肝胆俱裂 (Torn Apart)

Everyone understands about the no-go districts--areas of the city so overrun with gang violence even the police stay away. In this book, the first in a new series, DI Hero Nelson sets out to combat the issue. When Saskia Hartley and her nine-year-old son are run down outside a restaurant, DI Nelson knows it is no ordinary hit-and-run incident. He's looking at a homicide case... and the evidence points to the brutal Krull Gang. When two prostitutes are murdered, but little interest is given to the women on the Krull's payroll, Nelson connects the dots. DI Nelson has to decide whether he's dealing with a turf war or something far more sinister.
