Part I
The public face of MI5 was files and offices, surveillance vans and unmarked corridors. But in the cracks of London, in the ruins and underpasses, in hollowed-out places where even the Thames refused to flow clean, another war raged.
Jackson Lamb was its dirtiest weapon.
To most, he was the wreck of a man, overweight, whiskey-stinking, a walking insult in a crumpled suit. But those who’d served alongside him knew better. In Berlin, in Belfast, in alleys where ordinary men bled out, Lamb had worked with tools not listed in the official archives. Iron sigils scratched into walls, curses muttered over fire, the kind of warcraft whispered about but never acknowledged.
Jackson Lamb was not just MI5’s spymaster of misfits. He was something older: a warlock in the Service of the Crown, a man who’d learned to weaponize ruin itself. His powers weren’t showy, but they were lethal. Blood sense, he could smell a wound, a weakness, the iron in a body’s fear. Binding tongue, his words carried weight; when he commanded, the air itself bent to listen. Shadow wards, invisible but real, they cloaked rooms, confounded enemies, and made men doubt their eyes. And finally, Wolf’s guile, not true shapeshifting, but something close: predatory cunning, patience, and hunger honed until it felt inhuman.
Yet power corrodes. Lamb’s health, his stench, his ruin, all of it was the price of years spent steeped in this work.
Catherine Standish knew that price too well.
By day, she was the quiet keeper of Slough House’s ghosts, files, and failures. But before she drowned herself in the bottle and shame bent her shoulders, she had been something else entirely: a witch born.
Her gifts were subtle, precise, and never gaudy. Wards and bindings were her specialty; she could draw a circle that no monster could cross. Divination by reflection, glass, water mirrors: truths surfaced there, though they often looked back at her. Healing by burden, she could draw poison or sickness from another, but it lived in her body until it burned away. The ancestral voice, the echoes of the witches that came before her, whispering in her head, providing guidance, accusations, and hunger. And finally, the Forbidden Affinity, blood-magic. She had tasted it once, long ago, in a moment of weakness and temptation. Lamb had been there when she did. She had sworn never to touch it again. But the world had other plans.
It had been twenty years, give or take. Catherine remembered the night by scent first, the reek of rust, grease, and wet dog, thick enough to coat her tongue. She’d followed Lamb through rain-slick alleys of East London, back when the docks still clattered with cranes and half-abandoned warehouses rotted at the river’s edge.
He hadn’t told her much. He never did. Just a muttered, “Bring your chalk. We’ve got a pest problem.”
When the steel door of the warehouse screeched open, the sound that greeted them was inhuman. A low, guttural growl, rising into a howl that made her skin crawl.
The werewolf was caged, but barely. Heavy chains looped through girders, links as thick as her wrist. The creature was half-shape, caught between man and beast, its limbs warped, its jaws sprouting too many teeth. Blood stained its fur, fresh and old alike. It stank of slaughter.
Catherine had frozen. Her hands clutched the pouch at her side, the chalk rattling inside.
She’d wanted to turn back.
“What is it you think I’m supposed to do here, Jackson?” she’d whispered.
Lamb had lit a cigarette, the flare of the match lighting his ruined face in orange. He looked her over, unimpressed, and spat smoke into the dark.
“You bind, don’t you? That’s your trick. So, bind it.”
Her mouth had gone dry. “If I make one mistake…”
“It’ll rip your throat out and use your bones as toothpicks. Yes, I’m aware.” He’d coughed, then smirked, eyes glinting. “So don’t make a mistake.”
The beast had thrown itself against the chains, steel groaning, the floor vibrating with its fury. Catherine had stumbled back, panic rising like bile. Her hands shook too badly to hold the chalk steady.
“I can’t,” she’d whispered. “I can’t do this.”
That was when Lamb’s tone had shifted. Not soft, never soft, but sharp, cutting straight through her fear.
“Look at you. Terrified. Shaking. But you’re still standing here. You didn’t run when you saw it. You haven’t bolted. You know what that is?”
Her breath hitched. “Stupidity?”
His grin had been filthy, but his eyes were steady on hers. “Strength. That’s strength, Standish. Fear’s just proof you’re not dead yet. What matters is what you do with it. We’re all damaged goods here. Use the damage.”
The beast howled again, straining. Its breath steamed the air, stinking of copper and meat.
“Do it,” Lamb had ordered. “Now.”
And she had.
On the cracked concrete, chalk lines formed a circle, her hand jerking with tremors at first but finding its rhythm. Sigils inked into muscle memory long neglected. Her voice joined, low, shaking but steadying, the syllables tasting of iron on her tongue. The forbidden affinity.
The air thickened. The circle glowed faintly.
When the werewolf lunged this time, the chains broke, but the circle held. It smashed against an unseen barrier, snarling, eyes wild, claws screeching as if against glass. It battered again and again, but it couldn’t cross.
And it was her. Her circle. Her power.
The realization hit her like fire in her veins: she was holding it. Not the chains, not Lamb, her. The creature’s strength, its fury, its hunger, all of it stopped dead by the lines she had drawn on a forgotten warehouse floor.
Lamb had laughed then, a savage private delight, then clapped once, slow and mocking, smoke curling around him like a protective layer of filth.
“See? That’s it. That’s power, Standish. You did that. Not me, not the chains. You.” He leaned closer, eyes gleaming through the haze. “Remember that feeling. Monsters kneel when you tell them to.”
