A detective on the edge. A case that might take him over it . . .
Inspector Jaap Rykel is on the brink, about to leave the force after the burden of past traumas became too much to bear.
Visiting the station for one final bureaucratic task, he stumbles across an investigation into a particularly violent murder - the details of which echo all too closely a case he worked on years before.
But that case was solved. The killer was caught - and is still in prison.
Which means that perhaps Rykel got it wrong. That an innocent man has been locked up, while a vicious murderer has been left to kill again.
Is this his last chance to make things right?
