Ruth is the Bright Young Thing in MI5’s top secret Section G surveillance team. She knows that, if she does her job properly, one day she can impress enough people and be running the whole department. Unlike most of her MI5 colleagues she has got to where she is on basis of ability rather than the Old School Tie. This ability has been sorely tested in the past, but experience has taught her to not get mad, but to get well and truly even. Remember, she’s watching. Politicians beware!
