This book opens innocently, with an Arctic expedition chancing on the unexpected sight of a crashed bomber. Unusually, there is no record of any such aircraft having gone missing - the reason being that it was a secret Soviet flight loaded with weaponised anthrax that has quietly lain there for fifty years and which the Russians had hoped would never be found. The Americans, despite their well founded suspicions, agree to help the Russians to get to it, but the Russians have a second agenda, while a third party with much more sinister intent is also pursuing the aircraft wreckage. This is a well written, tense book that is in the style of the best that Robert Ludlum produced. Once started on this book, you may find it hard to do much else for a while, but consider that problem no more than the happy symptom of an excellent novel.
