PC Klein is offered the position of partnership officer, but he is shunned by the relief, who think he grassed Smithy up to get the job. Sgt. Cryer has a funny feeling about Frank Kennedy, and decides to do some digging of his own, and he encourages Smith to do the same. With Klein's help, Smith infiltrates the gang of youths intimidating the local residents, and discovers that the real estate firm Mather & Devine is indeed behind the harassment . Meanwhile, Cryer uncovers the fact that Kennedy was a notorious East End gangster named Ken Franklin who stored weapons for the Kray brothers, and that Kennedy's claim of shooting in self-defence is disproven by the forensic evidence and a statement from the other gang member. Smith is re-instated, Supt. Chandler approves his transfer to SO19, and Klein turns down the partnership officer job.
