paragraph: The driver of the Facel Vega car, Michel Gallimard, who was Camus's publisher and close friend, also died in the accident. In August 2011, the Milan newspaper Corriere della Sera reported a theory that the writer had been the victim of a Soviet plot, but Camus's biographer, Olivier Todd, did not consider it credible. Camus was buried in the Lourmarin Cemetery, Lourmarin, Vaucluse, France. He was the second-youngest recipient, at the age of 44, of the Nobel Prize in Literature, after Rudyard Kipling, at the age of 42. He was survived by his wife and twin son and daughter, Jean and Catherine, who hold the copyrights to his work. Two of Camus's works were published posthumously. The first, entitled A Happy Death (1970), featured a character named Patrice Mersault, comparable to The Stranger's Meursault. There is scholarly debate as to the relationship between the two books. The second was an unfinished novel, The First Man (1995), which Camus was writing before he died. The novel was an autobiographical work about his childhood in Algeria.