Her chest had swelled, not with pride exactly, but with a dangerous thrill that tasted better than alcohol ever had.
For the first time in her life, she’d felt indispensable. And Lamb had been the one who showed her.
Now, about 20 years later, the letter had come, scrawled in his disgusting handwriting, reeking of stale smoke even through the envelope. Come. You’ll want to see this. No signature. None was needed.
Part II
Slough House, Halloween night
Rain had been falling all day, a fine, bitter drizzle that turned London’s streets into dark mirrors. By dusk, the air was slick with cold, and the city smelled of stone and rust, of wet paper decaying in the gutters. The kind of weather that seeped through your coat, through your bones, and settled somewhere behind the heart.
Catherine Standish paused on the threshold of Slough House, clutching her umbrella. The building loomed against the night like a condemned relic, its windows smeared with grime, its bricks blackened by decades of soot. The faintest flicker of candlelight glowed behind one pane on the top floor, no one’s desk lamp, no bureaucrat’s late-night toil, but something older, a vigil flame.
She almost turned back. She had sworn never to come here after dark, not again. Not when the shadows lengthened, not when he was most himself.
Inside, the stairwell was steep and narrow, smelling of wet plaster and rodent droppings. Each step creaked under her shoes, and the sound seemed to echo back unnaturally, as though the walls themselves were listening. By the time she reached the landing, she could hear him. That rasping cough, the sound of phlegm tearing loose from a ruined throat.
“Standish,” came the voice. Gravel and grease, thick with mockery. “You look like death warmed up. Fitting.”
He was waiting in his office, hunched in that battered chair, his coat hanging off him like a molted skin. The room was hazy with cigarette smoke and something else, heavier... a stink of ash and herbs, charred offerings burned in bowls she could just make out on the shelves. The candlelight painted the sagging walls a jaundiced yellow.
Lamb looked as foul as ever: greasy hair plastered to his skull, shirt stained beyond recognition, eyes like two slits cut into a waxy, sagging face. But beneath the filth, Catherine felt it immediately, the thrum. Power, dark and rotten, coiling in the air around him like invisible smoke. It prickled the hairs on her arms, made her skin ache.
“You’ve been stirring the pot again,” she said, forcing steadiness into her voice.
He grinned, lips curling back to show teeth stained brown. “Funny you should mention that, Standish. When something nasty crawls out of the dark, I always ask myself, who’s fool enough to still give a damn? And then I remember.” He gestured toward her with his cigarette, ash drifting down like grey snow. “You.”
Catherine swallowed hard. The smoke in the room tasted wrong, metallic, like iron in water. On the desk lay a file, but the edges of the pages were warped, as if they’d been soaked in blood.
“Tell me,” Lamb went on, leaning back with a groan. “When was the last time you dreamed of them?”
Her throat tightened. She hadn’t spoken the word in years. Hadn’t dared. Yet in her chest, the old fear stirred, sharp and cold as the October wind outside. Vampires.
And for the first time since opening that cursed envelope, she wished she had never come.
Catherine stood in the doorway longer than she meant to. The smoke swirled around her like a curtain, stinging her eyes, sour on her tongue. She should leave. She knew this. Every part of her body whispered it.
But Lamb smiled, or something like it, and she froze.
“You’ve lost weight,” he rasped, flicking ash into an empty mug. “Not that you had much to spare. You eating, Standish? Or are you back to just drinking your meals these days?”
Her jaw tightened. He always knew where to cut. Always pressed the blade in without effort.
“Don’t,” she said. Quiet, but sharp.
“Touchy.” His eyes gleamed like wet coal. “Relax. It was a compliment.” He gestured toward the empty chair across from his desk, the ancient thing scarred with knife marks and burns. “Sit. Pretend this is a date. Candlelight, intimate setting. All we’re missing is a nice bottle of wine, though I suppose you’d prefer holy water.”
“Don’t make jokes about that.”
“Why not? It suits you.” His grin widened, a stretch of teeth in smoke. “A sweet little white witch who broke her vows, crawling back to the devil she knows.”
Her stomach knotted. He was playing with her, the way he always had, like a cat with something trembling in its paw. Yet there was more behind it tonight. A tension in the air. Something hungry in the way his gaze held her, raking across her face as though he could see the pulse hammering in her throat.
“You wrote me,” she said, refusing to sit. “You said I’d want to see this. Show me and be done.”
Lamb chuckled, a wet sound that became a cough. He hacked into a handkerchief, then balled it up and tossed it on the desk. It landed perilously close to the warped file. “Always in a rush. That’s the trouble with you, Standish. No patience for foreplay.”
Her cheeks burned with anger, with shame, with something else she refused to name. The room seemed smaller now, the walls pressing in, the smell of smoke and sweat and something coppery winding tighter around her.
“Do you remember the last time?” he asked softly.
The words hit her like a stone.
She remembered. Of course, she remembered. The night twenty years ago, when the ritual circle blazed red and the thing with eyes like lanterns had stepped out of the dark. She’d been younger then, terrified, trying to drag him back before the abyss swallowed him whole. He’d laughed in the creature’s face. And afterward, afterward, when the air still stank of sulfur and blood, he’d leaned close, too close, and whispered what it would be like if she stopped resisting, if she took his hand and followed him all the way down.
Catherine’s breath caught. She hated herself for it, but even now, a flicker of that whisper stirred in her veins.
“Don’t,” she said again, but her voice was thinner now.
