Bonjour Tristesse

French true first is unambiguous: René Julliard, Paris, 1954. The census hypothesis that John Murray (UK) precedes Dutton (US) appears reversed for the English translation: the Dutton (New York) edition was published early 1955 and ran to four printings within February–March 1955, while the John Murray (London) edition is recorded later in 1955 (reviewed in The Times, 19 May 1955) — so the US edition most likely precedes in English. Both English editions carry the same Irene Ash translation and are collected.
