A Dickensian theme and a Jamesian theme in The Princess Casamassima

As noted in yesterday's post, Henry James's "The Princess Casamassima" feels in some ways more Dickensian than Jamesian, and this holds true through the first 4 chapters (60 pages or so), as in the 3rd, the dressmaker, Mrs. Pynsent?, takes the 10-year-old boy, Hyacinth (!), to see his mother, who is dying in prison and about whom he knows nothing. She tells him the woman wants to see a young boy because she never sees children in prison, and she had a son named Hyacinth as well (one of so many boys named Hyacinth) - the boy is obviously disturbed by this visit, and his elderly mother just keeps saying in French "he hates me" or words to that effect - which he cannot understand. James gives a very good and amazingly creepy description of the prison (Newgate?) and it effect on the whole section of London (Battersea?), a section of the novel steeped in gloom and despair. Then we jump forward in time, without warning, in the next chapter - Pysent is now quite elderly and the neighborhood urchin girl (Henning?) whom we'd glanced earlier returns for a visit - now she's a fashionable but still working class and kind of "cheap" - and wants to see her childhood friend, whom she calls Robinson (good thing) - so clearly their relationship will develop, and James has established the very Dickens-like story line of characters chafing against their social class and the very Dickensian (and Jamesian) story line of characters ashamed of their humble origins. I imagine his treatment of this theme will be very Jamesian (not Dickensian), but we'll see.
