The series shedding light on the inner workings of the legal system ends with a glimpse into the world of Lord Mackay, one of this century's longest-serving Lord Chancellors. How has the country's top judge fared in his battle to reform the legal system? Has the impetus for change lost momentum?
The programme also meets the colourful characters who run the Lord Chancellor's office, including the private secretary able to gauge his boss's moods and a former heating engineer who is now the purse bearer.
