Model response

Rain hammered Blackthorn Manor as Inspector Vale arrived after midnight.
The butler opened silently, white gloves trembling above crimson cuffs.
Inside, candles guttered, revealing portraits with eyes like frozen accusations.
A violin wailed upstairs, then stopped when thunder shook windows.
Lady Harrow lay beneath the clock, pearls scattered across marble.
No blood appeared, only a violet bruise blooming darkly there.
Every guest claimed innocence before Vale asked anyone any questions.
Then the grandfather clock chimed thirteen, and someone screamed downstairs.
