The storm raged fiercely outside the old mansion where shadows danced beneath flickering candlelight’s trembling, eerie glow. Detective Morgan arrived just as midnight struck, sensing something ominous lurking behind the heavy wooden doors waiting. Inside the grand hall, a chilling silence enveloped the room, broken only by distant thunder crashing violently above. On the polished floor lay a lifeless body, face pale and eyes wide with frozen terror, unmoving. Clutched tightly in the victim’s hand was a mysterious note, written hurriedly in crimson ink, ominous and cryptic. The detective knelt down, carefully examining every detail, aware this was no ordinary crime scene. Suddenly, a faint sound echoed from the darkened hallway, footsteps approaching slowly, hoping to reveal hidden truths. Morgan steadied breath before calling out, voice firm and unwavering, demanding answers from the house’s restless shadows.
