Last night in my reading, the Duke and Duchesse of Guermantes were at loggerheads because she was a Dreyfusard and he was not, and be blamed her politics for his not being named president of The Jockey Club. Here is a link to a letter from Proust on the topic of Dreyfus, a very divisive period in French political/military history.

The Duchesse de Guermantes has a wardrobe full of Fortuny dresses which she says would be suitable for Albertine. Lucky girl.
