Model response

Rain silvered Blackthorn Manor's windows.
Inside, midnight swallowed every corridor.
Detective Vale arrived uninvited, alone.
The butler's candle trembled violently.
Upstairs, Lady Marrow lay murdered.
Her pearls circled crimson silk.
A locked door mocked everyone.
No window showed forced entry.
Seven guests waited below, whispering.
Each owned a polished alibi.
Each feared the grandfather clock.
It had stopped at twelve.
