AI The last bus had left Rory at the edge of Richmond Park with its doors sighing shut behind her and its rear lights shrinking into the mist like two lit cigarettes pinched between wet fingers.
She stood under the dead glow of a streetlamp, hood up, one hand on the strap of her satchel and the other around the Heartstone Pendant beneath her jumper. The gem had warmed against her sternum since Hammersmith. By the time she crossed the bridge and watched the park rise ahead in a blacker bulk against the sky, it had begun to pulse .
Not fast. Not frantic.
Once every seven breaths.
Heat, fade. Heat, fade.
“Brilliant,” she murmured, looking through the iron gates into the dark. “Because this is exactly how sensible people spend a Thursday night.”
No one answered. No cyclists. No late dog walkers. No teenagers with cheap lager and speaker music. The road behind her carried the distant hiss of tyres through rainwater, but the park itself absorbed sound. Even the city seemed to draw back from it.
Rory checked her phone.
23:17.
Eva had sent three messages.
Don’t go alone.
Rory.
Answer me, you stubborn cow.
Rory typed with her thumb.
In and out. If the pendant’s reacting, I need to see why.
She stared at the words, deleted them, and slipped the phone back into her pocket. It had no signal anyway. The bars had vanished the moment she stepped beneath the plane trees leading to the gate.
The latch was cold enough to bite. It lifted without protest.
Inside, the path unfurled pale beneath the moon, a ribbon of crushed gravel bordered by grass silvered with frost. The air held that after-rain smell of mud, bark, and wet stone, but beneath it lay something sweeter. Too sweet. Flowers in a sealed room. Honey left in a dish until it thickened and drew flies.
Rory moved through the gate and shut it behind her.
The click travelled farther than it should have.
It went into the trees, struck something unseen, and came back smaller.
Click.
Click.
Click.
She turned.
The gate stood shut. The road beyond looked distant now, blurred by a low skim of fog that had not been there a second before.
“Fine,” she told the park . “Dramatic entrance. Noted.”
The pendant warmed in answer.
She followed the track north-east, then left where the path narrowed toward the old deer trails Isolde had once described with a tapping finger on a beer mat in Silas’ bar. Three turns after the split oak. Downhill until the ground sounds hollow. Never cross running water if you hear it but can’t see it.
Rory had laughed then. Isolde had not.
Now the joke sat poorly in her mouth.
Her trainers darkened with dew as she left the gravel. Grass brushed her ankles. Branches knitted overhead, their bare fingers combing the moon to strips. Somewhere far off, a stag barked once. The sound cracked across the park and left a hollow after it.
Then the hollow filled with whispering.
Rory stopped.
The whispering stopped too.
She stood with her breath caught behind her teeth, eyes narrowed into the trees. Black trunks. White fungus. A curl of bramble. A scrap of plastic snagged on a twig, twisting though there was no wind.
“Hello?”
Her voice came out flat, swallowed at arm’s length.
Nothing moved.
She took three more steps.
Whispering again.
Not words. Not quite. More like leaves dragged across stone. It came from behind, then beside her, then beneath the soles of her shoes.
Rory crouched and pressed her palm to the ground.
Cold soil. Damp grass. The tremor of her own pulse in her wrist.
The crescent scar on her left wrist showed pale in the moonlight. A childhood accident, her mother had always called it, as if Rory had tripped and cut herself on the shape of a moon. She rubbed her thumb over it until the skin warmed.
The pendant pulsed .
Heat, fade.
Heat, fade.
She rose and kept walking.
The trees changed first.
Not all at once. The oaks of Richmond Park remained oaks in the main: broad trunks, black bark split into ridges, branches crooked with age. But between them, other shapes appeared. Slim white trunks she could not name. Leaves that glimmered though winter had stripped the rest bare. A thorn bush bloomed with small red flowers no bigger than pinheads, each one turned toward Rory as she passed.
She did not touch them.
“You wanted a sign,” she muttered. “Here’s the sign. Weird murder flowers.”
A faint laugh came from the trees.
Rory’s hand went to the small torch in her coat pocket. She snapped it on and swung the beam across the undergrowth.
Wet bark. Ferns. Roots. Nothing with a mouth.
“Not funny.”
