Chapter 5
Chapter 5 — "The Climax of the d'Anconias"
TL;DR: The San Sebastián copper mines that Francisco d'Anconia built in Mexico turn out to be a worthless hoax that ruins his investors and the People's State of Mexico, prompting Dagny to confront the man she once loved at his Manhattan hotel suite — where the laughing playboy hints he destroyed his own empire on purpose.

Summary: News breaks that Francisco d'Anconia's vaunted San Sebastián copper mines, in which Mexico has now nationalized the operation and into which James Taggart routed his railroad's investment, are barren and worthless — the equipment shoddy, the ore body essentially nonexistent, the entire project an elaborate fiasco. Investors are wiped out; the People's State of Mexico, having seized the mines, finds itself owning ruin; the Taggart San Sebastián Line, which Jim built to serve the project, is suddenly worthless track. Dagny — stunned that the most brilliant man she has ever known could be responsible for so stupid a failure — drives to the Wayne-Falkland Hotel to confront him. Long passages of flashback braid through the chapter: their childhood summers together at the Taggart estate on the Hudson, Francisco's prodigy intelligence, his teenage labor at every job in the railroad and the d'Anconia mines, the moment they became lovers, and the inexplicable day, years ago, when he turned overnight into a worthless international playboy and abandoned her without explanation. In his suite she finds him relaxed, mocking, and unrepentant; he tells her he meant the San Sebastián mines to fail in exactly this way, and refuses to say why.
