The Hanging Garden (Rebus #9), Ian Rankin

DI John Rebus is hard at work on multiple cases. Not only is he on the trail of a WWII war criminal - he's also become entangled in a dangerous battle between two rival gangs.

But when his daughter is the victim of an all too professional hit-and-run, there's nothing Rebus won't do to bring down the prime suspect. Even if it means making a deal with the devil . . .
