frequency.

Blood began to drip from Beukes's nose. He screamed, grabbing his ears, convulsing.

"GET OUT!" he shrieked. "BEFORE THEY FIND YOU!"

Siya grabbed Marks and they ran.

Echo Ward – Service Elevator – 2:14 PM

The lift shuddered as it rose, groaning like something trying to resist the ascent.

Siya clutched the Threnody file. Her hands wouldn't stop shaking.

Marks leaned against the wall, breathing hard. "That was... that was not schizophrenia. That wasn't psychosis. That was a broadcast. A signal."

Siya nodded. "And it's using my sister's voice."

Marks looked at her. "You think she's alive?"

"I know she is."

The elevator reached the main floor.

As the doors slid open, both detectives froze. The lights on this floor were off.

Emergency power only. And from somewhere, deep in the hallways ahead, the hum had followed them, that soft, constant hum, that was buried beneath the silence like a thread of infection. It was no longer confined to Echo Ward. It had followed them up, bleeding into the rest of the hospital.

Marks clicked on his flashlight. The beam trembled slightly in his grip.

"Did we bring it with us?" he asked.

Siya shook her head. "It was already here."

They made their way through the dim halls, each shadow twitching at the edge of vision. Siya's mind buzzed. The Threnody file was heavier in her hands now, as if knowing the secrets it carried had made her a target.

Then they heard a noise, this time it was not the hum, but a weak, human voice from around the corner near the stairwell.

Siya raised her sidearm, advancing carefully. "Who's there?"

No answer.

They turned the corner.

Someone lay crumpled against the wall, an orderly, based on the uniform, with blood pooled beneath him, seeping from his ears and nostrils. His eyes twitched rapidly beneath half-lidded eyes. He was still alive but barely.

Siya knelt. "Hey! Can you hear me?"

The man's lips moved.

She leaned closer.

His voice was dry as paper. "Don't follow the song..."

His body convulsed.

Then stilled.

A sharp tone filled the air, a sudden burst of feedback from the ceiling speakers, whispers, not just from the speakers, from everywhere. The walls. The vents. The lights. The very floor. Hundreds of overlapping voices, speaking in half-formed syllables.

Marks yelled, covering his ears. "We have to go!"

Siya pulled him down the corridor, toward the emergency exit stairwell. The whispers chased them, growing louder, more intentional.

One word repeated again and again in the chaos: "Return."

They burst through the stairwell door and climbed fast. Each step felt heavier. Like gravity didn't quite agree with them anymore.

When they reached the ground floor, the lights were back to normal and the reception buzzed with life.

Doctors moved. Nurses charted. A security guard sipped coffee behind his desk. Everything looked normal. Too normal.

Siya paused at the threshold. "Did we just hallucinate all of that?"

Marks turned to her. "Then how do you explain this?"

He lifted his shirt slightly.

His chest bore a mark, not a bruise, and not blood, it was a burned-in symbol just beneath his collarbone, a spiral of concentric lines.

Siya pulled out the photo from Echo Ward, the one of the patients.

In the bottom corner, scrawled faintly behind the group was the same identical spiral.

Siya looked up at the ceiling speakers overhead. The hum was gone now, but it was waiting and watching, because it had her name.

The hum had faded from her ears, but the silence it left behind was heavier than any sound. Siya Ndlovu leaned against the hood of her car, staring out at the sweep of Cape Town's cityscape.

Below, the world went on, sirens howled in the distance, buses grumbled along the Main Road, and the hospital staff bustled in and out of the emergency wing. Everything above ground remained alive, and yet, Siya could feel it.

She could feel that whatever lived in Echo Ward hadn't stayed behind.

Marks stood a few steps away, his arms folded tight across his chest. His usually sharp demeanor was dulled now, haunted. She knew he was trying to rationalize it, chalk it all up to trauma, or some experimental hallucinogen wafting through the vents, but the mark burned on his chest said otherwise.

Siya pulled out the photo again, the one from Echo Ward. Five patients staring straight into the camera. One with her back turned. The spiral inked on the wall behind them like a brand. Her fingers traced the spiral's curve for the hundredth time, hypnotized by how it always led inward, never out.

Marks broke the silence. "What do you think it means?"

Siya didn't look up. "A warning."

"A warning?"

"Or a key. Either way, someone didn't want us to forget it."

She showed him the Polaroid. "Look here." She pointed to the barely visible smudge of ink.

It was a sspiral within spiral. "It was on the wall behind her. And now it's on you."

Marks pulled his shirt collar down again to look. The spiral, faint but undeniable, was burned into his skin like a brand. He winced as he touched it. "It stings now."

"It wasn't just in the photo," Siya said. "It was drawn everywhere in Echo. Scratched into the paint. Written in blood on the underside of a drawer. It's a pattern, Marks. Someone was trying to document it, or contain it."

