Third Girl is one of Agatha Christie's slower paced books. It rambles on and on about the same things over and over again. If some of the middle had been cut out, the book might have been a lot better.In the middle, I got so bored that I started counting the pages until the end. Usually with Agatha Christie, you just can't put the book down. With this one, I just wanted to finish it to find out who the murderer is.If you've read many of Agatha Christie's books, you might want to read this, but you shouldn't read this one first. I suggest The Secret Adversary for a more fast paced and exciting read.
