Model response

Rain lashed the dark street.  Shadows clung to cobblestones.  A lone figure walked swiftly.  Their cloak billowed in wind.  They clutched something tightly.  A door creaked open then.  Footsteps echoed in hall.  Silence swallowed the night.  A struggle ensued briefly.  Gasps were quickly stifled.  A thud shook the floor.  Stillness returned to room.  Darkness held its secrets.
