This carries on a story from the previous episode where Frank went to the police station with a young man called Barry who is accused of stabbing a man with a screwdriver.
The good news for Frank, DC Broome knows someone who is looking for an enquiry agent.
Frank is wary at first but relishes the opportunity. It is better than stacking supermarket shelves.
Frank's first case involves Barry. The man who he is stabbed died. Barry is accused of murder, his solicitor's wants to go for manslaughter.
Barry's father is wealthy and is prepared to pay heavily for witnesses to perjure themselves. Frank first checks out if the dead man had a violent past.
Suddenly it is like watching a different show. No more Frank moping about, with his suit on, doing what he knows best, he is a different man.
The story about Barry is an old chestnut. The privileged son with an overbearing, rich and successful father.
