I liked The Paris Key. It turned predictable and I was somewhat annoyed by some repetitive descriptions of locksmithing and the questioning tone at the end of several chapters. I also found there were too many characters without enough character development. However, I had a taste of what living in Paris could be like. I must say that this book appealed to me at first because the book jacket was so beautiful. I would give it 3 1/2 stars so I rounded up to 4.
