What was the subject of matter for Charles Dickens?

Gifted (or burdened) with a strong sense of justice, Dickens always wrote with social and personal injustice in mind. Examine everything he wrote and a protest or expose of a social wrong (the class system, the judicial system, etc.) will be apparent. He primarily used London was his 'canvas' (even when the book begins somewhere else), because it provided such fertile ground for the illustration and denouncement of the ills of the world.
