Model response

Night shrouded the old mansion.
Rain lashed the dark windows.
Silence felt very heavy.
Detective Harding moved very quietly.
He held a bright flashlight.
Harding saw dark dancing shadows.
Something felt profoundly wrong here.
He found the grand library.
A still figure lay there.
Blood stained the Persian carpet.
The blood was dark red.
Mrs. Davies was quite dead.
Her wide eyes stared back.
Fear gripped Harding suddenly.
A cold chill enveloped him.
He grabbed his police radio.
"Help needed here immediately."
This night changed all lives.
