Character Study/Scene Study

My character is just a rogue inspector for the FBI or some other agency but I just wish I could do a british accent for this. He is around the age of 30 and his family is normal with a son and a sympathetic wife that over-pampers him. He lives in a mansion and loves books. His motivation is just to correct his mistakes and try to be the superhero in his comic books. He's a rich man from England that loves comic books and has a huge house because of rich parents. The scene is after he quits "the agency" and he finds some other life form that he thinks is trying to take him back to the agency.
