Any thriller involving the KGB, the CIA and various other criminal organisations will usually be a good read. Throw in Ridley Fox, a CIA agent whose fiancé has recently been murdered, and we have a far-fetched plot involving life-threatening microbes. The plot reminded me of a James Bond movie. The author has obviously put a lot of hard work into creating all the characters, and coming up with such a complicated plot, but unless the reader can manage to take in large chunks of the story in one go, it is sometimes difficult to remember who is who and who is on whose side. I found myself having to go back a couple of pages sometimes to refresh my memory. It was a long novel, but I did manage to read it all. I was given a free copy of this book.
