Chapter 1 – The Champagne Mouse

The bass from the sound system did not just vibrate through the floorboards; it crawled up the spiked heels of Cleo’s stilettos and settled deep in her bones. The Golden Cage was entirely too loud, entirely too bright, and reeked of an intoxicating blend of copper, ozone, and Tom Ford cologne.

Cleo balanced the silver tray on her fingertips, letting her shoulders slump just a fraction to perfect the illusion. On the tray sat a single bottle of Dom Pérignon and three crystal flutes, but her target was the discarded, half-empty vial of Vance’s exclusive ‘Golden Vintage’ resting near the elbow of a Russian arms dealer.

She timed her breath with the drop of the heavy EDM track. Three, two, one.

Her ankle intentionally gave out. Cleo let out a pitch-perfect squeak of alarm as the tray tipped. The crystal flutes shattered against the edge of the mahogany table, showering expensive champagne over the velvet upholstery. The arms dealer roared in Russian, leaping back as the liquid splashed his Italian leather shoes.

"Oh my god, I am so, so sorry! I’m so clumsy!" Cleo gasped, dropping immediately to her knees. Her voice was breathy, high-pitched, the exact tone of a terrified, air-headed bottle girl.

She scrambled over the broken glass, ignoring the sharp sting as a shard grazed her knee. Her hands fluttered wildly, grabbing cocktail napkins to dab at the man’s shoes, but her left hand—shielded by the chaos of her own body—moved with the surgical precision of a pickpocket. Her fingers curled around the discarded vial. With a flick of her wrist, the tiny glass tube vanished up the lace sleeve of her uniform.

"Get away from me, you stupid girl," the dealer spat, shoving her shoulder with the toe of his shoe.

Cleo whimpered, keeping her eyes wide and wet as she crawled backward. Below the surface of her panicked facade, her heart rate remained at a steady, icy seventy beats per minute.

While she swept the broken glass into a dustpan, her peripheral vision tracked the room. She was mapping the ecosystem. The two bouncers near the VIP exit rotated every fifteen minutes; they were three minutes away from a shift change. Through the reinforced glass floor in the center of the room, the underground fighting pit was bathed in harsh halogen light.

Then, she found Elara.

Her friend was stationed three booths down, serving a group of Wall Street types. Cleo’s eyes narrowed slightly. Elara’s posture was rigid, her smile fixed and plastic. But it was the flush of her skin—an unnatural, glowing pink spreading up her neck—and the glassy dilation of her pupils that made Cleo’s jaw tighten. Vance’s control subject. They were dosing the girls just to measure the ambient effects of whatever they were pumping into the fighters downstairs. Cleo analyzed Elara’s micro-expressions. Muscle tremors in the left hand. Elevated respiratory rate. The lab beneath the club was adjusting the formula tonight; Elara was deteriorating faster than yesterday.

"Careful there, Champagne Mouse."

A heavy, clammy hand clamped down on the top of Cleo’s head, patting her hair as if she were a particularly slow golden retriever. She froze. The man looming over her was one of the club’s top investors, his breath foul with cigar smoke and stale whiskey. He tossed a crumpled hundred-dollar bill, aiming perfectly so it slid down the deep plunge of her corset.

"Clean it up and scurry along," he sneered, laughing with his companions.

The scent of the cigar smoke and the heavy weight of his patronizing hand triggered a violent physiological reaction in Cleo’s chest. Suddenly, the deafening club faded. She was twenty-five again, standing in a sterile, glass-walled boardroom. She remembered the laughter of the tech executives, the sickening realization that they had completely stolen her algorithms. They had patted her arm, called her ‘sweetheart’, and told her that a naive little girl like her didn’t truly understand the complex code she had written. They had looked right through her, stripping her of her intellectual property, her dignity, and her voice, leaving her with absolutely nothing.

The memory burned like acid in the back of her throat, but it forged a cold, diamond-hard shield over her mind. Let them call her Mouse. Let them think she was a vapid, clumsy idiot. Stupidity was the ultimate cloak of invisibility in a room full of arrogant predators. Their absolute certainty of her inferiority was exactly what was going to let her burn their empire to the ground.

She let out a hollow, vacant giggle, pulling the crumpled bill from her cleavage and waving it like a prize. "Thank you, sir! I’ll be right out of your way!"

Retreating toward the service corridors, the noise of the main floor muffled behind heavy acoustic doors. Her mind immediately splintered into a dozen rapid-fire calculations. Once she confirmed the chemical structure of the sample, she could contact the fence in the Narrows. He would demand a thirty percent cut, which left her exactly enough to bribe the clinic doctors to reverse Elara’s neurological damage. But the extraction was the volatile variable. If she cut the main power grid during the championship fight, the auxiliary generators had a three-minute lag. Three minutes in pitch blackness. It was enough time to drag Elara through the eastern ventilation shaft, provided the lab hadn’t upgraded the biometric locks on the grates.

Cleo slipped past the bustling kitchens and ducked into a small, unmonitored utility closet near the loading dock. She locked the heavy metal door behind her, plunging the space into dim, flickering fluorescent light.

Finally breathing out, she let the ‘Champagne Mouse’ persona drop. Her spine straightened. The vapid emptiness in her eyes vanished, replaced by a sharp, calculating intensity.

She slid the stolen vial from her sleeve. The liquid inside caught the bad lighting, shimmering with a thick, golden viscosity. The VIPs were paying ten thousand dollars a drop for this stuff, believing it was an elite, unadulterated combat stimulant.

Cleo reached into the lining of her skirt and pulled out a chemical testing strip—a highly sensitive reagent designed to detect synthetic amphetamines and raw narcotics. She uncorked the vial with her thumb. It didn’t smell like chemicals.

Using a sterile dropper, she placed a single golden bead onto the testing paper.

She waited for the strip to turn the deep, violent blue that would indicate a narcotic base. But the color didn’t change.

Instead, the moment the liquid made contact with the oxygenated surface of the paper, it began to react aggressively. It didn’t spread; it coagulated. Cleo leaned in closer, holding her breath. The golden drop was webbing, forming microscopic, fibrous tendrils that pulsed slightly before hardening. A heavy, metallic odor filled the cramped closet.

The scent of raw iron.

The cold realization hit her so hard her knees locked to keep from collapsing. The test strip dropped from her trembling fingers. This wasn’t a narcotic. It wasn’t a designer drug cooked in a beaker.

It was blood.

Synthetic, genetically modified human blood. And Vance was feeding it to the wealthiest men in the city, the girls on the floor, and the fighters in the cage. The Golden Cage wasn’t an exclusive nightclub dealing drugs. It was a live human trial, and they were all infected.
