Lucy Moore, in The Thieves' Opera, has explored an interesting topic that takes the reader through the world of London from the slums to, on occasion, the mansions. Using the characters of Jonathan Wild and the folk hero/criminal Jack Sheppard, the author expands the narrative to show the entire world of crime and punishment that existed at this time. Very little seemed, at times, to separate those committing the crimes from those prosecuting the criminals and it is easy to see why Jack Sheppard, with his numerous escapes, could become such a hero in such a corrupt system. The story is told in a way that leads the reader from the beginnings of a system that would lead to crime to the execution of the criminal. The two lead criminals sometimes fall by the wayside in their own story but interest is maintained nonetheless by looking at the larger canvas. An interesting read.
