Trusting The Enemy

Deakin is furious when a fourth drug dealer is assaulted in a number of days, a case which Beech was supposed to be investigating. Beech enlists Lennox and the pair are soon lead to a couple of possible suspects, the O'Brien brothers. Meanwhile, Rickman is dealing with a domestic involving the O'Brien's sister, Kelly. Daly informs his friend DI Baines of area drugs about the operation, unaware that Baines is the main man and the O'Brien's boss. Beech then tries to pin corruption charges on DI Baines, keen to get one over on his rival.
