When a leading international financier is murdered in his Beverly Hills mansion, at first it looks like just another daemon at work in the City of Angels. But when the ritual nature of the killing emerges, the FBI take an interest. And then the international connections start to emerge: the European Commission, high ranking officials in Hong Kong...and Iran. That's when the file gets passed to ODIN, and Alex Mason. When Mason starts to dig he soon realizes that the murder of a single financier is just the tip of the iceberg. Because wherever he looks, whomever he talks to, one word keeps repeating itself, and that word is 'virus'. In a case that will take him and Gallin half way round the world to the Pyrenees in France, London and the Chilean Andes, they will both realize the terrifying truth that this is no ordinary virus. This is on the brink of madness. This virus is Satan's Revenge...
