Oliver Twist, subtitled The Parish Boy's Progress, is the second novel by English author Charles Dickens, published by Richard Bentley in 1838. The story is about an orphan, Oliver Twist, who endures a miserable existence in a workhouse and then is placed with an undertaker. He escapes and travels to London where he meets the Artful Dodger, leader of a gang of juvenile pickpockets. Naïvely unaware of their unlawful activities, Oliver is led to the lair of their elderly criminal trainer Fagin.

Oliver Twist is notable for Dickens's unromantic portrayal of criminals and their sordid lives.[1] The book exposed the cruel treatment of the many orphans in London during the Dickensian era. The book's subtitle, The Parish Boy's Progress, alludes to Bunyan's The Pilgrim's Progress and also to a pair of popular 18th-century caricature series by William Hogarth, A Rake's Progress and A Harlot's Progress.
