This book takes what many would consider a mid level drug dealer and the search for him across the world - hence the "Marco Polo" tag. Well the villain here is not that bad so it is hard to get excited about the chase. He is no choirboy to be sure, but he is not a Pablo Escobar either. The detail of the police tactics used is interesting. The disappointing thing to me was the detail of how disjointed law enforcement is in the western world, nobody wants to work with any other countries? The book is ok and you can probably guess what happens in the end. If you are interested in this type of story, Killing Pablo by Mark Bowden is far better and more up to date.
