Our Mutual Friend centres on an inheritance - Old Harmon's profitable dust heaps - and its legatees, young John Harmon, presumed drowned when a body is pulled out of the River Thames, and kindly dustman Mr Boffin, to whom the fortune defaults.
With brilliant satire, Dickens portrays a dark, macabre London, inhabited by such disparate characters as Gaffer Hexam, scavenging the river for corpses; enchanting, mercenary Bella Wilfer; the social climbing Veneerings; and the unscrupulous street-trader Silas Wegg. The novel is richly symbolic in its vision of death and renewal in a city dominated by the fetid Thames, and the corrupting power of money.
