Fenwick Thistleboom knocked on the mossy door for the fifteenth time, ready to promise the bog-witch the most ridiculous night of her life. This time, she answered. Not with her face, but with her voice, low and tired through the cracked wood. "There is one thing," she said. "Bring me my mother's locket, and I will walk out with you." He pressed his ear close. She told him where it lay: past the tangled roots, behind a barricade of sharpened stakes sunk into murky water. Her sisters had built it long ago to keep her in, or to keep something else out. She did not say which. Fenwick walked the short path until the bog opened wide. The stakes leaned like crooked teeth. Beyond them, half-sunk in the muck, stood the broken shell of an older tower, its stones scattered, ivy chewing the walls. That had been her home once, before the new tower, before the silence. He could see the glint of silver chain caught on a root inside. He waded in. The water bit cold up to his chest. A stake tore his sleeve and then his arm, and the red ran warm into the green. But his fingers closed around the locket. He climbed out shaking, bleeding, grinning, and turned back toward her door with the prize in his fist.

Fenwick staggered the last few steps to her door, the locket swinging from his red fist. His legs gave out. He hit the moss hard and left two long smears in the mud behind him, deep grooves where his boots had dragged. The door cracked open. She saw the silver chain first, and her face went soft and bright. Then she saw the rest of him. The blood. The torn sleeve. The way he could not lift his head. She froze. Then she moved. She rushed out with a small glowing vial clutched in her hand, the liquid inside sparking like trapped stars. Her tower stood open behind her for the first time, its foggy glass panels catching the dim light, iron frame twisted with vine and age. She knelt in the mud beside him. She did not speak. She uncorked the vial with her teeth. "You stupid man," she whispered, and tipped the light against his wound. The chapter of the closed door was over. She was outside, and her hands were on him, and neither of them could pretend otherwise now.

The vial's light sank into Fenwick's wound and the bleeding slowed. He pushed himself up on one elbow. She was already standing again, the locket lifted in her palm. Her thumb found the small catch. The silver shell sprang open with a soft click. She went very still beside the cracked glass greenhouse, its dark bottles glinting behind her shoulder. She did not breathe. Fenwick followed her eyes down to the open locket. A small bone ring sat nested inside the hollow, pale and smooth, its surface crowded with carved names. Her fingers shook. She tipped the ring into her hand and read the names twice. Fenwick saw her mouth shape one of them and stop. Above them, the tattered roof of a mossy pavilion creaked in the wind. She sank down onto its low step like her legs had forgotten her. "They kept it from me," she said. Her voice was flat and certain. She closed her fist around the ring. "My sisters knew." She looked at Fenwick then, really looked at him, and the soft brightness was gone. Something harder had replaced it. "I need to go back to that house. Tonight."

She stood up from the pavilion step with the ring closed in her fist. Fenwick scrambled after her. The bog stretched dark ahead, and somewhere past the reeds her old house waited. He had promised her a ridiculous night. This was not that night. But he fell in beside her anyway, because she was walking and he had not seen her walk before. They had not gone far when the chimes began. Rusted tin cylinders swung from a driftwood beam set across the path. They knocked together with a low, hollow song. She stopped. "My sisters hung those," she said. "They ring when anyone steps near." Fenwick squinted past the beam. Small shapes lifted from the reeds — tiny dragons with shimmering wings, circling once, then darting off toward the trees. Watchers, he understood. Messengers. "Then we don't step near," Fenwick whispered. He pointed sideways, off the path, into the black water. She frowned at him. He grinned, already pulling off his boots. "You said tonight. You didn't say the easy way." She waded in after him. They moved slow and quiet around the chimes, water at their hips. Past the beam, a wreath of rusted chain twisted with waterlogged driftwood floated across the channel — knotted thick, meant to snag a boat or a leg. Fenwick gripped one end. She gripped the other. Together they lifted it just enough to slip beneath, and the chimes behind them never sang. The house rose from the muck on the far side. Its shutters were nailed shut. Algae climbed its sinking walls. She set her hand flat against the door and breathed out, long and shaking. "I'm here," she said, to no one Fenwick could see. Then she pulled a nail from the shutter with her bare fingers. The wood gave a soft crack. They were inside the watch now, and there was no quiet way back.

Inside, the air was thick and green. Algae coated the floor like a wet skin. Lila Fen stood very still, then knelt and pressed her palm flat. "Here," she said. "Something is under here." Fenwick crouched beside her. The boards beneath the slime were warped and splintered, soft with rot. He dug his fingers into a crack and pulled. The wood came up in wet chunks. She helped him, quiet, breathing through her teeth. Beneath the broken planks sat a wooden box bound in iron, its seams packed with dried mud, its lid lashed tight with rope. "They worked at this," she said. "They didn't want it found." Fenwick took out his knife and sawed the rope. The mud cracked off in flakes. She lifted the lid herself. Inside lay a book bound in silver, its cover etched with symbols that caught the dim light and held it. Lila Fen drew a slow breath. "My mother's," she said. "They told me it burned." She lifted the book with both hands. The house seemed to lean in around them. Somewhere far off, faint and thin, the chimes began to ring on their own. Fenwick's head snapped up. "That's not the wind," he whispered. She did not look away from the book. "No," she said. "They know." She closed the box and stood, the silver book held tight against her chest. "We have what they hid," she said. "Now we have to outrun them." Fenwick nodded and reached for her free hand. The night was no longer his to shape. It was hers, and it had teeth.
