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.

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 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.
