Helen West is a crown prosecutor who cares about people in the criminal justice system and seeks to ensure that justice is done. She has a particular interest in women&#39s issues and has to put up with her somewhat odd superior and his cleanliness phobia. She recognizes that it&#39s the role of the police to find the evidence but also feels it warranted to occasionally investigate matters herself. Unmarried, she is also in a relationship with Chief Supt. Bailey, though neither seem to be able to make up their minds about their futures or what they want to get out of life.
