The BBC have today released promotional pictures for the fourth episode of River the new BBC drama which airs on BBC One this October.

John River (Stellan Skarsgrad) is a brilliant police officer whose genius and fault-line is the fragility of his mind – a man haunted by the murder victims whose cases he must lay to rest. A man who must walk a professional tightrope between a pathology so extreme he risks permanent dismissal, and a healthy state of mind that would cure him of his gift.

Following her recent Emmy-award win for best ‘Writing, Miniseries or Movie’ for BBC Two’s The Hour, Abi Morgan says of her new series:

“River is a fractured mind navigating a brutal world. And he does it wearing a police badge. I can’t think of a better home for it than the BBC. The chance to tell big stories in a bold way on a channel that embraces so many writers, directors and actors I admire and respect is a huge treat.”

Nicola Walker (Last Tango In Halifax) plays River’s colleague and confidant, Detective Sergeant Jackie ‘Stevie’ Stevenson, with Adeel Akhtar (Utopia) as Detective Sergeant Ira King. Lesley Manville (An Adventure In Space And Time) will play their superior, Chief Inspector Chrissie Read. Eddie Marsan (Ray Donovan) also joins the cast as a notorious killer who haunts River.

The fourth episode is set to be broadcast on Tuesday the 3rd of November from 9:00pm to 10:00pm. Below are more promotional pictures as well as the synopsis for the fourth episode.

The more secrets River uncovers, the greater his confusion – until he discovers the surprising identity of the person Stevie spoke to on the night she died. Has he blown the case wide open?
