RILE
A job, a favor for the Queen. But protecting this young, sexy spitfire, is frustrating, as she parades around half-naked and ready for anything. But it's a job, I have to stay focused on the mission, not her body. When her safety is threatened, my sixth sense kicks in. With her life on the line, I realize, it's so much more than a job.