Marks dropped his hand. "And what about that voice in the speakers? What about the guy screaming in that locked room?"

Siya looked up at the grey sky. "I think he was already gone. Just echoing."

Marks didn't argue. He just pulled a cigarette from his jacket and lit it with shaking fingers.

"What now?" he asked. "We go back down?"

"No. We go deeper," Siya said. "There's someone still alive. Someone who knew Asanda. He was transferred out of Valkenberg in 2021. His name came up in the Threnody file. And he's still in the psych wing. Ward C room 3."

Marks gave her a sidelong glance. "You're serious? You want to talk to another one of them?"

Siya pocketed the photo. "I want answers."

Back in the Psych Evaluation Wing, it was just a little after 4 PM

Room 3 had the dull antiseptic smell of institutional decay, cleaned often but never fully clean. The lights overhead flickered faintly, like everything else in the hospital was running on backup power even though the generator hadn't tripped.

Patient 1642. Jacus Meyer. Transferred from Valkenberg after a failed suicide attempt. Diagnosed with late-stage paranoid schizophrenia, though the file notes were inconsistent. Some labeled him as delusional and unstable; others described him as "controlled," "nonverbal but compliant," and strangely "reverent."

Siya stood in the doorway, observing him before stepping in.

Jacus sat on the floor, cross-legged, rocking gently. His arms were thin, bones jutting out beneath translucent skin. He wore no restraints, no IVs. Just a loose hospital gown and an expression of absolute stillness.

But the walls, they were covered. Floor to ceiling. Every surface was lined with spirals. Some were drawn in ink. Others gouged into the paint with fingernails or the edge of a spoon. They varied in size, in shape, but never in design. Each spiral began from the outer edge and wound inward, leading to a central point.

The longer Siya looked, the more they seemed to move. She blinked trying to refocus.

Jacus turned his head, slowly, like he hadn't noticed them until that moment.

His eyes were wrong, too calm, and too clear.

"Jacus?" she said gently.

He didn't respond.

Marks stepped in, staying by the door. "Not talking?"

"He hasn't spoken in over three years," Siya murmured.

She knelt beside Jacus, pulled the Polaroid from her coat, and placed it gently in front of him.

"Do you know her?"

Jacus's eyes flicked down to the image, then to Siya. He extended a hand, frail and trembling, and pointed, not at the girl, at the spiral in the corner of the image, then, almost imperceptibly, his mouth opened and he began to hum.

The hum started soft. Barely audible. Just a tremor of sound from Jacus's throat, low, throaty, and continuous, then it grew, not in volume, but in density.

Siya felt it more than she heard it. Like it was pressing in through her skull, bypassing her ears. A resonance. A vibration. Her stomach turned with a creeping nausea.

Marks flinched and backed toward the door. "Siya, I don't like this."

She couldn't respond. She was locked in place.

The humming shifted and it became layered. Beneath it, there were faint harmonics, like other voices were joining in, humming just below hearing range. Hundreds of them, were singing the same note.

The air seemed to warp.

Siya grabbed the metal bedframe to ground herself. "Stop," she whispered. "Please, stop."

Jacus opened his eyes wide, then he spoke.

"She walked through." His voice was raw, like dry paper scraping against itself, but it was clear.

Siya's breath caught.

Jacus turned his face toward her. "She didn't come back."

Siya leaned forward. "Who? Who didn't come back?"

Jacus's lips trembled. "The twin. She sang for them. They opened the way. The door swallowed her."

"Asanda?"

Jacus blinked. "She remembered too much."

Marks stepped back in, gripping his gun, though he clearly didn't know why. "Siya, we need to move. This place is wrong."

But Siya couldn't tear her eyes away. Jacus wasn't finished.

"She left a part of herself behind. That's what they follow. That's what calls them."

"Calls what?" Siya asked.

Jacus tilted his head. Then reached out slowly, grabbing the corner of the photograph with frail fingers and flipped it over. On the back, in pencil, he drew a single symbol:

A rectangle, with jagged lines across the edges and a door, and below it, one word: "Threshold."

Then another word, shakier: "Song."

And then: "Gate."

Siya stared at it, heart racing. "This... this is what Project Threnody was trying to open."

Jacus gave a slow, jerking nod.

Marks frowned. "And you're saying Asanda went through this gate?"

Jacus's hands began to tremble violently. He curled into himself, pulling at the collar of his gown. Thrusting his palm towards them.

Burned into his skin, red and cracked, was a door. The same one he'd drawn.

Siya staggered back. "He's branded."

Marks grabbed her arm. "That's it. We're done here."

