The Old Curiosity Shop was an instant bestseller that, even while it was criticized for its sentimentality, captured the hearts of the nation with its portrayal of little Nell Trent, who is thrown into a terrifying world when her beloved grandfather is unable to pay his debts to the loathsome Quilp. Alongside the pathos of the innocent, tragic Nell are some of Dickens's greatest characters: the ne'er-do'well Dick Swiveller, the mannish lawyer Sally Brass, the half-starved 'Marchioness' and the lustful Quilp himself, a creation of demonic power and cruelty.
