I get nice letters, but really I have no idea. I just try to enthuse people. You've been married for 31 years.

I never get bored of my wife. It's lovely.

I was very inventive. I lived in my own world - my dad said I was a loner. Not lonely, just happy in my own company. It's the same now. I need time alone, which is maybe why I love to write. Having said that, I love the sociability of telly. It's a nice contrast.

Oh, and I have to mention one lady who does all of my book covers in cross stitch and frames them. Muriel. She's amazing. I just received one for my latest, Love And Dr Devon, actually. It's very sweet of her to do it.

Georgian England, to see those wonderful houses being built. And the clothes were interesting too, although I wouldn't want to wear a wig. It's also the most beautiful period of English landscape gardening. They had famous gardeners like Capability Brown.

I don't spend much on clothes. I buy old books. I tell myself I ought to save - it's the classic Northern work ethic. I like good holidays, though. I'm a big fan of cruises. I love unpacking once and having the scenery change every day.

My wife and I always have a winter holiday that I call the "fly and flop". In January and February, you don't want culture, you just want to get your bones warm and eat, drink, sleep. We usually go to the Caribbean.
