‘I’m very fortunate that I began my writing career proper when I was still acting, and that means I had to write wherever I was… If I was in Scotland making a series or somewhere waiting to catch a plane, that’s where I had to write. And I never lost that. I write in the country, I write in London. I write in the House of Lords – they give me a little cupboard with a desk in it, and I can shut the door and write there.
‘So basically I write when I can.’