Lamb tilted his head, studying her like a puzzle. “You’re still afraid of me,” he murmured. “And you still like it.”
Her hand trembled around the strap of her handbag. She wanted to run. She wanted to slap the smirk from his ruined face. She wanted...
A sound at the window.
A faint tap, like fingernails on glass.
Both their heads turned. The candle flame flickered as though some unseen breath had passed over it.
Lamb’s grin sharpened. “Right on cue,” he muttered. Then, almost lazily, he looked back at her. “Still want to leave?”
The tap came again. Not the casual rattle of a loose pane, not the scuttle of rainwater. Deliberate. Fingernails, slow, dragging down the glass.
Catherine’s chest tightened. She forced herself not to move, not to give it the satisfaction of her flinch. The candlelight stuttered again, shadows stretching and folding across the walls.
“Don’t,” she whispered, though whether to Lamb or the thing outside she couldn’t tell.
“Don’t what?” Lamb’s voice was amused, lazy, though his eyes gleamed with a sharpness she hadn’t seen in years. He was alert, coiled, his filth-ridden exterior barely concealing something ancient and eager beneath. “Invite it in?”
Her skin prickled. He knew. Of course, he knew.
The sound came a third time, but louder now, knuckles rapping against the pane with the insolence of a guest who would not be ignored. Catherine dared a glance. The glass was slick with rain, reflecting only the candlelight. But behind the smear of water, she glimpsed it. A pale face pressed to the window.
Not human.
The features were all wrong: the eyes too large, glistening black like a crow’s; the mouth a soft gash that stretched when it smiled, revealing too many teeth. Its breath fogged the glass from outside, though the night was cold enough to frost bone.
Catherine staggered back, her handbag slipping from her grasp. “God,” she breathed.
“Not quite,” Lamb drawled, flicking ash from his cigarette. “Though it does a decent impression.”
The face leaned closer, the teeth scraping the window as though testing its strength. A long, forked tongue left a wet trail on the glass.
“Why... why is it here?” Catherine whispered, her throat tight.
“Because I asked nicely,” Lamb said, smoke spilling from his lips. Then he chuckled. “You didn’t think I invited you over just to reminisce, did you?”
Her stomach dropped. “You...you brought this?”
“I summoned it,” he corrected, levering himself up in his chair with a grunt. The leather creaked beneath him. “They’ve been slinking around the city for weeks. Feeding in alleys, sewers, and on the riverbanks. The trick is, Standish, they’re pack animals. You see one, you can be sure the rest aren’t far behind.”
The glass rattled as the thing outside pressed harder, its nails screeching along the sill. The window frame groaned. Catherine felt the weight of its gaze fixed on her, heavy and unblinking.
She stumbled back, only to find herself caught by Lamb’s presence behind her. The smoke, the heat of him, the smell of rot and whiskey clinging to his coat. She realized with a shudder that he had risen from his chair and now stood close enough that she could feel his breath stir the hair at her temple.
“Trapped,” he murmured, low and obscene, savoring the word. “By them on one side, me on the other. Question is, Standish…”
His lips nearly brushed her ear as he whispered:
“…which one frightens you more?”
The window groaned again, a crack shivering across the glass. The candle flame flared, sputtered, and nearly died.
Catherine, trembling, realized there was no escape. Not tonight.
The glass screamed. A crack jagged across the window like lightning frozen in place. Rain leaked through, dribbling black down the sill. The thing outside pressed harder, its eyes like pits in the night, its teeth scraping, eager.
Standish felt her throat seize. Her hands, slick with sweat, twitched toward her bag where chalk and string, tools she swore she would never touch again, lay hidden in their old pouch. She had brought them out of habit, out of dread. A gambler carrying chips to a casino, she vowed not to enter.
Behind her, Lamb’s bulk loomed, his stink of cigarettes, whisky, and damp wool filling her nose. She could feel his amusement like a hand on her back, pushing her toward the abyss.
“Well, Standish?” he drawled. “I could let it in, see how long it takes to chew through us. Wouldn’t last long, me. Too gristly. You, though…” His lips smacked. “Fresh. Sweet. Like marrow pulled from the bone.”
Her heart pounded. “You bastard.”
He leaned closer, almost nuzzling her hair, though she knew it was mockery, more than tenderness. “True. But at least I’m your bastard.”
The crack widened, a spiderweb crawling toward the frame. A claw, black, slick, jointed too many times, slid through, curling inward like a finger beckoning.
She backed away, stumbling, until Lamb’s hand shot out, startlingly firm, gripping her elbow. His skin was warm, too warm, like a fever, and the grip was not easily shaken off.
“You’ve still got the knack, don’t you?” he murmured. “A circle, a word, a little spill of blood. Go on. Show me.”
“No.” Her voice broke.
“Yes.” His eyes, narrow and wetly gleaming, pinned her. “Or do you want to see what happens when it gets inside? You’ve always been so squeamish, Standish, but even you can’t drink away the sight of what they leave behind.”
The thing at the window hissed, its tongue lashing against the glass. The pane bulged, ready to give.
She snatched the bag from the floor, trembling fingers tearing it open. Chalk spilled across her palm, white dust clinging like frost. For a moment, she couldn’t breathe... the memories choking her. The circle drawn years ago, the smell of burning flesh, the laughter that wasn’t human.
Her hand shook. “I can’t...”
“You can,” Lamb said softly. Almost coaxing. Almost kind, though the mockery never left his voice. “You’ve always been stronger than you think. That’s why I liked you. Still do.”
