I love Paris for its wide boulevards and cafes, and Rome for the ancient history, as seen at the Forum.

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.

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.

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 wish we could grow up about it, I'm sure we are contributing to global warming, and we must do all we can to reduce that, but our climate has always changed. The Romans had vineyards in Yorkshire. We're all on this bandwagon of 'Ban the 4x4 in Fulham'. Why didn't we have global warming during the Industrial Revolution? In those days you couldn't have seen across the street for all the carbon emissions and the crap coming out of the chimneys.

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.

You hope people won't be tricky or miserable. If you're in public life, it's important not to be. If someone says, 'I like your programme, thank you,' you should be grateful. I am. Why be nasty?
