Boileau-Narcejac is the nom-de-plume of Pierre Boileau (1906-89) and Thomas Narcejac (1908-98), one of France's most successful writing duos. Boileau and Narcejac both individually received the prestigious Prix du roman d'aventures before beginning a partnership that spanned four decades, from the Fifties to the Eighties, and produced more than fifty thrillers. Their works inspired numerous films, including Alfred Hitchcock's Vertigo and Henri-Georges Clouzot's Les Diaboliques, based on their 1952 debut novel She Who Was No More.
