[1] The six-part series stars William Ash, David Warner, Ian Puleston-Davies, Reece Dinsdale, Nicholas Gleaves, Laura Fraser, Jason Watkins and Zoe Henry.
All three of the Fairburn siblings are involved with law enforcement: brothers Chrissie (William Ash) and Ray (Nicholas Gleaves) are police officers, while their sister Beth (Zoe Henry) works as a lawyer.
Beth, Chrissie and Ray's widowed father Lenny (David Warner) is a retired police officer who berates the political correctness of his children's modern methods: he himself is fighting a losing battle with Alzheimer's disease and struggling to come to terms with the fact that he can no longer be the strong and authoritative head of the family.
The other members are the solitary but insightful Robert (Reece Dinsdale); Lucy (Laura Fraser), the newest recruit, with a need to prove herself; and the volatile family man Joe (Ian Puleston-Davies), an 'old school' officer with a barely contained temper and a tendency to both bully Chrissie and clash with the "by-the-book" Ray.
[1] Conviction was described by the BBC as a drama which "explores the notion that everyone has the ability to kill and what it is that can trigger that reaction in any of us (using) the volatile and dangerous world of the CID as a backdrop to show how a group of very real characters are affected practically, mentally and emotionally by what they have to face on a daily basis.
This wasn't me and Marc (Munden, the director) indulging some arty idea but looking for ways to crank up the tension, to delight in the storytelling and keep the thing moving at a real pace.
