Being the only writer on a successful show is very rewarding.

Like most writers, I write about what has happened to me as that involves the minimum amount of research.

The Doctor: Oh, now what's this, then? I love this. A big, flashy-lighty thing. That's what brought me here. Big, flashy-lighty things have got me written all over them. Not actually, but give me time... and a crayon.

The way you get your script to the right people is that you put it in an envelope. It's easy. The difficult bit is writing something that is so good people will take a punt on a brand new writer.

It’s been a long time since Sherlock Holmes jumped off that roof - it’s time to reveal the truth about what happened between him and the pavement.

I don't want to think that the stories are finite; I want to feel that they can go on forever.

So is this how it works Doctor? You never interfere with the affairs of other peoples or planets, unless there are children crying?
