Fog crept across deserted grounds. Shadows danced along silent hallways. A scream echoed through night. Detective Mallory arrived by taxi. He scanned each ominous corner. A flickering candle threatened darkness. Blood stained the marble floor. Footsteps echoed down empty corridor. A lifeless body lay motionless. Cold wind whispered through halls. Murder had returned to home.
