Josh, I finished the Agatha Christie book (4:50 to Paddington) that mentions the Aga. I was hoping for much more mention! The story is good though. You can never really guess the killer in her books because it isn't based on any clues given throughout the book. She just comes up with the killer and the motive out of the blue. Got to love her anyway! I hadn't read her in years and it was fun.
The Aga gets a bit more mention in Dorothy Cannell's books, although there are some that don't mention it at all. I also enjoy the humor in DC's books. I'm going to have to get some at the library and reread them. I wonder if she has anything new out.
I love it when there's an Aga in a movie too. Did you notice the Aga in Practical Magic? The hobs were up when they shouldn't have been. I LOVED the house in that movie. It was filmed on the island where I live, altho I think they alluded that it was set in New England.
There was also an Aga in that movie a while back with Cameron Diaz, Jude Law, Jack Black, and what's her name, the actress from Titanic. Jude Law's house had the Aga. Both the English houses were cute cute cute.
