Prologue

The sublevel of the research facility was a dark monument to buried ethics. It offered none of the pristine sterility expected of a modern laboratory. It lacked the gleaming stainless steel or the quiet buzz of HEPA filters. Instead, the subterranean corridor choked under a physical miasma. It was a layered stench of cloying rot with decay sitting weighty at the bottom, pierced by the eye watering ammonia sting of dozens of unwashed holding cages. Intermittent fluorescent tubes flickered overhead, casting a sickly glow over discoloured plastered walls. Dr. Asikov didn’t mind. He walked through the echoing hall with the casual gait of a man strolling through a garden. To him, the foul odour was nothing more than the ambient hum of existence. It was the smell of biological failure. To his calculating mind it was the scent of organic matter practically begging for his refinement. Flesh, in his eyes, was a flawed blueprint. Life was just an equation waiting to be balanced.

Inside the reinforced anguish of observation cell nine, a mongrel huddled in the furthest corner. He was a brittle architecture of bone and terror; his ribs visibly straining against a dull coat of patchy fur. The animal’s hind legs trembled against the freezing concrete, its wide glassy eyes tracking every shadow. He had been dragged from an alleyway three days ago, lured by the deceptive kindness of an outstretched hand and a piece of processed meat. That single scrap of warmth had fooled the dog into believing the cold nights were over, that he was finally safe from the kicking boots of the city. He didn’t know the difference between a rescuer and a captor. The facility certainly didn’t care. To the administration and the men in rubber aprons who had weighed and bled him. He wasn’t a dog; he was biomass. A variable to be tested, measured, and then incinerated. 

Sitting just outside the secure glass of the cell enclosure, resting on a tray, lay a small ceramic scoop. It was filled with a coarse, ash grey dust that seemed to absorb the sombre light around it. Apex. It looked harmless, like crematorium sweepings, but it was the refined culmination of four years of quiet state-sanctioned nightmares. It was the final product of black budget funding, midnight incinerator burns and biological anomalies that defied natural law. 

‘Subject fourteen,’ Asikov muttered into his dictaphone. His voice a flat rasp, entirely devoid of empathy.

He didn’t look at the dog. To look at the subject was to acknowledge it as a living creature and Asikov traded in metrics, not mercy. Instead, his cold eyes remained locked on the glowing telemetry monitors. Tracking the erratic, terrified spiking of the animal’s heart rate. His gloved finger hovered over the console’s illuminated keypad.

‘Commencing ingestion protocol.’

The harsh scrape of the latch disengaging echoed sharply down the corridor. Asikov stepped into the cramped enclosure. The dull thud of his rubber-soled boots against the damp floor sounded unnaturally loud in the tight space. Each step was a measured, inevitable countdown. Most test subjects fought or at least bared their teeth in a final, futile display of survival. This dog didn’t growl. It was already deeply broken. The mongrel scrambled backward, its overgrown claws scraping uselessly against the slick concrete. Pressing itself so hard into the corner it seemed to be trying to merge with the wall. Its tail was tucked tight against its hollow, trembling belly. When the animal looked up at Asikov, its eyes were white rimmed and shining with a desperate, ancient fear. The primal terror of a creature trapped with a predator it could not understand.

Asikov didn’t pause. There was no hesitation, no soothing whisper or momentary flicker of doubt. He descended upon the animal with ‌calculated, clinical brutality. His hand snapped out, seizing the loose scruff of the dog’s neck and pinning it immovably against the floor. The animal released a strangled whimper, but Asikov ignored it, ruthlessly prying the resisting, foam-flecked jaws apart with his free hand. He tipped the ceramic scoop, dumping the grey dust directly onto the back of the dog’s dry tongue. It coated the throat instantly, filling the small space with the sharp scent of ozone and pulverised metal.

