This week, BTT asks: "Favorite secondary characters? (Note the plural)."
Yes, I've got some.
But it's very late, and I've got to get some sleep tonight, so I only have time to mention one.
And actually, one of my absolute favorite literary characters is a secondary. Ariadne Oliver is a recurring character in several of Agatha Christie's Hercule Poirot mystery novels. She's a wonderfully eccentric character -- an author of mystery novels herself, and Christie's alter ego. She frequently complains about her most famous creation, the Finnish detective Sven Hjerson, just as Christie was known to complain about her famous Belgian sleuth Poirot. Mrs. Oliver (apparently a widow, although we don't really learn much about her husband in the novels) appears in only seven of the books, and a few short stories. I've always wished Christie had seen fit to let her star in a few works of her own.
