The clock struck midnight as rain tapped on the windowpane. Detective Harper entered the room, eyes scanning each shadowy corner. A lifeless body lay sprawled beneath the ornate chandelier’s glow. Broken glass scattered, reflecting the flickering light with eerie brilliance. Whispers of secrets lingered thick inside the spacious, silent mansion. Harper knelt beside the victim, noting the peculiar crimson stain. The chilling breeze carried faint footsteps fading down the empty hall. Only one thing was certain: this was no ordinary death.
