I admit that at first I really hooked. I expected to follow the investigation of a husband to find his wife and I found myself in the middle of a rather ordinary hostage .... Then, the more we advance in the reading and questions are piling up. So, despite some a little too "big", despite explanations quite unusual, I left up in the game and I was eager to know the result. And a nice surprise arises at the end and I like myself conducted by boat left by the author throughout a book ;-) Too bad the end is so fast shipped. Too bad this "happy end" so perfect that does not exist in real life .... But overall it remains a book to recommend.