The torch flickered once.
“Don’t you start.”
It steadied, a hard white cone trembling over the pathless ground.
Ahead, the land dipped. The smell of honey thickened. The pendant pressed heat into her chest through the fabric of her jumper, no longer beating every seven breaths but every three. The silver chain prickled at the back of her neck.
She had come because the Heartstone had woken at dusk.
For weeks it had hung against her like a pretty lie, warm only when Yu-Fei’s kitchen ovens roared too high or when Rory ran deliveries up six flights of stairs and blamed her own body for the flush. Then that evening, as she had sorted change beside the Golden Empress till, the crimson gem had lit beneath her shirt, bright enough for old Mrs Singh to pause over her prawn crackers and ask if Rory had swallowed a traffic light.
An hour later, a receipt printer spat out a strip of blank paper covered in damp black letters.
THE GROVE OPENS WHEN HEL BREATHES.
No one in the restaurant had seen it happen. Yu-Fei had accused the machine of being a “cheap little bastard” and smacked its side. Rory had folded the paper into her pocket with fingers that left sweat marks.
Now, in the park’s dark throat, the words replayed with each pulse of the pendant.
The Grove opens.
Heat.
Hel breathes.
Fade.
She found the split oak.
It rose from the slope like a giant struck by lightning and left standing out of spite. Its trunk had cleaved down the centre, the two halves yawning apart to reveal a black seam within. Moonlight touched the wet inner wood and made it shine like a throat.
Rory slowed.
The seam breathed.
Once.
The movement was so slight she could have blamed shadow. The bark parted a fraction and settled back. A damp exhale rolled across her face, warm as bathwater and rank with the rot of flowers forgotten in a vase.
She stepped back.
“Nope.”
The pendant flared.
Pain flashed through her chest. She hissed and grabbed it through her jumper. The heat did not burn her skin, but it sank deeper, drawing her forward by the bones.
“Stop it.”
The Heartstone answered with another pulse , sharper.
Rory clenched her jaw , moved around the split oak, and refused to look into the seam again. The ground sloped down beyond it. The grass changed to moss. Her feet sank without sound.
The whispering returned.
This time it had edges.
Rory.
She stopped so fast her satchel bumped her hip.
“Eva?”
The trees held still.
Rory.
Not Eva. Not quite. The voice wore Eva’s rhythm the way a stranger might wear a stolen coat, buttons wrong, sleeves too long.
Rory backed toward the trunk of a tree and put it behind her.
“You’ve got the wrong girl.”
A pause.
Laila.
The name slid through the dark and touched the back of her neck.
Rory’s fingers tightened around the torch until the plastic creaked. Laila was not a name she used. Not with customers. Not with friends. It belonged to one old envelope from her father’s family, one whispered argument between her parents in the kitchen when Rory was nine, one set of documents Brendan Carter had locked away after he caught her reading them.
“You’ve still got the wrong girl.”
Leaves stirred above her. Only above her.
A branch creaked, long and wet, like something bending a joint.
She raised the torch.
A shape slipped behind the canopy.
Too thin for a deer. Too low for a bird. Pale where it should have been shadow. The beam caught nothing but a scatter of leaves that should not have been there in February: green, glossy, wet with droplets that hung beneath them like eyes.
Rory moved again, faster now, down the slope. The hollow ground gave underfoot. Each step produced a low drumbeat from beneath the moss. Not loud. Not enough to echo . Enough to suggest space below.
She remembered Isolde’s voice.
Downhill until the ground sounds hollow.
Rory kept her breathing measured . In through the nose. Out through the mouth. Panic made people stupid, and stupid people opened doors that sensible people bricked shut.
The first standing stone appeared between two birches.
It looked like oak at first glance, a thick upright slab dark with age, its surface ridged like bark. Then the torch beam caught the edge and showed stone beneath, veined with a brown grain that mimicked wood. Ancient. Not carved, exactly. Grown into shape by something with centuries to waste.
Rory approached and saw marks cut into it.
Not letters.
Antlers. Spirals. A crescent. A hand with too many fingers.
At the base, wildflowers bloomed in a riot of blue, yellow, and white, their petals open to the night. Frost silvered the grass around them but did not touch them. A bee crawled from one cup-shaped blossom to another, fat and black, wings ragged.
