One does not think of fiction when one hears of Siegfried Kracauer, which is a shame. Most Americans who know of the man are acquainted with the two books on cinema he produced after escaping Nazi Europe for New York: the highly influential “From Caligari to Hitler” (1947) and the tome that is “Theory of Film” (1960). But Kracauer also wrote two novels, “Ginster” (1928) and “Georg” (1973, posthumous), and a handful of novellas and short stories, all of which have so far evaded the readerly radar on this side of the Atlantic.
