Bad Wolf - Nele Neuhaus

In Bad Wolf, Nele Neuhaus's second U.S. publication of her enormously popular series, tensions run high both inside and outside police headquarters, and a complex and unpredictable plot propels her characters forward at breakneck speed.
On a hot June day, the body of a sixteen-year-old girl washes up on a riverbank outside of Frankfurt. She has been brutally murdered and shows signs of long-term abuse, but no one comes forward with any information as to her identity. Even weeks later, the local police have not been able to find out who she is.
Then a new case comes in: A popular television host is attacked, raped, and locked in the trunk of her own car. She survives, barely, and is able to supply only vague hints to the police, having to do with her recent investigations into an organization whose members are from the highest echelons of society, and the potential uncovering of a shocking history they'd prefer to keep from the public eye.
As the two cases collide, Inspectors Pia Kirchhoff and Oliver von Bodenstein dig deep into the past and underneath the veneer of bourgeois society to come up against a terrible secret that is about to impact their personal lives as well. It is almost too late for a person very close to Pia before she and Oliver finally track down the big bad wolf. . . .
