Chapter LIV: The Mimic Conjecture
Morning bleeds through the fog like light filtered through bruised glass.
The London skyline rises beneath it, half-shrouded, half-awake. Cobblestones glisten with last night's rain, and puddles catch warped reflections of passing carriages, headlights, and sleep-deprived students trudging toward the university gates.
For Nathaniel Cross, the day feels too calm — the kind of calm that follows a storm, or worse, the kind that comes before one.
He adjusts the cuff of his coat, the fabric still damp from the rainstorm that had greeted them after the café incident. His bandaged hand aches faintly under the glove, but he ignores it. He's used to wounds that won't heal fast enough — especially the ones that don't bleed red.
Theo walks beside him, sipping from a thermos of black coffee. "You look like you haven't slept in years, mate."
"I didn't," Nathaniel replies.
"Not surprising," Kingsley mutters behind them, flipping through his notes. "You nearly turned a café into a haunted opera house. Even the espresso machine screamed."
Theo smirks. "It screamed because you broke it."
"Semantics."
Pauline joins them at the steps of the university library, her coat a sharp contrast of ivory against the dull gray morning. "Let's stay focused. The mimic didn't just vanish — it retreated. There's a difference."
Nathaniel nods, pushing open the heavy oak doors. The smell of old parchment and candle wax greets them, a ghost of centuries past whispering through the corridors. The library is massive — gothic arches climbing toward stained glass skylights, each depicting scenes of saints and angels that seem to watch whoever enters.
Edison's already waiting at one of the long tables, several dusty tomes and a portable laptop spread before him. "You're late," he says, without looking up.
"We brought caffeine," Theo says, tossing him a can.
Edison catches it. "Forgiven."
Nathaniel takes a seat at the head of the table. "All right. We need everything we can find about mimics — myth, folklore, psychological parallels. Anything that connects human reflection and manifestation."
Pauline slides a thick, cracked-spined volume toward him. "Found this in the restricted archives. The Codex Umbrae. Mentions a few entities that use mirrors as conduits."
Nathaniel flips it open carefully, eyes tracing the faded ink. The sketches are grotesque — humanoid forms with faces half-formed, eyes hollow but watching.
He reads aloud softly, voice echoing in the quiet hall:
'The Mimic, known among scholars as Speculum Maledictum, is a shade born from grief and remembrance. It is neither ghost nor demon, but an echo given hunger. It thrives where reflections multiply — glass, water, or polished metal. It sings when it feeds, and plays music from memory. Those who hear it often mistake the melody for comfort... until it begins to hum back.'
Theo shivers. "Lovely. A stalker with taste in classical music."
Pauline leans closer. "There's more." She points to a passage near the margin. "It says it avoids sunlight and mirrors held by living beings. Something about self-recognition burning it."
Edison raises a brow. "So it hates being reminded of what it is."
Kingsley nods thoughtfully. "Then that's our weapon — reflection itself."
Nathaniel closes the book. "Then we prepare mirrors. Hand-held, silver-backed, no glass fractures. And sunlight — controlled exposure."
Theo frowns. "You're suggesting we walk around like vampire hunters from the 1800s?"
"Precisely."
Pauline pulls another book from the stack — this one modern, thin, labeled Urban Legends of London. "There's a section here on something called The Mirror Concerto."
Edison perks up. "Concerto?"
She reads:
'An old tale says that when one hears a piano or violin playing softly in an empty room, do not seek the source. For the player is not living, but an imitation of one — a being that learns the sound of sorrow and plays it back. They say those who follow the melody are never seen again, except in reflections that smile too late.'
The room chills.
Theo mutters, "And we're... going to find it, right?"
Nathaniel looks at the others. "That's exactly what we're going to do."
They gather at Nathaniel's flat — a modest, book-crammed corner near Bloomsbury. Rain traces veins across the windows while Edison sets up portable scanners, Theo calibrates microphones, and Pauline polishes a silver hand mirror under the lamplight.
Kingsley stands by the table, slicing tape to seal vials of preserved blood. "You know," he says, "normal engineering students build bridges, not vampire traps."
Theo grins. "Speak for yourself. This is the most practical project I've ever done."
Pauline glances at Nathaniel, who's standing near the window, watching the city beyond the rain. His reflection in the glass looks pale, tired, but alive. "You sure about this?" she asks quietly.
"I'm sure about one thing," he says. "Running won't help. Not anymore."
Her tone softens. "This isn't just about Eris anymore, is it?"
Nathaniel doesn't answer. His eyes flicker toward the city lights reflected in the window. For a moment, one of them blinks — not a lamp, but an eye.
He exhales slowly. "No. It's about understanding what she left behind."
Fog rolls through the narrow streets like breath from the city's lungs. The group moves quietly, their reflections ghosting beside them in the wet glass of shop windows. Each carries a small hand mirror tucked into their jackets, gleaming like hidden weapons.
They arrive at the Camden underpass — the same place Pauline had mentioned, where reports of classical humming had surfaced. The air smells of rust and stone, faintly metallic.
Nathaniel signals the others. "Positions."
Edison and Kingsley set up motion detectors at both tunnel ends. Theo mans the laptop, screens glowing in blue light. Pauline stands beside Nathaniel, mirror in hand.
For a while, only the dripping water breaks the silence. Then — faintly — a sound begins.
