Drugs are dealt openly in the pub. When the hospital phones to tell him that his wife, Kath, is dying, Harry is too late to see her one last time because he is too scared to take the quicker underpass route, where a gang holds court. His wife is laid to rest next to the grave of their thirteenyearold daughter, Rachel, who died in 1973.After her funeral, Len confides in Harry that he is being terrorised by some youths and shows Harry an old bayonet he now carries to defend himself, saying that the police would not help him and he plans on taking justice into his own hands. The next day, Harry is visited by Detective Inspector Alice Frampton Emily Mortimer and Detective Sergeant Terry Hicock Charlie CreedMiles, who tell him that Len has been murdered by a local gang. The leader of the gang, Noel Winters Ben Drew and his gang members Carl Jamie Downey, Dean Lee Oakes and Marky Jack OConnell are arrested for the murder, but released due to lack of evidence. After Lens funeral, Harry is held at knifepoint by Dean, who intends to rob him. Harry stabs Dean with his own knife in selfdefence during a brief struggle. Frampton visits Harry again the following morning and informs him that because Len was killed with his own bayonet, any charges could be reduced to manslaughter on the basis of selfdefence. ........