Before the dog could cough, gag, or expel the grit, Asikov clamped both hands firmly around its muzzle, locking its jaws shut with vice-like pressure. Stretching the animal’s neck, he forced its head back to manipulate the airway. He knelt there in the dim light, feeling the frantic fluttering of the dog’s heart vibrating through its ribcage and against his own knee. He waited with cold patience. The dog thrashed, its eyes rolling back in its skull as it choked on the dry invasive powder. Finally, the base reflex of biology overrode the panic. A convulsive swallow visibly travelled down the animal’s throat. The dose was delivered. The nightmare had successfully found its host.

For ten agonising seconds after the forced swallow, nothing happened. The dog simply cowered on the concrete, panting heavily, strings of thick saliva dripping from its lips as it braced for another blow. Then the change began. It wasn’t immediate, but it was profoundly visceral. The dog didn’t yelp or struggle. Instead, it went entirely rigid. Every undernourished muscle in its body seized at once, pulling so taut that the tendons beneath its skin stood out like frayed steel cables. Its head snapped back with a sudden, bone cracking jolt. The neck overextended as if violently jerked upward by an invisible wire hooked directly into the base of its skull. The matted fur along its spine bristled, standing straight on end as a wave of feverish heat began to visibly radiate from its core, causing the cold air around it to shimmer.

Then came the sound. It wasn’t a bark, a whine, or anything recognisable as distress. It was a wet, rattling wheeze. An horrific stuttering exhalation that sounded exactly like pressurised air tearing through a punctured tire. It was the sound of lungs suddenly forgetting their purpose. A diaphragm paralysed by a foreign, hostile command. Asikov stepped backward safely behind the reinforced glass and leaned in. The jarring reflection of the overheads danced across his spectacles as his eyes widened in morbid, fascinated triumph. He wasn’t watching a dog perish; he was watching a biological equation finally balance.

He watched intently as the mongrel’s eyes underwent a gruesome metamorphosis. The frightened, milky brown irises shuddered before the pupils dilated, expanding outward like black ink bleeding rapidly through wet parchment. In a matter of seconds, the colour was completely swallowed, turning the dog’s panicked gaze into two bottomless black voids. The desperate fear that had been there only moments ago vanished. There was no terror left in them anymore, no pain, no consciousness. The original occupant of the biological machine had been abruptly evicted.

Asikov picked up his dictaphone, his voice steady, clinical, and completely unbothered by the grotesque display unfolding inches away.

‘Autonomic response is fading,’ he dictated, his thumb pressing firmly on the recording switch as he watched the monitor’s flatline, then immediately begin to spike in an erratic, impossible rhythm. ‘Subject has ceased natural respiration. Neurological overwrite initiating.’

On the cold concrete, the mongrel stopped trembling. The transition was marked by a chilling stillness. A fraction of a second where the room seemed to hold its breath. Then it rose.

The movement was a stiff, stumbling mockery of animation. The creature didn’t push itself up naturally; its limbs jerked and locked as if struck by an invisible electrical current. Each step was a disjointed heave of dead muscle fighting against rapid chemical rigour. Its joints crackled loudly in the tight space, sounding like snapping dry branches. Tendons seized and slipped in uncoordinated bursts, driving its stiff limbs upward in a series of uncoordinated lurches. Its spine arched at an abnormal angle, the vertebrae audibly grinding against one another as the newly formed neural pathways forcefully commandeered the host. There was no fear left in those bottomless black eyes. There was no dog left either. The frightened stray from the alleyway was completely gone, completely overwritten. In its place stood a vessel for a primal predatory hunger that had never known a collar, never felt warmth, and recognised no master.

Asikov took a half step back, his hand instinctively gripping the release latch of the door. It was a rare, involuntary twitch of self-preservation. Inside the enclosure, the creature let out a low, strangled growl that vibrated through the thick glass. It wasn’t a sound of warning; it was a sound of anticipation. Its jaw snapped and unhinged slightly with a sickening crack, the facial ligaments tearing to accommodate an impossibly wide bite, exposing gums that were rapidly turning a necrotic bruised purple. Thick, coagulated saliva dripped onto the floor, hissing faintly against the concrete.

