Jack Or Knave

A security guard is murdered during a payroll snatch. The local police force under Chief Superintendent Canning have no luck in catching the robbers and Canning is reluctant to work with Regan when the Sweeney are called in, frequently clashing with him. When Regan apprehends all the gang without telling him, Canning is far from happy. Regan is accused of corruption nine years earlier and Canning, his contemporary, refuses to help him. Fortunately Carter finds someone who will, but the whole experience leaves Regan extremely bitter.
