Chapter XXXVII: The Fick Equation
The rain hasn't stopped.
It bleeds through the night sky like ink, tracing every rooftop, every lamp post, every breath that dares escape into the damp air of London. The Thames murmurs below the fog, its waters moving with the slow patience of something ancient.
Inside King's College, the lights burn dim. The corridors smell of iron and old parchment. Theo paces along the marble floor, his reflection split by the puddles that collect beneath the windowpanes. He looks restless—haunted.
Nathaniel sits silently at the long table, a dozen books sprawled open, their margins filled with sketches, equations, and fragments of scripture. His eyes, dark and focused, scan every page like they might tear through history itself. The rain taps gently against the window behind him, the rhythm steady—too steady.
Theo slams another book shut.
"Every record ends the same way," he mutters. "Adolf van Giovanni—composer, traveler, patron of the arts. And then—poof—disappears after 1945. No death, no burial, nothing. He just vanished."
Nathaniel doesn't look up. "People like him don't vanish. They hide."
Theo exhales sharply, running a hand through his hair. "Hide? From what? He's already haunting us."
Nathaniel finally looks up. His gaze is sharp, shadowed by exhaustion. "That's what I intend to find out."
Theo sits across from him again, flipping through another worn-out journal. The paper smells like dust and candle smoke. Each page carries faint drawings—sigils, crests, and family seals. Theo squints at one sketch: an emblem of a serpent biting its own tail, encircling a rose.
"Hey," Theo says. "You've seen this before, haven't you?"
Nathaniel glances over. His pulse quickens. "That's... the Gravenholt insignia."
Theo freezes. "You mean—Eris's family?"
Nathaniel nods slowly. "Yes. And if that's on Adolf's personal ledger..."
Theo stares down at the emblem again, tracing the lines with his finger. "Then he's one of them."
For a moment, neither speaks. The air thickens with the weight of revelation.
Nathaniel turns another page. A series of faded letters spill across the parchment, written in German, then Latin. The handwriting is elegant, serpentine. At the bottom, a signature stands out: A. van Giovanni.
Theo whispers, "You think he was working with them?"
Nathaniel reads quietly:
"The symphony of blood and light shall rise again. The painter's legacy must live through the vessels of night."
He frowns. "Not just working with them... he was family."
Theo's chair screeches back. "Wait—what?"
Nathaniel's eyes narrow, voice low. "The van Giovannis are a cadet branch. The Gravenholts sent them to Austria centuries ago—to preserve their 'artistic' bloodline. And there's something else here."
He pulls out another sheet, the ink nearly erased by time. The seal at the bottom bears the faint outline of a swastika—a remnant of a forgotten allegiance.
Theo goes pale. "You're saying... he's related to that painter? The Austrian one?"
Nathaniel nods grimly. "The same blood. The same obsession with purity, perfection, control. That's why his power feels... wrong."
Theo takes a step back, voice shaking. "You're telling me Adolf van Giovanni is literally the blood descendant of the Austrian Painter and the Gravenholts? That's—"
"—the reason he's dangerous," Nathaniel finishes. "He's a creature built from obsession itself."
Outside, thunder cracks across the sky like the earth splitting open.
Hours pass. The library turns into a battlefield of books and candlelight. Notes litter the floor; ink stains their fingers. Theo types furiously on an old laptop, cross-referencing genealogy records, museum archives, and war documents.
Nathaniel paces slowly behind him. "Cross-check the art pieces he sponsored. Vienna, 1938 to 1943."
Theo clicks through grainy photographs. "Here. A gallery called Der Letzte Klang—'The Last Sound.' Sponsored by Adolf van Giovanni. Every artist who performed there vanished within a year."
Nathaniel leans closer, eyes scanning the images. "Look at that painting in the corner. The one with the crimson sky."
Theo zooms in. "It's titled Resonanz. By Erich Gravenholt."
Nathaniel's chest tightens. "Her ancestor."
The painting is unsettling: a man with half his face human, half shadow, standing before a burning cathedral. Behind him, dozens of violins hang suspended by invisible strings.
Theo stares. "It's like he painted you."
