AI The gate at Sheen stood open on a chain someone had left unhooked, and Aurora Carter stepped through it with the Heartstone warm against the hollow of her throat. Richmond after midnight held the ordinary dark: wet tarmac, the iron smell of the deer fence, a sodium lamp buzzing itself towards death at the end of the lane. She had walked out from the flat above Silas’s bar because the pendant would not cool. All evening the crimson stone had pressed a small, living heat into her skin, brighter than the faint inner glow it kept in the drawer beside her bed. She had followed that heat the way a person follows a draught to the split in a window frame. West. Then south. Then off the road and into the park, until the oaks thickened and the path lost its gravel.
She knew the place from a scrap of paper folded into the lining of the box the pendant had arrived in. Richmond grove. Standing stones. Go when it calls. No signature. No second line. She had come anyway. Cool head or not, a thing that answered heat with heat wanted looking at, and she preferred to look at it before it looked at her from the doorway of her own kitchen.
The first wrongness met her at the boundary.
Seven oaks stood in a rough ring where the map on her phone showed only scrub and a ditch. Their trunks had the colour of old iron, bark split into plates, and between two of them the air changed. Not a breeze. A threshold. On the park side her breath smoked. One step past the stones and the smoke vanished. The night on this side carried the green weight of a glasshouse, damp and close, sweet with something that had no business flowering in a London January.
Wildflowers crowded the clearing. White cups, copper buttons, a low spill of blue that shone without a source. They stood open to a sky that showed no moon and no orange bruise of the city. Rory stopped with her boots in the petals and listened.
A nightjar should have been the loudest thing out here. Instead she heard water. Not the Beverley Brook. This water moved in a thin, steady thread somewhere behind the far stones, and under it a second sound: the soft click of a latch, repeated, as if a door in an empty house kept testing its own bolt.
She touched the scar on her left wrist, the small crescent, out of habit. The skin there was colder than the rest of her. The pendant pulsed once, a thumb’s width of deep red light under her coat, and went quiet.
“All right,” she said to the clearing . Her voice sat strangely in the warm air, close, as if the oaks had leaned in to keep it. “You called. I’m here. If there’s a door, show it.”
Nothing answered. The latch-click stopped.
She walked the inner edge of the ring and counted the stones again. Seven. She had counted seven from the path. She counted them a third time with her hand on each trunk, bark rough enough to catch the pad of her thumb. Six. The gap where the seventh had stood held only flowers and a darker patch of ground, oval, the size of a footprint left by something that did not wear shoes.
Rory turned her head. At the corner of her eye the missing oak was back, pale where the others were dark, its branches hung with what looked like strips of cloth . She looked straight at it. Flowers. Only flowers, and the ordinary black of the other trunks.
Her phone had no signal. The time on the lock screen read 00:41, then, when she blinked, 00:41 still, the seconds frozen between one number and the next. She put the phone away. Watched the flowers instead.
They had faces turned towards her. Not metaphor. The white cups had rotated on their stems while she studied the screen, and the copper buttons along the near edge of the path now aimed their open centres at her boots. A draft could do that to light stems. There was no draft. The leaves overhead hung without a shiver.
She took three steps towards the centre of the grove, where the ground rose in a low mound bare of flowers. The pendant warmed again, stronger, a pulse that matched nothing in her own chest. Near a Hel portal, the note had said, in a hand she did not recognise. She had not believed the word Hel any more than she believed half the things Eva texted her after two glasses of wine. Belief was not required for the stone to burn.
A twig snapped behind her left shoulder.
She did not spin. She set her weight and turned with the whole of her body, the way her father had taught her to turn in a witness box when a silk tried to rattle her: slow enough to see, fast enough not to offer her back. The clearing stood empty. The twig lay in the flowers where her own boot had not been. It was green wood, freshly broken, the pale core wet.
“If you’re selling something, the restaurant’s closed,” she said.
