Happy Birthday, Dame Agatha!
I haven't read all her stories, not even close, but I do have at least five or six of her paperbacks. I have Murder on the Orient Express, which I read after I saw the movie. It was complicated and kind of hard to keep track of everyone, but I liked it.
I also read A Murder is Announced, and I thought of that book today because of the cake, Delicious Death. Seems like that would be the perfect birthday cake for an Agatha Christie dinner party.
I like to watch the TV shows based on Agatha Christie mysteries. I think my favorite detective in her books is Poirot.
