"Hearing of a British Jihadi returning from Syria with murderous plans, Jonas sends out for a telling photograph - a crocodile, almost submerged, just its eyes above water as it waits for unsuspecting prey to drink at the riverbank. Coming ashore near Dover, Cameron Jilkes is a young man from a broken home and a failed education, trained in the harshest theatre of war, driven to rage by loss and pain. And this time, 'the eternal flame' must go out - to hunt the crocodile himself."