Rory stared at it.
“In February?”
The bee turned.
It had a human face no bigger than her thumbnail.
The torch fell from her hand.
It hit the moss without a sound, beam skewed sideways, lighting the flowers from beneath. The bee opened its tiny mouth. No sound came out, but Rory’s teeth vibrated as if a nail had scraped along them.
She snatched the torch up and stumbled back.
The bee lifted from the flower. Its wings tore in the cold air. It flew in a crooked line around the standing stone, then vanished behind it.
Rory’s pulse pounded in her throat.
“No more looking closely at things,” she breathed. “Excellent policy.”
She passed the first stone. Then the second. Then the third.
They formed a loose ring ahead, half hidden by mist, each one rising from the earth at a slight inward lean. Ancient oak standing stones. The boundary. The Grove.
The clearing within them glowed under the moon.
Wildflowers spread across it in dense carpets, their colours muted by night but still wrong in their abundance. Bluebells bowed beside foxgloves, snowdrops clustered around crimson poppies, and roses climbed over low stones with thorns like hooked teeth. At the centre stood a pool no wider than a dining table, black and still. Around it, the air shimmered as if heat rose from summer pavement.
Rory stepped between two stones.
The world behind her went quiet.
Not quieter. Gone.
No road hiss. No stag. No whispering leaves. No London hidden beyond the park. She turned, and the slope she had descended was still visible between the stones, yet it looked painted on glass, flat and unreachable. Her footprints in the moss ended at the boundary as if she had dropped from the sky.
The pendant’s heat eased.
For one breath, she almost laughed.
Then something knocked from inside the nearest standing stone.
Three taps.
Rory froze.
Three taps again.
Wooden. Patient.
She lifted the torch. The beam shook across the stone’s bark-like ridges.
Tap. Tap. Tap.
“Isolde?”
Her own voice sounded muffled, as if she had spoken through cloth.
The knocking shifted to the next stone.
Tap. Tap. Tap.
Then the next.
Tap. Tap. Tap.
Around the ring, one by one, something inside each stone knocked to announce itself.
Rory turned with the torch held out, following the sound, keeping the pool away from her back. Her satchel strap slipped down her shoulder. She shoved it up with her elbow.
“Whatever game this is, I’m not playing.”
The knocking stopped.
A child began crying somewhere beyond the ring.
Rory’s stomach tightened.
It came from the flat-painted slope behind the stones. A thin, gulping cry, the kind heard through a wall at three in the morning. No words. Just distress sharpened to a hook.
She did not move.
The child sobbed harder.
“Mammy,” it choked.
Rory closed her eyes.
Welsh lilt . Small voice. Too familiar .
Her own voice, pulled from an old family video.
“Mammy, I cut it, Mammy, look—”
Rory opened her eyes and looked at her left wrist.
The crescent scar burned white.
The flowers around her ankles leaned toward it.
Every bloom in the clearing turned, not to her face, not to the pendant, but to that little moon of old damage. Petals shivered. Stems lengthened by silent inches. The nearest bluebell brushed her boot and left a smear of pollen dark as soot.
Rory stepped away.
The flowers followed.
Not walking. Growing. Their roots pushed beneath the grass with soft tearing sounds, dragging their heads across the ground toward her wrist.
“Back off.”
She kicked at them. The stems snapped with the crisp sound of celery. A wet green smell burst up. More flowers bent. More pollen smeared her boots.
The child’s cry stopped.
A woman laughed.
Jennifer Carter’s laugh, warm from kitchens and school gates and supermarket queues, came from the pool at the centre of the Grove.
Rory did not want to look.
She looked.
The black water reflected no moon. Instead, it showed a kitchen in Cardiff: yellow tiles, kettle steaming, a chipped mug by the sink. Her mother stood with her back turned, hair pinned up, shoulders moving as she washed dishes.
“Mum?”
The figure paused.
Rory’s mouth dried.
“No. No, that’s cheap.”
Her mother’s reflection turned.
The face was wrong by inches. Eyes set too low. Smile too wide. Skin smooth as uncooked dough. It pressed both hands to the inside of the water’s surface, and the pool bulged upward like cling film under a thumb.
