DCI Banks - Season 4

The officers are dismayed to learn the arson attack on the Osgoods' house has injured Michael and killed his son Robbie, and local bully Gary McCready is soon questioned. As the investigation into Katrin's murder continues, the body of an older man who died of natural causes is found buried near her grave, and when Banks suspects Jason McCready abducted missing Annika, he uncovers a shocking secret. Meanwhile, the detective gives a moving speech at his mother's funeral, and the ceremony brings him closer to his father.

When the body of eminent lawyer Anaan Kamel is found washed up by an underground river, suspicion falls on Marcus Layton, a former employee of the victim's chambers. Text messages suggest an affair that had progressed to blackmail, but Banks and Morton struggle to find further information about Marcus. And when his corpse is found upstream in what looks to be a contract killing, the case becomes much more complicated.

With Geoff now a marked man, he and daughter Evie are put under watch at a hotel while the search for Mullen is widened. However, when the suspect follows Evie's boyfriend to the location and sets off the fire alarm, he draws Geoff and Evie outside. Meanwhile, Banks believes loan shark Hargreaves is behind the hit on Marcus, and manages to extend his stay in the cell, despite having very little evidence against him.

When the body of student Josh Tate is found dumped in a ravine, the investigation into his stabbing uncovers a very different man to the quiet character described by his roommate Spencer. Meanwhile, DI Morton's ex-lover Martin Hexton has arrived, claiming to be working on a local case.
