Model response

Fog clung to the cobblestones like a damp, cold shroud.  Detective Harding surveyed the grim scene with tired eyes.  A lone streetlamp cast long, dancing shadows near.  Mrs. Gable lay still, a tragic, silent tableau.  Crimson stained her pristine, expensive silk blouse.  Her eyes stared wide, a silent, horrified question.  The air hung heavy with the scent of decay.  A single, delicate porcelain teacup shattered near.  Someone had wanted her gone, very, very badly.  Harding sighed, another puzzle, another life ended.
