My own grandfathers were a submarine commander and a 'desert rats' tank operator in the Second World War.

I'm excited to see where the Illuminati and whatever else might happen, how that works, and where it ends up.

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

It's very easy to be cynical about any kind of interference in things that are beyond our skill set.

'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.

I'm still very sensitive and wary of people recognising me The only thing that really annoys me is people trying to surreptitiously take a photo on their phone without asking. I feel it's cowardly and a bit pathetic. Just ask me if you really want me to have a photograph with you.

I never really got obsessed about one thing for long. I was a bit of a butterfly and a magpie.
