Model response

Rain lacquered the windows of Blackthorn Manor, while Inspector Vale stepped through the door, carrying suspicion like a second coat.

Inside, the chandeliers glowed over a silent dinner table, where one place remained set, and one glass held blood still.

Mrs. Alder, the hostess, whispered that her husband had vanished before midnight, but the servants noticed his study light afterward.

Vale found no footprints in the mud, only a shattered watch, ticking beside the conservatory door like a warning there.
