iris murdoch's style

i notice the following motifs in iris murdoch's novel:

1. the mistress of the marriage left and the couple reunited (failed menage-a-trois)
2. homosexual relations
3. a damsel in distress (female protagonist)
4. an elderly man, who later died at the fringe of post-climax
5. comments on god (not so much on religion)
6. main protagonist is a male
7. the story is around a group of elitist, usually from oxford

(the following was written on 15/06/2010)

and that is because she is exploring the motif of 'love'.
