Model response

Rain lashed the grimy windowpane of the small, cluttered room.  A single bare bulb cast an eerie, flickering glow.  Detective Harding stared at the still, lifeless form.  The victim lay sprawled across the Persian rug oddly.  A single ornate dagger protruded from his chest.  Who would commit such a bloody, brutal act?  The air hung thick with the scent of spilled blood.  Harding surveyed every inch with a grim expression.  This perplexing case promised to be a difficult one.