‘Apex is not a failure,’ Asikov whispered to the empty room, his smile thin and chillingly vacant in the blue light of the monitors.

As the creature coiled its muscles and lunged, hurling its broken body toward the glass with explosive speed, Asikov did not retreat further. The scientist vanished, replaced instantly by the executioner. With calm, practiced precision born of countless identical trials, he reached for the service pistol holstered at his hip. He drew the weapon, levelled it smoothly through the enclosure’s hatch, and squeezed the trigger. He fired a single, deafening shot.

The hollow-point round caught the creature mid leap, shattering its skull and severing the newly formed brain stem. The dog collapsed instantly, dropping like a sack of cement and smearing against the glass as it slid into a lifeless heap. Its predatory hunger was permanently silenced before it could even land its strike. The vociferous ring of the gunshot slowly faded down the corridor, leaving only the metrical beep of the flatlining monitors and the sharp, acrid sting of burnt cordite mingling with the stench of decay.

Asikov stepped through the doorway of the enclosure, his boots crunching softly over fragments of shattered bone. He stood over the steaming carcass, watching as the unnatural, feverish heat generated by the mutation met the damp chill of the sublevel, curling upward from the matted fur in wispy tendrils of vapour. He didn’t flinch at the gruesome, twisted angles of the dead creature, nor did he mourn the violent destruction of the host. Instead, he calmly produced a stark white handkerchief from his pocket, methodically wiping a single fleck of dark, thick blood from the polished lens of his spectacles.

Sliding the glasses back onto his face, he reached for the tactical radio clipped to his belt. His thumb found the transmission button, depressing it with a sharp, static-laced click that severed the lingering silence of the room.

‘Control, this is Asikov,’ he stated, his voice as flat and sterile as the data scrolling across his monitors. He looked down at the lifeless, mutated mass at his feet, seeing only the undeniable validation of his life’s work. 

‘Subject fourteen is terminated. Ingestion protocol achieved a total neurological overwrite in under forty seconds. Aggression output is absolute.’ 

He released the button, letting the radio hiss for a moment before pressing it again, an alarming serene stillness settling over his features.

‘The Apex compound is viable. Empty the remaining cages and begin preparations for phase two.’

Chapter One

HMP Blackwood didn’t so much wake up as drag itself from a miserable stupor, lethargic and resentful every single morning. It always started with the pipes. They groaned and ached behind the sodden block walls. An empty, rattling wheeze like the lungs of something decrepit that simply refused to die. Then came the strip light. A cheap drone that stuttered reluctantly to life, washing Liam Thorne’s cell in a jaundiced, apathetic yellow. Liam was already staring at the ceiling. He was always awake before the light, numb to the clammy chill. Just waiting for the day’s misery to begin. 

He lay flat, anchored to the paper thin mattress. The dead air in the eight by six box sat stagnant in his lungs, leaving a foul, metallic tang on his tongue. A grim cocktail of cheap disinfectant and the sour lingering sweat of a thousand forgotten men who had rotted in this exact bunk before him. He shoved the scratchy woollen blanket aside with a dull sense of resentment, shivering as the depressing, weeping air of the British autumn gnawed right through the cheap grey cotton of his prison issue sweatshirt.

He stood, taking the customary one and a half steps it took to cross his entire world, and stopped in front of the scratched metal mirror above the stainless steel toilet. The face looking back at him was greyer, leaner and harder than the mechanic from Portsmouth he used to be. His eyes remained the same. Desperate. Focused. He reached under the thin seam of his mattress and pulled out a blunt stub of a pencil along with a small, dog-eared pocket calendar. It was a cheap paper booklet provided by the prison chaplaincy during his first week inside. Its edges were now curled and soft from two years of constant handling. He smoothed it open on the cold rim of the sink. Deep, uncompromising crosses marked hundreds of the tiny printed squares across the preceding pages, documenting the sheer volume of dead time in faded graphite. He flipped to the last page. Just twenty one empty squares remained. They formed a short, agonising path leading to a specific date. A date circled so many times that the pencil had nearly torn right through the cheap paper. The day he got to go home. Twenty one days. Three weeks until he could walk out of the colossal wrought iron gates. Three weeks until he could hold Maya again. The thought of his daughter’s small arms around his neck was the only thing keeping the crushing claustrophobia of C-Wing from snapping his mind in two. He added a firm, dark cross through the day’s date.

