Model response

The body was still warm.
Detective Vale entered the room.
Blood pooled on cold marble.
Rain lashed the tall windows.
No one heard him die.
The mansion held its secrets.
She studied the dead man.
His face showed pure terror.
A locked door meant nothing.
Someone here was a killer.
Vale pulled on her gloves.
This night was just beginning.
