The Inner Dark

After four years behind bars, notorious serial killer Tom Kerr is ready to talk.

And Chief Inspector William Wisting is waiting to listen.

Kerr has finally agreed to lead the police to his final victim's grave. But the expedition goes horribly wrong after his escape deep into the Norwegian forest.

Wisting must launch a frantic search to find this cold-blooded killer before he strikes again.

But the body of another woman, killed weeks before, has been found. Murdered in the same way as Kerr's victims.

Is there a copycat killer on the loose?

Has Kerr become a twisted role model for a second killer?

And, if so, what might happen if master and apprentice unite?

As the clock counts down to the next murder, Wisting must put everything on the line to stop a terrifying evil before it strikes again.
