I will admit that I tend to prefer Christie's murder mystery books to those like this, on espionage. This isn't a bad book, it's just not necessarily as good as the murder mysteries. I felt like I didn't know the characters in this book, and that I couldn't get my head around the diplomacy. I did manage to figure out who the bad guy was, which was gratifying, and it was interesting to read about Baghdad at a very different time.
