She walked on ahead of him, scrunching on the shingle beach that wound between the bank and mud where the water was seeping inwards. A roosting seagull whirled up ahead of them with an unearthly call, and he followed her shadow over shingle and mud and the driftwood, hearing the steady hiss, as the sea, somewhere out in the darkness to his right, came constantly closer, flooding mudbanks, drowning the reeds, always coming unstoppably on.

She scrambled up another bank to a path that ran higher, above the tidemark, and he followed her between gorse bushes where the nighttime flowers were drained of their color and glowed silver rather than gold, but he could still smell their honey scent on the air. An owl hooted near him and made him start as he saw it, dark in the darkness, wheeling away on wide silent wings.

They walked for a long time, until the pack on his back became heavy and he felt as if he were in a dream, following the wooden heels of her pattens, the dirty hem of her skirt, through a world that had lost meaning as well as color, on a winding track through desolation. He pulled himself up, and whispered an “Ave Maria,” reminding himself that he was honored to carry the word of God, the precious objects for the Mass, and a ransom for a king; he was glad to have to struggle on a muddy path through an unmapped shore.

The sea seeped farther inland as if it knew no boundary. He could see the water creeping through the driftwood and straw on the shingle below them, and on the other side of the bank the ditches and ponds were swelling and flowing back inland as if it were, as she had said, a place that was neither sea nor shore but the land itself that ebbed and flowed with the tide. He realized that for some time he had heard a strange hissing noise overlaying the sound of the lapping water, like the seething of a giant stewpot, like the bubble of a kettle.

“What is that? What is that noise?” he whispered, stopping her with one hand on her shoulder. “Do you hear it? A terrible noise! Strange, like the water is boiling.”

She halted, quite unafraid, and pointed out into the middle of the moving water. “Oh, that. Look, there, out there, in the mire, can you see the bubbles?”

“I can see nothing but waves. God save us! What is it? It sounds like a fountain?”

“It’s the hushing well,” she said.

He was absurdly frightened. “What is it? What is that?”

“Nobody knows,” she said indifferently. “A place in the center of the mire where the sea boils as it comes in. Every high tide, so we pay no attention. Sometimes a stranger takes an interest in it. A man told my brother it was probably a cave, underneath the mire, and the bubbles pour from it when the sea fills it. But nobody knows. Nobody’s ever seen it.”
