The Inheritors

The Inheritors: An Extravagant Story is a quasi-science fiction novel on which Ford Madox Ford and Joseph Conrad collaborated. It looks at society's mental evolution and what is gained and lost in the process. Written before the first World War, its themes of corruption and the effect of the 20th Century on British aristocracy appeared to predict history.

In the novel, the metaphor of the "fourth dimension" is used to explain a societal shift from a generation of people who have traditional values of interdependence, being overtaken by a modern generation who believe in expediency, callously using political power to bring down the old order. - Summary by Wikipedia
