The rain fell heavily outside. Darkness cloaked the old mansion. A shadow moved silently inside. The clock struck midnight slowly. Footsteps echoed down the hallway. A door creaked open slightly. The victim lay motionless there. Blood pooled on the floor. The killer left no trace. Mystery hung in the air.
