Classic french novel, first published in 1910. According to Wikipedia: "Gaston Louis Alfred Leroux (6 May 1868, Paris, France – 15 April 1927) was a French journalist and author of detective fiction. In the English-speaking world, he is best known for writing the novel The Phantom of the Opera (Le Fantôme de l'Opéra, 1910), which has been made into several film and stage productions of the same name, such as the 1925 film starring Lon Chaney; and Andrew Lloyd Webber's 1986 musical. It was also the basis of the 1990 novel Phantom by Susan Kay... He suddenly left journalism in 1907, and began writing fiction. In 1909, he and Arthur Bernède formed their own film company, Société des Cinéromans to simultaneously publish novels and turn them into films. He first wrote a mystery novel entitled Le mystère de la chambre jaune (1908; The Mystery of the Yellow Room), starring the amateur detective Joseph Rouletabille. Leroux's contribution to French detective fiction is considered a parallel to Sir Arthur Conan Doyle's in the United Kingdom and Edgar Allan Poe's in America."
