Heavy rain lashed against the tall stained glass windows outside. Detective Vance stared down at the cold, lifeless body below. Crimson blood pooled sluggishly across the expensive Persian rug patterns. A shattered antique pocket watch lay near the victim's hand. Someone had carefully removed every single trace of valuable evidence. Midnight shadows danced wildly across the grand and gloomy library. Vance knew this twisted game had only just begun today.
