This serial was possibly the worst I have watched for years. In the last episode, the interview between the police and Rebecca was so just like an amateur dramatic play in a small village hall with the policeman waiting for a prompt from the wings.
Also, if Rebecca worked on a newspaper somewhere on the coast of England, why did all the cars have Irish number plates??
As for the FLO, how she deduced exactly what had happened from one knife, she must have used a crystal ball!
