I found this piece of undeniable literature very difficult to read. The focus was on the characters, thus making most of the action cerebral rather than physical.
Patrick White gives us his usual sad description of elderly spinster Theodore, who comes from a sheltered but difficult background. After living a life of servitude, which seems to be self inflicted, she launches herself into the wide open world so that she may find truth... I think! Truth(?) is not something a person 'finds' which Theodore eventually discovers.
I could not really understand what she did find, unless it was absolutely nothing. I think I would interpret White's novel as being about how quests for particulars tend to be fruitless and are inclined to end badly. But probably there are many other interpretations of this novel which would be equally as valid as mine.
I could not recommend this novel for the average reader because it is so dense. But those who enjoy prose as poetry and peculiar characters well described (and almost, but not really believable) might find this tale enjoyable - even if it has to be taken in small bites!
