Ruth Evershed arrived on the grid after getting a secondment from GCHQ. For her it was a dream come true. She always longed to get a taste of the MI5 life and she was determined to be a success. She was enthusiastic, dedicated and an invaluable member of the team. She was there to find the facts the team needed, and her research always hit the spot. Ruth was brilliant, but also completely eccentric. Her excitement at working for MI5 sometimes got the better of her, and her colleagues were sometimes rather taken aback by her enthusiasm for new projects. There was a spark between Ruth and Harry Pearce for some time. They went on a date in The Cell but Ruth ended the 'relationship' afterwards because the rest of the team knew about it and she couldn't cope with them being talked about.
