Mostly Guilty deals with the workings of the lowest level of the Australian legal system. It's about the down-to-earth cases that happen daily in Magistrates' Courts. It does so through the experiences and anecdotes of a low-flying criminal barrister. While the cases are from Victoria, the book makes reference to other states and has relevance and interest Australia-wide. The style is light, punchy and informal, with lots of direct speech and many funny yarns.
