Awesome book, arguably the best in the Christie canon. I actually guessed the murder because of non-spoiler reviews here on Goodreads so I'm not going to say anything about the plot. However, I love mysteries and have read 100s maybe 1000s and this was one of the best, if not actually the best. It is significant that this is the only Christie book on the 1001 Books to Read Before You Die. It was the book that made her famous and generated a lot of debate at the time due to its plot. Overall, if you only read one mystery book, read this one. You won't regret it.
