Written more than 100 years ago, this was a pretty quick read. Apparently written on a bet, that Agatha Christie couldn't write a detective novel in which the reader couldn’t deduce the criminal. I was surprised, but I'm no mystery junkie :)

This is the first Hercule Poirot novel as well, following a short story written a few years earlier. Have read many reviews that say this is not the best introduction to the little Belgian - better to go back and read this later as a "prequel".

It is also in the public domain, available on project Gutenberg and better, standardebooks.org/ebooks/agatha-christie/the-mysterious-affair-at-styles which edits and cleans up Gutenberg titles. I liked it.
