In which we meet Arthur Less, novelist, approaching his 50th birthday, ex lover of renowned poet Robert Brownburn, and avoiding attending the wedding of his current ex - Freddy Pelu. What does Arthur do? he schedules a weeks long multi country tour to make sure he is far away during the big event.
These two blogs summarize Less better than I can.
I do like Arthur - and will read more of his adventures.
