Steve Taylor has had his fill of the secret intelligence services. He knows from experience - and few operatives indeed have experienced what he has - that they are liable to leave their personnel in the lurch. He is sure that he will never work for them again. He is sure, that is, until one day he and his glamorous and capable partner, Vee, are injured in a bomb attack on a London restaurant. With great difficulty, Steve Taylor is persuaded back into the field. His mission? To impersonate a leading Pakistani jihadist, and thus to lead the security services to the domestic terrorists who are waiting in England to meet him. His acceptance leads to a terrifying, gripping and extraordinary operation, whose aim is nothing less than to foil a truly horrifying plan to massacre thousands of British men, women and children.
