What makes this work so unusual is that it tries to mimic the format of a legal report covering a fictional trial of Pickwick, who is accused of breaking a promise to marry his mistress. In a large number of quotes from the source text, Fitzgerald explains some of the factual materials. Having some experience in legal matters, Fitzgerald can also indicate where Dickens knowledge of the British legal system is accurate and where it may deviate slightly from the true state of things.
