 One might call it Heller’s law.Erich Heller had earlier been, famously, the co-editor of Kafka’s love-letters addressed to Felice Bauer (1887–1960), the revealing 782-page "Briefe an Felice...", published in 1967, to which he wrote an introduction that became something of a classic in itself, being retained for the French translation of the correspondence in question.Subsequently Heller also contributed an introduction to an English translation of "Der Prozess", and edited Kafka's "Der Dichter über sein Werk", and his "Über das Schreiben".
