"I always pick up the latest Daniel Silva with excitement..."
Gabriel Allon was an Israeli spy and has a deserved reputation for daring efficiency and ruthlessness. He and his beautiful Italian wife, Chiara, are recuperating in Cornwall from his latest and supposedly last daring enterprise. They travel to London for a romantic weekend, where Allon's senses are alerted when he watches a suspicious man walking through the streets of Soho. There have been suicide bombers in recent weeks and all his instincts tell him that this is another. As he is about to eliminate the suspect (after making sure he is for real), he is stopped and arrested by plain clothes policemen. The inevitable happens.
Political constraints prevent open support for action against the threat but Allon's old allies in the American and British secret services combine with the clinical expertise of the Israeli forces to hunt down the new threat. Allon is dragged back into service and uses all his skill and charm to recruit the one person who can help. As always, the action moves quickly between New York, London and the Saudi desert before the final denouement.
