Fog settled over silent street. Crime scene beyond iron gate. Distant siren pierced midnight quiet. Solitary figure watching shadows creep. Dripping blood stained marble foyer. Heavy footsteps echoed through halls. Candlelight flickered against portrait frame. Forensic gloves held curious locket. Detective Caldwell surveyed gruesome carnage. Faint whisper suggested family secrets. Moonlight glinted off shattered glass. A hush fell upon mansion. Tension lingered in stale air. Someone whispered justice before dawn. Clue hidden beneath broken chandelier. The investigation was only beginning.
