Marple - Poirot - Holmes Challenge

I have quite a few Agatha Christie and Arthur Conan Doyle books in my shelves, I bought them and read them when I was a teenager and always meant to reread them one day. When I found this challenge I thought it would be the perfect opportunity for doing so.

Kals of At Pemberley is hosting the Marple-Poirot-Holmes Challenge. She writes:

Nothing really beats a good old Agatha Christie mystery or an Arthur Conan Doyle masterpiece. I've loved Miss Marple, Hercule Poirot and Sherlock Holmes all my life and I doubt we'll find a detective surpassing the unexpected genius of Miss Marple, the exemplary 'little grey cells' of the Belgian detective Hercule Poirot, and of course, the master himself - Sherlock Holmes.

It's been a while since I re-read them all, which lead me to the first challenge I'm hosting - The Marple Poirot Holmes Challenge.

1. This challenge is from January 1, 2010 to December 31, 2010.
