If you are like me, you had a slightly difficult time with the first two volumes of this series. I am not sure if it's because I have become somewhat acclimated to the writing style. Yes, there still are a few tedious digressions, but they are fewer and shorter. Thus, I do not think it is just me.
In the first two volumes, the reader has only heard about the Guermantes, who were universally regarded as the wittiest and most fashionable family in the land, especially the Duchess. In this volume, Marcel, who by this point, is in his early twenties, somehow fulfills a life long dream of getting an invite to this supposed heaven on earth. It is unclear how the invitation came about (initially, he concieved the idea to stalk the Duchess on her morning walks, to the point where she was clearly annoyed by him). However, the change probably started at a salon of his best friend's aunt, Madame Villeparisis.
Though a washed up wild-child with literary ambitions, who flouted convention to the point where none of the "best" people would be caught dead at her house; she had some success with the less stuffy aristocrats who had nothing to lose, like her cousin Duchess herself.
All the truly great ladies had one relative to whose house they could go to slum with politicians, artists, and writers. For whatever reason, it was probably seeing Marcel at this interesting gathering, along with the endorsement of his best friend, that made the Duchess change her tune enough to invite him to one her "dinner parties."
These contrasting party-scenes, read almost like the script from an episode of Absolutely Fabulous. However, Marcel's image is tarnished as he realizes that even these illustrious personages engage in nothing but scurrilous gossip and are mostly "illiterate" when it comes to literature.
It seems that 99% of their talk is hair splitting on who has a legitimate claim to a particular title (and everyone is a "cousin" even if they cannot find a common ancestor more recent than Louis XI). While a lot of this stuff was kind of lost on me, it's not hard to infer the significance if you have some clue about the Revolutionary and Napoleonic periods. The action is set during the Dreyfus affair, which, like Trumpism, was just as polarizing in that people avoided the topic in mixed company).
Of course the Duchess liked to think of herself as someone who is "modern" and open minded, unlike the Courvoisiers, her close cousins who are stuck in the 1600s (though a snob like everyone else, she truly is more intelligent and well-read than most others of her class). However, she was prone to do and say things just to be a "king mixer," like praising someone's collection of really tacky-sounding Empire furniture which was universally loathed. However, because the Duchess liked it, everyone else claimed they loved it too.
The other funny thing was how she and her husband, who despised one another, nevertheless relied on one another in a good cop/bad cop way to draw out from the Duchess (who was the master of the put-down), all of the stories that in turn gave people something to repeat at their dinner parties; thus cementing their reputation as the gayest place to be.
Though disillusioned, Marcel realizes that he can get a lot of material to write about and has no intention of staying away from these people, as long as he never allows himself to truly believe that anything they say is sincere (they do seem like a bunch of gas-lighters). I don't know if the next volume picks up where this one left off, but for once, I actually wanted more. However, I will not say anything because it gives away too much of the story.
