This part of the book ends with a reminder that all of these recollections swum back to our narrator because of the "fragrance" (as they would say in Combray) of a cup of tea. And, that once he had them, he would lie until morning thinking about them if he woke up during the night. It also ends with a foreshadowing of Part Two, in which the narrator references a love affair that Swann had had before he was born.
The last five pages of this fifty took me into Part Two of Swann's Way, Swann in Love. It begins with a description of the Verdurins, who seem to bring people to their "little set" and keep them their by demanding loyalty. You must agree with Mme. Verdurin that her pianist friend is the best and that her doctor is the top diagnostician. Also, you had to agree that other people's soiree's were boring or you'd find yourself out of the circle.
Swann is introduced to the circle by one of the few female regulars, Odette de Crecy. Odette has met M. Swann and thinks that it would be wonderful to introduce him to the little clan. And, so she does. I'm looking forward to reading the rest of this section, although I have to admit that at this point, I'm not a big fan of the Verdurins.
