First I do think that author is very talented and I have really enjoyed of that I have read by him. This book, I enjoyed as well, though, I don't feel I can give the book a 5 as I of do judge of the authors books. I have to give this book a 3, nearly a 4. Why? Well, and I think I could be wrong, but I felt the main character was able to befriend people way to easily. In fact, way too convenient. The girl helping him, the family helping him, and a person who works for the Foreign Office using phones that may or may not secure.
Okay, so this is my thought. People became this mans friend too easy. They trusted him. I thought this was off. I didn't think it was feasible. Though I must admit, he was in the a different county, where that may be more feasible. I live in the US and that just may not work. So I could be wrong. However, I also think about James Bond and in those flicks, he was able to get help of others. Things just happened for him.
My other point, when our main character spoke on the phone with his best friend who was living the double live. He just demanded to have a question answered. There was no rationale for it.
Other than that, I thought the book was good. In some ways it makes me think of Honor Among Thieves, though that book was written many years latter.
Well, that is a enough, I don't want to bad mouth the guy. But I do think if you are like me, pretentious about things you will find a book has some big feasibility holes.
