Some material things make my life more enjoyable; many, however, would not. I like having an expensive private plane, but owning a half-dozen homes would be a burden. Too often, a vast collection of possessions ends up possessing its owner.

A pair of Russell & Bromley boots with studs. I have had them for eight years and wear them all the time.

My cello. At the time, in 1983, it was £192,500.

I love clothes and accoutrements, so it would be either a suit or a watch. I love Mark Powell in Soho, and Paul Smith.

An actor. When I was really young, I wanted to be a fishmonger’s wife.

I went to a funeral where they played Cheek To Cheek: Fred Astaire singing “Heaven. I’m in heaven… ” Everyone smiled. I’d like that.

My mother, because I didn’t appreciate until after she’d gone that she was a vulnerable human being. I just expected her to know everything and be everything.

Judith Clark, on whom I based my character in the prison trilogy. She has served over 35 years and turned herself around. She is an inspiration.

In some way your life is doubled. You’re you and the other person.

When I got to 40 and realised I hadn’t read all the books I needed to read to understand the world.
