The year is 1851. It's a time of radical change in Britain, when industrial miracles and artistic innovations rub shoulders with political unrest, poverty and disease. It's also a turbulent time in the private life of Charles Dickens, as he copes with a double bereavement and early signs that his marriage is falling apart. But this formative year will become perhaps the greatest turning point in Dickens's career, as he embraces his calling as a chronicler of ordinary people's lives, and develops a new form of writing that will reveal just how interconnected the world is becoming.
