Sébastien Japrisot was a French author, screenwriter and film director, born in Marseille. His pseudonym was an anagram of Jean-Baptiste Rossi, his real name. Japrisot has been nicknamed "the Graham Greene of France".
Famous in the Francophony, he was little known in the English-speaking world, though a number of his novels have been translated into English and have been made into films.
His first novel, Les mal partis was written at the age of 16 and published under his real name (see also author profile of Jean-Baptiste Rossi).
