This is the ''Penguin English Library Edition'' of ''Little Dorrit'' by Charles Dickens. 'You talk very easily of hours, sir! How long do you suppose, sir, that an hour is to a man who is choking for want of air?'. A masterly evocation of the state and psychology of imprisonment, Little Dorrit is one of the supreme works of Dickens' maturity. 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, a man of shabby grandeur, long imprisoned for debt in the Marshalsea. As Arthur discovers, the dark shadow of the prison stretches far beyond its walls to affect many lives, from Mr Panks, the reluctant rent-collector of Bleeding Heart Yard, to Merdle, an unscrupulous financier. ''The Penguin English Library'' contains 100 editions of the best fiction in English, from the eighteenth century and the very first novels to the beginning of the First World War.
