Girl Zero 
'Outstanding - relentless, multi-layered suspense and real human drama' - Lee Child
There are some surprises that no-one should ever have to experience. Standing over the body of your beloved - and murdered - niece is one of them. For Detective Inspector Harry Virdee, a man perilously close to the edge, it feels like the beginning of the end. His boss may be telling him he's too close to work the case, but this isn't something that Harry can just let lie. He needs to dive into the murky depths of the Bradford underworld and find the monster that lurks there who killed his flesh and blood. But before he can, he must tell his brother, Ron, the terrible news. And there is no predicting how he will react.
Impulsive, dangerous and alarmingly well connected, Ron will act first and think later. Harry may have a murderer to find but if he isn't careful, he may also have a murder to prevent.