The words burned. Forbidden, dangerous, sharper than any blade. But the window shrieked again, the glass splitting. She dropped to her knees, scrawling the circle on the filthy floorboards, chalk snapping under her grip. Her breath came fast, shallow, tears stinging her eyes.
The circle closed. Power hummed faintly in the air, low and hungry, like a sleeping animal stirring. Standish whispered the words she hadn’t spoken in years, each syllable increasing her power.
The creature slammed the glass... and stopped. Frozen mid-motion, its black eyes narrowing. The crack in the window held. The tongue retreated. Its claws were splayed against the glass, frozen mid-scratch, its mouth stretched in a permanent snarl. The black eyes rolled, as if trying to escape a snare it could neither see nor understand. A hiss shivered in its throat, low and venomous, but it could go no further. The circle had tethered it like a leash around its throat.
The air in the office pulsed with her circle’s energy. Standish’s body shook with it, her heart hammering as though trying to tear free. The circle glowed faintly on the warped boards, chalk dust trembling as though stirred by unseen breath. It was nothing grand... a crooked ring, lines uneven, smudged where her hand had faltered. But power bled from it all the same, humming low in her bones.
Then Lamb crouched beside her, his knees popping, his breath hot on her cheek. He looked down at the circle, then at her. A grin split his ruined face.
“There she is,” he whispered. “My clever girl.”
The candle flame swelled, shadows crawling up the walls like dark vines.
Standish dropped the chalk, her chest heaving. Her fingers ached, her knees screamed from kneeling, but the greater pain was inside: that sour, hollow collapse of knowing she’d done it again. She had sworn never to. She had promised herself she’d left that behind... the words, the sigils, the rush that came with it.
But it was there, hot and filthy, flooding her veins: the exhilaration of power. The memory of what it had felt like the first time, years ago, when she and Lamb had walked the edge of damnation together. The circle closing, the pulse answering hers, the yes in her blood that she hated even more than the no.
Lamb crouched beside her, wheezing faintly with the effort. His knees cracked as though the bones themselves objected, but his grin was wide, too wide. His face, in the sick light of the candle, was both grotesque and… triumphant.
“Well, Standish,” he said, smoke curling from his lips. “Looks like the old girl’s still got it.”
She flinched. The words went through her like claws.
He tapped the chalk circle with a dirty fingernail. “Not bad for someone who’s been in retirement. A bit shaky on the lines, though. You should practice more.”
Her throat tightened. “I told you I wouldn’t.”
“You just did.” He leaned closer, his voice low, taunting, but beneath it was an unmistakable hunger. “And you liked it. Don’t bother denying it. I could smell it on you.”
The creature hissed again, thrashing against the invisible tether. The glass shuddered in its frame, but it could neither move forward nor retreat. The circle had caught it halfway, like a fish snagged on a hook. Its limbs twitched, jerking in unnatural spasms.
Standish felt the strain deep in her gut, a pressure that gnawed at her insides. Binding always took its toll; she had locked her will to its essence, and now the two strained against one another like dogs at opposite ends of a chain. Already her breath came short, her pulse racing. She knew she could hold it, but not forever.
Lamb saw the tremor in her hands. He saw everything.
“That’s it, isn’t it?” he said softly, almost admiring. “That’s the part you hate. Not the thing outside, not the chalk and muttering. The feeling. That thrill, when the leash snaps tight. It’s better than drink, better than smoke, better than sex.” His grin widened. “Not that you’d remember about the last.”
“Shut up.” The words tore out of her, raw.
“Why? Because I’m right?” His eyes narrowed, gleaming like oil. “That’s the trouble with you, Standish. You’re an addict. Doesn’t matter if it’s vodka or spells or me. You’ll swear it off, swear it’s killing you, and then you’ll crawl back on your knees the moment you need it.”
Her stomach turned, at him, at herself, at how true it was. The circle glowed faintly between them, the trapped vampire rasping at the window, its breath fogging the cracked glass. Its presence was suffocating, pressing at her chest even as the binding held.
Lamb leaned closer still, his mouth near her ear, the stench of smoke and decay thick around him. “The thing is, Standish…” His voice dropped to a whisper, intimate and obscene. “I like you best like this. When you can’t walk away.”
The circle pulsed once, hard, and Catherine gasped because for a heartbeat she felt not only the creature’s rage but Lamb’s satisfaction threaded through it. All three of them caught in the same net, thrumming with the same dark current.
And it terrified her more than the monster outside ever could.
Lamb eased himself back into his chair with a grunt, smoke curling around his head like a crown of filth. He watched her, eyes gleaming through the haze, as pleased as a spider who’d watched the fly step willingly into its web.
“Well, Standish,” he rasped. “That answers the question. Bit rusty, sure, but you can still sing the tune.”
Her mouth was dry. “Why did you bring me here?”
He tapped ash into the saucer beside him. “Because I need you.”
She laughed, sharp and bitter. “You don’t need anyone.”
His grin widened, brown teeth catching the candlelight. “Don’t flatter me. Truth is, Standish, I’m a hammer. Always have been. Smash, burn, break... that’s my trick. Works on plenty of things. But these buggers...” He jabbed a finger toward the window, where the vampire hissed like steam. “These don’t break the usual way. You can cut ‘em down, set ‘em on fire, hell, I’ve tried. They keep crawling back. Nasty habit of theirs. And I’m too bloody old to spend my nights playing whack-a-mole with vermin.”
