I know this is going to sound very self-serving, and I apologize for it, but if you can write comedy, you can pretty much write anything, because it's the hardest. It's the most technically demanding, the most precisely evaluated form of writing. People know if it works or not. There's a big button marked 'fail,' and that's when nobody laughs.

The story of Sherlock Holmes, on the surface, is about detection, but in reality, it's about the best of two men who save each other - a lost, washed-up war hero and a man who could end up committing murders instead of solving them. They come together. They become this perfect unit. They become the best friendship ever, and they become heroes. That's what we fall in love with, not Sherlock on his own. No one can love that man on his own, but Sherlock Holmes and Dr. Watson - the best friends ever.

River Song: Right, I have questions. But number one is this: what in the name of sanity have you got on your head? The Doctor: It's a fez. I wear a fez now. Fezzes are cool.

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

See the bowtie? I wear it and I don't care. That's why it's cool.

Reinette: One may tolerate a world of demons for the sake of an angel.

Madness is just what a genius looks like to a tiny mind.