Piano keys. Slow. Measured.
A haunting melody unfurls through the tunnel — deliberate, elegant, cruelly beautiful.
Theo whispers, "That's not a recording."
Pauline tightens her grip on the mirror. "It's here."
Nathaniel listens closely. The piece is familiar — Clair de Lune, but fractured, its notes slightly off-tempo, as if played by someone remembering the song rather than performing it.
The shadows near the far wall ripple.
Something steps out.
It's the Shalltear cosplayer again — lace white, eyes faintly glowing, lips parted in that impossible smile.
Nathaniel steps forward, calm, deliberate. "Who are you?"
The figure tilts her head. "You know me already."
"No," Nathaniel says, voice low but steady. "I knew Eris. You're not her."
The mimic's smile falters — just slightly. "Eris... yes. I remember that name."
Pauline swallows. "Remember?"
"I am what remains," the mimic whispers. "An experiment... a memory given hunger. Born of the Gravenholts' obsession to copy perfection."
The name hits the air like a curse. Kingsley's eyes widen, but Nathaniel lifts a hand, silencing him.
"So you're their creation," Nathaniel says.
"Creation?" The mimic laughs softly — the sound cracks mid-note. "No. Their mistake."
Before anyone can react, she moves.
Faster than thought — a blur of white and crimson. Her hand slashes toward Nathaniel, who blocks with his mirror. The glass flashes with sunlight trapped inside; the mimic hisses, stumbling back, her skin sizzling faintly.
Theo shouts, "It works!"
"Keep the mirrors up!" Pauline yells, raising hers. The mimic flinches again as the reflected light strikes her face.
But then — the melody returns. Louder now, echoing from every direction. The mimic's laughter intertwines with it.
"You think reflection hurts me?" she whispers. "It reminds me I exist."
The mirrors tremble in their hands, vibrating as if struck by invisible strings. Cracks begin to form.
Edison curses. "She's overloading the resonance frequency!"
"Then break the rhythm!" Nathaniel commands. "Interrupt the music!"
Theo slams the laptop keys, generating a counterwave — static noise bursts through the tunnel, clashing against the mimic's melody. The air ripples, distorting like heat on glass.
The mimic screeches, clutching her head. "STOP—"
Nathaniel lunges forward, slamming his mirror against her chest. "Not until you answer me! Why mimic Eris? Why her face?"
The mimic's eyes blaze red. "Because she was the first who looked at the void... and called it beautiful."
Nathaniel freezes.
For a second, the world around him tilts — flashes of memory, of Eris standing under the moonlight, her smile softer than her fangs, her voice whispering "Don't fear what you don't understand."
The mimic takes advantage of his hesitation, thrusting him backward. He crashes against the wall, the mirror shattering.
"Nathaniel!" Pauline screams.
He grits his teeth, pushing himself up. Blood seeps from his temple. He looks at the mimic, breathing hard. "You're not her," he says again, but this time his voice carries something else — grief, tempered by rage.
The mimic grins, her form flickering like a dying flame. "Maybe not. But I remember her hunger... and yours."
She lunges again — claws outstretched — but this time, Nathaniel's ready.
He grabs one of the broken shards of his mirror, letting the moonlight catch it. The reflection flares — pure sunlight trapped in the sliver of glass. He drives it forward.
The mimic screams, the sound echoing like shattering crystal. Her body disintegrates into ribbons of light and shadow, scattering across the tunnel walls, absorbed into the reflections.
Then — silence.
Only the drip of water. The echo of the last piano note fading.
Pauline runs to Nathaniel's side. "Are you all right?"
He nods weakly. "Yeah... but she's not gone. Just dispersed."
Edison checks the monitors. "The signals spiked — then vanished. She's moved through the reflection field again."
Kingsley kneels beside a puddle — faint traces of crimson light swirl within it. "She's splitting herself. Multiplying."
Nathaniel wipes the blood from his face. "Then we hunt every reflection. Every echo."
Theo looks uneasy. "That's a lifetime's work, Nate."
"Then it's a lifetime I'll spend," he says quietly.
He picks up a fragment of the shattered mirror, holding it to the light. His reflection stares back — fractured, uncertain. For a moment, another face flickers behind it: Eris. Smiling.
Pauline notices. "Nathaniel?"
He closes his hand around the shard, ignoring the cut it leaves. "Let's move. We regroup at dawn."
As they leave the tunnel, the rain begins again — heavy, rhythmic, almost melodic.
Behind them, in the puddle they'd left undisturbed, a faint image flickers. The Shalltear cosplayer — kneeling, smiling faintly, humming Clair de Lune once more.
Her reflection winks before fading.
The hunt isn't over.
It has just begun.
Nathaniel walks ahead of the group, the city's lights reflected in his wet hair and weary eyes. Pauline keeps close behind, silent. Theo mutters something about needing a drink. Edison carries the equipment like a man bearing secrets, while Kingsley stares back once, as if half-expecting the mimic to emerge again.
But the night holds. For now.
Nathaniel doesn't look back. He can still hear the faint trace of Eris's voice in the echo of the rain.
And somewhere deep inside him, something — a pulse, a whisper, maybe even hope — stirs once more.
The mirror in his hand glimmers faintly, catching the dying moonlight.
It hums.
