Sot 4 - Trail of the Isotopes

This is the fifth addition to a fictional series that started after 9/11. The Team makes a return visit to Cuba when it is discovered that a foreign government plans to control the Island from behind the scenes after Castro's death. An assassination in London launches the Board and Team on a very complex Project that initially sends them to Europe, then on to other parts of the world while tracking Polonium 210. Suspense, intrigue and surprises fill this story, and just when you think you have it figured out, you find out that you don't.
