We see the detritus of an abandoned camp in South America and a main character's hallucination. Then, the story beings. Tony and Brenda Last, lord and lady, live on his enormous estate with their young son. Tony's not much for parties, and Brenda joins London society, on the arm of a penniless man, John Beaver, a hanger-on at Tony's club. John is encouraged by his entrepreneurial mother, who sees a quid in Tony and Brenda. Brenda and John become lovers, Brenda spends more and more time in London, and Tony's without a clue. Then, bringing things to a head are tragedy, law suits, greed, and what should be a few-months' expedition to Brazil. We are each of us merely a handful of dust.
