The rain hammered against the old mansion’s windows as Detective Harper stepped through the creaking front door cautiously. A lifeless body lay sprawled across the tiled floor, blood pooling beneath the victim’s head in a chilling pattern. Shadows danced eerily on the faded wallpaper, casting sinister shapes that made Harper’s heart race with uneasy suspicion. A shattered vase lay nearby, its ceramic pieces glinting like tiny daggers reflecting the dim candlelight flickering softly. Silent footsteps echoed from the upstairs hallway, suggesting the murderer might still be hiding somewhere within these haunted walls.
