When a man and a woman claiming to be social workers come to Katy Heath’s house and tell her that they need to take away her son Kyle, Heath complies. But when they fail to return her son and are unknown by social services, DCI Banks is quickly drawn into a full-scale search for the missing boy. Why has Kyle been abducted and what are the chances that he can be found alive?

When an investigative journalist is found dead in a holiday chalet in a remote village, Banks and his team are initially confronted by an overwhelming number of leads. As Banks identifies a connection between Barber and a mysterious death in the 1980s revolving around the surviving members of pop band ‘The Crystal Kiss’, he must begin to unpick decades of lies.

In the final story of the series, a terrible chain of events is set in motion by the discovery of a loaded gun in a young girl’s bedroom, ultimately putting Banks’ daughter in mortal danger and sparking an internal investigation that threatens to break up Banks’ team.

Elsewhere Detective Annie Cabbot returns from a year’s maternity leave – is it time for Banks to admit how he really feels about her? Or will work prevent the two from ever getting together?

DCI Banks airs from Friday, 24 October at 20:00 on BBC Entertainment, channel 120 on DStv.
