The maturation of Dickens's style in Little Dorrit

I may be wrong but it looks to me as if Charles Dickens is working toward a new (for him), introspective literary style in Little Dorrit; previous novel, Bleak House, went about as far as CD could go in social satire, with its comic and at times tragic vision of "Chancery," the interminable court proceedings and the impenetrable legal machinations that drives people to penury or insanity. In LD he takes the satire to another step, this time focusing on the abuse and corruption in the court system, with particular focus on the Circumlocution Department, whose function is to provide sinecures and to slow or derail every inquiry from the public. Though the office itself its CD's creation, the process still feels contemporary to many who seek information, let alone redress, from public officials and agency. Whereas in BH the characters' confrontation with Chancery leads to several long passages and set pieces on the abusive system, in LD the thoughts of those who get entangled in the issues of the debtors' prison are more personal and more revealing of character, in a way I think unique in CD's work up to this point. One fine set piece occurs (about 25% through the novel) when the protagonist, Arthur Clennum, reflects on why he was correct in declining to declare his love for "Pet" Meagles - he sees himself as unworthy of her, in fact unworthy of the love of any woman - an incredibly sad passage - and then, looking out on the river flowing by, he has what would later be recognized as a kind of epiphany, thinking about the eternal flow of the waters and finding that soothing, but in an unexpected way - the waters, he recognizes, are oblivious to pain. So as he looks out and thinks he indirectly conveys to us his pain and sorrow, which he could never express directly, and it's as close as he can come to an admission that he should have declared his love to Pet, and that his failure to do so at the right moment may have locked him into a sorrow and loss and self-denigration for the rest of his life. Of course we also suspect that he will find redemption and love, most likely with the title character, Little (i.e., Amy) Dorrit - whom at present he sees as too young and declasse for his love interest - but that may change.