Nathaniel's reflection flickers in the laptop screen, faintly distorted by the glow. His expression is unreadable. "Maybe he painted what I'd become."
Theo glances at him. "You're not like them."
Nathaniel doesn't respond immediately. He gazes out the window where the rain streaks like veins across the glass. "Not yet."
The silence stretches between them until Theo finally breaks it.
"You ever feel like... he's watching us?"
Nathaniel turns slowly. "Adolf?"
Theo nods. "Every time I close my eyes, I hear that damn violin. Like it's under my skin."
Nathaniel leans against the desk, arms crossed. "That's how he marks his prey. Through resonance. It lingers."
Theo laughs nervously. "Yeah, well, tell him to pick another hobby. I'm running out of sleep."
Nathaniel studies him for a long moment, then says quietly, "You're afraid."
Theo smirks, but his voice trembles. "Of course I am. You saw what he did last time. He bent light like it was a toy. He could've killed us if he wanted to."
Nathaniel's tone remains steady. "Then we learn why he didn't."
Theo looks up sharply. "You want to face him?"
Nathaniel meets his gaze, eyes calm but burning. "I want to understand his weakness. And for that, we need to confront him."
Theo throws his arms up. "You're insane. He's not human, Nate."
Nathaniel tilts his head. "Neither am I."
The words hang in the air like a verdict.
Theo opens his mouth, then closes it again. The rain outside intensifies, as if the sky itself is listening.
Nathaniel pulls a small notebook from his coat. The cover is blackened, burned at the edges. "This was left in Eris's study the night everything fell apart."
Theo hesitates before taking it. The first page is a family chart—names spanning centuries, written in elegant script. Gravenholt. Van Giovanni. Reiss. Van Helsburg.
Theo reads aloud. "It's a family tree... but the branches keep looping back. Like they're breeding within themselves."
Nathaniel nods. "That's how they preserve the curse. Every generation, they attempt to recreate the 'perfect resonance.' But it always fails."
Theo flips another page. There's a portrait sketch of a man who looks eerily like Adolf, holding a violin. Beneath it, the name: Alois Van Giovanni, 1888.
Theo frowns. "Wait a second. Alois. As in—"
"Yes," Nathaniel interrupts softly. "The father of him."
Theo's face pales. "The Austrian Painter."
Nathaniel continues, "They used the arts as a veil. Music, painting, architecture—all expressions of the same madness. Each one trying to perfect the balance between creation and destruction."
Theo looks up, unsettled. "And now Adolf's trying to finish it."
Nathaniel nods. "He calls it the Symphony of Rebirth. A world tuned to his own frequency."
A crash interrupts them—a window shattering somewhere in the hall. Both men freeze.
Theo whispers, "Did you hear that?"
Nathaniel's hand instinctively moves to the silver dagger on the desk. "Stay behind me."
The wind howls through the corridor, bringing with it the faint sound of strings—delicate, distant, haunting.
Theo grips the edge of the table. "He's here again, isn't he?"
Nathaniel's eyes narrow. "No. This is different."
They move carefully through the dark hallway. Each footstep echoes like a gunshot. The smell of rain and ozone fills the air. At the far end of the corridor, the moonlight bleeds through a cracked skylight. Something glimmers in the puddle below—a single violin string, coiled and wet.
Theo kneels to touch it. "It's warm."
Nathaniel crouches beside him, voice low. "He's marking us again. Not attacking. Just reminding us he's watching."
Theo looks up. "Why?"
Nathaniel stares at the string. "Because he knows we're close."
Back in the study room, Nathaniel spreads the notebook, the letters, and the emblem across the table. The candle flames waver violently as thunder rumbles overhead.
Theo sighs. "So what now? We can't exactly put 'possible immortal Nazi vampire' into the college archives."
Nathaniel gives a humorless smile. "No. But we can expose the bloodline's logic. Every curse has a pattern. Every monster has a rhythm."
Theo frowns. "You sound like him."
Nathaniel looks up, eyes calm but fierce. "That's the point."
He points to a map pinned on the wall—London's layout overlaid with crimson lines. "Look. Each of Adolf's appearances—Hyde Park, Westminster, King's Cross—they form a pattern. A sigil. Something ritualistic."