“Rory, love,” it crooned, though its mouth barely moved. “Come here. You’re bleeding on the flowers.”
Rory backed away until her shoulder hit a standing stone.
Something inside it leaned back.
She felt the shift through the coat: a body-sized weight pressing from within, separated from her by a skin of stone.
She shoved herself forward with a gasp.
The thing in the pool kept Jennifer Carter’s voice.
“Don’t be rude now. We raised you better.”
“You don’t get to use her.”
The pool flattened.
All the flowers bowed at once.
A sound passed over the Grove. Not wind. Inhalation.
The Heartstone Pendant flared so bright beneath her jumper that crimson light spilled through the knit and painted her hands red. The silver chain tightened against her neck. Rory clawed at it, but it would not give.
From the black pool came a bubble.
It rose, swelled, and burst without a splash.
The smell that followed belonged to a cellar after a flood: rust, old plaster, trapped air, and something sealed too long underground.
The receipt paper in Rory’s pocket grew damp against her thigh.
THE GROVE OPENS WHEN HEL BREATHES.
The pool breathed again.
This time the surface dipped inward, pulled down into a funnel. Around the rim, the wildflowers trembled . Their colours drained toward the water in thin threads, blue and yellow and red unspooling from petals into the black.
Rory’s torch died.
Darkness dropped over the clearing.
The pendant became the only light, crimson and pulsing against her chest. Each beat showed the Grove in fragments: standing stones leaning closer; flowers drained pale; mist crouched low; the pool opening like an eye without a lid.
Between pulses, something moved at the edge of vision.
Not one thing.
Many.
They stood just beyond the stones, where the world had gone flat. Tall shapes with narrow shoulders. Small shapes crouched low. Antlers without heads. Hands pressed around the gaps in the ring, fingers too long, nails clicking softly on stone.
Rory forced herself to turn in a slow circle.
“Stay out.”
The shapes stilled.
One of them answered in Brendan Carter’s voice.
“Now, Aurora, think before you act.”
Her father’s courtroom tone. Calm. Measured. The tone that had made magistrates listen and made Rory feel twelve years old with mud on her shoes.
Another voice followed. Evan’s.
“You always did make everything difficult.”
Rory’s fear changed temperature. It went cold, then clean.
She reached into her satchel and pulled out the iron kitchen knife Yu-Fei used for chopping roast duck, wrapped in a tea towel and stolen with every intention of returning it if she lived long enough for shame.
The blade slid free.
Crimson light ran along its edge.
“I left one of you already.”
Evan’s laugh came from three directions.
The hands at the stones withdrew.
The pool inhaled again, deeper. The surface pulled down until Rory saw beneath it, not water but a tunnel dropping into a red-lit dark . Heat rolled up. The Heartstone throbbed hard enough to knock against her ribs.
A whisper rose from the opening.
Malphora.
Rory held the knife with both hands.
“Still wrong girl.”
The whisper became a scrape, syllables climbing over one another in a language that made the flowers curl shut. The standing stones answered with low knocks from within, no longer patient.
Tap-tap-tap.
Tap-tap-tap.
Tap-tap-tap.
The rhythm matched the pendant.
A shape unfolded in the tunnel below the pool.
Rory saw it only in pieces as the Heartstone pulsed : a pale joint bending the wrong way; hair drifting upward though no water held it; a mouth opening where a throat should be; eyes like pinpricks pushed deep into wax.
It rose without haste.
The Grove held its breath.
Rory stepped back, heel sinking into flowers gone soft and colourless. Her shoulder brushed a stone again, and this time the thing inside pressed close enough that the surface bulged against her coat like warm flesh under bark.
A voice breathed into her ear from within the stone.
“Open, Carter.”
She swung the knife.
Iron struck the standing stone.
A shriek tore out of it, thin and furious, and the whole ring shuddered. The blade left a dark cut in the bark-grained surface. Sap oozed from the wound, black under the red light.
The thing in the pool stopped rising.
Every unseen face beyond the stones turned toward the cut.
Rory stared at the bleeding mark.
Then at the knife.
Then at the ring around her.
Her breathing steadied. Not much. Enough.
“Right,” she said, and lifted the blade again.
