What is the French novel title that Hitchcock adapted into Vertigo?

The French novel Hitchcock adapted into Vertigo was D’entre les morts.

Published in 1954, D’entre les morts was written by the French crime-writing team Pierre Boileau and Thomas Narcejac. Its English title is The Living and the Dead, and it became the literary basis for Hitchcock’s 1958 film Vertigo, starring James Stewart and Kim Novak.

The novel follows Roger Flavières, a former police detective drawn into an unsettling case involving a woman named Madeleine. Hitchcock and screenwriter Samuel A. Taylor transformed the source material, relocating and reshaping events while preserving its themes of obsession, mistaken identity, death, and the attempt to recreate a lost love.

Readers may encounter several titles for the same book. D’entre les morts is the original French title; The Living and the Dead was the first English title; and later editions were sometimes marketed as Vertigo after the film’s success. The other options are unrelated French works and are not Hitchcock’s source for Vertigo.
