‘Krapping away here to no little avail,’ writes Beckett to the actor Patrick Magee in September 1969. To ‘no little avail’, note, not to ‘little or no’: there is a difference. It’s the difference that Beckett makes — I can’t go on, I’ll go on, and all that. This final volume of Beckett’s letters contains much krapping away to both no little and little or no avail.
