The grand clock struck midnight in the deserted mansion hallway. A single blood drop fell onto the polished marble floor. Detective Arlo found the body slumped over the oak desk. The letter opener protruded from his chest, a grotesque pin. Moonlight through the window revealed an overturned chair and papers. A cryptic note lay beside his cold, pale, lifeless hand. It held only ten words, each carefully chosen and typed. Outside, the wind howled a mournful tune through ancient trees. Detective Arlo knew this would be his most challenging case. He also knew the killer was probably still nearby, watching.