Catherine stared at him. “So you summon one into your office? What were you thinking?”
He chuckled, the sound phlegmy, obscene. “Thinking it was time to bring you back. See, I can’t do what you can. Never could. You’ve got the hands for it. The blood. The knack. You bind ‘em, Standish. You seal ‘em. You make sure when they go down, they bloody stay down.”
Her stomach twisted. The Blood Seal. The one spell she’d sworn never to touch again. The one that had nearly cost her her soul.
“No,” she said at once, the word sharp, desperate. “You know what happened last time. I nearly...”
“Died? Lost yourself?” His voice cut her off, cruel and mocking. “Welcome to the bloody club. Look around.” He gestured at himself, his body sagging in his chair like a sack of rot. “You think I came out of all this looking like a cover model? You don’t get the prize without the scars, Standish.”
She knew what Lamb was asking: not just to trap it, but to seal it, to tie it to her veins so that it could be destroyed.
“Why me?” Her voice cracked. “Why not some other witch, some coven, anyone else?”
His grin vanished. His gaze sharpened, cruel and intimate all at once. “Because they’re not you. You’ve got the precision. The discipline. Most of ‘em want fireworks, rituals, grand bloody gestures. But you…” He leaned forward, smoke curling from his lips. “You’re quiet. Careful. Exact. You make it stick.”
She swallowed hard. “And you think I’ll just do this for you? After everything?”
“Not for me.” He shrugged, settling back, his coat creaking. “For them.”
“Them?”
He jabbed a thumb toward the window again. “More where this came from. Nest of the bastards down by the river. Feeding every night. It won’t take long before they stop being choosy. Half this city doesn’t even know what’s crawling under its skin. You think you’re the only one who’s seen through the veil? You’re not. But you’re the only one who can bloody fix it.”
The silence stretched, broken only by the vampire’s hiss and the steady drip of rain down the cracked glass. Catherine’s chest felt tight, her shame pressing in heavier than the air.
“And why did I come?” she whispered, more to herself than to him.
Lamb smiled again, this one softer, crueller. “Because you wanted to. You always do. No matter how many times you swear me off, no matter how many little circles of self-pity you sit in, you’ll answer when I call. Because you like it, Standish. The fear. The power. Me.”
Her breath stuttered. “You’re disgusting.”
“And you’re still here.” He raised his cigarette in a mock toast. “Which tells me everything I need to know.”
The vampire’s hiss rattled the glass, black tongue striking the pane. The binding circle pulsed faintly on the warped boards, answering its fury with a responsive tug in her blood. Catherine’s breath came short, sharp, every beat of her heart echoing the creature’s struggle.
She pressed her palms to her knees, chalk dust grinding into her skin, and she tried to breathe. In. Out. But the smell of rust filled her lungs, and then suddenly it wasn’t rust, wasn’t Slough House, wasn’t rain dripping through the cracked window. It was twenty years ago.
A warehouse on the docks. A werewolf is chained and howling. Her hand shaking with chalk, her voice trembling with words she hadn’t spoken in years. And Lamb, cigarette glowing in the dark, voice slicing into her terror.
“See? That’s it. That’s power, Standish. You did that. Not me. You.”
The memory struck her like a lash. The thrill came back unbidden, just as it had then, the pulse of her will locking something monstrous in place. That surge of being more than a drunk, more than a ghost of herself. Of being indispensable.
Her stomach twisted with shame. She swallowed hard, forcing the memory down. But the vampire’s claws scraped again, its hunger spilling into her through the tether, and she felt the spark of that same old rush curling in her gut.
Lamb was watching her. Of course, he was.
“Funny, isn’t it?” he rasped, wheezing as he leaned back in his chair. “I can see it on your face. You’re remembering. That warehouse. The mutt in chains. First time in the circle... with me.”
She flinched, throat tightening.
His grin widened, cruel and knowing. “Thought I’d forgotten? Please. You were bloody incandescent. Never seen you look so alive. Still haven’t, if I’m honest.”
“Stop,” she whispered.
“Why? Afraid I’ll remind you how good it felt?” He leaned forward, smoke wreathing around his ruined face. “That’s what you’re really ashamed of, Standish. Not the spell, not the creature. The truth. You liked it. You still like it. And I...” He tapped his chest with a nicotine-stained finger. “I’m the one who gave you that taste.”
The vampire shrieked, rattling the glass, caught between fury and fear. The circle hummed hotter, tighter. Catherine’s pulse hammered in her ears.
She wanted to scream at him, to deny it, but her body betrayed her, the tremor in her hands, the heat in her cheeks, the way her heart lurched not only at the monster’s pull but at Lamb’s words.
He saw it all. He always did.
“That’s why you came tonight,” he said softly, voice dipping low, intimate. “Because you remember how it felt. Because no matter how much you tell yourself you hate me, you want to feel it again.”
The circle burned faintly on the warped boards, lines of chalk vibrating as though something beneath the floor clawed upward. The vampire slammed its claws into the window, cracking the glass with each strike, but it could go no further. Its hunger pressed against her chest like a second heartbeat.
Catherine’s throat was dry. She knew what came next... the thing she’d sworn never to do again. The spell whispered to her bones, tempting, coaxing. And Lamb, sitting too close, eyes never leaving her, stoked it like a bellows.
Her hand shook as she drew the sigil at the circle’s edge. The chalk snapped in her grip.