The joke landed and died. No laugh came back. What came back was her own last word, closed, thinned and returned from the far side of the ring a half-second late, as if the grove had to remember how to make the sound.
She crouched and touched the broken twig. Sap stuck to her finger. When she straightened, a shape occupied the gap between two oaks on her right — a narrower dark than the trunks, shoulder-height, still. She kept her eyes on the mound and used the edge of her vision the way a person uses a window while pretending to read. The shape did not sway. It did not breathe in any way she could see. It simply occupied the gap, and when she snapped her gaze onto it the gap held only night and a rope of ivy.
Her mouth had gone dry. She worked her tongue until she could speak.
“I can see you when I don’t look. That’s a rotten trick. Come out or leave me the path.”
The latch-click started again. Closer. It came from inside the mound, or from under it, a small mechanical patience. With it arrived a smell she knew from the alley behind the Golden Empress after the bins had been hosed : not rot, not yet, only the clean mineral scent of water that had stood too long in a pipe. It rose through the bare earth and curled around her ankles.
Rory set her palm flat on the mound. The soil was warm. Under the warmth , faint as a pulse in a wrist, something knocked. Once. Twice. Not an animal. The interval was too even, the way a person knocks on a door they expect to be opened from the other side.
She pulled her hand back. The crescent scar stung, a bright line of cold, and the Heartstone answered with a hard beat of light that painted the undersides of the nearest flowers red. In that brief colour she saw the prints.
They ringed the mound. Not hers. Narrower, deeper at the ball of the foot, and they did not lead in from the boundary. They began at the mound’s edge and walked outward, five of them, six, and then they stopped in the flowers directly behind the place where she stood. The last print was filling , slowly , with a darkness that was not shadow. Water. Or something with the weight of water, seeping up from below to erase the evidence of a step just taken.
She heard breathing.
Not hers. Hers was in her mouth, controlled, counted. This other breath sat a little above her shoulder, close enough that the fine hairs along her neck lifted, and it drew in when she drew in, a fraction behind, learning the rhythm. When she held her air, it held too. The grove went silent around that shared stillness: no latch, no water-thread, no late echo . Only the two breaths, and then only hers, because she had not released and the other had.
A flower brushed her calf. She had not moved her feet. The stem leaned, white cup tilted up, and in its centre a bead of crimson light wavered — the pendant’s glow, caught and kept, blinking in time with the stone at her throat.
Rory stepped sideways off the last print. The ground where she had been standing sank a finger’s depth, as if a weight had remained after she left it. She watched that depression . It did not spring back. From inside it came the small, wet sound of a mouth opening.
She lifted her chin. Bright blue eyes fixed on the ring of oaks, on the gap, on the ivy, on nothing she could hold. Her hands stayed open at her sides. The scar burned. The pendant burned. Between the two heats she stood very straight, a woman who had learned not to flinch in rooms where flinching cost her, and she spoke to the air an inch behind her ear.
“I came for the door. Not for you. If you’re between me and it, shift.”
The breathing returned, matched to hers again, and this time it spoke on her exhale. Not words. The shape of words. The cadence of her own name, Rory, pressed into the sound of air leaving a throat that was not in front of her and not, when she whipped around, behind her either. The clearing held flowers, stones, the mound, her own boot marks, and the dark oval where the seventh oak refused to stay.
At the boundary, on the park side of the ring, her breath would have smoked. She could see that colder dark through the gap, the real night, the distant tick of the sodium lamp. The path back measured longer than the path in. While she watched, one of the standing oaks on the far side took a step. Bark groaned. Roots tore free of the earth with a sound like wet cloth. It settled into a new place and was only a tree again, except that the ring had tightened, and the gap towards the lamp had narrowed by the width of a body.
Rory did not run. Running fed things that liked a back. She set her shoulders towards the mound, towards the knock, towards the heat climbing the silver chain, and she listened to the second breath settle into the space between her shoulder blades, patient, in no hurry at all, as present as the coat on her skin.
The latch clicked.
This time it opened.
