Wind howled outside the shattered window of the dark study. Rain washed away the bloody footprints on the wooden floor. Detective Hayes stared at the lifeless body on the carpet. Crimson liquid dripped slowly from the edge of the desk. Arthur Pendelton was wealthy enough to afford many powerful enemies. Now he lay dead beside a heavy silver letter opener. The grandfather clock chimed midnight in the completely silent hallway. Hayes knelt down to examine the victim with careful precision. A torn photograph rested quietly beneath those exceptionally cold fingers. Someone desperately wanted to hide the identity of the killer. Thunder rattled the fragile glass of the antique crystal chandelier. Shadows moved along the floral wallpaper of the grand library. The murderer was likely still hiding within this massive house. Hayes pulled his loaded revolver from his damp winter coat. He stepped slowly toward the slightly open solid oak door. Floorboards creaked under his heavy boots in the terrible silence. An unfamiliar voice echoed from the bottom of the stairs. The game of cat and mouse had only just begun.
