Eva’s message was twenty-six seconds long. For the first nine, she breathed into the phone while something knocked on wood: twice, a pause, then once. “Richmond. Isolde’s grove. Bring the pendant. If you hear me before you see me, don’t answer.” Three more knocks followed. The call ended before Rory could hear whether Eva made another sound. She had played the message on the bus, outside the Golden Empress, and again at Richmond Park’s locked gate. Eva’s phone had refused every call since. Whoever had sent the message knew about the Heartstone, and Eva had chosen her words with care. No jokes. No apology for the hour. That, more than the knocking, had put Rory on the bus with a delivery torch in her pocket and the pendant beneath her shirt. She had left Yu-Fei a note saying where she’d gone and when to raise the alarm. At twelve minutes past midnight, Rory ducked through the gap in the railings and entered the park. Wet grass shone beyond the reach of the street lamps. Water ticked from the branches, and each step pressed a cold seep through the seams of her trainers. Richmond kept a border of city noise even after midnight: tyres on the wet road, an aircraft labouring overhead, the occasional mechanical cough of a bus. She walked until those sounds thinned behind the oaks. The first wrong thing was that she found the path. Eva had brought her to Isolde’s grove twice before. Both times they had searched for it, circling the same copse while Eva insisted the turning lay beside a split trunk. Tonight the path opened as soon as Rory raised the torch. Pale earth divided the grass without a stray root or fallen branch across it. She followed for twenty paces before she noticed the second footstep. It came after hers, faint enough to be an echo bouncing between trunks. Rory shortened her stride. The sound shortened with it. She scuffed one heel through the leaves and heard the scuff repeated from the dark on her left. She stopped and shone the torch between the trees. Rain jewelled the bark. Nothing else occupied the beam. “Eva?” Her voice travelled a short distance and vanished. Rory waited with her finger on the torch switch. When no answer came, she walked on. The standing stones emerged between the ancient oaks, their surfaces grooved and silvered by age. Roots had fastened around several of them like hands gripping furniture before a move. Beyond lay the clearing. Foxgloves stood among wood anemones; red campion flowered beneath a fringe of frost. Seasons had never meant much in the grove. That part, at least, was familiar. Tonight every flower faced the centre. Rory passed her hand above a cluster near the boundary. No breeze moved them. When she withdrew her hand, the nearest stem gave a small jerk and settled. Her phone showed no signal. The time read 00:16. She tore a strip from a yellow order slip and wedged it beneath the root marking the widest gap between the stones. Then she checked that she could see it from inside the clearing. Beneath her shirt, the Heartstone contracted with warmth. Rory pulled it free. The crimson gem rested in her palm, no larger than her thumbnail, its silver chain sliding between her fingers. A dull light turned inside it without reaching the surface. Another pulse of heat followed. She had learnt to distrust that warmth. It meant a Hel portal lay close enough for the stone to notice. She looked back along the path. The torch beam reached perhaps eight metres before the trunks took it. Eva’s warning offered no instruction for this part. Bring the pendant. Don’t answer a voice you can’t see. Nothing about what to do if the pendant began announcing a door into Hel. “Ten minutes,” Rory said. “Then I go for help.” She stepped between the stones. The temperature did not change, but the sweat along her spine turned unpleasantly conspicuous. She swept the torch around the clearing, keeping the yellow slip at the edge of her vision. No figure waited beside the stones. No phone light answered hers. “Eva? I’m at the boundary. I’ve brought it.” From beyond the nearest stone, Rory’s own voice repeated her. “Eva? I’m at the boundary. I’ve brought it.” The copy preserved the roughness in her throat after a long delivery shift. It even caught the small lift she gave Eva’s name when she was worried. It was not an echo. An echo would have returned from the stones. This voice had stood to her right. Rory turned the torch on it. Her beam struck bark, wet leaves, a fallen branch furred with moss. At its farthest edge, a flower stem straightened. Her teeth had already parted