I am highly impressed with this writing duo. I was so impressed when I read The Wife Between us that I had to go on to read more of their writing and they have not disappointed! An anonymous Girl was a page Turner I couldn't get enough of but didn't want to end. I try to stay away from putting up spoilers, so for anyone who wants great plot twists and great writing this duo is it! I like the set up of going back and forth between Jessica's views then the doctor. Psychological thrillers really get into your head. What is Jessica's deep dark secrets she shares with the Doctor and how will he use this information she has divulged? What is this psychological study really about? So many questions, so many turns, so many answers to unfold!
