AI By the time Aurora reached the old oak stones, the park had gone hollow.
Richmond after dark never felt entirely empty. Even in the quieter reaches there was usually some reminder of the city pressing at the edges—a distant road hiss, a plane needling through cloud, the occasional laugh carried too far on cold air. Tonight the dark seemed to have swallowed all of that. The night sat over the grove like a lid.
She stopped just short of the nearest standing stone and checked her phone out of habit. No signal. The screen reflected her own face back at her in a pale blur: bright eyes sharpened by nerves, black hair dragged loose by the wind, the line of her mouth set harder than she felt. Twenty-three past eleven.
“Fine,” she muttered, and put it away.
She hadn’t come here on a whim. The note shoved under her flat door that afternoon had been written in a cramped hand on thick cream paper, expensive and old-fashioned enough to feel ridiculous. If you want answers about the pendant, come alone to the grove in Richmond Park at midnight. Wear it.
No signature. No explanation. Just that.
Under any sane set of circumstances, Aurora would have binned it and changed the lock. But sane had been slipping for weeks. Ever since the pendant had turned up in a plain velvet box with no sender, ever since she’d noticed how it warmed under her shirt in places no warm metal should, ever since she’d started catching impossible glimmers in shop windows and puddles—doorways where there should have been brick, shadows moving against the grain of the light.
So she had come.
The Heartstone lay against her sternum now, suspended from its silver chain. Even through her jumper she could feel it: a low, animal warmth , stronger than it had ever been in the city. Not hot. Not yet. Just awake.
The standing stones ringed the entrance to the grove in a rough crescent, each one half-swallowed by moss and roots. Ancient oak trunks rose behind them, black and massive, their branches knitted into a ceiling that let through only shreds of moonlight. Wildflowers grew in dense drifts at their feet despite the season—foxglove, bluebells, white things she didn’t know by name. In daylight the place might have looked enchanted. At night it looked staged, too perfectly strange, as if someone had assembled every detail to suggest safety and magic while forgetting that real woods breathed and shifted. These did not. They waited.
Aurora stepped between the stones.
The temperature changed at once. Not colder exactly. Closer. The air pressed lightly at her skin, damp as breath. She took two more steps and the sounds of the wider park dropped away completely , so abruptly it made her stop.
No traffic. No wind in the grass. No owl. No fox bark. Nothing.
The silence had grain to it. It hummed against her ears.
She turned slowly, trying to place the path behind her. The standing stones were still there, but farther than they should have been, as though the clearing had stretched while she wasn’t looking . The moonlight pooled oddly between the trunks, making distances unreliable. A flat patch of wildflowers opened at the grove’s heart, silvered pale. Beyond it, oak boles crowded together in a ring.
“All right,” she said softly, because hearing a human voice in all that stillness helped. “I’m here.”
No answer.
Of course not. Anonymous notes rarely came with punctual hosts.
Aurora folded her arms against the chill and waited.
A minute passed. Maybe five. Time felt slippery here, the way it did when she was overtired , each second either dragging or dropping clean out from under her. She became aware of tiny details with painful clarity: the dampness seeping through the soles of her boots, the sweet overripe smell of flowers, a thread of metal on the air like old coins held too long in the hand.
Then she heard leaves rustle behind her.
She turned at once.
Nothing. Only the nearest oaks, broad trunks furred with moss. Their branches hung motionless. The wildflowers around them did not stir.
Aurora held her breath. The pendant pulsed once against her chest, a faint throb of warmth .
“Hello?”
Still nothing. Yet the feeling had shifted. The grove was no longer empty in the casual way of ordinary places. It was occupied in the way of a room after someone has stepped inside and stopped moving.
She forced herself to walk toward the center of the clearing. The flowers brushed her boots. Their petals looked bruised in the moonlight, colors drained toward grey. Halfway across, she had the distinct impression that something moved just beyond the trees to her left—not a shape exactly, more a rearranging of dark. She snapped her head around and caught only the afterimage of motion, too fast and too slight to fix.
