I will write in words of fire. I will write them on your skin. I will write about desire. Write beginnings, write of sin. You’re the book I love the best, your skin only holds my truth, you will be a palimpsest lines of age rewriting youth. You will not burn upon the pyre. Or be buried on the shelf. You’re my letter to desire: And you’ll never read yourself. I will trace each word and comma As the final dusk descends, You’re my tale of dreams and drama, Let us find out how it ends.

With pornography, if you don't get hard or wet, depending on your gender, it didn't work. With humour, if you don't laugh it didn't work. And with horror, if you don't get scared or haunted, depending on what it's trying to do, it didn't work. I'm fascinated by those three categories.

"Only write what you know" is very good advice. I do my best to stick to it. I wrote about gods and dreams and America because I knew about them. And I wrote about what it's like to wander into Faerie because I knew about that. I wrote about living underneath London because I knew about that too. And I put people into the stories because I knew them: the ones with pumpkins for heads, and the serial killers with eyes for teeth, and the little chocolate people filled with raspberry cream and the rest of them.

Doctor Who has never pretended to be hard science fiction... At best Doctor Who is a fairytale, with fairytale logic about this wonderful man in this big blue box who at the beginning of every story lands somewhere where there is a problem...

Truly, life is wasted on the living, Nobody Owens. For one of us is too foolish to live, and it is not I.

No, look, there's a blue box. It's bigger on the inside than it is on the outside. It can go anywhere in time and space and sometimes even where it's meant to go. And when it turns up, there's a bloke in it called The Doctor and there will be stuff wrong and he will do his best to sort it out and he will probably succeed cos he's awesome. Now sit down, shut up, and watch 'Blink'.

If writing a novel is a year's exile to a foreign country, writing a short story is a weekend spent somewhere exotic. They're much more like vacations, more exciting and different, and you're off.
