John Milton is an artisan. A master of killing. He’s the man the British government calls on to eliminate the worst of the worst: the enemies of the state that MI5 and even the military can’t stop. But years of state-sanctioned murder have taken their toll. Milton is troubled by nightmares, a long line of ghosts who torment his dreams. He resolves to make his next job his last and, then, perhaps, he can start to make amends for everything that he has done.
