DC Alison Bain is a very keen, ambitious young detective who holds a passion for finding clues to fit the puzzle. Crafted and taught by Alembic, Bain has a certain tact about her which overshadows Stone's rather upfront and senseless style. Often highlighted by Turner as a well-crafted sergeant of the future, Bain has worked her way up the ranks quickly and has found herself on the murder squad after just three years in the job. The team appear to work well with her, especially Dumfries, who quite often assigns her to clean-up after Stone.
