Model response

Rain stitched the manor windows as midnight swallowed the moor.

Inside, the guests laughed too loudly, avoiding the silent hallway.

Detective Vale arrived late, carrying mud, a notebook, and dread.

At the foyer, a vase lay shattered beside fresh blood.

No one admitted hearing screams, though everyone watched the clock.

When the host vanished, the storm sealed every possible escape.

Vale smiled thinly, because murder had already begun before dinner.
