A killer targeting people of Asian descent in a city fed by xenophobia and intolerance threatens a race war in this crime thriller set in London  London is angry, divided, and obsessed with foreigners. A dead Asian and some racist graffiti in Chinatown might trigger the race war that the white supremacists of the Make England Great Again movement have been hoping for. They just need a tipping point. And he arrives in the shape of Detective Inspector Stanley Low. He's brilliant. He's bipolar. He hates everyone almost as much as he hates himself. Singapore doesn't want him and he doesn't want to be in London for a criminology lecture. There are too many bad memories, like Detective Sergeant Ramila Mistry, who asks for Low's help. The dead Asian was Singaporean. Against everyone's better judgement, Low is plunged into a polarized city, where xenophobia and intolerance feed screaming echo chambers. His desperate race to find a far-right serial killer will lead him to charismatic Neo-Nazi leaders, incendiary radio hosts, and Metropolitan Police officers who don't appreciate the foreigner's interference. No one wants him there, but too many victims with Asian faces keep him there. He craves vengeance, particularly when the murderer makes it personal and promises to kill the only woman that Low ever loved. The Chinese detective is the wrong face in the wrong place. But he's the right copper for the job. London is about to meet the bloody foreigner who won't walk away.
