Model response

The night was very dark.
Rain fell with cold drops.
He walked a lonely path.
The wind howled a lament.
A faint light glowed ahead.
He pushed open heavy gate.
The old manor stood silent.
A sudden chill gripped him.
Something shimmered on the ground.
He knelt down quickly, afraid.
A woman lay very still.
Her eyes stared at sky.
Blood stained her pale gown.
A sharp gasp escaped him.
He touched her icy hand.
She was truly gone now.
Panic flared in his mind.
He fumbled for his phone.
This nightmare just began.
