Strangers

Day one: While Willis investigates a jewel robbery. Bulman and Doran track villains who are systematically beating up nightclub hostesses. The two enquiries lead in one direction and the team ultimately find themselves working together on the same problem.

Bulman and Willis find themselves investigating the theft of a postman's mailbag. A straightforward case? Not when their enquiries point to something fishy afoot.

Assigned to investigate a betting racket, Bulman takes a job in a betting shop, while Doran finds employment as a professional gambler. It isn't long before the detectives discover a link to the horse-racing world.

As Doran goes undercover as a journalist, Willis helps out at a coroner's office. It's all part of an investigation to find out whether the death of a newsman was 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. Singer assigns Willis and Doran to pose as newlyweds and move into the house opposite.

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