Oliver is an orphan living on the dangerous London streets with no one but himself to rely on. Fleeing from poverty and hardship, he falls in with a criminal street gang who will not let him go, however hard he tries to escape. In Oliver Twist, Dickens graphically conjures up the capital's underworld, full of prostitutes, thieves and lost and homeless children, and gives a voice to the disadvantaged and abused.
"Dickens is huge - like the sky. Pick any page of Dickens and it's immediately recognizable as him, yet he might be doing social satire, or farce, or horror, or a psychological study of a murderer - or any combination of these"
