Started reading it after hearing a lot about Christie's amazing works. I have to admit I was really bored at the beginning. It appeared banal, plain and without any substance. It changed once I reached the second part. I couldn't put down the book. My head started spinning. Never in my dreams would I have guessed the ending. The way M. Poirot deduced the facts and joined the dots was impressive. An interesting, simple yet engaging detective whodunit.
