The clock struck midnight in the old, creaking mansion’s hallway. Detective Marla stepped inside, her eyes scanning the eerie room. Shadows danced on walls, whispering secrets no one dared hear. A lifeless body lay sprawled beside the shattered glass window. Blood pooled quietly, reflecting the dim light’s ominous glow perfectly. Outside, rain hammered the roof, drowning distant thunder’s urgent calls. Marla knelt down, noting the strange symbol carved near the wound. Suddenly, a soft creak echoed—someone else was in the house. She reached for her gun, heartbeat pounding like a wild drum. The game had just begun, and danger lurked unseen nearby.
