Agatha Christie Lovers discussion

as we all know, Jane Marple and hercule Poirot r Agatha Christie's most known and most beloved characters.
But A.C has written many other stories with many other detectives who r palying their rols as detectives just once and just in one book.
So,here's a question: who's ur fav char fr Agatha Christie's books(except M.M and H.P)?which book did she/he had appeard in?and why do u like him/her?

Lady Eileen Brent also known as 'Bundle'. She was fun and quirky. I think she's in two of AC's books.

i like Anita 2.she's very brave and smart.

I like Mrs Oliver

I also like Mrs. Oliver. I have recently read Hallow'en party where she is the person bringing Poirot into the story, thus plays only sort of supporting role to him. Nevertheless, her appearance enriches the story. She seems a time a bit naive, gullible, even though one would think that she should be very cautious and observant as an author of crime stories. But I guess that's her charm.

I just read the Secret Adversary. I love it that Agatha made her books such a part of history and that she tried to do the young heroes as well as the older ones.
