Dark clouds gathered overhead as heavy rain began falling upon empty cobblestone streets below where nearby windows showed faint light. A lone detective stepped carefully past the yellow police tape that bordered the crime scene entrance beneath a broken streetlamp. Blood stains marked the damp wooden floorboards near heavy oak desk where the victim fell while shattered glass lay scattered. He knelt down beside the cold body and noticed a single silver key resting inside an old tattered leather jacket. A sudden whisper echoed from the shadowed corner where another figure waited patiently behind the door listening to every word.
