Faceless Strangers (Silent Witness)

When the beautiful wife of a local MP is found naked and murdered in their home, the entire resources of the Cambridge Constabulary are brought to bear. But when the decomposed body of a homeless drug addict is discovered it is an entirely different matter. Police resources are stretched and there is no money left to deal with the case. Nevertheless Detective Sergeant Stanley Sharman is determined to solve the murder and approaches Dr Sam Ryan, now working independently in Cambridge, to help him. Between them they form an uneasy alliance, working together to track down the killer of a girl without a past and without an identity.
