Oliver Twist is Dickens' first novel, social criticism. Oliver, a rich boy, struggled in an orphanage for nine years and was sent to the coffin shop owner as an apprentice. Unbearable hunger, poverty and humiliation forced the invaders to flee to London and be forced to be thieves. He was once taken in by the rich Mr. Blair, but unfortunately he was discovered by thieves. Nancy Oliver, a kind-hearted female pickpocket, came to Blailogay to save the thief, regardless of the surveillance and threats of thieves. Oliver said that he was looking for his long-lost grandchildren. Nancy was killed by the thief's den leader, and the police immediately suppressed the thief's den. Oliver was finally reunited with his family.
