Mistakenly assumed to have drowned in the Thames, John Harmon assumes a new identity to get acquainted with Mr. and Mrs. Boffin, who are next in line for his inheritance, and with Bella Wilfer, whom his father's will stipulates he must marry. Amid a vast gallery of scoundrels, strivers, and social climbers, Dickens' final complete novel explores the effects of greed and corruption, blending psychological insight with social commentary.
