Gabriel Allon is back in Venice, when a terrible explosion in Rome leads to a disturbing personal revelation: the existence of a dossier in terrorist hands that strips away his secrets, lays bare his history. Hastily recalled home to Israel, drawn once more into the heart of a service he had once forsaken, Allon finds himself stalking an elusive master terrorist across a landscape drenched with generations of blood, the trail turning on itself until, finally, he can no longer be certain who is stalking whom. And when at last the showdown comes, it will not be Gabriel alone who is threatened with destruction - for it is not his history alone that has been laid bare.
