Dark rain battered the cracked glass of the dusty window. Detective Miller stared down at the cold, lifeless body. Rich crimson blood pooled slowly across the expensive Persian rug. Someone had locked the heavy oak door from inside. No footprints disturbed the fresh layer of dust outside. A shattered pocket watch ticked its final dying moments away. Miller knelt beside the corpse and whispered a quiet warning. The killer was still hiding somewhere in this huge mansion.
