Little Dorrit. Riches. Book The Second

When Arthur Clennam returns to England after many years abroad, he takes a kindly interest in Amy Dorrit, his mother's seamstress, and in the affairs of Amy's father, William Dorrit, a man of shabby grandeur, long imprisoned for debt in Marshalsea prison.
As Arthur soon discovers, the dark shadow of the prison stretches far beyond its walls to affect the lives of many, from the kindly Mr Panks, the reluctant rent-collector of Bleeding Heart Yard, and the tipsily garrulous Flora Finching, to Merdle, an unscrupulous financier, and the bureaucratic Barnacles in the Circumlocution Office. A masterly evocation of the state and psychology of imprisonment, Little Dorrit is one of the supreme works of Dickens's maturity.
