The third of six programmes in a series which sheds light on the legal system.

Last year the Law Society received more than 20,000 complaints about solicitors, many from people shocked by the size of their bills. Reporter David Rose investigates how solicitors calculate their costs, including the practice of "uplift", which enables lawyers to bump up their bills for everything from thinking about a case to having an idea while at home in the bath. Posing as a customer, Rose tests the willingness of solicitors in Derby to talk about money and meets a local bus driver who has taught himself law and offers legal advice for free.
