The official synopsis reads: “John River 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.”

Charlotte Moore, Controller, BBC One commented: “River is full of intriguing twists and turns and I was truly gripped when the script came in. Abi’s one of Britain’s most distinctive and original storytellers and her ability to push the boundaries of the genre in surprising ways makes River her perfect debut on BBC One.”

Ben Stephenson, Controller, BBC Drama Commissioning added: “It was amazing to see Abi winning the Emmy in LA on Sunday night – it shows what a world class talent she is. I am delighted that she will now be turning her attention to her first series for BBC One. It’s a corker with all Abi’s unique qualities – smart, moving, warm and full of huge surprises.”

The six-part series begins filming in London next year and will air on BBC One in 2015.
