Rain stitched silver across Blackmoor.
Midnight swallowed the village bells.
At Raven Hall, candles trembled.
Detective Mara Voss arrived alone.
The butler opened, face bloodless.
Behind him, someone was sobbing.
Lord Ashcombe lay beneath portraits.
His white shirt bloomed crimson.
A chessboard waited beside him.

Mara noticed muddy footprints upstairs.

Everyone claimed it had stopped.
But somewhere, floorboards whispered softly.