But Jacus suddenly looked up and shrieked. Not in fear. In warning. "They're coming-"

The lights burst overhead,alarms wailed and somewhere down the corridor, a door slammed open with inhumane force.

Jacus began screaming, tearing at the walls, ripping spiral after spiral into the paint with his nails. The humming returned, louder now, flooding the room like a rising tide.

Siya and Marks ran to the service corridor, on the lower east wing and continued running until they hit a locked security door.

Marks slammed his fist on the control panel. "Override it!"

Siya hacked into the keypad, fingers flying. "This section's not connected to the main power, it's manual lockout only."

The humming followed them. Not as sound now, but in the walls. In the pressure of the air. The temperature dropped sharply.

Siya got the door open just as the lights behind them flickered red.

They slammed the door shut and silence returned, but not for long. On the other side there was a soft knock tap, not one but two.

Then a voice whispered, low and guttural:

"Return. Return. Return."

Siya backed away, breath shallow.

Marks pulled her down the hallway.

"This place is infected," he said. "It's not just Jacus. Something inside the hospital is leaking out."

Siya held up the photo. "It's already out, and whatever Asanda left behind, it's calling them back."

Marks stared at her.

Then her phone buzzed. An unknown number.

One new text: You were warned.

Followed by another: She sings again.

Siya's hands trembled as she looked at Marks, then down the hallway.

There was only one path left. They had to go back to where it started.

Ut was 5 PM by now Siya and Marks would be clo king out, bt now they were headed back to the basement archives.

They moved quickly. No more than whispers between them. Siya led them through back corridors, down a maintenance stairwell, and into the sublevel storage rooms of Groote Schuur's east wing-long-abandoned file archives sealed since before the hospital went digital.

Dust coated everything. It muffled their footsteps. Even the buzzing fluorescent lights overhead seemed to avoid this part of the building. It was as if the hospital forgot this place existed.

But Siya remembered, this was where she'd first seen Dr. Louw take files from the Valkenberg patient transfer program, when she was still a junior detective working a missing persons case that had nearly cost her her career.

That case was about a nurse who vanished mid-shift.

She now suspected that that woman had been an early test subject of Project Threnody.

Marks glanced around, his hand near his holster. "Why are we here again?"

"Because this wing isn't on the hospital's official floorplan," Siya said, brushing aside cobwebs from a file drawer. "Which means it's not under surveillance."

"And?"

"And that means it's where Louw hid the originals."

She yanked open a rusted drawer. Inside, folders had melted together with age and neglect, but tucked behind the front panel was a manila envelope, newer than the rest, she slid it free and opened it carefully.

Inside the file - Contents:

A patient transfer form with the Valkenberg crest.

A psychiatric chart marked "CONFIDENTIAL: THRENODY."

A black-and-white security photo dated 2019.

And a spiral, drawn in pencil, copied again and again in the margins.

But it wasn't just the symbol that made her stop, it was the face in the photo, the face of a girl in a hospital gown standing in a white room.

"Asanda," she murmured.

She was older than Siya remembered. Paler. Her eyes were bloodshot, and her hair had been shaved unevenly, but it was her.

Behind her, the spiral was painted across the floor in what looked like rust or blood.

Marks leaned in. "Jesus..."

Siya's voice broke. "She was a patient."

"And not just any patient." He pointed to a handwritten note in the file's margin.

Phase III subject. Memory displacement successful. Entity containment achieved, partial. Recommend isolation. Gate resonance unstable.

He looked at Siya. "Your sister was the gate."

They sat in silence for a few moments. The low buzz of electricity flickered overhead, barely holding.

Siya pieced together what she could.

Phase I-whatever it had been-started in Valkenberg. Early attempts. Echo Ward was part of it.

Phase II-experiments in containment, sound frequency, and memory suppression.

Phase III-Asanda. A living conduit. A vessel for something that had crossed over.

Marks exhaled slowly. "This isn't about mental illness. They were experimenting with the limits of consciousness."

Siya nodded. "Opening minds to something else."

Marks looked grim. "And now that something is coming back."

Then Siya saw it. Tucked in the corner of the file: A map. A map to Groote Schuur's lower tunnels. One room was circled in red. "E.W. Chamber – Locked Access. Former Isolation Suite."

She tapped the page. "Echo Ward's buried here."

Marks blinked. "Wait. You mean Echo isn't just a wing-"

"-It's a system. It runs beneath the hospital. Groote Schuur and Valkenberg are connected by tunnels, and Echo sits right in between them."

Marks stared. "That's how the files moved. How they transferred patients off the books."

Siya folded the file and stood. "We're not done yet. We find that chamber. Tonight."

Marks stood too. "You really want to go under the hospital? After what just chased us?"

She looked him dead in the eye.

"If my sister's still in there-so am I."