The vampire hissed, eyes rolling white, sensing the shift.
She bit her thumb. Blood welled, warm and vivid. For a moment she hesitated, then let it fall... one scarlet drop into the glowing lines.
The circle flared.
The vampire shrieked, body arching as though speared. Its veins blackened, its skin split, and Catherine felt it. Oh God, she felt it. Its blood wasn’t spilling on the floor; it was pouring into her. A tide of copper and ice surged through her veins, thick, burning, endless.
She gasped, staggering, nearly undone as the monster’s essence rushed inside. Its hunger slammed into her gut, its rage clawed against her ribs, its memories flashed sharp and violent behind her eyes: blood on stone, centuries of shadows, screams that tasted like wine.
She choked, swaying, and Lamb was there. His hands gripped her shoulders, anchoring her.
“Jesus Christ, Standish…” His voice was ragged, reverent. “You’re drinking it.”
Her lips parted on a broken cry. She could taste the vampire in her mouth: salt, metal, decay, and underneath it, the sweetness of stolen power. Her own blood throbbed hotter, faster, drunk on the monster’s strength.
The creature writhed, skin sloughing to ash as its lifeblood streamed into her. She shuddered, half-sick, half-alive, every nerve screaming with fire.
Lamb was entranced. “Magnificent,” he breathed. His face close, his ruined eyes gleaming like oil-slicks. “Look at you, Standish. Binding wasn’t enough, was it? No, you had to make it yours. You’ve got it in you, the rot, the hunger. You consumed it!”
Her knees buckled. The circle pulsed white-hot. The vampire gave one last keening howl, then collapsed into a plume of black ash that drifted against the cracked window before vanishing in the night.
The circle dimmed to a dull glow. Catherine crumpled forward, catching herself on her hands, sweat dripping to the boards. Her veins still sang with fire, her belly twisting with hunger that wasn’t hers.
And Lamb crouched beside her, close enough that the stench of smoke and whisky wrapped around her like a shroud. His grin was feral, his voice low, awed.
“Now that,” he said, eyes burning into hers, “was bloody beautiful.”
Catherine’s pulse hammered. Too fast. Too strong. It didn’t feel like her own anymore.
She clutched at the boards, fingernails raking grooves into the wood, as the hunger burst up inside her, ravenous, impossible. For a split second, she wanted to tear into something, anything. Her mouth filled with the imagined taste of blood.
Her body shuddered. She gasped, head snapping back, eyes unfocused, and when they did catch the candlelight, her irises gleamed too dark, too bright. Not wholly human.
Lamb froze.
He’d been leaning close, drunk on his own admiration, but now his grin faltered. The cigarette nearly slipped from his fingers. His ruined face registered something rare: unease.
“Christ,” he whispered. “Standish…”
She could feel him tense. Not because he feared the monster was still at the window, but because he feared her.
Her breath hitched on a laugh, sharp, trembling, ugly. “I can feel it,” she rasped, voice hoarse. “God help me, I can feel everything. The hunger, the centuries… all of it.”
Catherine’s fingers brushed her own skin, clammy and human and hers, and the truth hit: this body wasn’t the monster’s. It was hers.
“No,” she whispered, hoarse, guttural. “Not yours.”
The ancestral whispers stirred faintly in her ears: a chorus of old voices, half-guides, half-accusers. Some urged her to release, to burn it out. Others cackled at her weakness. She shut her eyes, ignored them all, and instead dug deep into what she knew: circles, wards, boundaries. The quiet disciplines that had always been her gift.
She drew one shaking hand across her chest, tracing an invisible sigil over her heart. Her voice, cracked but steady, shaped the words of containment, not to bind the creature outside, but to seal the remnants inside.
The hunger shrieked in her veins. Her body shook, convulsed once, then snapped taut. And slowly, agonizingly, it drained away. The foreign fire ebbed, seeping out through her skin in a fine mist that curled upward, dissipating into the cold air.
The circle was gone, the chalk ash smeared by her sweat and blood, but the air in Slough House still reeked of copper and rot. Catherine sat slumped against the wall, skin clammy, veins still tingling with the echo of something that wasn’t hers.
And Lamb, damn him, was already moving.
He rifled through a drawer that looked like it hadn’t been opened in decades, tossing out files, rusted bits of kit, what might have been a shriveled sandwich, before emerging with a squat bottle of something blacker than whisky. He lobbed it onto the desk with a thud.
“Wards’ll do bugger-all against a whole nest,” he muttered. “You’ll need these.”
Catherine blinked. The bottle’s label had peeled away long ago, but the glass still hummed faintly. Blood-oil. A black-market concoction witches used to strengthen bindings at the cost of… well, too much.
She shook her head. “Lamb...”
He cut her off, lighting another cigarette with hands still faintly unsteady. “Don’t bother. You want the bastards gone? We go in hard, we go in fast. Your circles, my blade. Between us, we’ll make ‘em regret crawling out of their coffins.”
She forced herself upright, palms slipping on the boards. “You’re assuming I’ll go at all.”
Lamb grinned around the smoke. “Oh, you’ll go. I saw you tonight. The way you drank that leech down to ash. Don’t pretend you didn’t feel it. You’re halfway there already.”
She wanted to scream at him, to deny it, but the truth sat hot in her gut. That flicker of power, that rush, it hadn’t left.
Her voice was low, almost pleading. “And what happens when it’s not the monster that gets consumed? What happens when it’s me?”
