When Stamp and Rickman arrest a young man, Dougie Morgan, for possession of crack, Morgan offers to help them catch David Swain, the prime suspect behind Jamie Ross's murder. McAllister convinces Cullen to place Spears undercover as a temporary receptionist at the office of Swain's lawyer. Swain takes quite a liking to Spears and wines and dines her. McAllister, desperate for a result, pushes Spears to do "whatever it takes" to find out more. Spears comes up with the information that Swain is planning a raid on a rival crack factory, and a TSG/SO19 swoop arrests both parties. Cullen is furious when the case is dropped, due to accusations of Spears's "improper" relationship with the suspect. (thetvdb.com)
