World at Night [EPUB ebook] 

Paris 1940. The civilised, upper-class life of film producer Jean Casson ends with the German occupation of the city. Out of money and almost out of luck, Casson attempts to work with a German film company but finds himself drawn into the dark world of espionage and double agents. More used to evading jealous husbands than the secret police, Casson beomes a reluctant spy, torn between honour, patriotism, love and survival.
