Interesting 3rd part in series. You might want to rent Molloy then Malone Dies then The Unnameable...then they will make sense.
I love Beckett but his language doesn't work well (for me) on the audiobook format. Too many rewinds to listen again and again. For me its much better read.
Martha Dow Fehsenfeld was authorised to edit Beckett's correspondence in 1985.
