Strangers

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.
