No Offence - Season 1 Episode 2

Dinah is taken off the murder case as her involvement with Cathy has made her too subjective but Viv asks her to assist when a student is found dead in the street of an overdose and drugs expert Miller directs the team towards a house suspected of being a drugs factory. Angelina Costeros, a former chemical factory employee, is brought in but refuses to incriminate likely co-defendant Jensen Raphael until Dinah and colleague Spike unite to get her to talk. Consequently Dinah and Joy go undercover to bust Raphael. The operation is successful and Viv praises the two women to McLaren as well as suggesting that Dinah be reassigned to Cathy's case in the hopes that she can get her to give more information about her abductor.