around Eva’s name. She closed her mouth. The chain tightened in her fist. She wrapped it once around her left wrist to stop the gem swinging and moved along the boundary. The warmth faded when she approached the marked gap. It strengthened when she passed the next stone. She tested the change with two paces backwards, then two forwards. Cooler. Warmer. Whatever had drawn her here had chosen the ground well. She searched without crossing the centre. Behind one stone she found a crescent of flattened grass, broad enough for someone to have sat with their back against it. She crouched and touched the blades. They were dry. Frost silvered the grass all around them, but none coated the hollow. Two knocks sounded behind her. Rory rose. The pause stretched. Then came the third. The pattern had moved from Eva’s voicemail into the clearing. She placed her palm against the stone beside her. Its grit bit into her skin. For several seconds she felt only the cold. Then a knock travelled through the rock and tapped the centre of her palm. She snatched her hand away. The stone stood silent. No crack marked it. No gap could have concealed a person’s arm. Rory wiped her palm on her coat and moved on. She had come for Eva, not to accept an invitation from the scenery. At the edge of her vision, something crossed the grass. She held the torch steady. The movement had occupied the margin where the beam faded, a brief interruption between one stone and the next. She waited. When it did not recur, she shifted one pace sideways without moving the light. A stem bowed. The one beyond it dipped next. Then a third, each bending in turn beneath a weight that left the upper air empty. The disturbance travelled six feet and stopped. Rory took another pace sideways. Nothing moved. She resisted the urge to look behind her. If the grove wanted her attention divided, it could work harder for it. She backed towards the marked gap instead, keeping the line of bent stems in front of her. The pendant pulsed again. Heat pressed through her shirt. Her phone vibrated. For one reckless instant she thought Eva had broken through. The screen showed no call, no message, only the clock. It read 03:41. Thursday had become Friday. Rory stared at the numbers until they changed to 03:42. The battery had fallen by one per cent. Her unsent message to Yu-Fei still sat at the top of the screen, waiting for a signal. She had been inside the grove for twelve minutes. Fifteen, if she allowed for the search along the boundary. Outside, more than three hours had passed. She put the phone away and looked at the yellow slip. It remained beneath the root, a small, practical square of the world she had left. Twenty paces, perhaps fewer. “Eva, I’m going for help. If you can hear me, stay away from the stones.” The words came out evenly. That pleased her until she realised she had given the clearing more of her voice to use. From the centre, Eva whispered, “Rory.” Rory’s shoulders locked. It sounded tired. Not frightened, not commanding. Tired in the way Eva had sounded after too many night shifts, when she would sit on Rory’s kitchen floor because climbing onto a chair required a decision. “Please.” Rory raised the torch and searched the centre. Flowers. Grass. The far stones. She did not answer. She turned towards the gap. One step. Two. She counted six, then stopped with her right foot raised. A seventh footstep pressed into the grass behind her. Rory lowered her foot. The faintest rustle followed, as though whatever stood there had adjusted its balance to match hers. She walked again. Three quick steps, a long one, two short. The following steps refused the pattern. They continued at an even pace, neither hurrying nor falling behind. The gap approached. Rory could see the pale path beyond it and the dark seam between two oaks where she had entered. She fixed her attention on the yellow paper. Twenty paces became ten. Five. “Rory.” Eva’s voice now came from the stone beside the gap. Rory stopped. The voice had crossed the clearing without making a journey. She looked straight ahead. “Don’t go yet.” She stepped over the root. The pendant cooled against her skin. Under her torch, the path remained where it had been, wet earth bordered by grass. She crossed onto it and listened for the next footstep. None came. Rory held her breath to sharpen the silence. No leaves shifted. No water fell. Even the knocking had ceased. She pinched her nose and sealed her lips. After four seconds, something at her back inhaled. Its exhale stirred the hair beneath her ear.
