Mark Watson on 'The Knot' and being a stand-up 'veteran'

We spoke to comedian Mark Watson about life on tour and his new novel 'The Knot' about a family with a dark secret.

Mark also tells us the differences between his two jobs as a writer and stand-up and how social media impacts on them both.

Mark's book 'The Knot' is out now, and he's on tour until the end of November.
