AI The last bus left Rory at the Petersham gate with brake lights bleeding red into the wet road and then nothing. Richmond Park after dark was not supposed to be open. The gates were shut and the notice wired to them said so in white on green, but the side pedestrian cut had been left ajar, its chain pooled in the grass like a dropped necklace, and her phone showed Eva's pin dropped dead center in the dark beyond it.
She stood a moment with her hands in the pockets of her delivery jacket, the Golden Empress logo still smelling faintly of chili oil and damp cardboard from the dinner shift. Her breath fogged. November air stripped the sweat from her neck. Above the black line of trees the sky over London glowed orange, too bright, too low, and then past the gate it simply stopped, as if something had put a lid over the park.
Rory had not wanted to come. Eva's texts had gone from normal to strange in the space of three messages. Come to Isolde's grove. Don't bring anyone. Don't be late. Then no answer to Rory's calls, just the pin pulsing blue in a sea of green marked Richmond Park. It was the sort of thing Eva never did. Eva over-explained everything. The silence felt borrowed.
She pushed through the gap. The chain clinked softly against the post.
Inside, the wrongness started at her shoes.
The path under the streetlamp by the gate was gravel and puddle. Ten steps in, past the first hawthorns, it turned to grass that gave under her trainers without sound. The city fell away too fast. She stopped and listened for it, for the A-road hum and a distant siren and the planes stacking over Heathrow, and found none of it. The dark here had weight . It pressed lightly on her eardrums. Her own breathing sounded too loud inside her head.
Her hair, straight and black to her shoulders, lifted at the nape. She tucked it behind her ears with cold fingers and told herself to be practical. Cool head. That was what her father always said she had, back when they still spoke without law books between them, Brendan Carter in his Dublin chambers voice, you think sideways, Aurora. It had annoyed her at Cardiff, sitting in pre-law lectures she never wanted, feeling the future narrow. It helped now. Name what you see . Test it.
What she saw was trees.
She followed Eva's pin by phone light, the beam shaking slightly over tussocks and rabbit holes. The oaks closed in, older than any trees had a right to be this close to London, trunks thick as cars, bark furred with moss. Between two of them stood the first stone.
It was not quite stone. That was the next wrong thing. At the edge of her torchlight it looked like wood turned to rock, tall as her and pitted, grain still visible where lichen had peeled away. An oak that had decided to be a standing stone. Then another beyond it, and another, a broken circle disappearing into dark. She remembered what the daytime walkers called them. Richmond grove. Isolde's grove. A story for tourists about fairies.
The air changed when she stepped between the first two stones. It warmed by several degrees against her cheeks, and the smell came up, sweet and green and entirely out of season. Wildflowers.
Rory lowered her phone. The torch caught them in patches. White stitchwort and bluebells and red campion, blooming thick in November, stems beaded with dew that should have been frost. They brushed her ankles as she moved, releasing that summer smell, too strong for the cold night. No flowers bloomed like that without reason. Her mind flicked through explanations, soil heating, city microclimate, some park experiment, and discarded each one because none of them explained the light.
There was no moon. The clouds were solid. Yet inside the circle of stones she could see . Not well, but enough . A faint, sourceless luminescence clung to the petals and to the undersides of leaves, as if the grove remembered daylight and was slow to let it go.
Her pendant warmed.
It was a small thing, thumbnail-sized, a deep crimson stone on a silver chain she kept tucked under her thermal. A man at the restaurant had left it for her weeks ago with no note, just Yu-Fei sliding the little box across the pass and saying, customer left this for the Cardiff girl, and no customer ever claiming it. Rory had meant to turn it in. She had kept wearing it instead. Now it pulsed once against her sternum, a slow throb of heat, then again. Faintly, through the fabric, she could see its inner glow redden.
She stopped dead. Her thumb found the small crescent-shaped scar on her left wrist without thinking, pressing the old white curve from a childhood fall onto a broken mug, a habit when she needed to think . Heat meant something. She did not know what, only that in the last week the stone had gone warm near the railway arches and near the service door of Silas's bar below her flat, places where the air had felt thin and leftover, and both times she had dreamed afterward of doors opening under water.
Eva, she called. Her voice did not carry. It stopped three feet out, absorbed by moss and dark. Eva?
No answer. Then a sound that should not have been there.
Leaves moving, but not in wind. There was no wind inside the stones. The high branches were still. The sound was low, at ground level, a dry shuffling through the campion to her left, deliberate, starting and stopping when she turned her head. Rory swung the phone light toward it. The beam caught only flowers nodding, stems still settling, as if something had just drawn back.
She stood very still and counted her heartbeats to slow them. Ten. Eleven. Cool-headed. Test it. Deer, she thought. Richmond had deer. A stag moving through bracken would make exactly that sound. A stag would not stop when she looked, but she told herself it might .