He dropped his gaze to his hands, resting them flat against the water stained rim of the sink. The deep set grime and motor oil that had once permanently stained his hands were long gone. Bleached away by two years of caustic, industrial prison soap. He missed the sharp smell of petrol. He craved the honest exhaustion of a twelve hour shift spent wrestling with seized engines under the bonnet of a cramped motor. That was the quiet, unremarkable life he was supposed to have. Before the drunk driver. Before Chloe was killed.

The familiar ache flared in his chest, heavy and oppressive. Grief had made him sloppy. Desperation had made him stupid. When the bills piled up and the garage threatened to go under, he’d taken a lifeline from a local firm of loan sharks just to keep a roof over Maya’s head. Before long, the interest was a noose, and when he couldn’t pay; they came to collect. Not in cash, but in favours. Liam closed his eyes, leaning his forehead against the cold mirror. The arid air of the cell vanished, replaced by the phantom, coppery stench of blood on a warehouse floor. It was supposed to be a simple task to clear his debt. An empty lock-up, a quick bit of lock picking and he was out. Unfortunately, whoever cased the joint for the syndicate had botched it completely. A night watchman was on duty. The industrial lock-up was supposed to be empty until morning. Liam was only there to bypass the security gates so the crew could strip the high-end motor parts inside. A quick job to finally be free. The moment Liam popped the lock and they breached the side door, a blinding beam from a heavy duty torch cut through the dark of the warehouse. Behind the glare was a night watchman who looked to be pushing seventy. Just a frail old guy in an oversized high-vis jacket, trying to earn a living on the graveyard shift. A thermos of tea slipped from his trembling hands, shattering on the concrete floor.

‘Now look here lads, there’s no need for…’ the old man started.

His voice was thin and reedy, cracking with a sudden frozen shock as he stumbled backward. He raised his free hand in a desperate, instinctual gesture of surrender. Liam saw what was coming in sickening slow motion. He saw the dead flatline in Ronny Lawson’s eyes, a heavyset animal who collected the firm’s weekly interest. He saw the ruthless enforcer shift his weight, planting feet wide on the dusty floor. There was no hesitation, no warning shout. Not even a sharp command for the old man to stay quiet and look at the wall. Lawson just tightened his leather gloved grip on the steel crowbar he was wielding, drawing it back past his shoulder.

‘Ron, wait!’ Liam shouted, stepping forward, his hand reaching out to grab the brute’s arm. He didn’t even get to finish the sentence.

Ronny pushed forward, closing the distance in two massive strides. The old man tried to raise his arms to protect his head, but Ronny simply adjusted his grip and swung his crowbar like a baseball bat. He bypassed the watchman’s hands entirely, driving the weapon flush into the old man’s side. His knees cracked against the concrete before he rolled onto his shoulder. He curled into a tight, shivering ball among the spilled tea and the shattered glass of his thermos. His frail hands grabbed desperately at his side, his knuckles white as his fingers dug into the cheap nylon of his jacket, looking as though he were trying to physically hold his splintered ribcage together. The stifling silence of the warehouse rushed back in, broken only by the frantic gasps of the old man desperately trying to pull oxygen into a punctured lung.

When Ronny raised the crowbar to strike again, aiming directly for the old man’s skull, something inside Liam snapped. Liam was a lot of things. He was a decent mechanic, a broken husband, and a desperate thief who had let a syndicate back him into a corner just enough to keep the heat on for his little girl. As he stared at the old man gasping on the cold floor, he knew exactly what he wasn’t. He wasn’t a killer. His weighted canvas tool bag slipped from his grip, hitting the floor with a dull thud, and Liam turned on the men who had brought him there.

