Model response

At midnight, the clock stopped.
Then screams rose from downstairs.
I arrived before dawn, alone.
Blood darkened the library carpet.
Every window remained firmly locked.
Sir Edmund lay beneath portraits.
His fist held one match.
Footprints crossed the ashen floor.
Each trail ended beside me.
The guests watched me silently.
I had arrived after midnight.
The killer knew my name.
