I remember the mid-'50s well. It was when my life changed, and I left acting to become one of the first female television news reporters in the U.K.

Innocence is ignorance.

The BBC is very good at period drama - world-famous for getting the details right.

I find writing for children much easier. I don't mean it's less demanding - you've got to have a talent for it and you've got to work very hard - but you don't have to pull your guts out and lay them on the line in quite the same way as when you're writing for adults.

The '50s in general are written off as a boring decade following the turmoil of the Second World War and its immediate aftermath - the postwar Labour government, the cold war, the arrival of the New Look in fashion, etc. But I remember it as a very exciting time - a pioneering, rule-breaking time, especially for the young.

I'm not altogether sure what I'm going to do for that. I think it will be a lot more low key than the other two I've done. Dare I say it, a bit more relaxing.

I've had lots of replies, we're into the double figures now. And the overall standard is very good. In fact I've been feeling a little guilty, because I haven't replied to anyone yet - it is something I will be doing.

I've wanted to do it for years, but every attempt at it has turned into another tune. We have actually taken a different approach, we're doing a lot of sampling - we're even sampling bits of Flash!

There's not a moment on it that will sound too familiar, as soon as it sounds comfortably familiar then we like to do something with it to take away that comfortable feeling.
