Classical Agatha Christie. Amazing plot twists and easy to follow. There's lots of misogyny and classism. At least this one does without the overt antisemtism that you find in other books of her. I am looking forward to the new reworked versions that don't display so much discrimination. because I do very much like her writing style and thrilling storyline. Until then I cannot give more than 3.5 because the book's language just not timely anymore.
