Visions of Jean Dupart - Jenkins's gradual disillusion

First a bit of a surprise to me - I knew some of what I was reading in Anthony Powell's Dance to the Music of Time seemed out of sequence, and as I looked at some plot summaries of the 12 volumes I realized that I had skipped volume six, The Kindly Ones, which I'm now reading, and read the subsequent volume - well, it shows how this work is kind of a pastiche and you can jump around in it maybe not in random order but at least without strict adherence to publication chronology. Anyway, part 3 of The Kindly Ones ends with the bringing together in Albert's seaside b&b a # of the characters that had appeared in different parts of this narrative - notably Dr. Trelawney, and an old and attenuated man, his current partner Mrs. Eldridge, who had previously spent time with the late Uncle Giles, and of course Peter Dupart (?) former husband of the narrator's lifelong crush, Jean Dupart. This section doesn't move the story along very significantly, but it's a chance for Jenkins, the narrator, to get some very unsettling information about Jean, including her involvement with a # of sordid and unattractive men - J. started off by stiffly disliking Dupart, perhaps in part out of sexual jealousy - how could she ever have married him? - but ends up bonding with him to a degree over many drinks and accepting the info he provides as truthful - maybe it is, we don't know at this point - about Jean, seriously discoloring his memory of her, his longing for her - maybe a good thing, too, as he is now married to Isobel - who I think is expecting a child, if I remember? Everything that happens in this volume is colored as well by the gradual approach of war and the general fear of Hitler, or air attacks, and great puzzlement in England as to whether England should aggressively resist Nazi power - and of course the war profiteers, Donner and Widmerpool, move forward in their slimy way.
