DI Adrian Dumfries serves as the male counterpart of Alembic and her competitor. Although his race added diversity to the cast, his character portrayed a 'head boy' personality. He alternates between partnering with Alembic or competing against her for control of cases while barely disguising his disregard for Stone. Despite his grandstanding, he often contributes to the solution of the mystery. In "Happy Families", he assists Turner in shifting partial financial responsibility for an out-of-control budget onto the DCI from a competing precinct. Additionally, in "Mr. Right", he separates a violent wholesaler from his family. However, for the final two episodes, his character's case contributions diminished. At the end of episode five, he cedes Alembic the crown and steps back from competing with her for case control. In "Nothing Sacred", his character's ego was heavily featured, as it became clear that he cared less about listening to a suspect than attempting to win the 'case-solver' of the week prize offered by Turner.
