Born in Nice, France, Justine Dubois is noted for her misanthropy and consequently prefers the company of women. She is skilled in smuggling, surveillance and stealth, and is multilingual, speaking French, English, German and Italian. At the professional level, she acts as a useful bridge between her uncle's criminal enterprise, her brother's connection to the Deuxième Bureau and the vast European smuggling ring into which she has inserted herself. Justine serves as James Bond's initial contact in the Alps and uses her family's connections to assist him in his search for a key linked to bio-terrorist Whar Zin. She points him in the direction of Anaelle Brouchard, who was given the key by her jealous 'friend', Ludovic de Baleine.