Theo leans in. "He's conducting something..."
"Exactly," Nathaniel says. "He's tuning the city. Using its resonance—its energy, its echoes—to prepare for something larger."
Theo's voice drops. "The Symphony."
Nathaniel nods. "He's almost ready. But he needs a catalyst. A bloodline strong enough to bridge both worlds."
Theo's eyes widen. "You mean—"
"Yes." Nathaniel's voice is a whisper. "Me."
Theo slams his fist on the desk. "Then we have to end this before he uses you!"
Nathaniel shakes his head. "If we move too soon, he'll vanish again. We have to understand his key. Every composer hides a flaw in his melody."
Theo glares. "And what if that flaw is you?"
Nathaniel's jaw tightens. "Then I'll use it."
Thunder rolls again, shaking the old windows. The candles flicker out, one by one. For a moment, the only light comes from Theo's faint glow—a golden pulse from the markings on his palms.
Theo exhales. "You're not alone in this, Nate. I'm with you. Always."
Nathaniel glances at him, the corners of his mouth softening. "I know."
In another place—an abandoned opera house hidden deep within the fog—Adolf van Giovanni stands before a grand mirror. His reflection smiles faintly, though his lips do not move.
"The boy learns too quickly," the reflection whispers.
Adolf tilts his head. "Good. A dull adversary makes a dull symphony."
He drags his bow across the violin strings once, and the mirror ripples like water. Through its surface, faint images flicker—Nathaniel studying, Theo pacing, the seal of the Gravenholts shining in candlelight.
Adolf's smile widens. "Let them uncover the truth. The more they see, the closer they come to despair."
He lifts his violin. "After all... every masterpiece begins with suffering."
The melody he plays this time is softer, more intimate—a song that travels across the fog, reaching the heart of London like a whisper through the rain.
Nathaniel jerks upright. His heart thunders in sync with that faint sound. Theo looks at him from across the table, startled.
"Nate? What's wrong?"
Nathaniel grips his chest, feeling the pulse of the curse react. "He's calling."
Theo's glow brightens instinctively. "Then ignore him."
Nathaniel shakes his head. "No. This isn't a trap. It's a signal."
Theo blinks. "A signal for what?"
Nathaniel's gaze sharpens. "He's challenging me. And I'm done running."
Theo stares at him, uncertain. "You're planning something, aren't you?"
Nathaniel turns back toward the rain-streaked window. "Yes. But this time... I won't fight him in the dark."
He gathers the scattered notes, sliding the burned notebook into his coat. "We finish the equation tonight. We turn his resonance against him."
Theo looks alarmed but follows as Nathaniel strides toward the door. "Where are we going?"
"To the place where his melody began," Nathaniel says. "The old theater near the Thames."
Theo hesitates only for a heartbeat before nodding. "Then let's end this symphony."
The night stretches on. The fog thickens. Every streetlamp flickers like dying stars as they walk through the empty streets. The rain softens, almost reverent.
Theo glances sideways at Nathaniel. "You ever think this all started with a girl and a bridge?"
Nathaniel gives a faint smile. "Every tragedy begins with something simple."
Theo sighs. "And every hero's story starts with a choice."
Nathaniel's eyes gleam faintly crimson in the dark. "Then I've already made mine."
As they reach the theater steps, the violin music grows louder, bleeding through the mist. The old building looms like a mausoleum—its doors half-rotted, its chandeliers flickering with unnatural light.
Theo shivers. "Feels like walking into a nightmare."
Nathaniel's hand tightens around his dagger. "Then let's wake up."
They push open the doors.
The sound that greets them isn't just music—it's a pulse, a heartbeat made of strings and sorrow. The walls hum. The air vibrates.
Nathaniel steps forward, his eyes narrowing. "This is it."
Theo whispers, "He's turning the city into an instrument."
Nathaniel nods. "Then we play our part."
As they descend into the darkness of the theater, lightning flashes outside, casting their shadows tall against the ruined walls.
The symphony of blood and light has begun its final movement.
And for the first time since his curse began, Nathaniel Cross feels no fear—only the steady rhythm of purpose, echoing through his veins like destiny itself.
