A few years ago, Peter Filkins, an award-winning translator of German, walked into a bookstore, read a few pages of an obscure German novel and recognized that he had stumbled onto literary gold. 'The Journey' was one of the 26 volumes penned by the German Jew H. G. Adler, a Holocaust survivor who sought to memorialize and understand the experience through fiction, poetry, social history, and philosophy. Filkins has now translated another of Adler's books, entitled 'Panorama.'
