STAGIONE: 8
SINOSSI
DNA tests on a suspected robber prove his innocence but also reveal his father was an unnamed vagrant strangled on a tube train 15 years ago. The team reopens the case, going in pursuit of the victim's other family members - including the man they believe to be his brother - while Brian questions the homeless community, only to fall foul of a gang of robbers. Peter Davison (At Home with the Braithwaites) and Keith Allen (Robin Hood) guest star in the crime drama.
