Kafka remarked that beyond a certain point a writer might decide to finish his or her novel at any moment, with any sentence; it really was an arbitrary question, like where to cut a piece of string, and in fact both The Castle and America are left unfinished, while The Trial is tidied away with the indecent haste of someone who has decided enough is enough. The Italian novelist Carlo Emilio Gadda was the same; both his major works, That Awful Mess on Via Merulana and Acquainted with Grief, are unfinished and both are considered classics despite the fact that they have complex plots that would seem to require endings which are not there.
