西瓜影院 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's issues and has to put up with her somewhat odd superior and his cleanliness phobia. She recognizes that it's 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.
