How can one not rate an Agatha Christie mystery anything but 5 stars? And especially with Hercule Poirot as the detective. I particularly love the cleverness of his mysteries. I was fooled right up to the end. Of course, I always picture David Suchet as Hercule Poirot, which just added to my delight in reading this book. ⭐️⭐️⭐️⭐️⭐️
