Sometimes during a conversation with a journalist - where you are answering things you never normally talk about, not even with some of your closest friends - you end up being quite confessional, and you don't think about the amplification of that. No matter how fancy these journalists are, they have editors or political leanings behind their publications, which means that, basically, they're going to shape what you've said into an article they've already written. So you have to be really careful with your words.

I'll always do 'Sherlock' - it's something I'm not going to give up on.

I got live tweeted once by someone who was opposite my home in some rented accommodation. He was actually describing on twitter what I was doing. 'I took a shirt off, I went to the window, I put a shirt back on... ' And I've got blinds in my flat!

Fame is a weird one. You need to distance yourself from it. People see a value in you that you don't see yourself.
