The villagers believed her father had died trying to turn lead into gold.
They were wrong.
He had turned something else into gold, and whatever it was had followed him home.
Lily found his last notebook beneath a loose floorboard, wrapped in black silk. Most of the pages were filled with equations, strange botanical drawings, and symbols that seemed to shift whenever she looked away. The final page contained only a sentence:
When the moon is dark, do not answer the knocking.
That night, three knocks sounded at her bedroom door.
Lily lived alone.
She took a candle and descended to the cellar, where her father’s furnaces stood cold beneath a ceiling of soot. Behind the largest furnace, a narrow door had appeared in the stone wall. She was certain it had never been there before.
Something on the other side whispered her name.
She remembered her father’s hands, always stained with mercury and gold. She remembered the way he would sometimes stare at her as though trying to recognize a face he had known long ago.
Then came the fourth knock.
Lily opened the door.
Inside was a room filled with warm sunlight, though it was well past midnight. A younger version of her father sat at a wooden table, drinking wine beside a woman Lily had seen only in a single faded portrait.
The woman turned.
She had Lily’s face.
Her father smiled sadly. “You’re late,” he said. “Your mother has been waiting.”
Behind Lily, the cellar door slammed shut.
And somewhere deep beneath the house, the furnaces began to burn.
