Rain lashed against the cracked windowpane while Detective Miller stared at the dark bloodstained carpet below his heavy leather boots. The velvet curtains swayed gently in the cold draft that whispered through the shattered glass of the heavy study door. A silver letter opener rested near the pale hand, gleaming faintly under the flickering chandelier above the silent room now. Footsteps echoed down the marble hallway as Sergeant Collins arrived with his leather notebook ready and his face completely pale. Nobody heard the fatal shot ring out during the thunderstorm that battered the old mansion throughout the entire dark evening. Clues were scattered across the wooden floor like broken promises waiting for a careful mind to piece them together slowly. Murder always leaves a trace behind, and this killer certainly made several careless mistakes before vanishing into the cold night.
