Model response

The rain fell hard tonight.
Detective Mara Voss arrived late.
Yellow tape sagged over steps.
Inside, the house smelled smoky.
Victor Hale lay motionless there.
His eyes stared at ceiling.
A glass sat beside him.
Its rim bore red lipstick.
"Nobody touch anything," Mara ordered.
Officer Dale Reeves nodded slowly.
"Who reported this crime tonight?"
The nervous housekeeper waited outside.
Mara knelt beside the body.
Her gloves snapped on quietly.
Something glinted under the sofa.
She reached for it slowly.
Then the lights went out.
Somebody had been waiting here.