For a moment, Lamb didn’t answer. The grin slipped. He studied her, the smoke curling lazily around his ruined face, and for once, his eyes weren’t mocking but sharp, measuring.
“Then I’ll be there,” he said finally, voice rough. “To drag you back. Same as always.”
Something twisted in her chest. She hated him for saying it. She hated herself for believing it.
Lamb clapped his hands together, the sound too loud in the small, stale room. “Right, then. Nest is in the old waterworks by the river. Half-collapsed, good and rotten, full of places for the buggers to hide. We’ll need chalk, mirrors, anything sharp, and a bloody strong stomach.”
He stubbed out his cigarette and gave her that look, the one that always felt like a dare.
“You ready to show those monsters what it looks like when you’re the one calling the shots, Standish?”
The rain ticked harder against the glass. Catherine closed her eyes, breathed deep, and felt the hunger still thrumming faintly in her blood, the echo of the vampire she had consumed. It frightened her. It tempted her.
And it made her nod.
“Fine,” she whispered. “But this time… if I lose myself, you finish it.”
Lamb’s grin returned, wide and wolfish. “Deal.”
Part III
The Waterworks Nest
The river mist lay thick over the bank, swallowing sound, turning every shape into a shadow. The waterworks loomed above them, a carcass of brick and iron, half-collapsed, the tall arches dripping with moss and rain. Broken windows gaped like blackened teeth.
Inside, the stink was immediate: mildew, rot, old blood. Something scuttled across the floor in the dark, claws rasping against stone.
Catherine’s pulse rattled, but her hands were steady. She’d chalked a half-dozen sigils onto scraps of mirror glass, tucked them into her coat, and tied a length of red thread around her wrist for quick wards. The Blood Seal still lingered on her skin like a bruise.
Lamb walked half a step behind her, boots crunching softly on broken tile. He carried nothing more exotic than an old service blade and a flask. To look at him, you’d think he was just tagging along for the hell of it, but Catherine knew better. His eyes never stopped moving.
She whispered, “Remember the plan.”
“Oh, I remember.” His voice was a growl under the dripping arches. “You’re the monster. I’m just your ugly shadow. Anyone sneaks up behind, I gut ‘em. Otherwise, it’s your show.”
Her lips pressed tight. “Don’t say it like that... it makes me sound like...”
“Like what?” Lamb cut in, leaning close enough that his breath tickled her ear, whisky and smoke. “Like the thing they should be afraid of?”
Something sharp and unwanted twisted in her chest. She stepped ahead, forcing space.
From deeper in the ruin, voices murmured. Not human voices, the wet rasp of tongues not made for speech. Then laughter, cold and thin.
She touched her wrist, whispering words that made the red thread flare dimly. The air shifted. A ward went up behind them, locking the exit.
Lamb raised a brow. “Trapping us in with ‘em. Bold.”
Catherine swallowed. “Trapping them in with me.”
For a moment, silence. Then Lamb chuckled, low, delighted. “That’s my girl.”
She ignored the flush that threatened her throat. “You keep calling me that, and you’ll regret it.”
“Standish,” he corrected softly, as if tasting the name. “Better?”
Before she could answer, movement rippled through the shadows. Pale shapes slid between the arches... three, four, maybe more. Their eyes burned faintly red, catching the dim light.
One stepped forward, lips peeling back from wet, needle-like teeth. Its voice slithered out: “Witch.”
The sound coiled around her, thick with mockery. Catherine lifted her chin, though her stomach clenched. “Yes,” she said, voice steadier than she felt. “Come closer, and find out what kind.”
Behind her, Lamb chuckled again, low and wicked. “Careful, lads. She bites.”
The vampires circled. The ruin breathed with damp and hunger. Catherine drew the first sigil-glass from her coat, the shard trembling faintly with reflected light, and raised it like a weapon.
Catherine’s fingers trembled around the shard of mirror glass, but her voice, when she spoke, rang steady.
“You want to see yourselves?” she whispered.
She turned the shard outward. The sigil chalked onto its surface flared, and the vampires’ reflections screamed back at them. Not human, not even beast: warped shadows, writhing, eyeless, their mouths filled with fire. One staggered, shrieking, its claws raking its own face as the image burned through it.
Another lunged. Catherine spun, her red-thread ward snapping taut as a net of light. The creature slammed into it, convulsed, and howled as its skin blistered.
The others hissed, enraged.
“Behind you,” Lamb barked.
Catherine turned just as a pale blur dropped from the ceiling. But Lamb was already moving... not with his knife, but with a fistful of iron dust he’d drawn from his coat pocket. He flung it upward, the black grains sparkling like embers in the dark. The vampire shrieked, its skin smoking where the dust touched, and Catherine drove her mirror-sigil against its chest.
It exploded into ash.
Her breath hitched. Too easy. Too fast. And that rush… God, the rush was back, sweet and terrifying.
The remaining vampires hissed, circling tighter. One slithered close, whispering in a voice that curled like smoke: “You carry one of us inside, witch. Let it out. Feed.”
Her body shuddered, the hunger flaring in her belly, the echo of the Blood Seal twisting like a knife. Her eyes blurred, and in the shimmer of water pooled on the floor, she saw a reflection that wasn’t her own. Red eyes. A mouth too wide, too sharp.
The ancestral voices hissed in her ears. Bind them. Drink them. Claim them.
Catherine’s nails dug into her palms. “No,” she hissed. But her voice shook.
