A rather sneaky one from In the Shadows of Paris (Le Léopard des Batignolles) by Claude Izner:
Kenji, clean-shaven and smelling faintly of lavender, walked past the Théâtre Français. He liked to cut through the gardens of the Palais-Royal where he communed with the departed souls of Restif de la Bretonne, André Chénier, Musset, Stendhal and Cagliostro. Could any of them tell him whether the mysterious manuscript at the Bibliothèque National was his? Lucien de Rubempre whispered to him to stop chasing after illusions and enjoy the moment.
I especially enjoyed the above since it mentioned a character rather than the author’s name. A more ordinarily found one is this one from later in the book:
‘Have you forgotten? You’re supposed to give the Balzacs and the Diderots a polish and arrange them in the window.
Another mention by Barbara Hambly!
She leaned to withdraw the folded sheets. “We follow families, names, neighborhoods for years, sometimes decades. To us, chains of events are like the lives of Balzac’s characters, or Dickens’. The nights are long.”
Traveling with the Dead (James Asher #2) by Barbara Hambly
A marvelous resource for tracking the lives of Balzac’s characters is Repertory Of The Comedie Humaine by Anatole Cerfberr and Jules François Christophe, free from Project Gutenberg.
The Lone Wolf
by Louis Joseph Vance
“My dear Count, it is useless: I am determined. Blindfold? I should say not! This is not–need I remind you again?–the Paris of Balzac and that wonderful Dumas of yours!”
I took the opportunity to snoop through his books. He hasn’t very many, but his taste is superior–Dickens, Mark Twain, Balzac, Boswell, and dear old Leigh Hunt.
The Guernsey Literary and Potato Peel Pie Society by Mary Ann Shaffer and Annie Barrows
My mother, who has read all of Balzac and quotes Flaubert at every dinner, is living proof every day of how education is a raging fraud.
