Heavy rain battered the deserted manor as lightning illuminated a bloodstained footprint leading toward the grand oak entrance threshold silently. Detective Isabel Hart sprinted up crumbling marble stairs, her flashlight trembling as footsteps echoed through the shadowed east wing corridors. A cold whisper slithered beneath her ear, carrying unknown menace across ancient dusty tapestries and cracked portraits hanging crookedly, silently. Sudden scream shattered hushed halls as Detective Hart steadied herself, heart pounding against ribs like frantic drumbeat of impending doom. She discovered lifeless body sprawled across Persian rug, face contorted in silent plea for justice that would finally arrive tonight.
