Blending scientific fact and historical accuracy, David Cerrig weaves a chilling tapestry of how events can propel men to desperate actions in the name of revenge. Once read, never forgotten. An obsessive young academic in Glasgow, consumed by hatred and haunted by murder and suicide. A radical Islamic preacher in London, branded a terrorist and deported. Exiled Algerian rebels in search of revenge against the West, by any means. Dangerous relics from the collapse of communism in the ex-USSR, abandoned for decades and almost forgotten. Together they provide the crucial ingredients for an audacious terrorist plot. An attack on a target bigger than the twin towers, which can be carried out by just a handful of men. A target which is impossible to protect and totally vulnerable. If they succeed, the effects will be devastating beyond belief. They a say little knowledge is a dangerous thing. In the wrong hands it may be sufficient... to kill a city.
