The terrorist Abu ben-Zhair is on the cusp of realising his vision to destroy the West and cow the East, thereby succeeding in his avowed 'Cause of All Causes' to establish a Caliphate which rules half the world. His earlier, unprecedented threats were ignored by the global community but he succeeded in his design. He has always delivered on his grandiose promises - and this one doesn't come any bigger. He has identified one critical point on the earth's surface where one determined terrorist with resources and imagination can trigger disaster on a global scale - and he has acquired the weapon for this purpose. In the murky world of counter-intelligence, trust is a tradeable commodity and the geo-political turf wars continue while ben-Zhair moves towards his climactic attack. The story moves to a terrifying close with a catastrophic threat to the United States and Europe, and even then the international political manoeuvring continues - up to the very last seconds. Baldwin and Williams fight desperately to save the day as the covert action moves from Gibraltar to Algeria - and across the Atlantic Ocean.