Fox, she told herself. Deer. Richmond Park was full of deer.
But deer made sounds. Hooves shifting. Breath steaming. The crack of twigs under weight .
The grove remained hushed.
Aurora reached the middle of the clearing and stopped. Her left wrist itched beneath her sleeve, right over the small crescent scar she’d carried since childhood. She rubbed it absently. The skin there felt cold.
Somewhere off to her right came a soft click.
Not a branch. Too neat for that. Like a fingernail against stone.
Then, after a pause, another. Closer.
Aurora turned. Moonlight glazed the line of standing trunks. One of them seemed thinner than the rest, bent at an angle no tree should grow . She squinted. The bent shape was gone . There was only an ordinary oak with a split in its bark.
Her mouth had gone dry.
“This is stupid,” she whispered, though whether she meant the note, the grove, or her own decision to come, she couldn’t have said.
She took out her phone again and thumbed on the torch. The beam carved a narrow white lane through the clearing. Flowers leapt into color at its edge—blue, crimson, ivory—too vivid, almost wet-looking. She swept the light over the trees.
At first she saw nothing unusual. Bark. Roots. A tangle of fern.
Then the beam struck a shape low to the ground behind one trunk: pale and rounded, about the size of a face.
Aurora jerked the light back.
It was only a cluster of mushrooms grown fat and white from the wood.
She exhaled through clenched teeth. “Get it together.”
The words vanished into the dark without an echo .
That was wrong enough to make her still. In woods, even quiet ones, a voice should bounce, however faintly. Here her own speech seemed absorbed the instant it left her mouth, as if the grove drank sound .
The pendant grew warmer.
Aurora tucked the phone into her palm and laid her fingers over the gem through her jumper. The Heartstone answered with another pulse , stronger this time. It had done that before, near odd places in the city—a derelict alley in Whitechapel where the air had smelled of snow in July; the basement of a shuttered church in Deptford where she’d heard whispers behind a locked wall. Hel portals, someone had called them in a conversation she’d not meant to overhear downstairs at the bar. Gates. Thin spots.
If there was one here, then the note had not been random.
A breath touched the back of her neck.
Aurora spun so hard her boot skidded in the damp earth. The phone torch swung wild, striking trees, flowers, stone.
No one stood behind her.
But the flowers in a strip a few feet away were bowing , one after another, as if something unseen were moving through them. Not wind. There was no wind. The motion tracked with intent, a line curving around the edge of the clearing. Slow. Deliberate.
Watching her.
Aurora backed away before she knew she’d decided to move. Her heel hit one of the low roots and she caught herself. “Who’s there?”
This time the silence that followed felt almost amused.
The bent flowers stilled.
Then, from the trees ahead of her, came a sound so soft she might have mistaken it for memory: a woman humming under her breath.
The tune was unfamiliar. Three notes descending, then rising one short step and stopping. It had the shape of a lullaby but none of the comfort. It came again from farther left, then from behind her, then somewhere near the stones at the entrance as though whoever made it could cross the grove without passing through the space between.
Aurora’s scalp prickled. She turned in place, trying to catch a source. Every time she thought she had one, the hum shifted. Not louder. Closer.
The phone torch dimmed suddenly , bright beam collapsing to a dirty yellow. Battery at sixty percent, she thought stupidly. It shouldn’t—
The light steadied. Then dimmed again.
The pendant was hot now. Not enough to burn, enough to insist. Through the fabric she could feel the tiny shape of it as clearly as if it were pressed to bare skin, and beneath the heat something stranger: a tug, subtle but constant, drawing her attention toward the far side of the clearing where two oak trunks twisted together like clasped hands.
The humming ceased.
In its absence Aurora heard another sound. Breathing.
Not hers. Too uneven. Wet at the edges, dragged shallowly in and out as if through a damaged throat.
It came from between the twinned oaks.