He didn’t think; he just moved. The instinct bypassed his brain entirely, driven by a sudden surge of pure adrenaline fuelled revulsion. He dropped his shoulder and launched his entire body weight forward, driving it flush into Ronny’s chest just as the beast braced to swing the crowbar again. The impact sounded like two heavy sides of beef colliding, driving the air from Ronny’s lungs in a surprised grunt. Liam tackled him backward, their tangled bodies crashing hard into a stack of wooden shipping pallets. The dry, brittle wood collapsed on top of them in a shower of splinters and rusted nails. The warehouse instantly erupted into utter chaos. The echoing crash shattered the frozen silence in the dark and the beam of the dropped torch rolled erratically across the concrete floor, casting wild, distraught shadows against the corrugated steel walls. There were three of them in the firm’s crew. Hardened, vicious grunts who made their living breaking bones on seedy streets, and the sheer, momentary shock of being hit by their own safecracker evaporated in a heartbeat. They completely forgot about the old bleeding watchman on the floor. Instead, their eyes locked onto Liam as he scrambled to his feet, the shock instantly curdling into a murderous rage as they turned their collective savagery entirely on the mechanic who had just crossed them. 

Liam took a brutal, systematic hiding for his trouble. A wrench caught him flush on the cheekbone, fracturing it instantly and filling his mouth with the hot taste of his own blood. A cruel stomp came down directly on the side of his knee, tearing cartilage and snapping the joint with a sickening pop that sent a crippling surge of agony up his thigh. With only thoughts of his daughter, Liam refused to stay down. Fuelled by a raw, desperate rage, Liam fought back with the hands of a man used to wrestling engine blocks. He shattered Ronny’s nose with a furious right hook and threw another thug backward over a metal workbench, turning the lock-up into a bloody, frantic brawl. Liam absorbed the punishment, throwing himself over the old man, shielding the watchman’s fragile frame with his own battered body. He fought them off just long enough. He was kneeling on the cold floor, pressing his grease stained jacket against the watchman’s bleeding chest to stem the flow, when the piercing blue wail of police sirens finally cut through the night air.

The syndicate boys scattered into the dark like rats, leaving Liam behind. He didn’t run; he just sat there in the dust and the blood, his face swelling shut, waiting for the flashing lights to flood the warehouse. He knew his life as a free man was over, but as the old man took a ragged, surviving breath, Liam knew he had kept his soul.

The detectives had pressed him relentlessly in the sterile, windowless interview room. Dangling reduced sentences and immunity deals right in front of his heavily bruised, swollen face. They knew exactly who the firm was, and they desperately wanted the names of the men who had put the elderly watchman in intensive care.

Liam hadn’t grassed. He knew exactly how the brutal, unspoken rules of that life worked. When the day finally came, he had stood completely rigid in the polished wood of the courtroom dock. He ignored the prosecutor’s damning summary, kept his mouth firmly shut and stared blankly at the crest above the judge’s head, taking the two year stretch on the chin without a single flinch or plea for leniency. He didn’t even acknowledge the two men sitting quietly in the back row of the public gallery. Syndicate spotters, sent there to make absolutely sure the mechanic kept his word. If he had opened his mouth and pointed the finger to save his own skin, the firm wouldn’t have bothered trying to get to him on the inside. They were cowards at heart, and they always went straight for the soft underbelly. Naming the crew would have instantly painted a massive, bloody target squarely on the front door of his sister Jo’s house. A brick through the window in the dead of night, a petrol bomb pushed quietly through the letterbox. 

It was a price Liam simply couldn’t pay because inside that house, tucked safely beneath a duvet with her favourite stuffed animals, his little girl Maya slept. She was entirely oblivious to the violent, terrifying nightmare her dad had fallen into. To her, he was just working away for a little while. Taking the sentence, the degradation and the oppressive isolation of a concrete box was the only way Liam could guarantee the firm’s monsters stayed permanently out of her world.
