Read Chapter 6: Yvonne's Sketchbook

The wind had finally died, leaving the castle in a silence so complete Isabelle could hear her own heartbeat. Rain still clung to the slate roof in heavy droplets, falling at long intervals, each one a small explosion against the stone. She stood in the east tower with the oilcloth message spread across the desk, Séraphine's words burned into her memory.

*The debt is not paid. There was another way. I was too afraid.*

Three nights until the full moon. Three nights until the sea came looking for her.

She pressed her palm flat against the wood of the desk, feeling the grain, grounding herself in the solid. The castle had stood for four hundred years. The stones had seen everything. They knew the answers. She simply had to find where they were hiding.

Corentin had taken the sea-worn box to his cottage for safekeeping, muttering something about salt and rust and things better left undisturbed. Yann had returned to his boat, promising nothing, which somehow felt worse than if he'd promised everything. Isabelle was alone again in a house full of ghosts.

She climbed the narrow staircase past the gallery, past her mother's empty space on the wall, past the locked door of the east tower room now standing open and useless. Above her, the attic stairs creaked like old bones shifting in sleep. She'd never gone up there. The groundskeeper had mentioned it only in passing—*just storage now, nothing worth the climb*—and that had been enough to make her curious.

The attic door wasn't locked. It swung open with a groan of rusted hinges, and the smell of forgotten things washed over her: dust, dried lavender, old paper. Moonlight through a round window painted a silver disc on the floorboards, and Isabelle stepped into it like a pool of water.

Boxes and trunks stacked in uneven towers, furniture draped in white sheets like figures waiting to be introduced, a broken spinning wheel. She moved through them carefully, touching nothing at first, then slowly, reverently, lifting corners of fabric and peering into boxes. Christening gowns yellowed with age. A basket of letters tied with faded ribbon. A child's wooden boat, painted and peeling.

The name stitched into the boat's hull stopped her breath: *Yvonne*.

Her great-aunt. The woman who vanished on the same full-moon night as Yann's grandfather. The woman whose portrait hung—or had hung—somewhere in the castle, removed like her mother's. Erased.

Isabelle knelt and lifted the boat, turning it in her hands. Beneath it lay a leather sketchbook, worn soft at the corners, its spine broken open at a page the way books always seem to break at the pages that mattered most.

She opened it.

The first drawings were landscapes—the cliffs at dawn, the village harbor, gulls wheeling over slate rooftops. Pretty, competent, the work of a young woman learning to see. But as Isabelle turned the pages, the drawings changed. The lines grew bolder. The subjects shifted from the world above to something half-remembered. A cove at night. A cave mouth opening in black rock. Symbols scratched in margins that Isabelle recognized from the ledger—the same angular markings, tide charts, phases of the moon inked in blue and silver.

She carried the sketchbook to the round window, sitting on a trunk where the moonlight reached the pages. Page after page showed the same cave from different angles: a wide entrance half-submerged, a shelf of rock inside like a natural altar, and on the far wall, a symbol carved deep into the stone. A spiral. Or maybe a wave breaking. Or maybe a moon with the tide pulling beneath it.

Beneath the last drawing of the cave, in handwriting that pressed hard enough to scar the paper, Yvonne had written:

*They will say I drowned. Let them. The sea has always been a good liar.*

Isabelle's hands began to tremble.

She kept turning. The final pages of the sketchbook were filled with a woman's face, drawn over and over from different angles. An older woman with sharp cheekbones and a gaze that seemed to follow the viewer from every page. Isabelle knew that face. She'd seen it hours ago in miniature, hidden inside the moonstone locket that now hung warm against her chest.

The unknown woman in the locket. Yvonne had known her. Yvonne had drawn her with something like fear in every line.

On the last page, Yvonne had written again, tiny and cramped, squeezed between drawings of the spiral symbol:

*Grand-mère said it was my duty to marry him. The Le Goffs have protected us for three hundred years, and one Marchand daughter must always marry into that line to keep the covenant whole. But I will not be traded like a cargo bond. I will not be the interest on an old debt. The sea took my mother and my sister. It will not take me.*

*I choose the cave. I choose nothing. They'll call it death, but I'll call it freedom.*

Isabelle read the words again. And again.

Yvonne hadn't vanished. Yvonne had run. She'd faked her own drowning—arranged it, perhaps, with a boat left empty and a coat set adrift. She'd gone into a hidden sea cave and disappeared into a life the Marchands never knew about. And Yann's grandfather, sworn to serve and protect the Marchand women, had followed her. Whoever had found her body had found nothing, because there was no body to find.

But then why had neither of them ever come back? Why had the grandfather's coat kept washing ashore in an empty boat, every few years, like a message no one could read?

Isabelle flipped back through the drawings, studying the cave entrance from every angle. There was something about the proportions of the cliff face that nagged at her—an architect's eye catching discrepancies in scale. She'd seen this cliff. She'd stood at its edge two nights ago and watched a golden light move on the water in the cove below.

She closed the sketchbook and pressed it to her chest, feeling the locket warm against her sternum, pulsing like a second heart.

The cave was real. It was under this headland, somewhere along the cove the villagers called the Forbidden Harbor, hidden at low tide or behind a fall of rock. She could find it. She could walk there in the morning, when the water would be out and the rocks exposed, and see for herself what Yvonne had found. What she'd chosen instead of marriage. What she'd drawn with such desperate hope in every line.

But the warning rose in her mind, unbidden—Corentin's rough voice, Yann's low and urgent: *The cove is forbidden. Stay away. The sea will come for whoever wears the locket.*

She touched the locket through her shirt. Warm. It had grown warm when the storm came, and it was warm now, though the wind had died and the sky was clear.

Yann had said the locket marked her as the one the sea would come for. But the sea had been calm all evening. The locket had no reason to burn.

Unless the sea wasn't the only thing looking for her.

Unless the cave was not a refuge but a trap.

Isabelle looked at Yvonne's handwriting again—*I choose nothing*—and wondered if her great-aunt had realized too late that some choices weren't choices at all. That running from one curse could walk you straight into another.

She tucked the sketchbook under her arm and started down the stairs, the spiral symbol burned into her memory like a brand. Tomorrow, at low tide, she would walk to the cove. She would find the cave mouth. She would see for herself what Yvonne had found and whether it could truly break what had bound her family for three centuries.

And if the sea came for her while she wore the locket?

She would make sure Yann Le Goff was there to see it happen.