She should have left then. Sensible people did not investigate invisible singers and impossible breathing in midnight groves. Sensible people did not cross into places where time went wrong and silence ate echoes . But she had not come all this way to bolt at the first proof that the world was stranger than she wanted it to be. Fear narrowed her thoughts into hard practical lines. If something was here, then seeing it might be better than imagining it.
Might.
Aurora lifted the failing torch and walked toward the trees.
Each step felt observed. The flowers no longer brushed her boots. They recoiled before contact, stems bending away. The air thickened until drawing a full breath took effort. Her pulse beat in her throat.
Five paces from the twinned trunks, the phone died altogether.
Dark slammed in.
For one blank second panic rose clean and sharp. Then her eyes adjusted enough to make out the silver spill of moonlight and the darker columns of oak. The pendant shone faintly through her jumper now, a dim red seep like banked embers.
The breathing stopped.
Aurora did not.
She moved one more step and saw, between the roots, a space where there should not have been one. Not a tunnel. Not a hollow. A seam in the night itself, narrow and vertical, darker than the surrounding dark. Its edges trembled as if cut through water. Looking at it made her eyes water and her stomach knot. The Heartstone burned against her chest.
A portal, she thought, and the idea landed whole.
In the seam’s shifting blackness something stood just beyond sight. She could not make out features. Every time her gaze tried to settle, they slid away. A figure only by the logic of outline—too tall, too thin, a concentration of absence with the suggestion of limbs folded close.
Then it moved.
Not through the seam. Around it.
It stepped from behind the oak where no body had been a moment before, and the moonlight touched enough of it to ruin sleep for the rest of her life.
It was shaped like a woman in the broadest sense: head, shoulders, arms hanging long and loose. But the proportions were wrong, joints uncertain, as if copied by something that understood the arrangement of a human body without grasping how it should fit together. Its skin—or what passed for skin—held the pale flatness of mushrooms under bark. No features showed clearly, only hints: a blank slope where a face ought to be, a dark slit that might have been a mouth. Its hair drifted around its head not with wind but with underwater motion .
It stood very still.
Aurora stood very still too. Her breath made no visible cloud. Her hand had found the pendant and closed around it hard enough that the silver chain bit her fingers.
The thing tilted its head.
Somewhere deep in the grove, impossibly far and impossibly near, the three-note hum began again.
The figure’s mouth opened.
When it spoke, the voice that came out was her own.
“Aurora,” it said softly from that featureless face. “You came alone.”
Every muscle in her body locked. Hearing her voice out there, detached from her chest and given back to her emptied of warmth , was worse than the sight of it. The words were exact. Even the Cardiff flattening on the first syllable. Perfect and dead.
Aurora made herself answer, though her tongue felt too thick. “Who sent the note?”
The thing did not move closer. It did not need to. The grove had already shrunk around her, every tree leaning inward in her peripheral vision though they stood straight when she looked directly. The pendant throbbed in her fist.
“Not sent,” it said in her voice. “Asked.”
“By who?”
A pause. Then, with delicate precision: “By the one who wants what was given.”
Its head dipped toward her clenched hand.
The Heartstone flared hot, a sharp pulse that lit the red gem through wool and skin alike. For an instant the grove flashed into terrible clarity. Aurora saw the seam between the trees widen like a pupil. Saw more shapes standing beyond it, stacked in impossible depth. Saw prints in the damp earth all around the clearing, not animal and not human, as though many narrow feet had paced circles around her while she waited. Saw, nearest of all, that the figure before her cast no shadow in the moonlight.
The red glow died back.
Aurora took one step backward.
The thing matched it with one step forward, smooth and silent.
“Don’t,” she said.
Again, that faint tilt of the head. Curious. Listening.
Behind her, from the direction of the standing stones, came a distinct scrape of stone on stone.
Not one sound. Several.
As if the boundary markers at the grove’s edge were shifting in the dark, closing ranks.
