Model response

The rain fell hard tonight.
Detective Mara Voss arrived late.
Blood pooled beneath the desk.
Victor Hale lay motionless there.
Nobody had touched the letter.
Its wax seal was broken.
Mara knelt beside the body.
Her gloves snapped on quickly.
A window stood open nearby.
Cold wind swept the carpet.
Someone fled in haste tonight.
Mara noticed the muddy footprints.
They led toward the hall.
Officer Dan Reyes stepped inside.
"Anyone we know?" he asked.
Mara didn't answer right away.
Instead she read the letter.
Its final words chilled her.
"Tell no one," it read.
Mara looked up at Reyes.
Someone in this house lied.
The killer was still here.
