The novels of Charles Dickens cover a wide range, social, moral, emotional and psychological. Thus, he is much concerned with very ordinary people but also with abnormality (e.g. eccentricity, depravity, madness, hallucinations, dream states). He is both the most imaginative and fantastic and the most topical and documentary of great novelists.

    Biographers have only since mid-20th century  known enough to explorethe complexity of Dickens' nature. Critics have always been challenged by his art, though from the start it contained enough easily acceptable ingredients, evident skill and gusto to ensure popularity.
