British assassin John Milton has blood on his hands and he decides to quit. Trouble is, his job isn't one you can just leave.
As a rival agent seeks to bring him to heel, Milton gets involved with a single mother in the East End of Hackney, trying to save her son as London burns through the riots of 2012.
John Milton considers himself an artisan. A master of killing.
Milton is 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 has taken its toll. Milton is troubled by nightmares, a long line of ghosts tormenting 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.
Sharon Warriner is a single mother in the East End of London, suicidal with fear that she's lost her young son to a life in the gangs. After Milton saves her life, he promises to help. But the gang, and the charismatic rapper who leads it, is not about to cooperate with him.
As London burns through summer riots, Milton finds himself in unfamiliar territory, dealing with an unfamiliar foe. And when his employer sends another agent after him, the odds against him are stacked even higher.