Lamb’s growl cut through the ruin: “Standish!”
Her head snapped up. He was standing firm at her back, blade out now, flask discarded. His eyes locked on hers, steady and merciless. “Don’t let the bastards write your story. You write theirs.”
Something inside her snapped.
She raised both hands, palms open. Circles of chalk and blood sigils scrawled across the floor at her command, flaring into being as if the ruin itself obeyed her. The vampires froze, caught as the bindings closed like a jaw. Their claws scraped uselessly against the light.
Catherine stepped forward, her shadow stretching unnaturally long in the candlelight. The vampires hissed, thrashing... but her voice rose, soft and terrible: “Kneel.”
And they did. Their bodies bent, forced down, writhing against her will. Ash flaked from their skin where the circles burned them.
Lamb’s low laugh echoed at her back, sharp with both awe and something more dangerous. “That’s it. That’s my bloody witch.”
The hunger clawed at her chest again, urging her to finish it with blood, to drink them down until nothing was left but power. Her lips parted, breath ragged, temptation pulling her taut.
But she remembered the aftershock, the shame, the way her veins had nearly torn apart. Not anymore.
Instead, she whispered the old words of unmaking, and the bound vampires convulsed, their pale bodies splintering into smoke and ash that scattered on the damp air.
The ruin fell silent. Only the drip of water remained.
Catherine staggered, sweat slick on her temples, chest heaving. Her hands shook, but her eyes were clear.
Lamb came up beside her, blade still wet with ash. He studied her for a long moment, then leaned close, his voice a rasp against her ear.
“Scared the piss outta me, Standish.” A pause. A grin she could feel. “And Christ, I liked it.”
Her throat closed, a tremor shivering through her body. She couldn’t tell if it was from the magic, the hunger… or the heat in his voice.
Catherine’s chest heaved with each breath, her skin slick, her veins still buzzing with the echo of the wards and blood sigils. She’d done it. And God help her, she felt magnificent.
Her head tipped back against a pillar, eyes half-closed, riding the aftershock.
Lamb’s boots scraped over the damp stone as he came closer. When she opened her eyes, he was watching her, not with mockery, not with his usual squinting contempt, but with something sharper, hungrier.
Lamb leaned in, lips almost at her ear. “You’re gorgeous when you let yourself feel it like that.”
Her whole body jolted. Because he was right. She’d liked it. The terror, the power, the control. The rush still sang in her veins. She hated him for saying it. She hated herself for wanting him to keep saying it. She turned her face away, but not far enough. His chuckle curled low and intimate in the hollow between them.
For a long, trembling moment, neither moved. The silence was heavy, charged, the ruins still humming faintly with the residue of her wards. Then Catherine forced herself upright, pulling her coat around her, putting inches of space between them. Lamb lit up a cigarette.
She thought about keeping it from him. She wanted to tell him to leave, that it was over. But instead she heard herself whisper: “They’ll know.”
Lamb tilted his head. “Who?”
She swallowed, throat dry. “The older ones. The ones who sired this nest. They’ll feel it, the breaking. They’ll smell me in the ash.” Her hands trembled as she scrubbed them against her coat. “I’ve drawn their eyes now. I’ve called them down.”
For the first time since she’d unleashed herself, fear licked cold through her chest. The kind that came with memory, from years ago, whispers in her ancestral bloodline, warnings that witches who dipped too deep into forbidden magic woke things that should never be stirred.
Lamb’s cigarette hissed out in the damp air. He ground it under his heel, face unreadable. Then he moved, not with bluster, not with mockery. Quiet. Decisive.
He checked the walls, the exits, the shadows where ash still clung. He slid the iron dust pouch back into his pocket, then drew something heavier from his coat: a short-barreled revolver, dull with age, the cylinder gleaming faintly with silver. He thumbed it open, checked the rounds. Silver shot. Enough to hurt.
Then he crouched, one knee down on the wet tile, and began sketching a warding circle himself, crude, sloppy, but recognizable. A soldier’s circle. A stopgap.
Catherine blinked. “You don’t even believe in...”
“Don’t need to believe,” he muttered, chalk scraping under his broad hand. “Just need to keep the bastards away long enough for you to do your thing.”
She stared, her chest pulling tight. Jackson Lamb, bent over chalk lines, hands steady where hers shook. Not words. Not reassurance. Action. When he finished, he sat back on his heels and looked at her. “They come for you, they come through me first.”
Her throat closed. Heat curled up through the exhaustion, through the fading hunger. Something she hadn’t let herself feel in years.
“Why?” she whispered.
Lamb’s grin was faint, half a shadow. “Because you’re bloody terrifying, Standish. And I like watching the world learn it.” His eyes flicked to hers. “You do what you do, and I watch your back.”
The silence between them hummed with more danger than the vampires had. Her body still sang with power, still trembled from the aftermath. His words, and his hands, smudged with chalk dust, rough and real, cut deeper than any spell.
Her breath hitched. The space between them seemed to shrink, drawn tight as a bowstring. He didn’t move first... just waited, as if the decision were hers alone.
She didn’t mean to move. One heartbeat, they were staring; the next, her hand had found the line of his jaw, and her lips brushed his cheek, barely a kiss, more an echo of what could have been. Lamb didn’t flinch. Just a quiet exhale, a small tilt of his head toward her touch.
Lamb’s grin deepened, quiet, knowing. “Now,” he said, voice low, “let’s see what wakes.”
