Detective Miller pushed open the heavy wooden door and stepped inside the grand hallway where the dead body rested quietly. The cold rain drummed against the tall windows while the inspector examined the scattered papers upon the wooden desk carefully. A golden pocket watch lay open near the victim where the tiny second hand had stopped at midnight precisely then. Dark stains spread across the white shirt as the doctor leaned closer to examine the fatal wound upon the throat. A single black rose rested upon the table where the final clue waited patiently for the careful investigator to notice.