The pendant pulsed again, hotter.
She walked on toward the center because stopping felt worse, her trainers silent on the soft ground. The pin said Eva was here. The clearing opened, a perfect round of close-cropped grass ringed by the ancient oaks and their stone kin. In the middle the wildflowers grew thicker, a low mound of them, white in the dimness. Rory's bright blue eyes, useless in true dark, picked out too much detail anyway. Every petal edged. Every stamen. The clarity felt attentive, like the place was looking back through her own sight.
A twig cracked behind her.
She turned so fast the light smeared. Nothing. Trunks and dark and the two stones she had passed through standing shoulder to shoulder now, closer together than she remembered. She stared at the gap between them. She had walked through it easily a minute ago. Now it was a slit barely wide enough for a child. Bark groaned, very faintly, wood on stone.
That is not possible, she thought, and immediately hated the thought because it was sloppy. Find the mechanism. Erosion. Perspective. Tired eyes after a double shift. She took a step back toward them to measure and the shuffling sound came again, this time to her right, closer, a drag and lift, drag and lift through flowers that released their sweet rot smell in bursts.
Eva? she said, sharper. Stop messing about. Her voice shook on the last word and the grove took the shake and kept it.
Something moved at the edge of her vision. Not a shape so much as a cancellation, a place between two oaks where the faint petal-light did not reach. When she looked straight at it, it was only shadow. When she looked at the mound of flowers, she caught it leaning in the periphery, taller than her, too thin, its head tipped at an angle that made her own neck ache in sympathy.
Rory's mouth went dry. She clicked the phone light off because the beam was blinding her to everything outside it, and the dark rushed in and then resolved . The grove did glow, faintly. The clearing, the stones, the white flowers. And the spaces between the trees did not. They were absolute.
There were more of those spaces than there should have been. She counted oaks, lost count, counted again. Seven trunks. Eight gaps. The numbers would not settle.
The pendant burned now, a coin of heat branding through cotton. Its crimson glow bled through her shirt, lighting her chin from below. She cupped it through the fabric without thinking to hide the light and felt its rhythm change, quickening to match something else. Listening. There was a second pulse out in the dark, under the ground, answering.
Time slipped. She glanced at her phone for Eva's pin and saw 23:47. She stared at the mound, looked back, saw 23:42. Five minutes gone the wrong way. Her lock screen photo, her mum Jennifer smiling in a school staffroom in Cardiff, seemed dimmer, as if seen through water. She thought suddenly and clearly of her flat above Silas's bar, the neon buzz through the floorboards, the safety of ordinary noise, and it felt very far away, not in distance but in order, like a story she had once been told .
Rory, said the dark to her left, in Eva's voice.
Every hair on her arms rose. It was Eva's pitch, Eva's Cardiff lilt flattened by London, but empty of Eva's hurry. It said her name as if tasting the shape of it .
She did not answer. Her father's voice in her head, think sideways, and her mother's, kinder, when you are lost stay put and make yourself noticed. She did the opposite of both. She stepped backward toward the center mound, keeping her feet slow to avoid sound, eyes moving constantly, never fixing on the gaps. The flowers crushed under her heels gave up crushed honey and iron.
Rory, it said again, from behind the stones now, closer. Come on. You came all this way.
The shuffling circled. Drag and lift. She tracked it by the nodding of the flower heads in the faint light, a ring drawing tighter. Her peripheral self kept catching the tall thin cancellation, now between one oak and the next, now nearer, its head still tipped, learning her.
She reached the mound. The wildflowers there were warm to the touch when her hand brushed them, alive in a way late-autumn things should not be. The pendant jerked hard against her chest, a tug toward the ground, toward that answering pulse below. Hel portal, a word surfaced from somewhere she did not trust, Yu-Fei's late-night stories over stock pots, old words for thin places. The stone throbbed faintly with warning heat.
The light on the petals dimmed, as if a cloud had passed over a sun that was not there. The air cooled one degree, then another. Her breath fogged again. The sweet smell thinned, replaced by wet earth and cold stone.
In the new dark she understood she was not alone and had not been since the gate. The grove was full. It was full of stillnesses shaped like watchers, ringed patiently between the ancient oak stones, waiting for her to decide whether to run for a gap that was no longer there or to kneel and put her hand to the warm flowers and open what was knocking underneath.
She stood on the mound with her black hair stirring in a wind that touched nothing else, her blue eyes wide and useless and seeing too much, one thumb pressed hard into the crescent scar on her wrist until it hurt, and listened to Eva's voice try her name a third time from the dark that leaned closest, patient and certain and wrong.
