It is a great book but suffers from one small flaw, it is too long. It has clearly been meticulously researched and the author was obviously eager to show this, but it needed a serious editing to reduce it by 200 pages. For example, the author includes details of what movie some of the main players were watching on a flight back on a private jet or details of sights they saw whilst in Moscow on a trip. There are many such instances where reams of details are added in. That being said, the book is still well worth reading.
