Gentleman Jim is the 1200th episode of The Bill.
Despite having only recently rejoined the Met, W.P.C. Blake is placed on attachment to C.I.D., much to the envy of the relief. D.C. Carver, behind on his paperwork, is far from pleased when Blake drags him around Sun Hill following up leads on a trivial car theft case. Their investigations, however, lead them to a gang of armed robbers.
