Night after night, cars are set alight across the German city of Hamburg, with no obvious pattern, no explanation and no suspect. Until, one night, on Mexico Street, a ghetto of high-rise blocks in the north of the city, a Fiat is torched. Only this car isn't empty. The body of Nouri Saroukhan--prodigal son of the Bremen clan--is soon discovered, and the case becomes a homicide. Public prosecutor Chastity Riley is handed the investigation, which takes her deep into a criminal underground that snakes beneath the whole of Germany. And as details of Nouri's background, including an illicit relationship with the mysterious Aliza, emerge, it becomes clear that these are not random attacks, and there are more on the cards.
