That was awesome even if I already knew much of it for watching the TV show last year. Different from the Hercule Poirot series, maybe it had to do with me reading her in English for the first time, I was reading her in French previously, but I find it really fast pace, really fluid, closer to a thriller than an actual mystery! The schemes and imagination in the killing is unique to Agatha Christie and even more when you consider the publication date. I loved it and would recommend it, even if you're not a Agatha Christie reader, this might be a good one to "try" her.
