He also published a volume on the theory of the novel and a book about the history of Hungarian literature. Given numerous chances to escape anti-Semitic persecution (as late as 1944), he chose to remain in Hungary, where his last novel, a Pirandellian fantasy about a king staging a coup against himself, then having to impersonate himself, Oliver VII, was published in 1942. It was passed off as a translation from the English, as no 'Jewish' work could be printed at the time.
