I’m sorry, it’s a full-blown obsession now.
It’s a shame I can’t actually read or speak French, because there are boatloads of Paul Féval novels available in his native tongue. But there are no English editions available that I can find, just this:
Brougham, John, 1810-1880.
The duke’s daughter, or, The hunchback of Paris : a drama, in three acts, and a prologue / dramatized from M. Paul Feval’s Le petite parisien by MM. Anicet Bourgoise and Feval as Le bossu ; adapted for the English stage.
New York : Samuel French & Son, [ca. 1883]
It’s miraculously available at the Amherst College library, but for use in the library only — it’s with the Archives and Special Collections. Foiled again!
