Strangers - Season 1 (1978)

WDC Linda Doran working as a journalist. DC Derek Willis helping out at a coroner's office. It's all part of an investigation to find out whether the death of a newspaper man was an accident or murder.

Is a uniformed police sergeant, suspected of being crooked, really guilty? Bulman poses as a copper on the beat to find out what has led the sergeant to be suspected of being 'dirty' - but finds that an ordinary policeman's lot is not a happy one.

Convinced that a local politician is taking bribes, but frustrated that his enquires have brought no results. DS Singer assigns Willis and Doran to pose as newly-weds and move into the house opposite.

When a petty crook finds a hoard of hot money and begins to receive unwanted attention from the villains who stole it, Bulman finds himself moving in with the man's family to protect him.
